Description

  The present invention relates to a system and a program that recognize a voice of a passenger of a vehicle and execute a predetermined process.

  Currently, in-vehicle electronic devices having functions such as a navigation device and a radar detector are widely used. Such an in-vehicle electronic device has a function of outputting various information required by a user who is a passenger of the vehicle while the vehicle is running.

  For example, when the in-vehicle electronic device has a function as a navigation device, a guide route to a searched destination and various searched facilities can be displayed on a display device according to a user operation. . Further, for example, when the in-vehicle electronic device has a function as a radar detector, targets such as an orvis, a control / inspection area, and a traffic monitoring device can be appropriately displayed on the display device.

  The operation of such an in-vehicle electronic device is basically performed by a user manually operating a switch provided on the device, a touch panel configured on a screen of a display device, and a remote control capable of remote control by infrared rays. Do. Further, in-vehicle electronic devices having a voice recognition function of recognizing a voice uttered by a user and performing a process in accordance with the voice have been widely used.

  By using this voice recognition function, even users who have difficulty in manual operation while driving are able to speak recognition words corresponding to pre-registered commands, etc. Various functions can be executed.

JP 2009-115594 A

  However, the voice recognition function of the conventional in-vehicle electronic device is not different from the manual operation in that the device performs a predetermined process in response to an instruction unilaterally issued by the user. For this reason, the user can only feel that he or she is operating a tasteless device irrespective of manual operation or voice input.

  In addition, general in-vehicle electronic devices also have a function of performing route guidance, notification of a target, and the like by using a preset voice. However, this function is no different from providing information by screen display in that the device side provides information unilaterally. For this reason, the user can only obtain a feeling that information is obtained from the tasteless device.

  As described above, with the conventional technology, only the feeling of operating the device can be obtained, so there is no fun there, and people in the vehicle, especially drivers who drive alone for a long time, Very boring. For this reason, after a lapse of time from the purchase, the user is less motivated to actively use the in-vehicle electronic device, and often the various functions are not effectively used.

  The present invention has been proposed in order to solve the above-mentioned problems of the prior art. The purpose of the present invention is to provide a user with an interesting operation and driving, and to be tired without being bored. It is an object of the present invention to provide a system and a program that motivate users to use functions.

(1) The system of the present invention responds to a dialogue between recognition information based on a result of recognizing a voice of a user who is a vehicle occupant and output of a voice of a predetermined character indicating that the user's voice has been recognized. And performing a function required by a passenger of the vehicle.
In this way, for example, the system does not execute a function in response to a unidirectional instruction of a user who is a vehicle occupant, but the user interacts with the character, so that the vehicle occupant needs it. Since the functions can be executed, the convenience and fun of operation and driving are increased, and the feeling of communication with the character is obtained, so that the user is not tired. Further, for example, the user is motivated to operate the system in order to interact with the character, so that the functions of the system are effectively used.
The recognition information based on the result of recognizing the user's voice may be, for example, information that recognizes a voice uttered by the user as a phrase that establishes a conversation with the character. By doing so, for example, by outputting the voice of the character in accordance with the recognized phrase, it is possible to indicate that the voice of the user has been recognized and to establish a dialogue with the user. As for the recognition of words, for example, in order to execute a function required by the passenger of the vehicle, a specific recognized word and the voice of a character with which a dialogue is established in relation to this are registered in advance, and the user's voice is recognized. It is preferable to output the voice of the character depending on whether or not the result matches the voice recognition result. In this way, for example, by preparing various combinations of the recognized words for dialogue and the voice of the character, it is possible to cope with various processes to be executed in accordance with the combinations.
As the predetermined character, for example, it is preferable that a voice that is output from the system recognizes a speaker having a specific personality. By doing so, for example, the user can have a feeling as if he or she is interacting with an actual person, so that the user can be friendly.
As the dialogue, for example, at least one round trip exchange of starting a speech, responding to the speech, and responding to the response may be performed. In this way, for example, instead of the system simply performing the processing according to the user's command, the feeling that the character intervenes between himself and the system and provides the service can be obtained. Good. Further, as the dialogue, for example, it is preferable that the utterance of the user and the voice of the character have the meaning and content formed as an utterance and a response thereto. In this way, a feeling of mutual communication can be obtained. Further, as the dialogue, for example, an utterance and a response in which the meaning content thereof is inappropriate may be used. By doing so, the user may feel interesting and unexpected. Further, as the dialogue, for example, a case where the utterance and the answer to the utterance are satisfied as semantic contents and a case where the meaning contents for the utterance are inappropriate are mixed. In this way, it is possible to produce an imperfection close to a real conversation, and to make the user feel human.
The function required by the vehicle occupant may be, for example, a function that enhances the convenience of the vehicle occupant in changing settings, outputting information, and the like.In particular, for example, the information that the user wants to know is output. And a predetermined process. The information that the user wants to know may be, for example, information that can be output to the system more easily or quickly than by manual operation by using voice recognition. In this way, for example, since the user actively uses the speech recognition, the system may provide the user with more opportunities to interact with the character.
As the function required by the occupant of the vehicle in response to the interaction, for example, the function required by the occupant of the vehicle may be executed as a result of the interaction. In this way, the user of the vehicle will be motivated to interact with the character in order to execute the required function. In addition, executing the function required by the vehicle occupant in response to the interaction may include, for example, executing the function required by the vehicle occupant during the interaction. By doing so, the willingness of the user to speak and carry out the dialogue in order to execute the function required by the vehicle occupant may be increased. Further, executing the function required by the vehicle occupant in response to the dialog may be, for example, executing a process of outputting a voice of a character constituting the dialog. In this way, since the user wants to hear the voice of the character and interacts, the user can enjoy the dialogue itself.

The predetermined process for outputting the information that the user wants to know in response to the dialog may be a process for outputting information required by the driver while the vehicle is driving.
In this way, even when it is difficult for the driver to obtain desired information while driving, for example, due to difficult manual operations or limited manual operations, the character recognition can be performed by using voice recognition. Desired information can be obtained while enjoying conversation with the user.

The predetermined process for outputting the information that the user wants to know in response to the dialog may be a process for outputting the information through a plurality of selections.
In this way, for example, when multiple selections need to be made in order to output information, operation by voice input is more user-friendly than when manual operation is required for each selection. It will be simple.
The information output through a plurality of selections may be, for example, information having a hierarchical structure or information that cannot be output unless a plurality of operations are performed. Such information may reduce the burden on the user as compared with performing the manual operation a plurality of times.
In particular, as information output through a plurality of selections, for example, information obtained by sequentially narrowing down from a plurality of candidates, such as a facility search and a current location search, may be used. The process of outputting such information is different from, for example, an operation for moving the vehicle itself, such as a brake or an accelerator, or an operation for notifying something externally for safety while traveling, such as a blinker. Since it is difficult to execute the operation directly by manual operation, it may be suitable for operation by voice recognition.

As part of the dialogue, if there is a next selection, it may be the voice of the character that guides it.
In this way, for example, the user may be prompted by the voice of the character to make a selection, so that the predetermined process may be sequentially performed.
The voice of the character that guides the user to the next selection may be, for example, a voice that asks for the destination, such as “Where are you going?” When the voice of the user “Nearby” is recognized in the peripheral search. In this way, for example, the user can clearly know what to say next.

If there is no next selection as part of the dialogue, it may be a voice of a character indicating this.
By doing so, for example, the user knows that it is no longer necessary to proceed with the process further, so that the user can make a decision such as ending the instruction or performing another process.
As the voice of the character indicating that there is no next selection, for example, when the voice of the user “Familys” is recognized in the neighborhood search, the next selection is “Do you go to the family alone?” It may be a sound that clearly indicates that there is no such thing. In this way, the user knows that it is not necessary to proceed to the next step and can request the user to make another determination.

The predetermined process for outputting information that the user wants to know in response to the dialog may be a process for displaying information about facilities around a desired point on the display means.
By doing so, for example, the user can acquire information about the surrounding facilities while enjoying a dialogue with the character, without the need for cumbersome manual operations for obtaining information on the surrounding facilities. .

As a predetermined process for outputting information that the user wants to know in response to the dialog, an icon indicating the peripheral facility is displayed at the position of the peripheral facility on the map displayed on the display means, by comparing the icon with the map. It may be characterized by being relatively highlighted.
In this way, for example, information on facilities required by the user becomes conspicuous on the map, so that the user can easily grasp the location of the facility, and serves as a guide when selecting a desired facility by voice. So good.
As the relative highlighting as compared with the map, for example, it is preferable to display the location of the facility clearly. For example, if at least one of the brightness, the saturation, and the hue of the icon and the map is changed, the contrast between the two may be noticeable. In particular, for example, if the icons are displayed in color and the map is displayed in gray scale, the icons can be seen very clearly.

In response to the dialogue, as a predetermined process for outputting information the user wants to know, an icon indicating the peripheral facility is displayed at the position of the peripheral facility on the map displayed on the display means, and the icon In addition, it is preferable that a display that can distinguish the ranks according to a predetermined standard is displayed.
In this way, for example, a display that can distinguish the order of the icons can be used as a guide for the user to select a facility.
As the predetermined criterion, for example, the order may be closer to a specific point. This makes it possible to intuitively understand which facility is closest to the case where the facility name is displayed. Further, the predetermined reference may be, for example, a descending order of importance to the user. In this way, the facility that the user wants to know most may be preferentially displayed. The importance for the user may be, for example, that the user has performed in the past, that the user has performed frequently in the past, or that the user's preference is met. In this way, the user can quickly know the facility he wants to go to. In addition, for example, those that have been performed in the past but do not want to go again and may be excluded from the importance of the user may be excluded. In this way, for example, only items that the user may go to may be displayed.
The display that can distinguish the order may be, for example, information that originally indicates the order, such as a number or an alphabet. In this way, for example, the meaning of the rank can be easily grasped. Further, the display that can distinguish the ranks may be information that visually indicates the ranks, such as, for example, shapes such as 、, △, Δ, and ×, or a stepwise change depending on brightness, saturation, and hue. In this way, for example, the order can be visually and intuitively grasped.

The voice of the character that prompts the user to select the searched facility may be output with the content corresponding to the displayed icon.
By doing so, for example, the selection of the facility can be prompted by the voice of the content corresponding to the displayed icon, so that the user can grasp the content visually confirmed by the voice.
The contents according to the displayed icon include, for example, a voice for asking what number is better if it is a number, a voice for asking what is better in the alphabet if it is an alphabet, and asking what the shape is if it is a shape. If it is a voice or a color, it may be a voice inquiring about what the color is. In this way, the user can easily understand, for example, what to utter and select the facility. In addition, for example, the content corresponding to the displayed icon may be sound indicating the range of the selected candidate. Thus, for example, if the voice is output from what number to what number, the user can grasp not only the content to be uttered but also the range to be selected.

When the voice of the user selecting one of the facilities is recognized based on the content corresponding to the displayed icon, a route searched from a specific point to the selected facility may be displayed on the display means.
In this case, for example, the user can easily select the content according to the displayed icon, rather than selecting the facility name.
The contents according to the displayed icons include, for example, the number of the icon of the desired facility if the number, the alphabet of the icon of the desired facility if the alphabet, and the shape and color of the icon of the desired facility if the shape. If so, the color of the icon of the desired facility may be used. In this way, for example, the facility can be selected using words that are easier to remember than the facility name.

After the searched route is displayed on the display means, it is preferable to determine whether to start the route guidance or to search the route again according to the dialogue.
In this way, for example, when the user does not want the searched route, the user can instruct the user to search again while interacting with the character, thereby reducing the trouble and boring feeling when starting again. I can do that.

As a predetermined process for outputting the information that the user wants to know in response to the dialogue, which of the items corresponding to the recognition words registered in advance for recognizing the voice should be used as a recognition word. A table of items to be selected may be displayed on the display means.
In this way, for example, if the user selects only frequently used items from the displayed list of items, the recognition words are limited, so that erroneous recognition can be reduced.
The selected recognition phrase may be registered in a predetermined memory area, for example, by rewriting from a default state, putting it in an empty area, or rearranging the already contained words. In this way, the limited memory area can be effectively used.

A table of items that allows the user to select which of the items corresponding to the recognition words registered in advance for recognizing the voice of the user as the recognition words for the dialogue is displayed on the display means, The item selected from the table may be set for each page to be displayed on the display unit.
By doing so, for example, even if the items that can be displayed on one page of the display screen of the display means are limited, the items frequently used by the user can be brought to the top page. This eliminates the need to switch pages for display.

It is preferable that the item of the recognition phrase that is likely to be confused is set to be displayed on another page.
In this way, for example, words that include similar sounds, words that are likely to be confused when actually recognized, and the like are not lined up on the same page and are simultaneously candidates for recognition. It is good because it can be reduced. Words containing similar sounds include, for example, the same 50 sounds and the same kanji, such as “family restaurant” and “fast food”, “hospital” and “beauty salon”, and “Western food” and “Japanese food”. It should be a phrase that includes. In this way, since the sound recognition phrase that is confusing even from the character is not displayed on the same page, the user also needs to input one of them, thereby reducing erroneous recognition. A phrase that is highly likely to be confused when actually recognized may be, for example, a different phrase recognized for the same utterance based on a record of past recognition results. In this way, for example, it is possible to exclude a combination in which erroneous recognition has actually occurred on the same page.

The item corresponding to the recognition phrase has a large item corresponding to a recognition phrase including a plurality of concepts, and a middle item corresponding to a recognition phrase corresponding to the plurality of concepts. Should be displayed on the screen.
In this way, for example, even when the user wants to search for the middle item, there is no need to change the hierarchy or the page, so that the desired item can be directly selected.
The large item may be a high-level concept item including many candidates, such as “hospital”. This is convenient for a user who wants to search from as many candidates as possible. The middle item may be, for example, a lower conceptual item that contains fewer candidates than the large item, such as “internal medicine” and “pediatrics” included in the concept of “hospital”. In this way, it is convenient for a user who wants to immediately obtain information on a desired facility from a small number of candidates.

It is preferable that a phrase related to a phrase displayed as an item but not displayed as an item is registered as a recognition phrase.
In this way, for example, it is sufficient to say a phrase related to the recognized phrase without uttering the recognized phrase itself displayed in the item. Even if you are unfamiliar with, you can search.
A phrase that is related to a phrase displayed as an item but is not displayed as an item may be, for example, a middle item that corresponds to a large item displayed on a specific page but is not displayed on that page. .
In this way, for example, even if the middle item is not displayed, if the user speaks the middle item, the middle item is searched, so that necessary facility information can be quickly obtained.

The character may be displayed on display means as a predetermined process for outputting information desired by the user in response to the dialogue.
By doing so, for example, the user can see the figure of the person with whom the user is interacting on the display screen, so that the user can feel familiar and want to actively use the system to see the figure.

As a predetermined process for outputting information that the user wants to know in response to the dialog, the character may be displayed at a position on the map that does not obstruct the displayed route display.
In this way, for example, the display of the searched route can be maintained while the display of the character is enjoyed.
As the position where the route display is not interrupted, for example, the character and the display of the searched route may be located on opposite sides of the display screen. In this way, the user can be made to feel as if the character does not disturb the route search service, so that the user may have a better feeling.

The character may be moved while displaying the searched route on the map so as not to obstruct the displayed route.
In this way, for example, by continuing to display the moving character, the user can feel annoyed and appeal to the presence, and for a user who wants to continuously watch the character, enjoy the movement of the moving character May be able to.

The display area of the item corresponding to the recognition phrase of the user's voice has a portion where the background image is visible, and the character displayed on the display means is larger than each item and does not have a portion where the background image is visible. The display area of the item may be closer to the position on the display screen opposite to the character.
In this way, for example, when the character moves to the opposite side of the searched route, the display area of the item may overlap the searched route, but each item is smaller than the character. Since the display area of the item has a portion where the background image can be seen, the background image can be easily viewed rather than the searched route overlapping the character.
The part where the image behind can be seen may be, for example, a transparent part or a part with a gap. In this way, for example, the background image can be viewed while ensuring the visibility of the item display.

The voice of the user's name registered in advance may be inserted into the voice output by the character in the dialogue.
By doing so, for example, the user can feel more familiar with the character by being called by his / her own name in the conversation.
It is preferable to insert the voice of the user's name registered in advance into the voice output by the character at the start of the dialogue.
In this way, for example, at the start of the dialogue, the user is called by his / her own name, so that the user's attention may be attracted.

When the voice including the character's name is recognized, the voice of the user's name registered in advance may be inserted into the voice output by the character.
In this way, for example, since the names are mutually called, the user can obtain a more intimate feeling.

As the dialogue progresses, the frequency of inserting the user's name into the voice output by the character may be reduced.
In this way, for example, although the name is initially called, the frequency of the calls is reduced thereafter, so that it is possible to produce a conversation between two people who are accustomed to each other.

Voice data corresponding to the Japanese syllabary is registered in advance, and the voice of the name selected by the user from the Japanese syllabary may be inserted during the conversation.
In this way, for example, the memory capacity can be saved as compared with a case where a plurality of names are registered in advance.

As the voice of the character, it is preferable to insert a voice indicating the status of the character.
In this way, the user can hear the character's situation.For example, if the character is in a negative situation, the user can be made to take care of the character, and if the character is in a positive situation, This can make the user feel the sympathy of the character.
The statement indicating the status of the character may be, for example, a statement that indicates whether the user is in a positive state or a negative state, such as "I am busy." In this way, for example, the system does not unconditionally follow the user's instructions, but can give the user a feeling of concern and empathy, such as a conversation with an actual human. It's good because it gives you a feeling.

