Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention provides an environment in which various information existing on a network or a database can be obtained without using a user's gaze at an operation display screen by using a response function using a voice output by a synthetic voice or the like. And a method for accessing information using voice.
[0002]
[Prior art]
With the rapid progress of computer technology in recent years, the environment in which various information existing on a network or a database can be freely accessed, and required information can be obtained or browsed has been developed in various forms. Are provided. In the future, as access devices for information in such an environment become smaller, more mobile, or more wearable, it is necessary for the user to constantly watch the display screen for operating the access device for information when using the device. It is predicted that the number of situations where the user wants to relax the constraints tends to increase. For example, information access through a mobile phone, information access through an in-car terminal, and the like are considered as such scenes.
[0003]
For example, as an example of information access by a mobile phone, an information providing service such as an “i-mode” (R) service provided by NTT DOCOMO is given. In such an information providing service, an access operation is basically performed while looking at a screen.
[0004]
However, for example, when assuming the use of the service while walking, or the use of an information extraction service using guidance by voice output, the data reading operation by voice response is more effective than the screen operation. There is a possibility that high convenience can be exhibited, and it is considered that the need for such a voice operation interface will increase in the future.
[0005]
On the other hand, regarding information access devices for automobiles, the use environment of car navigation systems (hereinafter referred to as “car navigation systems”) has been deeply penetrating into the general passenger car world, especially in Japan. An environment has been realized in which various information such as detailed electronic maps and traffic information, as well as information on facilities near the current location can be obtained or browsed.
[0006]
In the future, with the further development of car navigation systems, automobiles will be transformed into “running information stations”, and the need for on-board information browser devices is expected to grow rapidly. It is expected that the convenience or comfort of automobiles, whose value has been the main means, will dramatically increase.
[0007]
However, when such an information access device is brought into a vehicle, the convenience is improved, but on the other hand, complicated device operations for browsing information and subtasks such as watching the information itself occur, so traveling It is feared that the driver inside will be devoted to the main task of "driving", which may have an adverse effect or load. It has also been pointed out that an increase in the load on the sub-tasks other than the driving frequently causes inattentive behavior, distraction, and the like, resulting in a high possibility of causing a rear-end collision, a collision accident, and the like.
[0008]
In order to solve such a problem, a voice interaction system disclosed in (Patent Document 1) that realizes all dialogs with an information access device to be operated by voice input / output, As disclosed in 2), many voice interaction systems using physical devices such as buttons in addition to voice input / output have been developed.

[0011]
[Problems to be solved by the invention]
However, in an information access apparatus corresponding to a user's voice input as disclosed in (Patent Literature 1), a noise in a real environment represented by a road noise or the like is generated particularly for a voice recognition engine constituting an input system. There are many technical issues to be overcome, such as the problem of recognition errors due to the problem and the ambiguity of voice input contents for unknown menu items, and the introduction of the voice input function has reduced convenience. However, there is a possibility that a problem that the psychological load is increased as a result may occur.
[0012]
Also, in addition to voice (recognition) input typified by an IVR (Interactive Voice Response) using a fixed / mobile phone, a menu item number or the like is specified via a physical device such as a push button on the phone. Although an information access device is also conceivable (Patent Document 2), in this case too, if the number of menu items read out aloud is too large, it cannot be memorized in the head. Even if you want to hear back, voice guidance flows. If the item name is too short, the contents will be difficult to understand if the item name is too short, etc., causing problems specific to the audio data stream, and may increase the psychological load caused by the operation for the user. Is also left. As a result, for example, there is a problem that a driver who is driving a car may be distracted and fall into a dangerous situation.
[0013]
The present invention has been made in order to solve the above-described problems. In order to solve the above problems, even when the user does not gaze at the display screen for the operation, or even when the user cannot do so, the information access using the voice that can perform the information access operation easily and quickly It is an object to provide an apparatus and a method.
[0014]

It is characterized by the following.
[0020]

It is possible to provide an information access apparatus using voice that can perform a highly comfortable information access operation.
[0021]
BEST MODE FOR CARRYING OUT THE INVENTION
(Embodiment 1)
Hereinafter, an information access device using voice according to the first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of an information access device using voice according to the first embodiment of the present invention.