The voice of the character in the dialog may be randomly selected and output from a plurality of different phrases set in advance, excluding the already output phrase.
In this way, for example, the same phrase can be prevented from being output, so that the user does not get bored.

A list in which a plurality of different response phrases are registered for a common recognition phrase may be set.
In this way, for example, even if the user utters common content, the character replies with a different expression, so even if the same process is performed many times, enjoy the response from the character. Can be.

It is preferable that a plurality of the lists are set, and there is a list in which phrases different from other phrases are registered even in the same list.
By doing so, for example, a foreign phrase is output as a response to the user's utterance having the same content, so that an unexpected impression can be given to the user. Can be prevented from coming.

It is preferable that the same character has a plurality of display modes even for the same person, and a different phrase is registered as an output voice for each of the plurality of display modes.
In this way, for example, even the same character has different utterance contents according to a plurality of display modes, so that it is possible to enjoy the change while having a conversation with the same person.
The plurality of display modes may be, for example, a standard one, a one transformed by changing clothes, a hairstyle, and the like, and a one different in head and body. In this way, for example, various impressions such as mature, childish, cute, and beautiful can be given to the user, and the user can be bored.

It is preferable that a phrase to be output when the voice recognition is incorrect is registered.
In this way, for example, even if the recognition is mistaken, the user can recognize that the conversation with the character is continuing by returning some phrase.

It is preferable that a phrase to be used as an escape route in case an error occurs in voice recognition is registered.
In this way, for example, there is a possibility that an error occurs in voice recognition, but even if an error occurs, the frustration and anger of the user can be alleviated by the escape opening of the character.
As an escape word, for example, an expression indicating the desire to accurately recognize, such as "I will do my best for speech recognition. I may not be able to recognize 100%", and an expression indicating that it is difficult to achieve completeness Good. In this way, for example, rather than simply indicating that recognition is not possible, psychology that is acceptable to the user for erroneous recognition can be generated.

When there is a user's voice input indicating that the content that the user desires to reply and the content of the character's voice output are different, it is preferable that a response phrase from the character is registered in response to the user's voice input. .
In this way, for example, when the user points out a mistake in the character, the character responds to the mistake, so that when the misunderstanding is misunderstood, it is possible to enjoy the natural exchange between the people.

It is preferable that a phrase serving as an advertisement is registered.
In this way, for example, the user can be guided to the affiliated facility.

As the voice of the character in the dialogue, it is preferable that a phrase about the cause of performing at the facility where the user goes is registered.
By doing so, for example, by speaking about the cause of the decision to go to a certain facility, the user heading to the facility can easily listen.
For example, the user's attention may be drawn whether the cause of the destination is unfavorable to the user or to the user.
The facility that causes the destination to be unfavorable to the user may be, for example, a facility related to the user's illness, such as “hospital”, “dentist”, or “pharmacy”.
As a facility that is preferable to the user for the cause of going to the destination, for example, a facility such as “department store”, “sushi”, and “eel” which has a slightly higher hurdle than a facility that is frequently visited may be used.
Examples of phrases that cause the character to cause various emotions to the user include, for example, "Isn't it somehow bad? Are you okay?" Or "Don't overdo it." It should be a phrase that makes you feel. In addition, for example, a phrase that causes the user to regret, such as "Do you brush your teeth properly?"

As the voice of the character in the dialogue, a phrase serving as a positive or negative advice on what to do at the facility where the user is to go may be registered.
In this way, for example, the user can determine what to do or not to do at the destination based on the advice of the character. Positive advice may be a phrase that recommends something, for example, "I'd better get plaque once in a while." In addition, as a negative advice, for example, a phrase that prohibits something, such as, “Do not have a painful face. It is a man who can put up with a cool face.”

As the voice of the character in the dialogue, a phrase that is a one-sided impression of the character about what to do at the facility where the user is to go may be registered.
In this way, for example, the impression of the character can be obtained, so that the user can refer to the action at the destination.
As a one-sided impression of the character, for example, a positive impression such as “black pig char siu that melts in your mouth. In this way, the user may want to take a similar action at the facility. In addition, for example, a negative impression such as “Do you go to a restaurant alone? Do you feel lonely? In this way, the user is encouraged to change the destination. Further, for example, a positive impression and a negative impression may be mixed, such as "It seems to be fun just to look around the shopping mall, but seems to be tired." In this way, the user can be prepared for the situation at the destination in advance.

It is preferable that a phrase that suggests that the character actually exists is registered as the voice of the character in the dialogue.
In this way, for example, the user may have a feeling that the character actually exists.
Phrases that remind you that they actually exist are, for example, "I'm happy to take me on a business trip ~", "Where are we staying?" It should be a phrase reminiscent of In this way, for example, the user may have a feeling of being always with the character.

(2) A recognition phrase registered in advance for recognizing a user's voice may be displayed as an item.
In this way, for example, the user may know what to say by looking at the displayed item in order to execute the predetermined process.

(3) Recognized words registered in advance for recognizing the user's voice include recognized words that can be recognized in common regardless of the display screen and recognized words whose recognition is restricted to those displayed on the display screen. Good to be.
In this way, for example, while the convenience of the necessary functions regardless of the display screen is maintained by the commonly recognized recognition words, the possibility of erroneous recognition is reduced by the recognition words whose recognition is restricted. it can.

As a recognition phrase that can be commonly recognized, for example, a recognition phrase commonly used on a plurality of types of display screens may be used.
By doing so, the possibility that functions are restricted depending on the display screen is reduced, and convenience can be maintained. For example, it may be a phrase such as "return" or "cancel" that causes a transition to another display screen. Such a phrase may be, for example, a phrase that needs to be used on any screen.
Recognized words whose recognition is restricted may be, for example, words displayed on a display screen or words to be searched. Such a phrase may be, for example, less necessary to recognize other phrases, and may be more likely to reduce the number of recognized phrases to prevent erroneous recognition.

(4) The recognition words registered in advance for recognizing the user's voice may be those that are displayed on the display screen and those that are not displayed on the display screen.
In this way, for example, even if the user utters a word that is not displayed on the display screen, if the recognition word is a preset recognition word, a certain reaction from the character can be obtained. It can be a surprise for the user and give the joy of finding the user.

It is preferable that voice data output by the character is registered when a voice other than a phrase set in advance as a recognized phrase is input.
In this way, for example, even if it is other than a recognized phrase, there is always a reaction of the character, so that the dialogue is interrupted or an error is reported to the user, so that the user is reminded of the exchange with the system. It is good because you can maintain the feeling of continuing the dialogue with the character.

(5) The state of the function that changes quantitatively may be set to a desired quantitative level directly by voice recognition.
In this way, the desired value can be immediately set to a desired value as compared with, for example, a case where the quantitative level is gradually changed between a small value and a large value. And the time restricted by the operation is reduced.
As the function that changes quantitatively, for example, a volume, a brightness, a scale, and the like may be used. In this way, it is possible to eliminate the need to select buttons such as volume, luminance, and scale to display +-and scales, and to select +-and slide up and down the scales to step up and down.

(6) As recognition phrases registered in advance for recognizing the user's voice, it is preferable that an instruction word corresponding to a function that changes quantitatively and a number indicating a quantitative level be set.
In this way, for example, when the user says an instruction word and a number corresponding to a desired function, the quantitative level of the function can be directly increased or decreased to the level of the number.
For example, as a descriptive word corresponding to a function that changes quantitatively, for example, "onri", "kid", "sukururu", etc., and the numbers are "ichi", "ni", "nikiro" etc. Good. In this way, for example, the input can be performed using the names and numbers of the functions that are intuitive and easy for the user to understand. In particular, for example, the name and the quantitative level may be combined into one recognition word, such as "Onryosan", "Kidoni", "Skelenikiro". In this way, the utterance only needs to be performed once.

Preferably, a button for selecting a function, on which a descriptive word corresponding to the function is displayed, is displayed on the display screen of the display means.
By doing so, for example, the user only has to say the instruction word displayed on the button, so that the user can easily understand.

The display screen of the display means may display a button for selecting a function, the button displaying the value of the current quantitative level of the function.
In this way, for example, the user can check the current quantitative level by looking at the value displayed on the button, and determine whether to increase or decrease to the desired value. .
The value of the current quantitative level may be, for example, a map scale. In this way, for example, if a small scale value is displayed on the button and the user says a larger value, the scale value displayed on the button is also directly changed to that value, and immediately May be able to overlook a wide range of maps. For example, if a large scale value is displayed on a button and the user says a smaller value, the scale value displayed on the button also changes directly to that value, and a detailed map is displayed immediately. May be able to see.

The button for displaying the instruction word corresponding to the function may include a button for executing the function without transitioning to another display screen.
With this configuration, for example, the function can be executed through the dialogue without transiting to another display screen to execute the function, so that the current screen display does not need to be disturbed.

(7) It is preferable to display on the display means whether or not speech recognition is being accepted.
With this configuration, for example, the user may be able to visually recognize whether or not the user can perform a voice operation.

  Whether or not the voice recognition has been accepted may be displayed, for example, by changing the color of the display screen. In this way, for example, the state of voice recognition can be immediately sensed through the user's vision. In particular, for example, when speech recognition is received, the color may be a normal color, and when not, grayscale may be used. In this way, for example, the user can intuitively recognize whether or not speech recognition is being accepted.

(8) Whether or not speech recognition is accepted may be displayed on the display means together with the character.
By doing so, for example, by looking at the character, it is possible to know whether or not the operation by voice is possible, so that the user can easily notice.
As a mode of displaying on the character, for example, a mode in which the state of the character clearly changes may be used. By doing so, for example, the state of voice recognition can be immediately felt. Examples of the manner in which the state of the character clearly changes include, for example, adding an object to the character, changing the color or form of the character, causing a specific pose or gesture, displaying speech in a balloon, and the like. In this way, for example, a user who knows the state of a normal character can immediately notice the change by comparison with the normal state. As a mode of adding an object to the character, for example, equipment related to sound such as a headset, headphones, earphones, and a microphone may be attached to the character. In this way, for example, the user may be associated with voice recognition, which is a function related to sound. As a mode of changing the color or form of the character, for example, it is preferable to change the hairstyle or the color of the hair, or to change into another costume. In this way, for example, the difference from the normal state may be easily understood. In particular, for example, if the character's ears are enlarged, the character may show that he / she is trying to hear the sound well. Further, as a pose or a gesture, for example, even if a gesture of placing a hand behind the ear may be performed, the appearance may indicate that the user is likely to listen to the sound.

(9) While the voice of the character is being output, the voice recognition may be stopped until the output of the voice is completed.
In this way, for example, when a voice is input from the user in the middle of the voice of the character, another process may be prevented from being executed by voice recognition. Other processing may be low urgent processing, such as volume, brightness, scale, and peripheral search. In this way, it is not necessary to execute by voice recognition even if it does not necessarily have to be executed immediately.

It is preferable to receive voice recognition even while the voice of the character is being output.
With this configuration, for example, when a voice is input from the user in the middle of the voice of the character, other processes than the voice recognition need not be interrupted. As another process, for example, a process with a high degree of urgency, such as a process of transmitting position information on a control place to an information collection server, may be used. In this way, the processing that the user wants to execute immediately does not have to be interrupted.

The output of the voice of the character may be stopped when the voice is input from the user while the voice of the character is being output.
In this way, for example, the voice of the user can give an impression that the remark of the character is interrupted. If the output of the voice of the stopped character is not output again, for example, the same utterance does not have to be repeated from the beginning to give an unnatural impression. If the output of the sound of the stopped character is started, for example, from the point where the sound is stopped, it may be possible to give the impression that the character has been waiting during the speech of the user.

When a predetermined input operation is performed while the sound of the character is being output, the sound of the character may be stopped.
In this way, the voice of the character may be stopped by a predetermined input operation, for example, when the third party does not want to hear the conversation with the character. The predetermined input operation may be, for example, an operation of a physical key. With this configuration, it is sufficient to always operate a fixedly existing portion, so that a quick operation can be easily performed.

(10) It is preferable to make a posting for transmitting the position information about the enforcement place to the information collection server in response to the input of the user's voice corresponding to the recognition word registered in advance to recognize the user's voice.
By doing so, for example, a post notifying the control place may be easily and quickly made by voice instead of manual operation.
The enforcement place may be a check place where the execution position and time change, such as an enforcement / checking area, for example. In this way, information on the enforcement place where it is difficult to register the position in advance can be collected by posting.
The position information may be, for example, a current position or a center position coordinate. With this configuration, for example, the control place can be specified by the information that can be obtained reliably and easily, and since the voice recognition is used, the deviation from the actual control position may be small.

(11) It is preferable that a phrase that activates speech recognition and a phrase that starts accepting a post are registered as the predetermined recognition phrase.
By doing so, for example, the user can easily execute the multi-stage operation of voice recognition and post acceptance by speaking a phrase that activates speech recognition and a phrase that starts accepting posts. Is good.

The phrase for activating the speech recognition and the phrase for starting the reception of the post may be registered, for example, as separately separated phrases.
In this way, for example, it may be possible to prevent the reception of the post from being started at the same time as the start of the voice recognition, thereby preventing the occurrence of erroneous recognition. In addition, the phrase that activates speech recognition and the phrase that starts accepting a post may be set as, for example, a series of phrases. In this way, for example, the reception of the post can be started in one shot together with the start of the voice recognition, so that the posting can be immediately made possible.

(12) As the predetermined recognition phrase, a phrase for activating speech recognition and a phrase for posting are preferably registered.
By doing so, for example, the user may be able to easily perform a multi-stage operation of voice recognition and posting by uttering a phrase for activating voice recognition and a word for posting.

The phrase for activating the speech recognition and the phrase for posting may be registered, for example, as separately separated phrases.
By doing so, for example, it may be possible to prevent a message from being posted at the same time as the start of voice recognition and being posted by mistake. The phrase for starting the speech recognition and the phrase for posting may be set as, for example, a series of phrases. In this way, for example, the posting can be performed in one shot at the start of the speech recognition, so that the posting can be performed immediately, and the gap between the control place and the posting place can be minimized.

The predetermined recognition phrase for posting may be shorter than other recognition phrases.
In this way, for example, it is possible to give an instruction in a short time for a highly urgent post.

Predetermined recognition phrases for posting may be more verbose than other recognition phrases.
In this way, for example, when normal speech recognition is used, the possibility of saying another recognized phrase is reduced, and it may be possible to prevent erroneous posting.
The word "redundant" means that, for example, the number of characters is large and the number of characters is divided. In this way, for example, it is possible to reduce the possibility that a user who does not intend to post erroneously utters.

The predetermined recognition phrase for posting may be a phrase that the user is unlikely to say usually.
In this way, for example, it is possible to prevent erroneous recognition from occurring frequently due to words frequently used in the vehicle by the user, and to prevent posting unintended by the user.

The voice of the character in the conversation for posting may be shorter than the voice in other conversations.
By doing so, for example, the posting time can be quickly reduced by shortening the conversation time.

(13) The dialog may be started by input of a voice from a user corresponding to a predetermined recognition phrase.
With this configuration, for example, since the predetermined process is started when a voice is input from the user, the system does not need to be started and the process is not executed.

(14) The dialogue may be started when a voice output from a user corresponding to a predetermined recognition phrase is input to a voice output of a predetermined character.
With this configuration, for example, the output of the voice of the character triggers the user to determine whether or not to start the predetermined process, so that the opportunity to use the system can be increased.
The output of the voice of the character may be, for example, an inquiry as to whether or not a specific process has started. By doing so, for example, the user may be prompted to use the processing.
If the timing of outputting the voice of the character is, for example, regular, the frequency of using the process may be increased. Further, if the timing satisfies a predetermined condition, the user can be encouraged to use the process at a timing suitable for using the process.

(15) The process may be terminated when a predetermined time has elapsed without the input of a voice from the user from the time when the execution of the function required by the passenger of the vehicle is started.
By doing so, for example, an erroneous operation caused by continuing the voice recognition for a long period of time can be prevented.

(16) The character may output a voice prompting the user to input a voice during a period from a point in time when the occupant of the vehicle starts executing a required function until a predetermined time elapses.
In this way, for example, when the user has forgotten to start the process, the user can be prompted to input a voice.

(17) The functions of the system of (1) to (16) may be configured as a program for causing a computer to realize the functions.

  Advantageous Effects of Invention According to the present invention, it is possible to provide a system and a program that provide a user with an interesting operation and driving, do not get tired, and are motivated to use the function positively.

[Basic configuration]
FIG. 1 shows an external view of an embodiment of a navigation device suitable as an electronic device constituting the system of the present invention, FIG. 2 shows a functional block diagram thereof, and FIGS. 13 shows an example of a display mode. As shown in FIG. 1, the navigation device includes a portable device main body 2 which is portable and a cradle 3 which is a mounting member for holding the main body. When the device main body 2 is mounted on the cradle 3, it functions as an on-vehicle navigation device, and when it is detached from the cradle 3, it functions as a portable navigation device (PND). In the present embodiment, the device main body 2 is detachable from the cradle 3 and is installed on a dashboard of a vehicle together with the cradle 3 for use, or the device main body 2 is removed from the cradle 3 and used as a portable (PND). Although it is a type that can be attached to and detached from the cradle 3, it cannot be easily attached to or detached from the cradle 3, and may be a vehicle-mounted fixed type or a portable type. Furthermore, for example, it may be realized by installing (including pre-installed) a predetermined application program in a mobile terminal such as a mobile phone. The application program may be a system for performing navigation itself, or may be a program for accessing a server on which a system for performing navigation is mounted and using the system. The present invention is applicable to such various types of navigation systems.

The pedestal portion 7 is fixed by suction on a dashboard or the like by a suction cup provided on the bottom surface. The pedestal portion 7 and the cradle body 6 are rotatably connected within a predetermined angle range via a connection mechanism such as a ball joint. Since it is a ball joint, the pedestal portion 7 and the cradle body 6 rotate relatively within an arbitrary angle range in the three-dimensional direction, and stay at the arbitrary angle position due to frictional resistance at the joint portion. Therefore, the device main body 2 attached to the cradle main body 6 can also be arranged in an arbitrary posture on the dashboard.

  Further, on one side surface of the case body 4, an SD memory card slot 21 is provided, and the SD memory card 22 on which map data and the like are recorded can be inserted into the SD memory card slot 21. The SD memory card slot 21 includes a memory card reader / writer that reads and writes information from and to the inserted SD memory card 22. A DC jack 10 is provided on the side of the case body 4 where the SD memory card slot 21 is provided. The DC jack 10 is for connecting a cigar plug cord (not shown), and is connected to a cigar socket of a vehicle via the cigar plug cord so that power can be supplied.

  On the other hand, a power switch and a USB terminal 23 are provided on the side opposite to the SD memory card slot 21. By connecting to a personal computer via the USB terminal 23, a software application can be upgraded.

  The following devices and components are arranged inside the case body 4. That is, the microwave receiver 11 is arranged inside the back side of the case body 4. The microwave receiver 11 receives a microwave in a predetermined frequency band, and when receiving a microwave in the set frequency band, detects a signal level of the received microwave. Specifically, the RSSI voltage corresponding to the signal level and the electric field strength is used. The above-mentioned predetermined frequency band is, for example, a frequency band including a frequency of a microwave emitted from the vehicle speed measuring device.

  Further, a GPS receiver 12 that receives a GPS signal and obtains a current position is disposed inside the upper surface of the case body 4. An infrared communication device 14 is arranged inside the front side of the case body 4. The infrared communication device 14 transmits and receives data to and from a communication device having a built-in infrared communication device such as a mobile phone 15. Further, a speaker 20 is also built in the case body 4.

  Further, the device of the present embodiment includes a wireless receiver 13 and a remote control receiver 16. The wireless receiver 13 receives the incoming radio wave of a predetermined frequency. The remote control receiver 16 performs data communication with a remote control (portable device: slave device) 17 and performs various settings for the device. The wireless receiver 13 receives incoming radio waves of a predetermined frequency band. The predetermined frequency may be, for example, a radio frequency band used when the emergency vehicle notifies the base station of the vehicle position.

  The navigation device of the present embodiment is provided with a target notification function as a target notification device for notifying a target such as a vehicle speed measurement device and other traffic monitoring points existing around the vehicle, in addition to the navigation function. The navigation function and the target object notification function are stored in the EEPROM of the control unit 18 as a program to be executed by the computer of the control unit 18, and are realized by the computer of the control unit 18 executing the program.

  That is, the control unit 18 controls the various input devices (the GPS receiver 12, the microwave receiver 11, the wireless receiver 13, the touch panel 8, the infrared communication device 14, the remote control receiver 16, the SD memory card slot 21, A predetermined process is executed based on information input from the USB terminal 23, etc., and output devices (display unit 5, alarm lamp 9, speaker 20, infrared communication device 14, SD memory card slot unit 21, USB terminal 23, etc.) To output predetermined information / alarm / message. This predetermined processing is for executing the above-described functions, and accesses the database 19 and the SD memory card 22 as necessary.

  Here, the database 19 can be realized by a nonvolatile memory (for example, an EEPROM) inside or outside the microcomputer of the control unit 18. In the database 19, information necessary for performing a certain target, a map, and other functions at the time of shipment is registered, and data and the like on the target added later are subjected to predetermined processing. Can be updated via The process for updating may be performed, for example, by mounting the SD memory card 22 storing the additional data in the SD memory card slot 21 and transferring the data from the SD memory card 22 to the database 19. . Further, this data update can be performed by using the infrared communication device 7 or using a personal computer or other external device connected via the USB terminal 23.

  The control unit 18 for realizing the target object notification function operates as follows. That is, when the microwave receiver 11 receives a desired microwave, the control unit 18 outputs a predetermined alarm. Examples of the alarm include a sound output for notifying a buzzer using the speaker 20 or reception of microwaves (detection of a vehicle speed measurement device, etc.), and a message output using characters or images using the display unit 5. .

  Further, when the wireless receiver 13 receives a desired wireless signal, the control unit 18 outputs a predetermined alarm. The warning includes a buzzer using the speaker 20, a sound output for notifying the reception of a microwave (such as an approach of an emergency vehicle), and a message output using characters or images using the display unit 5. It is preferable that the form of the alarm associated with the radio reception and the form of the alarm associated with the microwave reception be different.

  Further, the control unit 18 outputs a predetermined alarm when the current position detected by the GPS receiver 12 and the position of a target such as a traffic monitoring point stored in the database 19 have a predetermined positional relationship. . For this reason, the database 19 stores information on the target object to be detected (position information of the target object including longitude and latitude, type information of the target object, and the like), and information such as a zone where accidents frequently occur and traffic control information. There is traffic safety information for driving, and various information useful for landmarks and driving. Each piece of information is registered in association with the type of specific information (the type of target, the type of traffic control, the zone where accidents frequently occur, the names of landmarks, etc.) and the position information.

  The distance to the target when an alarm is issued can be changed for each type of target. Similar to the above, there are two types of alarms, such as an alarm using a voice using the speaker 20 and an alarm using the display unit 5. FIG. 3 shows an example of an alarm by the display unit 5. In the present embodiment, since the device is a navigation device, since the device has map data as described later, the control unit 18 reads road network information around the current position as a basic screen, and It has a function of displaying a map on the display unit 5. Then, a warning screen 70 is displayed on the display unit 5 so as to overlap the currently displayed screen (here, a map around the current position). FIG. 3 is a display example of a warning screen 70 when the distance between the current position and the LH system, which is a type of speed measuring device, which is one of the traffic monitoring points, when displaying the map 50 is 500 m. Is shown. Further, a process of outputting a warning voice indicating the type of warning and the distance such as “500 m ahead LH system” from the speaker 20 is performed.

  On the other hand, the control unit 18 for implementing the navigation function operates as follows. First, the database 19 stores road network information for navigation. The information for navigation stored in the database 19 may store all information on the whole country at the time of shipment, and the map data etc. provided on the SD memory card 22 for each region may be provided. In this case, the user may prepare an SD memory card 22 in which necessary map data and the like are stored, and mount the SD memory card 22 in the SD memory card slot 21 for use. The map data and the like stored in the SD memory card 22 may be transferred to and stored in the database 19, or the control unit 18 may access the SD memory card 22 and read and use it. good.

  The control unit 18 has a function of reading road network information around the current position from the database 19 and displaying a map around the current position on the display unit 5. The control unit 18 can search a route (route) from one position to another position using the road network information. The database 19 stores a telephone number database in which telephone numbers are associated with location information and names of houses, companies, facilities, and the like of the telephone numbers, and an address and positional information of the addresses in association with each other. It has an address database. The database 19 stores the position information of the traffic monitoring points such as the speed measuring device together with the type.

  Further, the control unit 18 has a function of performing processing of a general navigation device. That is, a map around the current position is displayed on the display unit 5 as needed, and a destination setting button is displayed. The control unit 18 performs a destination setting process when the touch panel 8 detects a touch at a position corresponding to the display position of the destination setting button. In the destination setting process, a destination setting menu is displayed on the display unit 5 to urge the user to select a destination setting method. The destination setting menu has a telephone number search button and an address search button that prompt the user to select a destination setting method. If it is detected that the telephone number search button has been touched, a telephone number input screen is displayed, and position information corresponding to the input telephone number is acquired from the database 19. When it is detected that the address search button has been touched, an address selection input screen is displayed, and position information corresponding to the input address is acquired from the database 19. Then, the obtained position information is set as the position information of the destination, and the recommended route from the current position to the destination is obtained based on the road network information stored in the database 19. As a method of calculating the recommended route, a known method such as the Dijkstra method can be used.

  Then, the control unit 18 displays the calculated recommended route together with the surrounding map. For example, as shown in FIG. 4, a route 53 from the current position 51 to the destination 52 is displayed in a predetermined color (for example, red) as a recommended route. This is similar to a general navigation system. In the present embodiment, the control unit 18 compares the position information on the route 53 with the position information of a target such as a traffic monitoring point stored in the database 19, and determines the position of the traffic monitoring point or the like located on the route 53. Show location. It should be noted that information provision for driving the route 53 with safe driving may be limited to a traffic monitoring point among various targets stored in the database 19.

  Thereby, for example, as shown in FIG. 4, the balloon is displayed from a position on the road, and the type of the traffic monitoring point at that position stored in the database 19 is displayed in the balloon. For example, FIG. 4A is a display example of a warning point search screen, and shows an example in which traffic monitoring points 55a to 55f are displayed. The traffic monitoring point 55a displays a letter “N” indicating the N system in a balloon. The traffic monitoring points 55b, 55c, and 55e display characters "LH" indicating the LH system in balloons. The traffic monitoring point 55d displays "loop" indicating a loop coil in a balloon. The traffic monitoring point 55f displays a letter “H” indicating the H system in a balloon. As described above, when the touch panel 8 detects a touch on the balloon position in the simplified display state in which characters are displayed in the balloon, the simple display is switched to the detailed display as shown in FIG. In the detailed display, the warning screen shown in FIG. 3 is displayed in a balloon.

  As shown in FIG. 4A, a traffic monitoring point type specifying unit 56 is displayed on the lower right side of the display unit 5. The traffic monitoring point type designation unit 56 is a part that displays a button listing the types of the traffic monitoring points existing on the route 53. In the example of FIG. 4A, an “N” type button 57a indicating the N system of the traffic monitoring point 55a, an “LH” type button 57b indicating the LH system of the traffic monitoring points 55b, 55c, 55e, and a traffic The "loop" type button 57c indicating the loop coil of the monitoring point 55d and the "H" type button 57d indicating the H system of the traffic monitoring point 55f are displayed. When detecting the touch of the type button on the display unit from the touch panel 8, the control unit 18 reversely displays the touched type button and changes the display mode of the traffic monitoring point corresponding to the touched type button in a simple manner. If it is being displayed, the display is switched to the detailed display, and if it is being displayed, the display is switched to the simple display.

  The car navigation device according to the present embodiment has a peripheral search function as a method for setting a destination (hereinafter, a transit point is also included). When the peripheral search function is selected and activated, the control unit 18 extracts a facility that matches the designated condition and is close to the current position, and draws the extraction result on the display unit 5. Then, the user can select one of the candidates drawn on the display unit 5 and specify it as a destination (including a stopover) by confirming.

  That is, in order to realize such a function, the database 19 of the present embodiment stores information on each facility together with information on the classification of the facility together with its position information. The information on the classification of the facility is a plurality of types of items summarized by the name of the genre to which each facility matches.

  In the present embodiment, when any item is specified, the control unit 18 extracts a facility that matches the specified item and is close to the current position, and uses the extraction result as a destination candidate. Drawing is performed on the display unit 5. The user can designate any of the candidates drawn on the display unit 5 as a destination by selecting one of the candidates.

  When any one of the items is selected, the control unit 18 accesses the database 19 and determines that the facility is located within a reference distance (for example, 10 km) around the current position and matches the classification of the specified item. Extract what you want to do. Then, a predetermined number (for example, 10) of closest facilities are drawn with corresponding icons (marks) indicating the facilities on corresponding locations on the map drawn on the display unit 5. As the facility information stored in the database 19, each icon is registered in association with each facility, and at the time of drawing, the related icon is read out and drawn at a predetermined position on the display unit 5.

  If the current position is present on the map drawn on the display unit 5, the own vehicle icon indicating the own vehicle is drawn in a position corresponding to the current position. Further, when drawing such an icon of the facility, a number is added and displayed in order from the closest to the own vehicle. The number is updated at any time as the vehicle moves.

  Then, when the user selects a desired facility, the control unit 18 that recognizes the desired facility obtains a recommended route with the facility as a destination, and draws the result over the map on the display unit 5.

  Further, the control unit 18 has a function of providing route guidance to the set destination. In other words, the control unit 18 draws map information representing a road or the like on the display unit 5 while sequentially detecting the own vehicle position by GPS or autonomous navigation in accordance with the selection of the guidance start by the user, and Provides directions using images and sounds.

  Instruction input such as designation and selection by the user is performed by touching a button on which a name of an item or function is displayed on the display unit 5, an icon of a facility, selecting by a remote control operation, or inputting a predetermined voice. This can be performed with the detection of the control unit 18 as an opportunity.

[Interaction with character]
《Basic of interactive function》
Hereinafter, the interactive function with the character, which is a feature of the present embodiment, will be described. This interactive function is a function realized by the control unit 18 executing a program, and recognizes recognition information based on the result of recognizing the voice of the user who is the occupant of the vehicle and recognizes that the user's voice has been recognized. This is a function realized by outputting a voice of a predetermined character shown.

  In order to execute this interactive function, the database 19 stores a recognition word (recognition phrase) and a response phrase which is voice data of the character corresponding to the recognition word. The control unit 18 recognizes the user's voice input via the microphone 20 based on the recognition word. That is, the control unit 18 recognizes the voice uttered by the user as a phrase based on the voice signal of the user, and determines whether the recognized phrase matches the recognized word. Then, the control unit 18 causes the speaker 20 to output a response phrase corresponding to the recognized word determined to match the recognized phrase. By preparing various combinations of the recognition word for the dialogue and the response phrase that is the voice of the character, it is possible to cope with various processes executed according to the dialogue, as described later.

  This allows the user to have a simple conversation with the character using the electronic device as a system. The character of the present embodiment is set, for example, as a girl named “Ray”. Various functions such as the above-described peripheral search can also be performed by interacting with the character. The database 19 stores “letan” as a recognition name as a character name.

  The database 19 stores character image (including still images and moving images) data. The control unit 18 can display a still image and a moving image of the character on the display unit 5 based on the image data. In addition, the control unit 18 uses a lip link that moves the mouth and body of the character displayed on the display unit 5 so that a part of the response phrase matches the response phrase to be output. You can feel it.

  Further, as the voice and image of the character stored in the database 19, a plurality of modes (modes) are set for the same person. For example, the database 19 stores one response phrase and image data in three modes, “standard ray”, “reformed ray”, and “chibi ray”, while being a single person “ray”. are doing. "Standard ray" is the basic mode of the character. “Ray after transformation” is a mode in which clothing and hairstyle are changed from “standard ray”. "Chibi Rei" is a child-like mode that changes your head and body. The control unit 18 outputs the voice and image of the character according to the selection of any one of the modes by the user.

《Recognition word》
FIGS. 5 and 6 are examples of recognition word lists stored in the database 19. Each column of the recognition word list is assigned a list number. In each column, as described later, each display screen M1, V1, V1a, S1, S1a, S2, S2a, S2_list, S2a_list, R1, R1a, R1b, A1, A2, A3 displayed on the display unit 5 is described. , Each includes a recognizable recognition word.

  In list number 1, a startup word for activating voice recognition, "Retann, Boyskontororu" is registered. When recognizing the activation word, the control unit 18 activates a voice recognition function for executing various functions such as a peripheral search. Therefore, in the initial state, the control unit 19 is on standby in a state where only the activation word can be recognized by voice. The list number 1 corresponds to a display screen M1 described later.

  In list number 2, a recognition word for starting any one of the peripheral search, the scale change, the volume change, and the brightness change after the voice recognition is activated is registered. For example, “Shuhen” is registered as a recognition word for starting a peripheral search. As a recognition word for starting the scale change, "Skjl" is registered. As the recognition word for starting the volume change, “Onryo” is registered. “KIDO” is registered as a recognition word for starting the luminance change. The list number 2 corresponds to a display screen V1 described later. Further, in the list number 2, a recognition word "Jitakaku" for searching for a route to home with one utterance when returning to home is registered. As described above, since the recognition word corresponding to the function frequently used by the user is registered as the recognition word when the voice recognition is activated, the voice recognition can be started and immediately executed.

  In list number 3, recognition words corresponding to functions to be executed after the start of route guidance are registered. For example, in addition to the recognition word of list number 2, recognition words for canceling route guidance such as "Annu Chu", "Anni Shishi", and "Anni Quit" are registered. In this way, by preparing a plurality of types of recognition words for executing the same function of canceling the route guidance, the possibility of being unable to recognize even if the user's utterance contents are slightly different is reduced. it can. The list number 3 corresponds to a display screen V1a described later. In particular, as shown below, “Shihen”, “Onryou”, and “Kid” are instruction words displayed on the buttons of the display screens V1 and V1a. Therefore, the user can input an instruction by speaking the displayed instruction word.