[0022]
In FIG. 1, reference numeral 11 denotes a user input receiving unit that receives an input operation by a user, 12 denotes a presentation information management unit that determines information content to be presented according to a user input, and 13 denotes a user to the determined user. The voice response processing unit 14 transmits the information content to be transmitted to the user via voice output. The user 14 actively controls the order, flow, level of detail, etc. of the information content via the voice output presented to the user. , The voice response behavior control units that can be changed are shown. Reference numeral 15 denotes a physical device to which a user can input an arbitrary instruction.
[0023]
The user input receiving unit 11 has at least a speech recognition engine for accepting a speech input by the user and using the speech input as search key information of information content to be presented, and a speech recognition result by the speech recognition engine. To the presentation information management unit 12 as key information.
[0024]
In the presentation information management unit 12, the menu configuration or content to be displayed to the user is stored in the display information database 16 in advance, and based on the key information passed from the user input reception unit 11, the display information database 16 is displayed. To determine the information content to be displayed to the user.
[0025]
The voice response processing unit 13 outputs the information content to be presented to the user determined by the presentation information management unit 12 by using a synthesized voice or the like. The user can determine whether the determined information content is the information desired by listening to the content of the output voice.
[0026]
Then, the voice response behavior control unit 14 adds an additional condition to the key information to be passed to the presentation information management unit 12, An instruction to change the setting conditions such as the reproduction output speed in the response processing unit 13 is issued.
[0027]
2 and 3 are configuration diagrams of the voice response behavior control unit 14 in the information access device using voice according to the first embodiment of the present invention. 2 and 3, description will be made on the assumption that a device 21 which is a button for switching the operation mode of the device 22 and a device 22 which is a dial remote controller are used. Of course, it is not limited to this embodiment.
[0028]
First, FIG. 2 is a configuration diagram of the voice response behavior control unit 14 for adjusting the reading speed. In FIG. 2, the operation mode determination unit 141 uses an input signal from the device 22 based on whether the input from the device 21 is an ON signal or an OFF signal to change the information content to be presented. Or a signal for changing the reading speed is determined.
[0029]
Then, based on the determined operation mode, the instruction command generator 142 generates an instruction command corresponding to each mode. That is, in a mode in which the information content to be presented is changed, key information for extracting the information content from the display information database 16 is generated. In a mode in which the reading speed is changed, the reading speed parameter is used. The adjustment unit 143 changes the parameter for adjusting the reading speed.
[0030]
Next, FIG. 3 is a configuration diagram of the voice response behavior control unit 14 for adjusting the level of detail of the name of the reading item (the length of the text that conveys information contained in the item). As shown in FIG. 3, the basic configuration is the same as that of FIG. 2, but the operation mode determining unit 141 determines whether the input from the device 21 is an ON signal or an OFF signal, Is different in that the operation mode is determined whether the input signal from is a signal for changing the information content to be presented or a signal for changing the detail level of the reading item name.
[0031]
Then, based on the determined operation mode, the instruction command generator 142 generates an instruction command corresponding to each mode. That is, when the mode is a mode for changing the information content to be presented, key information for extracting the information content from the display information database 16 is generated, and when the mode for changing the detail level of the reading item name is used. Thus, the parameter for adjusting the reading detail level in the reading detail level adjusting unit 144 is changed. In this case, it is needless to say that the information content corresponding to the detail level needs to be stored in the display information database 16 in advance.
[0032]
With the above-described configuration, the menu item in the voice response (speech) is the information desired by the user as compared with the normal IVR system in which the item number of the voice menu is simply input and designated by the telephone push button. If it is determined that the item is unrelated to the item, the user can quickly move to the next menu item based on the user's intention, or if the information content is missed during the voice response (reading), When it becomes necessary to refer to the previous menu item again, it is possible to move to the desired menu item without waiting for the end of the voice response.
[0033]
Therefore, it is not necessary to continuously listen to the voice response until the menu item corresponding to the information content desired by the user appears, or even if the number of candidate menu items is large, all the contents are individually There is no need to temporarily store the item numbers in association with the item numbers.
[0034]
In addition, even when the contents of the menu item cannot be grasped during the voice response (speech), the detail level of the item name (the length of the text that conveys the information content included in the item) can be increased.
[0035]
In this way, since the conscious or psychological burden spent by the task of operating the information access device can be minimized, access to the target information can be performed while maintaining a safer and more secure state. It is possible to do.
[0036]
On the other hand, if an error occurs in the via menu item due to the voice recognition result error during the reading confirmation, and the user confirms the error, the menu selection is performed via the device connected to the voice response behavior control unit 14. It is also conceivable to change the item and perform a return operation to the intended correct menu item.
[0037]
For example, for a menu hierarchy configuration of “gourmet” → “French cuisine” → “XX restaurant”, an attempt is made to directly move (shortcut) to a menu item “XX restaurant” existing in a lower hierarchy by voice input. In doing so, the voice response processing unit 13 sequentially reads out the menu item names that pass through to the menu item to be displayed for each layer, and moves through the layers while receiving a confirmation operation by the user. become.
[0038]
At this time, if the target item is erroneously recognized as “gourmet” → “Italian food” → “△△ shop” due to occurrence of a voice input error or the like, check the item of “Italian food” on the second level. If the user notices that misrecognition has occurred at the stage of performing the operation, the device 15 connected to the voice response behavior control unit 14 is operated to immediately move to the intended correct item “French cuisine”. It can be so. Specifically, by rotating the dial remote controller as the device 22, the items located in the same hierarchy are output as audio.
[0039]
With such a configuration, even when an input error due to voice recognition occurs, it is possible to perform a return operation to the menu item intended by the user in relatively few steps.
[0040]
As the device 15 connected to the voice response behavior control unit 14, it is conceivable to use a device in which each function for behavior operation is assigned to a push button, as generally used in an IVR system. . However, the present invention is not particularly limited to this. For example, it is also conceivable to use a dial-type remote controller that can be operated without releasing the hand from the steering wheel, to which various functions for behavior operation are assigned. . In the latter case, it is conceivable to read the rotational speed of the dial feed / return operation and change the magnitude of the movement step amount of the menu item according to the magnitude of the speed. In the case where the position (order) of selection items to be specified for a known menu configuration can be estimated in advance, unnecessary voice responses can be skipped quickly, so that menu operations can be performed in a shorter time. It becomes possible.
[0041]
As a specific operation method, as shown in FIG. 4, when the dial is rotated by one step in the forward direction (1), an information menu item to be output as an audio is forwarded to the next. When the dial is rotated in the opposite direction ((2)), the information menu item to be output as sound is returned to the next one. When the dial is pressed in the dial radial direction (3), the detail level is set higher than the detailed level indicating the information content. When the dial is pressed in the opposite dial radial direction (4), the information level is increased. The detail level may be lower than the detail level indicating the content.
[0042]
As for the usage of the mode button, when the mode button is OFF, the respective functions are assigned to the operations (1) to (4) as described above. On the other hand, when the mode button is ON, when the dial is rotated by one step in the forward direction (1), the detail level of the information content to be presented is increased (for example, a longer item name text is output by voice). Also, when the dial is turned in the opposite direction (2), the level of detail of the information content to be presented may be lowered (for example, a shorter item name text is output as voice).
[0043]
On the other hand, as the device 15 connected to the voice response behavior control unit 14, a push button or a cursor of a mobile phone may be used instead of the dial-type remote controller. In this case, to the function buttons other than the number buttons of the mobile phone, various functions such as the above-described sending process and returning process for the audio output of the menu item or changing the detail level of the information content are assigned.
[0044]
In the first embodiment, the menu selection-based operation interface is described. However, the present invention is not limited to this. For example, an operation of a web browser that sequentially refers to web information while following a link Applicable to interfaces.
[0045]
Next, a description will be given of a processing flow of a program for realizing the information access device using voice according to the first embodiment of the present invention. FIG. 5 shows a flow chart of a process of a program for realizing the information access device using voice according to the first embodiment of the present invention.
[0046]
In FIG. 5, first, a voice input by a user is received (step S501), and voice recognition for the input voice is performed using a voice recognition engine (step S502).
[0047]
Next, the display information database 16 in which the menu configuration or the content to be displayed to the user is stored is queried using the recognition result as key information (step S503). Then, the information content to be displayed to the user is extracted from the display information database 16 (step S504).
[0048]
Next, the extracted information content to be presented to the user is output as a voice using a synthesized voice or the like (step S505). Then, an operation signal using the external device by the user who has heard the output voice is received (step S506).
[0049]
If the operation signal is a key information update instruction, the key information is re-created (step S507), and the process returns to step S503. If the operation signal is an instruction to change the playback output speed in the voice response, the speed parameter in the playback output is updated (step S508), and the process returns to step S505.
[0050]
As described above, according to the first embodiment, it is possible to easily and reliably update the content of the voice response processing using the external device. Therefore, when the voice data stream is used, the redundancy and the difficulty of the search are reduced. It is possible to overcome it.