  In list numbers 4 and 5, recognition words for designating a genre in the peripheral search are registered. The genre recognition word is displayed in hiragana characters on a button of an item for specifying a genre. In the screen display in which the recognition word buttons belonging to list number 4 are displayed, the recognizable genres are limited to the recognition words belonging to list number 4. The list number 4 corresponds to a display screen S1 described later. In addition, there are multiple types of recognition words that specify the same genre, such as "Familys" and "Family Restaurant" for family restaurants, and "Kaden" and "Denkiya" for electronics stores. By doing so, it is possible to reduce the possibility that recognition will not be possible even if the user's utterance content is slightly different

  In the screen display in which the recognition word buttons belonging to list number 5 are displayed, the recognizable genres are limited to the recognition words belonging to list number 5. The list number 5 corresponds to a display screen S1a described later. In this manner, the genre that can be recognized on each display screen is limited to the recognition word corresponding to the button of the item displayed on each display screen, so that the possibility of erroneous recognition is reduced.

  Further, in the list number 4, the recognition words "nyanji" and "next" for transitioning to the display screen S1a of the list number 5 are registered. In the list number 5, the recognition words "ichi-ji" and "mae" for transitioning to the display screen S1 of the list number 4 are registered. In this way, by preparing a plurality of types of recognition words for executing the same function of shifting the display screen of the genre, there is a possibility that even if the utterance contents of the user are slightly different, recognition cannot be performed. Can be reduced.

  In list numbers 6, 7, 8, and 9, registered recognition words for selecting the facilities searched by the peripheral search are registered. On the display screens corresponding to the list numbers 6 and 7, the facilities searched by the peripheral search are displayed at the locations on the map by icons numbered in order from the closest to the current position. As the recognition word, a name of a number for selecting a facility is registered. For example, recognition words indicating numbers are registered, such as "ichi", "ichiban", "ni", "niban". In this way, by preparing a plurality of types of recognition words for selecting the same target as the destination, it is possible to reduce the possibility that recognition may not be possible even if the utterance contents of the user are slightly different. In the display screens corresponding to the list numbers 6 and 7, all of the searched facilities (in this example, 10 places) can be selected by voice irrespective of whether they are displayed on the screen.

  In list numbers 6 and 7, recognition words for changing the scale of the displayed map are registered. That is, in list number 6, the recognition word "sukeru" for accepting the start of the scale change is registered. The list number 6 corresponds to a display screen S2 described later. In list number 7, in addition to the recognition word "scale" for accepting the start of the scale change, a recognition word for changing the scale is registered. This list number 7 corresponds to a display screen S2a described later.

  The recognition words for changing the scale include a recognition word for enlarging the map scale for detailed display, a recognition word for reducing the map scale for wide-area display, and a recognition word for indicating the scale number and unit. Is included. Recognition words that increase the scale of the map are `` hide '' and `` shosai ''. Recognition words that reduce the scale of the map are `` shuffle '' and `` koiki ''. A recognition word to be changed is included. The term "gradual" means that a scale of a plurality of levels is set in advance, and the levels are raised or lowered one by one. In this way, by preparing a plurality of types of recognition words for executing the same function of changing the scale stepwise, even if the contents of the user's utterances are slightly different, recognition may not be possible. Performance can be reduced. In particular, when raising or lowering the scale, words used everyday are used as recognition words, so that the user does not have to be confused by words instructing a change in volume.

  In addition, the recognition words that change the scale include recognition words that can specify the scale number and unit, such as "Ju-Me-Toru", "Ju-go-Me-Toru", and "Go-J-Me-Toru". It is. Thus, when the user utters and specifies the recognition word of the desired scale, the control unit 18 that recognizes the recognition word directly changes the scale to the specified map scale. Further, in the list numbers 6 and 7, registered recognition words "list" and "list and hyouji" to be displayed on a list display screen of a list number 8 described later are registered. In this way, by preparing a plurality of types of recognition words for performing the same function of transitioning to the screen of the list display, there is a possibility that even if the utterance contents of the user are slightly different, recognition cannot be performed. Can be reduced.

  On the display screens corresponding to the list numbers 8 and 9, the facilities searched by the peripheral search are displayed in a list by a button displaying the number. The names of the numbers for selecting the facilities displayed in the list are registered as recognition words. The list number 8 corresponds to a display screen S2_list described later, and the list number 9 corresponds to a display screen S2a_list described later. The names of the registered numbers are the same as those in the list numbers 8 and 9 described above. However, in the list numbers 8 and 9, the selectable facilities are limited to those displayed on the display screen. In this example, the first to fifth facilities can be selected on the display screen S2_list corresponding to the list number 8, and the sixth to tenth facilities can be selected on the list number S2_list.

  Further, in list numbers 8 and 9, recognition words "list" and "list release" for canceling the list display are registered. In this way, by preparing a plurality of types of recognition words for executing the same function of canceling the list display, it is possible to reduce the possibility that recognition may not be possible even if the utterance contents of the user are slightly different. . Further, similarly to the list numbers 4 and 5, in the list number 8, the recognition words "niji" and "next" for transitioning to the display screen S1a of the list number 9 are registered. Further, in the list number 9, recognition words “ichipage” and “mae” for transitioning to the display screen S1 of the list number 8 are registered.

  In the list numbers 10, 11, and 12, registered are the recognition words "Ankai Kaishi", "Annai Hiyoshi", and "Annanashi", which indicate the start of the searched route guidance. In this way, by preparing a plurality of types of recognition words for instructing the same function of route guidance, it is possible to reduce the possibility that recognition cannot be performed even if the utterance contents of the user are slightly different. In particular, in addition to the command tone of "Annai Kaishi", the tone of the request with the familiarity of "Annai Greeting" and "Annaishite" is also prepared, so that the tone can be adjusted according to the familiarity with the character You can enjoy changing.

  The list number 10 corresponds to a display screen that displays the searched route after the route search. This display screen corresponds to a display screen R1 described later. The list number 11 corresponds to a display screen for changing the scale of the map while displaying the searched route. This display screen corresponds to a display screen R1a described later. The list number 12 corresponds to a display screen for changing a route condition while displaying the searched route. This display screen corresponds to a display screen R1b described later.

  The list numbers 10, 11, and 12 include a recognition word "Sukeru" for starting a scale change, a recognition word "Shuhen" for re-searching surrounding facilities, and a recognition word "Joken" for starting a change in route conditions. "And" Routing Joken "are registered. In this way, by preparing a plurality of types of recognition words for instructing the same function of changing the route condition, it is possible to reduce the possibility that recognition may not be possible even if the user's utterance contents are slightly different. .

  Further, in the list number 11, similarly to the list number 7, a recognition word for changing the scale is registered. In the list number 12, a recognition word for changing the route condition is registered. The route condition is a search condition for giving priority to a route search. As the route conditions in this embodiment, expressway priority, general road priority, and recommended route are set. The recommended route is a condition set by default, for example, priority is given to the required time to the destination, and priority is given to the distance to the destination. Corresponding to this, in the list number 12, "Suisho", "Ippando", and "Sokodo" are registered.

  Recognition words for changing various functions of the present embodiment are registered in the list numbers 13, 14, and 15. In list number 13, recognition words for changing the map scale are registered in the same manner as described above. The list number 13 corresponds to a display screen A1 described later.

  In the list number 14, a recognition word for changing the volume is registered. The list number 14 corresponds to a display screen A2 described later. The recognition words for changing the volume include a recognition word for increasing the volume, a recognition word for decreasing the volume, and a recognition word indicating the level of the volume.

  Recognition words that increase the volume include recognition words that gradually change the volume, such as “app” and “large”, and recognition words that reduce the volume include “daun” and “small”. The term “gradual” means that a plurality of levels of volume are set in advance, and the levels are raised or lowered one by one. In this way, by preparing a plurality of types of recognition words for executing the same function of gradually changing the volume, even if the contents of the user's utterance are slightly different, recognition may not be possible. Performance can be reduced. In particular, when raising or lowering the volume, words used everyday are used as recognition words, so that the user does not have to be confused by the words instructing to change the volume.

  The recognition word for changing the volume includes a recognition word such as "zero", "ichi", or "ni", which can designate a numeral indicating the volume level. Thus, when the user utters and specifies the level of the desired volume, the control unit 18 that recognizes the utterance directly changes the volume to the specified level. “Zero” is a recognition word that realizes a function of setting the volume to zero, that is, a function of muting the sound output from the speaker 20. Thus, when the user does not want to hear the voice of the character to others, it is possible to prevent the voice of the character from being immediately heard only by uttering the recognition word for setting the volume to zero.

  In list number 15, a recognition word for changing the luminance is registered. The list number 15 corresponds to a display screen A3 described later. The recognition words for changing the luminance include a recognition word for increasing the luminance, a recognition word for decreasing the luminance, and a recognition word indicating the level of the luminance.

  Recognition words for increasing luminance include recognition words for gradually changing luminance, such as "appi" and "akaruku", and recognition words for decreasing luminance such as "daun" and "easily". The term “gradual” means that a plurality of levels of luminance are set in advance, and the levels are raised or lowered one by one. In this way, by preparing a plurality of types of recognition words for executing the same function of changing the luminance stepwise, even if the utterance contents of the user are slightly different, recognition may not be possible. Performance can be reduced. In particular, when raising or lowering the brightness, words used everyday are used as recognition words, so that the user does not have to be confused by words instructing a change in brightness.

  The recognition words for changing the brightness include recognition words such as “zero”, “ichi”, and “ni”, which can designate a number indicating the brightness level. As a result, when the user speaks the desired luminance level, the control unit 18 that recognizes this directly changes the luminance to the designated level. “Zero” is a recognition word that realizes a function of setting the luminance to zero and a function of making the screen of the display unit 5 invisible so that the display contents cannot be seen. Thus, when the user does not want to see the image of the character by others, the user can immediately hide the image of the character simply by uttering the recognition word for setting the brightness to zero.

  In the above list numbers 13, 14, and 15, recognition words for executing various functions are registered in common. That is, “scale” related to the scale change, “smart” related to the peripheral search, “onryou” related to the volume change, and “kid” related to the brightness change are registered.

  When the user utters “OK” on the display screen of the list number 13, the control unit 18, which recognizes this, completes the setting of the changed scale. On the other hand, when the user utters “Scure” on the display screens of the list numbers 14 and 15, the control unit 18 recognizing this makes a transition to a display screen for scale change, that is, a display screen corresponding to the list number 13. .

  When the user utters "Onryo" on the display screen of the list number 14, the control unit 18 recognizing the utterance completes the setting of the changed volume. On the other hand, when the user utters “OnRyo” on the display screens of the list numbers 13 and 15, the control unit 18 recognizing the utterance changes the display screen to the volume change display screen, that is, the display screen corresponding to the list number 14.

  When the user utters “KIDO” on the display screen of the list number 15, the control unit 18 recognizing the utterance completes the setting of the changed luminance. On the other hand, when the user utters “KIDO” on the display screens of the list numbers 13 and 14, the control unit 18 recognizing the utterance makes a transition to a display screen for changing the brightness, that is, a display screen corresponding to the list number 15.

  As described above, by changing the function according to the display screen even for the same recognition word, the user does not need to remember different recognition words in order to execute related but different functions.

  Furthermore, in the list numbers 13, 14, and 15, a recognition word "Jitakaku" for searching for a route to home with one utterance when returning to home is registered. As described above, since the recognition word corresponding to the function frequently used by the user is registered as the recognition word when the voice recognition is activated, the voice recognition can be started and immediately executed.

  In each of the list numbers 1 to 15, recognition words that can be recognized in common on a plurality of display screens and that execute various functions are registered. First, recognition phrases "return", "take out", and "redo" are registered as phrases to return to the previous process. In addition, as the release phrase for releasing the function or the process, the recognition words “ONSAIKAIJO”, “SHIRYU”, and “GENZAICHI” are registered. “Onseikai” is a recognition word for canceling voice recognition. “SURU” is a recognition word for terminating the current process. “Genzaichi” is a recognition word that causes a transition to the current position display. These are recognition words that can be commonly recognized on all display screens after the voice recognition is activated. By issuing this common recognition word, the user can always restart the process, return to the initial state, and the like.

  Further, in the list number 16, a recognition word for recognizing the user's utterance of Yes (affirmation) and No (negation) is registered. This recognition word is used for recognizing the user's mere utterance of Yes or No in response to a question from the character. Such a recognition word can be commonly recognized on all screens. “OK”, “OK”, “YES”, “YES”, and “UN” are registered as recognition words of Yes. “No”, “stop”, “no”, “no”, “no”, “do not go”, and “noisy” are registered as recognition words of No. In this way, by preparing a plurality of types of recognition words for recognizing the user's Yes and No, it is possible to reduce the possibility that the recognition cannot be performed even if the utterance contents of the user are slightly different. In particular, the expressions of Yes and No change depending on the other party, but the user can reply Yes and No according to the tone of the character.

  As described later, some of the above recognition words are displayed as characters on the display screen, and some are not displayed on the display screen. What is displayed in characters is good because the user can visually confirm what should be uttered in order for the control unit 18 to execute the function.

《Response phrase》
7 to 21 illustrate a part of a list of response phrases to be output as the voice of the character by the control unit 18 according to the recognition result of the recognition word. The database 19 stores a list of such response phrases and audio data. The upper column of the columns shaded in the list is the number of the response phrase. The lower column shows the content of the process executed by the control unit 18 according to the recognition word spoken by the user. “Letan, Boys Contour” in the margin is a start word registered in the list number 1 of the recognition word.

  As the response phrase, one or more phrases are registered for each process executed by the control unit 18. FIG. 7 is an excerpt of a list of response phrases for “standard ray”. The first column from the left in FIG. 7 is a plurality of response phrases when the user speaks the activation word “Retan, Boys Contorol” and the control unit 18 starts speech recognition. The second column is a response phrase when the control unit 18 lowers the volume. The third column is a response phrase when the user selects the eighth facility and the control unit 18 changes the destination to the eighth. The fourth column is a response phrase when the control unit 18 stops guiding. The fifth column is a response phrase when the control unit 18 changes the volume or luminance level to 3.

  Such a list of response phrases is set for each of the three aspects of the character, that is, “standard ray”, “reformed ray”, and “chibi ray”. The response phrases in the list are different according to the three aspects. FIG. 8A is a list of response phrases at the start of voice recognition of “Ray after transformation”. The response phrase of "Relay after transformation" is compared with the response phrase of "Standard ray", such as "Do you have any errands?", "Start speech recognition. Speak slowly and clearly." And a more polite tone is set. FIG. 8B is a list of response phrases at the start of voice recognition for “Chibi Ray”. The response phrase of "Chibi-Ray" is set to a more relaxed tone, such as "Lay-tan, voice control started." I have. FIGS. 9A to 9I are extracts of response phrases in response to a user's utterance. These specific response phrases will be described in a processing example described later. As the user's dialogue, for example, if the meaning of the user's utterance and the voice of the character are established as an utterance and a response to the utterance, a feeling of mutual communication can be obtained. Even if the utterance and the meaning of the utterance are irrelevant, the user feels interesting and unexpected. Even if the utterance and the answer to it are valid as semantic content, and the case where the semantic content to the utterance is inappropriate, it is possible to produce imperfectness similar to a real conversation, It can make you feel human.

  In such a list, one or more response phrases are registered in the same processing column. The control unit 18 randomly outputs a response phrase corresponding to the same process from among those registered in each column. However, the control unit 18 selects at random from those except the previously output response phrase so that only the same phrase is not repeatedly output. In particular, as shown in FIG. 7, a large number of response phrases in the case of frequently used processing such as the start of voice recognition are prepared, and the control unit 18 outputs them randomly.

An operation example of the control unit 18 is as follows.
1. When there are five phrases, A, B, C, D, and E, first, the phrase is randomly selected from the five phrases.
2. If B is selected first, the next time, A, C, D, and E are selected from four.
3. Next, when E is selected, next time, A, C, and D are selected from among the three.
4. When all the selections have been completed, the next time, the process returns to the beginning, and randomly selected from five of A, B, C, D, and E.
In the present embodiment, processing for executing various functions as described below is performed as predetermined processing for outputting information desired by the user in response to the dialogue. If the process according to the dialogue is a process of outputting information as a result of the dialogue, the user is motivated to interact with the character to execute the function. If the process corresponding to the dialogue is a process of outputting information during the dialogue, the willingness to proceed with the dialogue by sequentially uttering in order to execute the function increases. If the process according to the dialogue is a process of outputting a response phrase that constitutes the dialogue, the user wants to hear the voice of the character and interacts, so the user can enjoy the dialogue itself.

《Peripheral search processing》
The control unit 18 executes various processes in accordance with speech recognition for recognizing a speech uttered by the user based on the recognition word as described above and a dialogue for outputting a voice of the character based on a response phrase. First, a description will be given of a peripheral search process according to such a dialogue.

  The peripheral search is a process in which target information can be obtained by sequentially narrowing down from a plurality of candidates through a plurality of selections, and includes a genre selection, facility selection, and route selection phase. Such information is information that a passenger of the vehicle wants to know, particularly information that a driver of the vehicle wants to know.

  Hereinafter, an example of the peripheral search processing will be described with reference to FIGS. 10 to 21 are explanatory diagrams showing an example of a display screen in each phase on the left and examples of the corresponding recognition word and response phrase on the right. Each display screen M1 (including M1a), V1, V1a, S1, S1a, S2, S2a, S2_list, S2a_list, R1, R1a, R1b, A1 (including A1a), A2 (including A2a), A3 (including A3a) Includes the recognition word list numbers 1 to 15 (FIGS. 5 and 6) as described above.

  The description shown on the left of the display screen examples of FIGS. 10 to 21 is “recognized word recognized as user's voice → response phrase of character output in response to this → display screen to be changed by this”. Is shown.

  The control unit 18 displays these display screens on the display unit 5 by drawing screen configuration data such as buttons, icons, texts, and maps stored in the database 19 in a memory. Further, as described above, the control unit 18 can perform the neighborhood search, the route search, and the route guidance.

(Waiting for voice recognition activation)
First, the control unit 18 is in a state where only the activation word can be recognized when waiting for voice recognition activation for predetermined processing such as a peripheral search. The display screen M1 in FIG. 10 is an example of a screen waiting for voice recognition activation. On the display screen M1, an icon indicating the current position 51 is displayed together with a map around the current position 51. At the upper left of the display screen M1, the current time (10:00) is displayed, and below it, a scale button B1 indicating the current quantitative level of the map scale and the unit (100m), and a voice recognition button. A voice recognition button B2 on which an instruction to be activated (voice recognition) is displayed is displayed. On the lower right of the display screen M1, the upper body of the character 100 is displayed. The character 100 is a standard ray, and its display position is a position that does not block the display of various buttons, the current position, the current time, and the like.

  In this state of waiting for voice recognition activation, predetermined processing such as peripheral search cannot be performed by voice recognition. For this reason, the user who wants to change the map scale makes a selection by touching the scale button B1. When the scale button B1 is selected in this way, the control unit 18 displays a + button B1a and a − button B1b to the right of the scale button B1, as shown in the display screen M1a of FIG. The user makes a selection by touching the + button B1a to increase the scale and touching the-button B1b to decrease the scale. In response, the control unit 18 changes the scale of the displayed map stepwise.

  When the user utters "Retan, Boys Contoroll" in the state of waiting for the voice recognition activation, the control unit 18 outputs the corresponding response phrase and activates the voice recognition. I do. As a result, for example, the speaker 20 outputs a voice saying “What is your business?”. Then, the control unit 18 causes the display screen M1 to transition to the display screen V1 shown in FIG.

  Note that, even when the user touches and selects the voice recognition button B2, the control unit 18 outputs the response phrase as described above and activates voice recognition. The control unit 18 displays the buttons corresponding to the functions that can be selected by manual operation or voice input on the display unit 5 in different colors from the other buttons. For example, on the display screen of this embodiment, buttons that can be selected by voice input are displayed in blue, and other buttons are displayed in black. Thus, the user can visually recognize the function that can be input by voice. Note that whether or not the same function can be selected by voice input differs depending on the display screen. For example, in the display screens M1 and M1a of FIG. 10, since the voice recognition function has not started, the scale button B1 is in a state where it cannot be selected by voice input and is displayed in black. Then, after the voice recognition function is started as described later, the scale button B1 is displayed in blue because it can be selected by voice input.

(Start speech recognition)
A display screen V1 in FIG. 11 is an example of a screen for starting voice recognition in a navigation (navigation) standby state. Note that the display screen V1a in FIG. 12 is an example of a screen for starting speech recognition after the start of navigation guidance described later. When the voice recognition is activated, the control unit 18 displays a map scale button on the display screen V1 in blue indicating that voice input is possible. The control unit 18 causes the display screen V1 to display buttons of other functions that allow voice input in blue, which indicates that voice input is possible. Among these buttons, the voice release button B2x is a button on which the instruction word “voice release” to end voice recognition is displayed. The peripheral button B3 is a button on which the instruction word "periphery" for starting the peripheral search is displayed. Since the peripheral search cannot be performed during the navigation guidance, the control unit 18 does not display the peripheral button B3 on the display screen V1a in FIG. The control unit 18 displays a guidance stop button B4x on which the instruction word "stop guidance" for stopping guidance is displayed at the same position as the peripheral button B3 of V1 on the display screen V1a.

  Further, on the display screens V1 and V1a, a volume button B5 and a brightness button B6 are displayed in the same row as the scale button B1, the audio release button B2x, and the guidance stop button B4x. The volume button B5 is a button on which an instruction word "volume" for starting a volume change and a numeral "5" indicating the current quantitative level of the sound are displayed. The luminance button B6 is a button on which an instruction word “luminance” for starting a luminance change and a numeral “5” indicating a current quantitative level of luminance are displayed. Further, a home button B7 is displayed on the upper right of the display screen V1. The home button B7 is a button on which the instruction word "home" for performing route guidance with the home as the destination is displayed. These descriptive words and numbers indicating quantitative levels are words registered as recognition words, as shown in FIGS.

  As described above, the display area of the item constituted by the plurality of buttons has a portion where the map, which is the image behind, is visible. That is, there is a gap between the buttons, and the map behind can be seen. On the other hand, the display area of the character 100 is larger than one button, and does not have a portion that can be seen behind in a portion overlapping the map. Note that, in a gap generated between the hair and the body or between the limb and the body, there may be a portion where a map behind can be seen. However, such a portion is excluded as a display area of the character 100.

  The position of the character 100 displayed on the display unit 5 by the control unit 18 is a position that does not obstruct the visual recognition of the current position and the guide route. In the display screen V1 of FIG. 11 and the display screen V1a of FIG. 12, the character 100 is displayed at a position closer to the lower right on the screen. It is displayed at the position where you approached, at the upper left or upper right.

(Select genre)
When the user utters “Shihen” on the display screen V1 during the standby of the navigation, the control unit 18 changes the display screen V1 to the display screen S1 of the periphery 1 shown in FIG. Hey, where are you going? " As described above, in the peripheral search in which the process is performed by performing the selection a plurality of times, the character 100 makes an utterance that prompts the next selection of the genre selection, so that the user can immediately know what to do next. Good. On the other hand, on the display screen of V1a during navigation guidance, the peripheral search function does not work. For this reason, even if the user utters “Shihen”, the control unit 18 recognizing the utterance outputs the voice of the character “What did you say?” Do not transition. As described above, when a process that cannot be performed next is selected, the character 100 speaks a response phrase corresponding to the selected process, thereby indicating that the user cannot perform the process on the display screen. Good.

  As described above, the control unit 18 inputs the voice for activating the voice recognition from the user → outputs the response phrase of the character inquiring about the business in response to the input → inputs the voice for starting the function in response to the user The processing proceeds based on a dialogue in which at least one round trip is performed. The output of the response phrase in this dialogue has the function of indicating that the character has recognized the user's voice, together with the meaning of the response phrase.

  As described above, the control unit 18 displays the genre button B8 on which the genre name as the recognition word is displayed on the display screen S1 in FIG. 13 to which the transition is made by the utterance of the user. The genre names displayed on these genre buttons B8 correspond to the recognition words of list number 4 in FIG. The genre button B8 can also be selected by the user by touching. Since the genre name does not include kanji and is in hiragana or katakana, it is easy to visually recognize what the driver or the like should speak.

  When the user utters the recognition word "Famiresu" displayed on the button on the display screen S1, the control unit 18 causes the character to output a voice saying the response phrase "Does the family go alone?" Then, the control unit 18 proceeds to a process of searching for a family restaurant candidate. Therefore, there is no need for the user to make any further selection in the genre selection phase. In other words, "Does family go alone?" May be a voice that informs the user that the next genre selection is not necessary. In addition, this response phrase can be used to make the user aware that he / she is alone, except for the character 100 who is the talking partner, and to increase the intimacy with the character 100.

  In addition, in the case where the user wants to select a genre other than the genre displayed on the display screen S1, the control unit 18 displays a page button displaying the recognition word “2 pages” for transitioning to the next page on the display screen S1. B9 is displayed. In this display screen S1, when the user speaks "niji" or "next", the control unit 18 transitions the screen displayed on the display unit 5 to the display screen S1a of the periphery 2 in FIG.

  On the display screen S1a, a genre button B8 displaying a genre name corresponding to the recognition word of the list number 5 in FIG. 5 is displayed. When the user utters the recognition word of the genre name displayed on the genre button B8, the control unit 18 outputs a response phrase corresponding thereto. Further, the control unit 18 displays on the display screen S1a a page button B9 displaying a recognition word "1 page" for transitioning to the previous page. In this display screen S1a, when the user utters “Ipuji” or “Mae”, the control unit 18 transitions the screen displayed on the display unit 5 to the display screen S1 of the periphery 1 in FIG.

(Facility selection)
As described above, when the genre is selected, the control unit 18 searches for facilities around the current location belonging to the genre, and displays a screen displayed on the display unit 5 as shown in FIG. Transit to S2. The display screen S2 displays the result of the facility search. That is, on the display screen S2, the facilities that have been hit by the search are displayed as icons C1 with numbers assigned to locations on the map in the order from the current location. In FIG. 15, an icon C1 in which numbers 1 to 5 are displayed in a circle is displayed at a position on the map. In this way, the result of the peripheral search displays only the facilities of the target (genre) necessary for the user. At this time, by displaying the map in gray scale and displaying the icon C1 in color, the location and number of the facility can be more easily understood. In addition, when the screen transits from another screen to the screen of S2, the control unit 18 outputs a response phrase that prompts the user to select a destination, such as “Where are you going?”.

  The user selects a facility on the display screen S2 with the content corresponding to the display of the icon C1. That is, when the number displayed on the icon C1 of the desired facility is spoken, the control unit 18 outputs a response phrase corresponding to the number and searches for a route to the facility. For example, when "Ichi" or "Ichiban" is uttered, the character 100 utters "No. 1", and a route search to the facility indicated by No. 1 is executed. As described above, the character 100 speaks the number spoken by the user, so that the user can confirm the instruction content of the user.

  Note that a scale button B1 and a list button B10 are displayed on the display screen S2. The scale button B1 is a button for changing the map scale as described above. On the display screen S2, when the user who wants to change the scale of the map utters "Sukeru", the control unit 18 outputs a response phrase urging the user to change the scale, and the facility selection 2 shown in FIG. To the display screen S2a. For example, when the user utters “OK”, the control unit 18 outputs a response phrase “Instruct something”, and as shown in FIG. 16, + buttons B1a,-for changing the scale. The button B1b is displayed. The scale change processing by voice input will be described later.

  The list button B10 is a button for changing the screen for selecting the facility from the icon display to the list display. On the display screen S2, when the user speaks “list” or “list”, the control unit 18 shifts the screen displayed on the display unit 5 to the display screen S2_list of the facility selection 1 shown in FIG. Let it. On the display screen of this S2_list, the searched facilities are displayed not as icons but as a list in which the facility selection buttons B11 are arranged in ascending order of the current location. Each facility selection button B11 displays a number, a facility name, a distance from the current position to the facility, a location, and the like, which are assigned in ascending order of the current location. The user can select a facility by touching the facility selection button B11 or speaking the number displayed on the button in the same manner as described above. Since the facility selection button B11 displays the facility name, the distance from the current position, the location, and the like, in addition to the number, the user can obtain more detailed information on the searched facility.

  When the number of candidates searched for is larger than the displayable number of one page (for example, five), the control unit 18 displays the page button B9 displaying “2 pages” indicating that the next page exists. Is displayed. When the number of candidates is less than the displayable number of one page, the control unit 18 does not display the page button B9. When the user utters “niji” or “next”, the control unit 18 causes the display to transit to the display screen S2a_list of the facility selection 2 shown in FIG. The facility selection process in the list displayed on the display screen S2a_list is the same as described above. Further, the control unit 18 causes the display screen S2_list to display a page button B9 displaying the recognition word “1 page” for transitioning to the previous page. In this display screen S1a, when the user utters “Ipuji” or “Mae”, the control unit 18 transitions the screen displayed on the display unit 5 to the display screen S1 of facility selection 1 in FIG.

(Route selection)
As described above, when a facility is selected, the control unit 18 searches for a route 53 from the current position 51 to the facility as the destination 52, and displays the result on the display screen R1 of the route selection 1 shown in FIG. Display. As for the searched routes 53, the route 53 to be given the highest priority is displayed in different colors based on a preset route condition. At this time, the character 100 moves to an unobstructed position on the map according to the route guidance direction. That is, the character 100 is displayed at a position that does not obstruct the searched route display including the current position on the map. However, as described above, the character 100 is already displayed at the lower right of the screen, and does not disturb the searched route in the example of the display screen R1, so that there is no movement in this example.

  On the other hand, on the display screen R1, the control unit 18 displays a plurality of buttons on the side opposite to the character, that is, on the left side. If the number of buttons is small, a portion overlapping with the searched route 53 does not occur. Even if the number of buttons increases, there is a gap between the buttons, and a map and a route 53 can be seen. These buttons include a scale button B1. The operation when the user wants to change the scale is performed on the display screen R1a of the route selection 2 shown in FIG. 20, which will be described later.

  Further, on the display screen R1, a route condition button B12 displaying "route condition" which is an instruction word for changing the route condition is displayed. When the user speaks “Joken” or “Routo Joken”, the control unit 18 causes the display to transit to the route selection 3 display screen R1b shown in FIG. In this display screen R1b, next to the button of the "route condition", condition selection buttons B12a, B12b, B12c for selecting priority search conditions such as "highway", "general road" and "recommended" are displayed. You. On the display screen R1b, when the user utters “Ippando,” “Sokudo,” or “Suisho,” the control unit 18 outputs the corresponding response phrase and utters the search condition. The route is changed to the condition, and the route 53 having the highest priority in the changed search condition is displayed. For example, the control unit 18 determines each search condition such as "Yeah, let's go slowly on a general road." Outputs a response phrase indicating benefits. If it is a recommended route, it outputs a response phrase indicating the trust relationship with the character, "I will leave it to me."

  Then, on the display screen R1, a guidance start button B13 on which an instruction word "guide start" is displayed when guidance by the displayed route 53 is desired. When the user utters “Thank you,” “Thank you,” or “Thank you” on the screen on which the desired route 53 is displayed, the control unit 18 starts “guidance start. And output the response phrase “Tell me” to start route guidance.

  Further, when the user utters "Shuhen" for performing a peripheral search or "Return", "Takeshi" or "Redo" which is a return phrase, the control unit 18 outputs a response phrase of "Research", The screen is transited to the display screen of S1 shown in FIG. The subsequent peripheral search processing is as described above. For the utterance of the return phrase, the same processing is performed on the display screens S2, S2a, S2_list, S2a_list, R1, R1a, and R1b shown in FIGS.

  In response to the utterance of the return phrase on the display screens V1 and V1a of the voice recognition start shown in FIGS. 11 and 12, the control unit 18 outputs a response phrase "call again." The display is shifted to the display screen M1 shown in FIG. In response to the utterance of the return phrase on the display screens S1 and S1a of the peripheral search shown in FIGS. 13 and 14, the control unit 18 outputs a response phrase "from the beginning." The screen is transited to a recognition start display screen V1. As described above, even if the recognition word is the same, the display screen to be changed is different depending on the current display screen and the corresponding phase. In other words, by changing the display screen to which a transition is made for the return phrase, it is possible to eliminate excessive return and to save the user the trouble of starting over again.

  In this embodiment, a release phrase is prepared separately from the return phrase. When the user utters “Onkaikai”, “Syuryo” or “Genzaichi”, the display always returns to the display screen M1 waiting for voice recognition activation. At this time, the control unit 18 outputs a response phrase urging the next use, "Please call again." In this way, by registering a recognition word that returns at a different position and a recognition word that returns to a certain position according to the display screen or phase, the user can quickly transition to a desired screen according to the situation. It can be carried out.

  Further, when a recognized word that cannot be processed is uttered according to the screen or phase, the control unit 18 outputs a response phrase that clearly indicates that the recognized word cannot be processed, thereby providing the user with another word. Can be encouraged. For example, in the display screen V1a in FIG. 12 and the display screens S2, S2a, S2_list, and S2a_list in FIG. 15 to FIG. 18, the response phrase “What did you say?

《Change map scale》
The control unit 18 performs a process of changing a map scale, a volume, and a brightness as a process of changing a function according to the dialog. First, the procedure for changing the map scale will be described with reference to FIG. The same applies to the change of the map scale when the display screen S2 in FIG. 15 changes to the display screen S2a in FIG. 16 and when the display screen R1 in FIG. 19 changes to the display screen R1a in FIG.

  In the display screens V1 and V1a in FIGS. 11 and 12 in which the voice recognition has been started, when the user who wants to change the map scale utters “OK”, the control unit 18 shifts to the display screens A1 and A1a in FIG. The display screen A1 is a screen that has transitioned from the display screen V1, and the display screen A1a is a screen that has transitioned from the display screen V1a. On the display screen A1, the control unit 18 causes the response phrase “instruct something” to be output only when a transition is made from another screen (scene). As described above, even if the screen is switched, the character 100 may make an utterance prompting an instruction, so that the user can be made aware that the character 100 is always present. The display screen A1a is a screen for changing the map scale during navigation guidance.

  On the display screens A1 and A1a, a + button B1a and a-button B1b are displayed on the right side of the scale button B1. As described above, when the user touches the + button B1a, the control unit 18 gradually increases the map scale. In addition, when the user touches the-button B1b, the control unit 18 lowers the map scale stepwise. Further, in the present embodiment, when the user utters “Scramble” or “Shosai”, the control unit 18 recognizing the utterance gradually increases the map scale. When the user utters “Shokusho” and “Koiiki”, the control unit 18 recognizing the utterance lowers the map scale stepwise.