[0051]
(Embodiment 2)
Hereinafter, an information access device using voice according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 6 shows a configuration diagram of an information access device using voice according to the second embodiment of the present invention.
[0052]
As shown in FIG. 6, although the configuration itself is not significantly different from that of the first embodiment, for example, a user who estimates a visual or conscious load state spent on driving operation by a driver while driving and outputs the load level It is characterized in that a load status estimating unit 61 is provided.
[0053]
That is, when the driver is going to change lanes, it is necessary to continuously watch the following vehicle. Alternatively, when trying to make a right turn inside an intersection, attention must be paid to pedestrians and straight-ahead vehicles. The user load situation estimating unit 61 preliminarily estimates a case in which the driver, who is the user, considers that the load level for the driving operation is in a relatively high state, such as a case where the user is traveling on an unguided route while being lost. , For the menu items or the presented information contents, such as setting the reading speed to a lower speed.
[0054]
Alternatively, it is conceivable to change the reading order of the information content itself in consideration of the load on the user when presenting the information content. For example, information with a high load at the time of browsing, such as inducing mental arithmetic processing, is read backward, and is presented when it is determined that the driving load has become low.
[0055]
Further, when it is estimated that the state where the driving load is high continues, it is conceivable to lower the presentation detail level of the information content and read it as a more concise information content.
[0056]
As described above, by estimating the load situation of the user, by changing the voice response behavior according to the estimated situation, when the driver cannot actively operate the voice response behavior for some reason, or when the driver does not operate the voice response behavior, In addition, it is possible to suppress the conscious attention spent on the operation for accessing the information, and to execute the target information access operation while maintaining a safer driving state.
[0057]
In order to estimate the load status of the user in this way, various sensors are required. For example, assuming an in-vehicle information access device operated by a driver while driving, in order to estimate the user's load situation, a small camera installed inside the vehicle (such as a rearview mirror or a dashboard) is used to estimate the load on the driver's head. It is conceivable to add a function of tracking an operation by image processing.
[0058]
If the average amount of head movement or the number of operations per unit time observed by such a small camera or the like becomes larger than the normal state, it is determined that the driving load state of the driver is high, and the voice synthesis function is used. Can be used as an index for controlling
[0059]
Further, as another configuration of the user load status estimating unit 61, the operation amounts of various operation devices for controlling the vehicle state such as the steering wheel, the accelerator, and the brake are measured, and a curve is formed based on the measured values. It is also conceivable to estimate a load state such as running on a continuous mountain road.
[0060]
In addition, a configuration is also conceivable in which the user's load situation is estimated based on an external situation such as a geographical factor or a traffic jam without providing a sensor device such as a small camera. As an example, assuming an in-vehicle information access device operated by a driver while driving, information on the current position of a vehicle and a traveling road is received based on GPS or map information as in a current car navigation system, Based on information on roads, for example, when traveling on a mountain road with many curves, in front of a main station, or on a highly congested road in an urban area, it is estimated that the driving load of the user is large, and the listening load is reduced. Is to change the behavior of the voice response so as to reduce the response.
[0061]
However, in this case, there is a possibility that the voice response control is executed contrary to the user's own intention and desire. In such a case, the user himself / herself performs the voice response control via the device 15. By changing the behavior, the inconsistency between the behavior of the system and the user's feeling can be easily and immediately corrected.
[0062]
Next, a description will be given of a processing flow of a program for realizing the information access device using voice according to the embodiment of the present invention. FIG. 7 shows a flowchart of the processing of a program for realizing the information access apparatus using voice according to the embodiment of the present invention.
[0063]
7, first, a voice input by a user is received (step S701), and voice recognition is performed on the input voice using a voice recognition engine to generate key information of the display information database 16 (step S702).
[0064]
On the other hand, detection signals from various sensors are received, and the load status of the user is estimated (step S703). Then, the generated key information is updated according to the estimated load condition (step S704), and the display information database 16 is queried based on the updated key information (step S705) and displayed to the user. The information content to be extracted is extracted (step S706).
[0065]
Then, the extracted information content to be presented to the user is output as a voice using a synthesized voice or the like (step S707), and an operation signal using the external device by the user who has heard the output voice is received (step S707). S708) makes it possible to more directly access information desired by the user. The following processing is the same as in the first embodiment.
[0066]
As described above, according to the second embodiment, it is possible to estimate the user's load situation in advance, and then to present the information content corresponding thereto, and to present the information content that does not meet the user's intention. However, it is possible to easily update the presentation content.
[0067]