  When the scale is up, the control unit 18 can confirm what kind of change has been made, such as "I have expanded the area." Output. Thereby, the user can confirm by voice what processing has been performed. In addition, if the change of the scale exceeds the upper limit or the lower limit of the scale, the control unit 18 outputs a response phrase notifying that the change cannot be performed, such as "But, it is a limit". This prevents the user from repeating useless change instructions without confirming whether the upper limit or the lower limit has been reached.

  When the user utters a value of a desired scale such as "Juyutoru" or "Ichikiro", the control unit 18 recognizing the utterance directly changes the map scale to the uttered value. . At this time, the control unit 18 outputs a response phrase corresponding to the input value, such as “10 meters” or “1 km”, as a response phrase corresponding to the utterance of the user. As a result, the user can check the level of the scale designated by the user.

  Then, when the user utters “Sukeru” or utters a return phrase, the control unit 18 outputs a response phrase notifying that the scale change processing has been completed, such as “Setting completed”. . The processing with the release phrase is the same as described above.

  Further, in the case of the display screen A1, the home button is displayed, and when the user touches this button or speaks “judge”, the control unit 18 performs the following processing. First, when home registration has not been made in advance, the control unit 18 outputs a response phrase urging home registration, such as "I say home, but I will not tell me." As a result, a process required as a premise for executing a specific function is prompted by voice, so that the user can understand what is necessary to use the function. If the home registration has been made, the control unit 18 outputs a response phrase “Yes, go home.” And searches for a route to home. This allows the user to get the impression that the character will come back together.

  In the case of the display screen A1a, certain functions are restricted because navigation is being performed. That is, the neighborhood search and the route guidance to the home cannot be executed on the display screen A1a. Therefore, even if the user utters “Shin”, a response phrase “What did you say?” Is output, and the peripheral search is not performed. In addition, even if the user utters “Jitaku”, the control unit 18 outputs a response phrase “What do you say?” And does not search for a route to home. In this way, the user can know from the response phrase that the processing cannot be performed.

《Volume change》
The procedure for changing the volume will be described with reference to FIG. In the display screens V1 and V1a in FIGS. 11 and 12 in which the voice recognition has been started, when the user who wants to change the volume speaks "OnRyo", the control unit 18 transitions to the display screens A2 and A2a in FIG. The display screen A2 is a screen that has transitioned from the display screen V1, and the display screen A2a is a screen that has transitioned from the display screen V1a. In the display screen A2, the control unit 18 outputs a response phrase "instruct something." Only when a transition is made from another screen (scene). As described above, even if the screen is switched, the character 100 may make an utterance prompting an instruction, so that the user can be made aware that the character 100 is always present. The display screen A2a is a volume change screen during navigation guidance.

  On the display screens A2 and A2a, a + button B5a and a-button B5b are displayed on the right side of the volume button B5. When the user touches the + button B5a, the control unit 18 increases the volume stepwise. In addition, when the user touches the-button B5b, the control unit 18 gradually lowers the volume. Further, in the present embodiment, when the user utters “app” or “large”, the control unit 18 recognizing the utterance increases the volume stepwise. When the user utters “Noun” or “Small”, the control unit 18 that recognizes the utterance gradually lowers the volume.

  Then, the control unit 18 outputs a response phrase that can confirm what kind of change has been made, such as "volume up" when the volume is up, and "volume down" when the volume is down. . Thereby, the user can confirm by voice what processing has been performed. In addition, if the volume exceeds the upper or lower limit of the volume when the volume is changed, the control unit 18 outputs a response phrase indicating that the volume cannot be changed, such as "Boooooo, it is a limit". This prevents the user from repeating useless change instructions without confirming whether the upper limit or the lower limit has been reached.

  Further, when the user utters a desired volume value such as “Zero”, “Ichi”, or “Ni”, the control unit 18 that recognizes the value directly changes the volume to the uttered value. . At this time, the control unit 18 outputs a response phrase corresponding to the input value, such as “zero”, “1”, “2”, as a response phrase corresponding to the utterance of the user. . Thereby, the user can confirm the volume level designated by the user.

  Then, when the user utters “OnRyo” or utters a return phrase, the control unit 18 outputs a response phrase indicating that the volume change processing has been completed, such as “Setting completed”. The processing with the release phrase is the same as described above. Other processes are the same as the processes described on the map scale.

《Change brightness》
The processing procedure for changing the luminance will be described with reference to FIG. In the display screens V1 and V1a in FIGS. 11 and 12 in which the voice recognition has been started, when the user who wants to change the luminance speaks “KIDO”, the control unit 18 transitions to the display screens A3 and A3a in FIG. The display screen A3 is a screen that has transitioned from the display screen V1, and the display screen A3a is a screen that has transitioned from the display screen V1a. On the display screen A3, the control unit 18 outputs a response phrase "instruct something." Only when a transition is made from another screen (scene). As described above, even if the screen is switched, the character 100 may make an utterance prompting an instruction, so that the user can be made aware that the character 100 is always present. The display screen A3a is a luminance change screen during navigation guidance.

  On the display screens A3 and A3a, a + button B6a and a-button B6b are displayed beside the luminance button B6. When the user touches the + button B6a, the control unit 18 increases the luminance stepwise. When the user touches the-button B6b, the control unit 18 lowers the luminance stepwise. Further, in the present embodiment, when the user utters “app” or “ak”, the control unit 18 that recognizes this raises the luminance stepwise. When the user utters “No” or “Easy”, the control unit 18 recognizing the utterance gradually lowers the luminance.

  Then, the control unit 18 outputs a response phrase for confirming what kind of change has been made, such as “brightness up” when the brightness is up, and “brightness down” when the brightness is down. Thereby, the user can confirm by voice what processing has been performed. In addition, when the luminance exceeds the upper or lower limit of the luminance when the luminance is changed, the control unit 18 outputs a response phrase that informs that the luminance cannot be changed, such as “Boooo, it is a limit”. This prevents the user from repeating useless change instructions without confirming whether the upper limit or the lower limit has been reached.

  When the user utters a desired luminance value, such as "zero", "ichi", or "ni", the control unit 18 recognizing the utterance changes the luminance directly to the uttered value. Let it. At this time, a response phrase corresponding to the input value is output as a response phrase corresponding to the utterance of the user, such as “zero”, “1”, “2”. Thereby, the user can confirm the level of the luminance designated by the user.

  Then, when the user utters “KIDO” or utters a return phrase, the control unit 18 outputs a response phrase indicating that the brightness change processing has been completed, such as “SETTING COMPLETED”. The processing with the release phrase is the same as described above. Other processes are the same as the processes described on the map scale.

  In addition, in the display screens A1 and A1a, the control unit 18 makes a transition to the display screens A2 and A2a or the display screens A3 and A3a by speaking “onkyo” or “kid”. In the display screens A2 and A2a, the control unit 18 makes a transition to the display screens A3 and A3a or the display screens A1 and A1a by speaking "KIDO" or "SUKERU". In the display screens A3 and A3a, the control unit 18 makes a transition to the display screens A1 and A1a or the display screens A2 and A2a by speaking “Skuru” or “Onryo”. In this way, by making the screens of the change processing of the quantitative level mutually translatable, it may be convenient for the user who wants to change the settings collectively.

<< Time-out processing >>
Next, the timeout process will be described. The time-out process is a process of terminating the process when a predetermined time has passed without any voice input from the user from the time when the control unit 18 started the predetermined process. Then, during a period from the start of the predetermined process to the elapse of the predetermined time, the control unit 18 outputs a voice prompting voice input as a response phrase of the character.

  More specific processing will be described with reference to FIG. As the timeout process, timeouts V1, S1, S2, R1, A1, and A1a are set. First, the processing of the timeout V1 will be described. When there is no voice recognition for 15 seconds after the voice recognition is activated on the display screen V1 or V1a, the control unit 18 outputs, as the timeout status 1, a response phrase urging the user to input voice. Here, since the screen is a voice recognition start screen, a response phrase requesting a voice input “Hey, say something” is output. Then, if there is no voice recognition for 15 seconds from the output of the response phrase, the control unit 18 outputs, as the timeout status 2, a response phrase for notifying that the voice recognition has ended, and ends the voice recognition. Here, a response phrase that looks somewhat angry is output because there is no voice input, such as "N, already."

  The process of the timeout S1 is as follows. When there is no voice recognition for 15 seconds after the transition to the display screens S1 and S1a, the control unit 18 outputs a response phrase urging voice input as timeout status 1. In this case, since the screen is a peripheral search screen, a response phrase asking for the destination, such as "Hey, hey, where are you going?", Is output. Then, if there is no voice recognition for 15 seconds from the output of the response phrase, the control unit 18 outputs, as the timeout status 2, a response phrase for notifying that the voice recognition has ended, and ends the voice recognition. Here, a response phrase that looks somewhat angry is output because there is no voice input, such as "N, already."

  The process of the timeout S2 is as follows. If there is no voice recognition for 15 seconds after the transition to the display screens S2, S2a, S2_list, and S2a_list, the control unit 18 outputs a response phrase urging voice input as timeout status 1 if there is no voice recognition. Here, since the screen is for selecting a facility, a response phrase for prompting the user to select a facility is output, such as "Did you not decide yet?" Then, if there is no voice recognition for 15 seconds from the output of the response phrase, the control unit 18 outputs, as the timeout status 2, a response phrase for notifying that the voice recognition has ended, and ends the voice recognition. Here, a response phrase that looks somewhat angry is output because there is no voice input, such as "N, already."

  The process of the timeout R1 is as follows. If there is no voice recognition for 15 seconds after transitioning to the display screens R1, R1a, R1b, the control unit 18 outputs a response phrase urging voice input as timeout status 1. In this case, since the screen is for selecting a route, a response phrase for notifying that the next process will proceed even if there is no voice input, such as "I will guide you if you are silent", is output. Then, if there is no voice recognition for 15 seconds from the output of the response phrase, the control unit 18 outputs, as the timeout status 2, a response phrase for notifying that the voice recognition has ended, and ends the voice recognition. Here, a response phrase notifying that the next process is to be started is output, such as "Guidance start. Will you drive as you say?"

  The processing of the timeout A1 is as follows. The control unit 18 outputs a response phrase for prompting voice input as timeout status 1 if there is no voice recognition for 15 seconds after transitioning to the display screens A1, A2, A3, A1a, A2a, A3a. Here, since the screen is a setting change screen, a response phrase urging the setting change, such as "instruction, request", is output. If there is no voice recognition for 15 seconds from the output of the response phrase, the control unit 18 outputs, as the timeout status 2, a response phrase notifying that the voice recognition is completed, To end. Here, a response phrase that looks somewhat angry is output because there is no voice input, such as "N, already."

  The processing of the timeout A1a is as follows. The control unit 18 shifts to the display screens A1, A2, A3, A1a, A2a, and A3a, and when there is no voice recognition for 15 seconds after an input for instructing a change in setting is made by button selection or voice, As the timeout status 1, a response phrase prompting voice input is output. Here, a response phrase, such as "instruction, request", which prompts an instruction to determine a setting change by voice input is output. Thereafter, if there is no voice recognition for 15 seconds, the control unit 18 outputs a timeout phrase 2 as a response phrase for notifying that the voice recognition has ended, completes the setting change, and ends the voice recognition. Here, a response phrase for notifying that the setting has been changed and that the setting change has been completed is output.

  The timeout process may occur frequently, but as described above, the user does not get bored by changing the contents of the response phrases of the timeout status 1 and the timeout status 2 in accordance with the display screen and the phase. Good.

[Effects]
According to the above-described embodiment, the system does not provide information in response to a unidirectional instruction of a user who is a vehicle occupant, but obtains information that the user wants to know by interacting with a character. This will increase the fun of operation and driving, and will give you the feeling of communicating with the character, so you will not get tired of it. In addition, since the user is motivated to operate the system in order to interact with the character, the functions of the system are effectively used.

  A response phrase is registered so that a predetermined character can be recognized by a voice output from the system as a speaker having a specific personality. And you can get close to it.

  As the dialogue, for example, the system is set so that at least one round trip exchange of the start of the utterance, the response thereto, the reply to the response is performed, so that the system does not simply perform the processing according to the user's command, The user can get a feeling that the character is intervening between himself and the system and providing the service.

  By using voice recognition, the user can make the output easier or faster than manual operation, so that the user actively uses the voice recognition and gives the user more opportunities to interact with the character. be able to.

  In particular, even when it is difficult for the driver to obtain desired information while driving due to difficult manual operations or limited manual operations, etc., it is possible to enjoy conversation with the character by using voice recognition. Desired information can be obtained.

  When a plurality of selections need to be made to output information, operation by voice input is easier for the user than when manual operation is required for each selection. As information output through a plurality of selections, for example, information having a hierarchical structure or information that cannot be output unless a plurality of operations are performed is less burdensome to the user than performing a plurality of manual operations.

  In particular, a process of outputting information obtained by sequentially narrowing down from a plurality of candidates, such as a facility search and a current location search, is an operation for moving the vehicle itself such as a brake or an accelerator. Unlike an operation for informing something to the outside during traveling like a blinker for safety, it is difficult to directly execute the operation by hand, so that it is suitable for an operation by voice recognition.

  The user can proceed with the predetermined process sequentially by being prompted by the voice of the character to make a selection. For example, as a response phrase that guides the user to the next selection, if the user's voice “peripheral” is recognized in the peripheral search, a voice asking for the destination is output, such as “hey, where are you going?” And you know exactly what to say next.

  If there is no next selection, the sound of the character indicating this is output, so that the user knows that it is no longer necessary to proceed with the processing, and can determine whether to end the instruction or to perform another processing. . For example, if the voice of the character indicating that there is no next selection is recognized as the voice of the user "Familys" in the surrounding search, and if "Do you go to the family alone?" Other decisions can be sought.

  The user can acquire information on facilities around a desired point, such as the current location, without having to perform any troublesome manual operations, while enjoying the conversation with the character.

  Since the icons indicating the facilities located in the vicinity of the search are relatively highlighted as compared to the map, the information of the facilities required by the user is conspicuous on the map, so that the user can easily grasp the location of the facility, The voice serves as a guide when selecting a desired facility. In particular, the icons are displayed in color and the map is displayed in gray scale, so that the icons are clearly visible.

  Since the icon of the facility is displayed so that the order of proximity to the current location can be distinguished, it can be used as a guide for the user to select the facility. In particular, since the information inherently indicates the rank, such as a number or alphabet, the meaning of the rank can be easily grasped.

  Since the voice of the user selecting one of the facilities is recognized and the route to the selected facility is searched and displayed based on the content according to the displayed icon, the user can select the facility by using the facility name rather than selecting the facility. , Can be easily selected with the contents corresponding to the displayed icon. In particular, since the displayed number may be spoken, the facility can be selected using words that are easier to remember than the facility name.

  When the user does not want the searched route, the user can instruct the search again while interacting with the character, so that the trouble and boring feeling when starting again can be reduced.

  By seeing the appearance of the character with which the user interacts on the display screen, the user becomes familiar and willingly wants to use the system to see the appearance.

Since the character is displayed at a position on the map that does not obstruct the display of the searched route, the display of the searched route can be maintained while the display of the character is enjoyed.
If the character moves to the opposite side of the searched path, the display area of the item may overlap the searched path, but each item is smaller than the character and the display area of the item is Since the image has a visible portion, the image behind is easier to see than the searched route overlaps with the character.

  Since the voice of the character is randomly selected and output from a plurality of preset response phrases excluding the already output response phrase, only the same phrase is not output, and the user is not bored.

  A list in which a plurality of different response phrases are registered for a common recognition word is set, so that even if the user utters the common content, the character can respond with different expressions, and Even if the same processing is realized, it is possible to enjoy what kind of response comes from the character.

  Although the character is the same person as the standard ray, the transformed ray, and the chibi ray, there are multiple display modes and different phrases are registered as output voices for each of the multiple display modes. However, the content of the utterance is different depending on the plurality of display modes, and the user can enjoy the change while interacting with the same person. In particular, because it is a standard thing, a thing transformed by changing clothes and hairstyles, and a change of the head and body, it gives the user various impressions such as mature, childish, cute, beautiful, etc. Do not let.

  Since the recognition word is displayed as an item on a button or the like, the user can understand what to say by looking at the displayed item in order to execute a predetermined process.

  Recognition words include recognition words that can be recognized in common regardless of the display screen, and recognition words in which recognition is limited to those displayed on the display screen. Regardless, while maintaining the convenience of the necessary functions, the possibility of erroneous recognition can be reduced by the recognition word whose recognition is restricted. With respect to the recognition word commonly used in a plurality of types of display screens, the possibility that the function is limited depending on the display screen is reduced, and the convenience can be maintained. In particular, words such as a return phrase and a release phrase that need to be used on any screen, because they are words that transition to another display screen. On the other hand, the recognition word displayed on the display screen and the recognition word to be searched are less required to recognize other words and phrases, and the need to reduce the number of recognition words to prevent erroneous recognition is high.

  Since the state of the function that changes quantitatively can be directly set to the desired quantitative level by voice recognition, the desired state can be immediately changed as compared with a case where the state changes stepwise between a small value and a large value. The value can be set as a value, the user's effort is reduced, and the time restricted by the operation is reduced. In particular, it is possible to display buttons such as +,-, and scale by selecting buttons such as volume, brightness, and scale, and to save the trouble of selecting +-or sliding up and down step by step on the scale.

  As a recognition word, an instruction word corresponding to a function that changes quantitatively and a number indicating a quantitative level are set. When the user speaks an instruction word and a number corresponding to a desired function, the amount of the function is reduced. The target level can be raised or lowered directly to the level of the number. In particular, since the descriptive words are "Onryo", "Kid", "Skuru", and the numbers are "Ichi", "Ni", "Nikuro", etc., the names of functions that are intuitively understandable to the user Can be entered using and numbers.

  Since the instruction word corresponding to the function is displayed on the button for selecting the function, the user can select the function by speaking the instruction word displayed on the button, which is easy for the user to understand.

  Since the button for selecting a function displays the value of the current quantitative level of the function, the user can confirm the current quantitative level by looking at the value displayed on the button. Thus, it can be determined whether the value should be increased or decreased to a desired value. For example, on a map scale, if a small scale value is displayed on a button and the user says a larger value, the scale value displayed on the button changes directly to that value, and immediately You can see a wide range of maps. For example, if a large scale value is displayed on a button and the user says a smaller value, the scale value displayed on the button also changes directly to that value, and a detailed map is displayed immediately. Can be seen.

  When a predetermined period of time has elapsed without the input of a voice from the user after the start of the predetermined process, a timeout process for terminating the process is performed, so that an erroneous operation caused by continuing voice recognition for a long time may be prevented. .

  Since the character outputs a voice prompting the user to input a voice during a period from the start of the predetermined process to a lapse of a predetermined time, if the user has forgotten to start the process, the character is prompted to input a voice. Can be.

[Other embodiments]
The present invention is not limited to the above-described embodiment, and can be configured in various forms including the forms exemplified below.

《Register genre》
A genre registration function that allows the user to display only desired items on the display screen of the display unit 5 for items of the genre of the peripheral search will be described. Thus, by listing in advance the genres that the user will frequently use, it is possible to create a user's original peripheral search screen. More specifically, the control unit 18 causes the display unit 5 to display a table of items that allow the user to select which of the items corresponding to the genre recognition words should function as the recognition word. When the user selects a desired item from the table, the control unit 18 sets the selected item on a page for displaying a button on the display unit 5.

  An example of such a display screen will be described with reference to FIG. First, the display screen (1) is displayed on the lower left of the map screen while the control unit 18 displays the character 100 on the lower right of the map screen displayed on the display unit 5 in the same manner as in the above-described embodiment. In addition, a peripheral button B3 for selecting and searching for peripheral facilities by genre is displayed.

  On this display screen (1), when the user touches the peripheral button B3 or utters two words "Rei" and "Shihen" registered as recognition words for instructing activation of voice recognition and peripheral search. The control unit 18 recognizing this makes a transition to the one-shot genre selection screen shown in the display screen (2).

  As described above, the display screen (2) displayed by the two-word voice recognition activation displays a table including a plurality of items by arranging a plurality of buttons displaying genre names. When the user selects each button or speaks a genre name in the table including the items of the genre name, the control unit 18 searches for facilities of the genre as shown in the display screen (3). The searched facilities are numbered in order from the closest to the current location 51 and displayed on the map.

  When the user touches the desired facility icon displayed on the display screen (3) or speaks the number displayed on the desired facility icon, the control unit 18 searches for a route from the current location to the selected facility. When executed, the searched route 53 is displayed in different colors as shown in the display screen (4).

  At this time, the character 100 moves to an unobstructed position on the map according to the route guidance direction. That is, the character 100 is displayed at a position that does not obstruct the searched route display including the current position on the map. Further, when the user speaks guidance start, the control unit 18 starts route guidance as shown in the display screen (5). Even during this route guidance, the character 100 is displayed at a position where the display of the searched route 53 including the current position 51 on the map is not interrupted.

  At the bottom of the table on the display screen (2), three buttons of “return”, “change”, and “current location” are displayed. Among them, the “return” button is a button that, when the user touches or utters “return”, the control unit 18 that recognizes this makes a transition to the previous screen. The “current location” button is a button that, when the user touches or utters “Genzaichi”, the control unit 18 recognizing this touch makes a transition to a display screen displaying the current location 51. Here, the screen transitions to the display screen (1) both when the “return” button is selected and when the “current location” button is selected.

  When the user touches the “change” button or utters “change”, the control unit 18 recognizing this touch makes a transition to a one-shot genre change screen shown in the display screen (6). On this one-shot genre change screen, the genres currently registered as the one-shot genre selection screen are displayed in the same arrangement order. Here, when the user touches a button of any genre or utters a genre name, the control unit 18 recognizing this touches the large item display screens (7) to (10) to which each genre name belongs. Transition to any of

  For example, when the user selects “station”, the display transits to a display screen (7) displaying a genre name belonging to the major item “hotel / public facility / other” to which “station” belongs. On the display screen (7), genre names displayed on the display screen (2) are displayed in a specific dark color, and genre names not displayed on the display screen (2) are displayed in a lighter color. For example, “station” displayed on the display screen (2) is displayed in blue characters, and “parking lot” not displayed on the display screen (2) is displayed in gray characters.

  Here, when the user touches the genre name displayed on the display screen (7) or utters the genre name, the control unit 18 recognizing the genre name displays the selected genre name on the display screen (7). The genre name is not displayed. At this time, the genre name is changed to a light color display. For example, when the user selects "station", the character of "station" becomes gray.

  For example, when the user touches the genre name displayed on the display screen (7) or utters the genre name, the control unit 18 recognizing the genre name displays the selected genre name on the display screen (2). The genre name to be made. At this time, the genre name is changed to a specific dark color display. For example, when the user selects “parking lot”, the text “parking lot” turns blue.

  When a genre name belonging to a hospital or clinic such as “general hospital” is selected on the display screen (6), the display transits to the display screen (8). When a genre name belonging to shopping such as "convenience store" is selected, the display transits to a display screen (9). When a genre name belonging to a restaurant such as “family restaurant” is selected, the display transits to a display screen (10). In each of the display screens, the selection of the genre name to be displayed on the display screen (2) and the selection of the genre name not to be displayed are as described above.

  In addition, when the user selects the “▽” button for sending a page on the display screen (7), the display transits to the next display screen (8). On the display screen (8), when the button for returning to the page “△” is selected, the display transits to the display screen (7). Thus, “▽” and “△” function as buttons for switching pages between the display screens (7) to (10).

  As described above, in each of the display screens (7) to (10), after changing the genre name, when the user touches the “return” button or speaks “return”, the display screen (6) is displayed. The genre name to be displayed is displayed, and the genre name not to be displayed is not displayed. Then, when the user touches the “return” button or speaks “return”, a transition is made to the display screen (2) reflecting the display of the changed display screen (6). In the above example, “parking lot” is displayed at the position of “station”, and “station” is not displayed.

  To return to the default display, when the user selects the “Return to Default” button or utters “Return to Default” on the display screen (6), the control unit recognizes this. 18 returns to the default genre name and its arrangement. Then, when the user touches the “return” button or speaks “return”, the display screen transitions to the display screen (2) that has returned to the default setting.

  As described above, in the display screen (6) and the display screen (2) reflecting the display screen, the genre name can be selected for each position to be displayed. That is, when “station” in the upper left is selected on the display screen (6), the control unit 18 recognizes which display position on the display screen together with the selected genre name. Then, the control unit 18 can cause one of the genre names selected on the display screens (7) to (10) to be displayed at the display position, that is, the upper left position. Therefore, when it is desired to change the arrangement of the genre names on the display screen (2), a genre name at a desired display position is selected on the display screen (6), and this is set to the genre name desired to be displayed at the display position. It can be realized by changing. In this case, it is possible to select the same genre name to be displayed at different positions. For example, the genre name “station” may be displayed at the upper left, and “station” may be displayed below the genre. As described above, when the same genre name is displayed at a plurality of places on the display screen (2) for the frequently used genre name, the genre name can be easily touched and selected.

  The control unit 18 allows the user to touch and drag a desired genre name on the display screen (6) and then release the genre name at a desired position. If the display position can be changed, the display position may be easily changed.

  Further, the number of genre names that can be displayed on the display screen (2) is limited to a predetermined number. For example, there are 25 here. Therefore, when 25 genre names to be displayed have already been registered, the genre names to be displayed cannot be further increased.

  As described above, if the user selects only frequently used items from the displayed list of items, the recognition words are limited, and erroneous recognition can be reduced. The selected recognition word is registered in a predetermined memory area, for example, by rewriting from a default state, putting it into an empty area, or rearranging the already contained words. In this way, the limited memory area can be effectively used.

  The setting of the item by the user may be set for each of a plurality of pages to be displayed on the display unit 5, as shown in FIGS. 13 and 14 in the above embodiment. . For this reason, even if the items that can be displayed on one page of the display screen are limited, bringing the items frequently used by the user to the top page saves the trouble of switching pages to display the desired items. .

  The large item corresponding to the recognition word including a plurality of concepts and the middle item corresponding to the recognition word corresponding to the plurality of concepts can be displayed on the same page, so that even when the user wants to search for the middle item, It is not necessary to change the hierarchy or page, and a desired item can be directly selected.

  For example, a large general concept item including a large number of candidates such as “hospital” is a convenient item for a user who wants to search from as many candidates as possible. The middle items such as “Internal Medicine” and “Pediatrics” included in the concept of “hospital” are convenient for users who want to immediately obtain desired facility information from a small number of candidates.

  The information on the classification of the facilities can be efficiently specified by classifying the information into stages and hierarchies like large items and medium items. That is, one or more middle items belong to the large items.

  Examples of major items include "hotels / public facilities / others", "hospitals / clinics", shopping, and "restaurants". Examples of sub-items belonging to “hotel / public facilities / other” include “station”, “IC (interchange) / JCT (junction)],“ post office ”,“ government office ”,“ toilet ”,“ parking lot ”. , "Hotel", "Bank Shinkin", "School", "Gas station". Examples of middle items belonging to “hospital / clinic” include “general hospital”, “internal medicine”, pediatrics ”,“ surgery ”,“ obstetrics and gynecology ”,“ dental ”,“ ophthalmology ”,“ otolaryngology ”, There are “Orthopedic surgery”, “Dermatology”, “Urology”, “Clinical medicine”, “Neurology”, “Anal medicine”, “Animal hospital” and the like. Examples of the middle items belonging to “shopping” include “convenience store”, “drug store”, “department store”, “shopping mall”, “supermarket”, “car supplies”, “home improvement center”, “home appliances”, and the like. Examples of the middle items belonging to “restaurant” include “family restaurant”, “fast food”, “Japanese food”, “Western food”, “Chinese food”, “ramen”, “roasted meat”, “sushi”, “tonkatsu”, There are "udon", "curry", "beef bowl" and so on.

  Note that one or more small items may further belong to each medium item. By classifying the items in stages and hierarchies such as large items, medium items, and small items, efficient designation can be performed from a large number of items. In the case where only one item belongs, it is actually equivalent to an item having no item at that level. That is, when there is only one medium item belonging to the large item, the medium item and the small item may not be present up to the large item. When there is only one small item belonging to the middle item, the small item may be omitted up to the middle item. When a large item is specified, all the middle items belonging to it are specified. When a certain middle item is specified, all the small items belonging to the middle item are specified. The control unit 18 performs the processing.

  Note that a phrase that is related to a phrase displayed as an item but is not displayed as an item may be registered as a recognition word. For example, without saying the recognition word itself displayed in the item, it is sufficient to say a phrase related to the recognition word, so that the storage of the user's item name is ambiguous or the user is unfamiliar with the operation. Even, you can search.

  For example, even if the phrase displayed as an item is a large item "hospital" and the middle item "internal medicine" or "pediatric" is not displayed, "internal medicine" or "pediatric" You may register as a recognition word which can be voice-recognized. In this way, even if the middle item is not displayed, if the more specific middle items “internal medicine” and “pediatrics” associated with the large item “hospital” are referred, the middle item is searched, Can quickly obtain information on the necessary facilities.

  The item of the recognition word that may be confused may be set to be displayed on another page by the user setting or the default setting as described above. For example, words that include similar sounds, words that are likely to be confused when actually recognized, and the like do not line up on the same page and are not candidates for recognition at the same time, so that erroneous recognition can be reduced. Words containing similar sounds include, for example, the same 50 sounds and the same kanji, such as “family restaurant” and “fast food”, “hospital” and “beauty salon”, and “Western food” and “Japanese food”. Words.

  In this way, since the sound recognition phrase that is confusing even from the character is not displayed on the same page, the user also needs to input one of them, thereby reducing erroneous recognition. A phrase that is highly likely to be confused when actually recognized is, for example, a different phrase that is recognized for the same utterance based on a record of past recognition results. In this way, it is possible to exclude a combination in which an erroneous recognition has actually occurred on the same page.

《Character display》
Various modes are also possible for character display. In the display screens (4) and (5) in FIG. 26 described above, the control unit 18 moves the character 100 to the left and right so that the character 100 displayed on the screen does not overlap the current position and the searched route 53. ing. For example, the character 100 and the display of the searched route 53 may be close to each other on the display screen. In this way, the user can be made to feel as if the character 100 is not disturbing the route search service, so that the user can have a better feeling.

  The movement of the character 100 may disappear once and then appear at the destination, or may be moved while continuing the display. If the user moves frequently, the user may feel annoyed. However, while the character 100 can appeal to the user, the user who wants to continuously watch the character 100 can enjoy the operation of the moving character 100. it can.

  The control unit 18 may cause the display unit 5 to display whether or not voice recognition is activated and accepted. With this configuration, the user can visually recognize whether or not the user can perform a voice operation. Whether the voice recognition is accepted or not is displayed by changing the color of the display screen. In this way, for example, the state of voice recognition can be immediately felt through the user's vision. In particular, when speech recognition is accepted, the color is a normal color, and when not accepted, the color is a gray scale. This allows the user to intuitively recognize whether or not speech recognition is being accepted.

  The control unit 18 may display on the character whether or not speech recognition has been accepted. This makes it easy for the user to notice because the character can determine whether or not the operation by voice is possible by looking at the character.

  As a mode for displaying on the character, for example, a mode in which the state of the character clearly changes is used. In this way, for example, the state of voice recognition can be immediately felt. Examples of the manner in which the state of the character clearly changes include, for example, adding an object to the character, changing the color or form of the character, making a specific pose or gesture, displaying speech in a balloon, and the like. In this way, for example, a user who knows the state of a normal character immediately notices the change by comparison with the normal state.

  As a mode of adding an object to the character, for example, equipment related to sound such as a headset, headphones, earphones, and a microphone is attached to the character. In this way, the user is reminded of voice recognition, which is a function related to sound. As a mode of changing the color and form of the character, for example, a hairstyle, its color, changing into another costume, and the like are used. This makes it easier to understand the difference from the normal state. In particular, if the character's ears are raised, the character will show that he or she is trying to hear the sound well. Furthermore, as a pose or gesture, for example, even if a gesture is made to put a hand behind the ear, the figure shows that the user is trying to hear the sound well.

《Use of nickname》
The control unit 18 may insert the voice of the user's name registered in the database 19 in advance into the response phrase that is the voice output by the character. That is, the control unit 18 causes the user's name to be said in a nickname expression during the dialogue with “Kirishima Rei”. For example, the character can be called, for example, "K-kun" or "Yu-kun".

  For example, “Ray, Shuhen” is registered as a startup word that activates voice recognition and peripheral search, and a user whose nickname is registered as “You” on the map display screen performs a peripheral search on “Kirishima Rei”. An example of the dialogue in the case of performing this is shown below. “” Indicates the spoken frace.

Yu-kun: "Ray, surroundings" → voice recognition start-up → transition to the surrounding search genre screen Ray: "What-you-kun, I'm busy."
Yu-kun: "Internal Medicine" → transit to the map screen, display surrounding internal medicine icons Rei: "What's wrong? Are you alright? Where's the doctor?"
Yu-kun: "Ni" (number 2)
Ray: "Okay, 2nd." → Display the information of the 2 internal clinics on the map Yu-kun: "Search" → Search for the route and display it on the map Ray: "Wow? Go here?"
Yu-kun: "Please."
Ray: "Okay, leave it to me."

In this way, the user can feel more familiar with the character by being called by his / her nickname in the conversation.
In addition, since the voice of the nickname is inserted in the voice output at the start of the dialogue, the user may be called by his / her own name and may be able to draw the user's attention.
Furthermore, when the voice including the character's name is recognized, the voice of the user's name is inserted in the output voice, so that the names are called to each other, and the user gets a more intimate feeling. be able to.

As the dialogue progresses, the frequency of inserting the user's name into the voice output by the character may be reduced. In this way, for example, although the name is called at first, the frequency of calling is reduced thereafter, so that a conversation between two people who are accustomed to each other can be produced.
Further, voice data corresponding to the Japanese syllabary may be registered in the database 19 in advance, and the voice of the nickname selected by the user from the Japanese syllabary may be inserted during the conversation. In this way, for example, the memory capacity can be saved as compared with a case where a plurality of names are registered in advance.

《Post》
When the user finds the control / inspection place, the control unit 18 transmits the position information on the control place to the information collection server in accordance with the input of the user's voice corresponding to the recognition word registered in the database 19 in advance. By doing so, the function of posting can be executed. Further, the control unit 18 can display the posted positional information on the enforcement place on the display unit 5 together with the map in response to the distribution from the information collection server. For this reason, the navigation device includes a communication unit connected to the control unit 18 and transmitting and receiving information to and from the outside.

  The communication unit is connected wirelessly or by wire to a communication device in the vehicle having an Internet connection function. For example, the communication unit can be realized by a Wi-Fi (registered trademark) connection, a Bluetooth (registered trademark) connection, or a USB connection with a mobile phone such as a smartphone or a wireless LAN router having a tethering function. Such a communication device may be incorporated in a navigation device.

First, the process of posting by a touch operation is as follows.
1. 1. The user finds a place to check and check while traveling. 2. Touch the button that instructs the setting of the posting place on the display screen. 3. The current position on the map when the button is touched is set as the posting location, and an icon is displayed at the corresponding position. 5. Touch the posting button on the standby screen while parked or stopped 5. Display a list of multiple posting locations set by 1-3 6. Touch one of the places you want to post. 7. Touch post button for final confirmation 8. Transmit the information of the selected posting location to the server that collects the posting locations. 9. The server collecting the posting location registers the received information as a regulatory location. 10. The server collecting the posting location distributes the registered information. Receive and display the distributed information

  In addition, between 6 and 7, selection of the target is Orvis, N system, control, check, etc., selection of target direction such as driving lane, opposite lane, right direction, left direction, etc., selection of implementation period Etc. can also be performed.

  In the case of posting by such a button operation, a plurality of button operations are required since the vehicle goes through a plurality of hierarchical procedures after finding a posting place during traveling.

  However, in this embodiment, posting can be performed in response to a user's voice input. That is, when the user utters the recognition word registered in the database 19 in advance, the control unit 18 recognizes the recognition word, and notifies the communication unit of the current position at the time of the utterance to the server as a posting place via the communication device. Send. The server registers the received information as a control place and distributes the registered information. The communication unit receives the distributed information via the communication device, and the control unit 18 displays the enforcement place on a map based on the received information. Therefore, the operation can be easily and quickly performed without the trouble of the button operation.

  As described above, the control place includes the Orvis and the N system, but it is particularly preferable that the control place is a check place where the execution position and time change, such as a control and check area. By doing so, it is possible to collect, by posting, information on a control place where it is difficult to register a position in advance.

  The position information may be, for example, the current position or the coordinates of the center position of the map. In this way, the control place can be specified by the information that can be obtained reliably and easily, and since the voice recognition is used, the deviation from the actual control position may be small.

  As the recognition word, a phrase that activates speech recognition and a phrase that starts accepting a post may be registered. In this way, the user can easily execute the multi-stage operation of voice recognition and post acceptance by speaking the phrase that activates speech recognition and the phrase that starts accepting posts. .

  The phrase for activating the speech recognition and the phrase for starting the reception of the post may be registered, for example, as separately separated phrases. In this way, for example, it may be possible to prevent the reception of the post from being started at the same time as the start of the voice recognition, and to prevent the occurrence of erroneous recognition. In addition, as a phrase that activates speech recognition and a phrase that starts accepting a post, for example, the phrase may be set as a series of phrases. In this way, for example, the reception of the post can be started in one shot together with the start of the voice recognition, so that the posting can be immediately made possible.

  As a recognition word, if a phrase that activates speech recognition and a phrase that causes posting are registered, the user speaks a phrase that activates speech recognition and a phrase that causes posting, thereby performing voice recognition and posting. Multi-stage operation can be easily performed.

  The phrase for activating the speech recognition and the phrase for posting may be registered, for example, as separately separated phrases. By doing so, for example, it may be possible to prevent a message from being posted at the same time as the start of voice recognition and being posted by mistake. The phrase for starting the speech recognition and the phrase for posting may be set as, for example, a series of phrases. In this way, for example, the posting can be performed in one shot at the start of the speech recognition, so that the posting can be performed immediately, and the gap between the control place and the posting place can be minimized.

  Note that the recognition word for posting may be shorter than other recognition words. In this way, for example, it is possible to give an instruction in a short time for a highly urgent post.

  Further, the recognition word for posting may be more redundant than other recognition words. In this way, for example, when normal speech recognition is used, the possibility of saying another recognized phrase is reduced, and it is possible to prevent erroneous posting. The word "redundant" means that, for example, the number of characters is large and the number of characters is divided. In this way, for example, it is possible to reduce the possibility that a user who does not intend to post will erroneously speak.

  In addition, the recognition word for posting may be a phrase that is unlikely to be usually said by the user. In this way, for example, it is possible to prevent erroneous recognition from occurring frequently due to words frequently used in the vehicle by the user, and to prevent posting unintended by the user.

  When the recognition word for posting is recognized, the control unit 18 may output the voice of the character registered in advance in response to the recognition word, thereby realizing the interactive function as in the above embodiment. In this case, the voice of the character in the conversation for posting may be shorter than the voice in other conversations. By doing so, for example, the posting time can be quickly reduced by shortening the conversation time.

《Response phrase variation》
The response phrase of the character registered in advance in the database 19 can be in various modes as follows.
When the voice of the character prompting the selection of the searched facility is output with the content according to the displayed icon, it is a voice asking what number is better if it is a number, and what is the alphabet if it is an alphabet In the case of a shape, it may be a sound for inquiring what the shape is, and in the case of a color, it may be a sound for inquiring what the color is. In this way, the user can easily understand, for example, what to utter and select the facility.

  In addition, for example, the content corresponding to the displayed icon may be sound indicating the range of the selected candidate. Thus, for example, if the voice is output from what number to what number, the user can grasp not only the content to be uttered but also the range to be selected.

  As the voice of the character registered in advance, a voice indicating the status of the character may be inserted. In this way, the user can hear the character's situation.For example, if the character is in a negative situation, the user can be made to take care of the character, and if the character is in a positive situation, This can make the user feel the sympathy of the character.

  The statement indicating the status of the character may be, for example, a statement that indicates whether the user is in a positive state or a negative state, such as "I am busy." In this way, the system does not unconditionally follow the user's instructions, but can give the user a feeling of concern and empathy. It is good because it can be obtained.

  A plurality of lists may be set, and there may be a list in which phrases different from other phrases are registered even in the same list of response phrases. By doing so, for example, a foreign phrase is output as a response to the user's utterance having the same content, so that an unexpected impression can be given to the user. Can be prevented from coming. As a different phrase, for example, as shown in a ray response phrase 3 in FIG. 9A, “instruct something.”, “What to do?”, “What to do”, “how to change? It is advisable to insert an ambiguous phrase such as "Let's like." Also, as shown in the ray response phrase 24 in FIG. 9B, the phrases “re-search”, “re-search”, “one time”, and “re-do” are included in the phrase. You can insert a phrase that reads the psychology of the user, such as "You're trying me a lot?"

  A phrase to be output when speech recognition is incorrect may be registered. In this way, for example, even if the recognition is mistaken, the user can recognize that the conversation with the character is continuing by returning some phrase.

  It is preferable that a phrase to be used as an escape route in case an error occurs in voice recognition is registered. In this way, for example, there is a possibility that an error occurs in voice recognition, but even if an error occurs, the user's frustration and anger can be alleviated by the escape of the character.

  As the escape mouth, for example, as shown in the ray response phrase 1 of FIG. 8A, "I will do my best for speech recognition. I may not be able to recognize 100%." It is good to use an expression that indicates that achievement is difficult. By doing so, for example, it is preferable that a psychological level that can be accepted by the user with respect to erroneous recognition can be generated, rather than simply indicating that recognition is not possible.

  When there is a user's voice input indicating that the content that the user desires to reply and the content of the character's voice output are different, it is preferable that a response phrase from the character is registered in response to the user's voice input. . In this way, for example, when the user points out a mistake in the character, the character responds to the mistake, so that when the misunderstanding is misunderstood, it is possible to enjoy the natural exchange between the people.

  It is good that a phrase to be used as a promotion advertisement is registered. In this way, for example, the user can be guided to the affiliated facility. For example, the phrase may be an invitation to a specific facility, such as "How about a XX shop?"

  It is preferable that a phrase about the cause of the user performing at the destination facility be registered. In this way, the user who goes to the facility can easily listen to the cause by speaking about the cause of the decision to go to the facility. For example, the user's attention can be drawn whether the cause of the destination is unfavorable to the user or to the user.

  The facility that causes the destination to be unfavorable to the user may be, for example, a facility related to the user's illness, such as “hospital”, “dentist”, or “pharmacy”. As a facility that is preferable to the user for the cause of going to the destination, for example, a facility such as “department store”, “sushi”, and “eel” which has a slightly higher hurdle than a facility that is frequently visited may be used.

  As a phrase that causes the character to cause various emotions to the user, for example, as shown in a response phrase 6-8 in FIG. 9C, “hospital? Do not overdo it. " Also, for example, as shown in a response phrase 6-29 in FIG. 9D, a phrase that causes the user to regret, such as "Do you brush your teeth properly?"

  It is preferable that a phrase serving as a positive or a negative advice on what to do at the facility where the user is to go is registered. In this way, for example, the user can determine what to do or not to do at the destination based on the advice of the character. As a positive advice, for example, as shown in a response phrase 6-29 in FIG. 9D, a phrase that recommends something, such as "It is better to have plaque occasionally." Good. In addition, as negative advice, for example, as shown in the response phrase 6-23 in FIG. 9E, "the face should not be painful. It is a man who can endure with a cool face." Should be a phrase that prohibits something.

  It is preferable that a phrase that is a one-sided impression of the character about what the user does at the destination facility be registered. In this way, for example, the impression of the character can be obtained, so that the user can refer to the action at the destination.

  As the one-sided impression of the character, for example, as shown in the response phrase 6-14 in FIG. 9 (f), a positive affirmation such as “black pig char siu that melts in your mouth. It should be an impression. In this way, the user may want to take a similar action at the facility. In addition, for example, a negative impression such as “Do you go to a restaurant alone? Do you feel lonely? In this way, the user is encouraged to change the destination. Further, for example, as shown in a response phrase 6-21 in FIG. 9G, a positive impression and a negative impression such as “It seems to be fun just to look around the shopping mall. Impressions may be mixed. In this way, the user can be prepared for the situation at the destination in advance.

  A phrase that suggests that the character actually exists may be registered. In this way, for example, the user may have a feeling that the character actually exists.

  As a phrase reminiscent of existence in reality, for example, as shown in a response phrase 6-24 in FIG. 9 (h), "I am glad to take me on a business trip." As shown in the response phrase 6-25 of 9 (i), the phrase may be a phrase reminiscent of being accompanied, such as "Where are we staying?" In this way, for example, the user may have a feeling of being always with the character.

  It is preferable that voice data output by the character is registered when a voice other than a phrase set in advance as a recognized phrase is input. In this way, for example, even if it is other than a recognized phrase, there is always a reaction of the character, so that the dialogue is interrupted or an error is reported to the user, so that the user is reminded of the exchange with the system. It is good because you can maintain the feeling of continuing the dialogue with the character. As a phrase when a voice other than the set phrase is input, a phrase that cannot be recognized, such as a ray response phrase 50 in FIG. 9J, can be considered. Note that the response phrase is not limited to a mode in which the response phrase is randomly output from a plurality. The order of output is determined from among multiple items, and they are output sequentially in that order. When the last response phrase is output, return to the first response phrase and output it. It is possible to prevent the phrase from being output. Furthermore, the corresponding response phrase may be determined for each recognition phrase on a one-to-one basis. By doing so, the storage amount of information can be saved. Even in such a case, the same effect can be obtained if the response phrase having the content described above is set.

《Timing of voice output and voice recognition》
Various settings can be made for the timing of voice output and voice recognition as follows.
The control unit 18 may stop the voice recognition while the voice of the character is being output until the voice is completely output. In this way, for example, when a voice is input from the user in the middle of the voice of the character, another process may be prevented from being executed by voice recognition. Other processing may be low urgent processing, such as volume, brightness, scale, and peripheral search. In this way, it is not necessary to execute by voice recognition even if it does not necessarily have to be executed immediately.

  The control unit 18 may receive voice recognition while the voice of the character is being output. With this configuration, for example, when a voice is input from the user in the middle of the voice of the character, other processes than the voice recognition need not be interrupted. As another process, for example, a process with a high degree of urgency, such as a process of transmitting position information on a control place to an information collection server, may be used. In this way, the processing that the user wants to execute immediately does not have to be interrupted.

  The control unit 18 may stop outputting the voice of the character when a voice is input from the user while the voice of the character is being output. In this way, for example, the voice of the user can give an impression that the remark of the character is interrupted. If the output of the voice of the stopped character is not output again, for example, the same utterance does not have to be repeated from the beginning to give an unnatural impression. If the output of the sound of the stopped character is started, for example, from the point where the sound is stopped, it may be possible to give the impression that the character has been waiting during the speech of the user.

  The control unit 18 may stop the sound of the character when a predetermined input operation is performed while the sound of the character is being output. In this way, the voice of the character may be stopped by a predetermined input operation, for example, when the third party does not want to hear the conversation with the character. The predetermined input operation may be, for example, an operation of a physical key. With this configuration, it is sufficient to always operate a fixedly existing portion, so that a quick operation can be easily performed.

《Timing of voice recognition activation》
As for the timing of voice recognition activation, various modes are possible as follows.
The control unit 18 may start a predetermined process for outputting information desired by the user in response to the dialogue by inputting a voice from the user corresponding to the predetermined recognition word. With this configuration, for example, since the predetermined process is started when a voice is input from the user, the system does not need to be started and the process is not executed.

  The control unit 18 performs a predetermined process for outputting information that the user wants to know in response to the dialogue, and outputs a voice of a predetermined character in response to a voice input from the user corresponding to a predetermined recognition phrase. May start. With this configuration, for example, the output of the voice of the character triggers the user to determine whether or not to start the predetermined process, so that the opportunity to use the system can be increased.

  The output of the voice of the character may be, for example, an inquiry as to whether or not a specific process has started. By doing so, for example, the user may be prompted to use the processing. If the timing of outputting the voice of the character is, for example, regular, the frequency of using the process may be increased. Further, if the timing satisfies a predetermined condition, the user can be encouraged to use the process at a timing suitable for using the process.

《Other》
As a mode in which the icons indicating the surrounding facilities are relatively highlighted as compared with the map, it is preferable that the icons indicate the positions of the facilities. For example, if at least one of the brightness, the saturation, and the hue of the icon and the map is changed, the contrast between the two may be noticeable.

  When an icon indicating the surrounding facility is displayed so that the order according to a predetermined criterion can be distinguished, the predetermined criterion may be, for example, the order of importance to the user. In this way, the facility that the user wants to know most may be preferentially displayed. The importance for the user may be, for example, that the user has performed in the past, that the user has performed frequently in the past, or that the user's preference is met. In this way, the user can quickly know the facility he wants to go to. In addition, for example, those that have been performed in the past but do not want to go again and may be excluded from the importance of the user may be excluded. In this way, for example, only items that the user may go to may be displayed.

  The display in which the order can be distinguished may be information that visually indicates the order, for example, a shape such as ◎, △, Δ, or ×, or a stepwise change depending on brightness, saturation, or hue. In this way, for example, the order can be visually and intuitively grasped.

  When recognizing the voice of the user selecting one of the facilities with the content corresponding to the displayed icon, for example, the alphabet is the alphabet of the desired facility icon, and the shape is the desired facility icon shape , The color of the icon of the desired facility may be used. Even in this case, the facility can be selected with a word that is easier to remember than the facility name.

  In the display area of the item displayed by the button, the portion where the image behind can be seen may be, for example, a transparent portion. By doing so, for example, the background image can be seen better while ensuring the visibility of the item display.

  Some recognition words registered in advance for recognizing the user's voice may be displayed on the display screen, and some may not be displayed on the display screen. In this way, for example, even if the user utters a word that is not displayed on the display screen, if the recognition word is a preset recognition word, a certain reaction from the character can be obtained. It can be a surprise for the user and give the user the joy of discovery.

  Descriptive words corresponding to the functions that change quantitatively as recognition words and numbers indicating the quantitative level include, for example, "Onryo-san", "Kidoni", "Skeel Nikuro", The name and the quantitative level may be combined into one recognition phrase. In this way, the utterance only needs to be performed once.

  The button for displaying the instruction word corresponding to the function may include a button for executing the function without transiting to another display screen. With this configuration, for example, the function can be executed through the dialogue without transiting to another display screen to execute the function, so that the current screen display does not need to be disturbed.

  In the present embodiment, an example of the navigation device has been described, but the present invention can be implemented as a function of various electronic devices. For example, it may be incorporated as a function of a radar detector, a drive recorder, and a car audio. In addition, the value of the quantitative level, the screen size of the display unit 5, various time settings, and the like described in the present embodiment can be arbitrarily set as long as the effects of the present invention are achieved. The control unit 18 has a function of setting the priority of each function or alarm based on an instruction from the user from the remote controller 17 or the like, so that the control unit 18 performs processing with the set priority. You may comprise.

  Further, in the above-described embodiment, the apparatus is provided with the database 19 storing various kinds of information, and the control unit 18 accesses the database 19 to read out necessary information and performs various kinds of processing. It is not limited to. For example, part or all of the information registered in the database 19 is registered in the server. The navigation device, the radar detector, and other electronic devices / devices have a function of communicating with the server, and the control unit 18 may appropriately access the server, acquire necessary information, and execute processing. Good. Further, at least a part of the functions of the control unit 18 may be set in a server, the functions may be executed by the server, and the electronic device owned by the user may be configured to obtain the execution result.

  The function as the control system of the above-described embodiment is configured as a program to be realized by a computer provided in the control unit 18. However, the present invention is not limited to this, and the program is distributed to a plurality of computers and distributed processing is performed. Is also good.
