Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device capable of conversation between a plurality of users and a processing system equipped with the communication terminal device.

[0002]

2. Description of the Related Art Recognizing conversational voice, displaying keyword candidates suitable for information retrieval, performing a search with a keyword selected by a user from the keyword candidates, A technique relating to a telephone terminal device for displaying a search result is disclosed in Japanese Patent Laid-Open No. 11-25228.
It is disclosed in Japanese Patent Publication No. According to this technique, information can be searched for by a simple operation even while having a conversation. In other words, even if the user does not input the keyword necessary for information retrieval from the beginning, the user recognizes the conversation voice and automatically displays the candidates, so that the user “selects” the desired one from the candidates. All you have to do is

However, in this conventional technique, only the user who uses the telephone terminal device that has performed the search can directly know the search result. In other words, it is inconvenient for the conversation partner to be verbally communicated by the user who directly knows the search result. That is, it is necessary to perform a transmission operation of transmitting the information retrieval result to the other party. After the oral communication, the result of the information retrieval will be known to all the conversants, so that the conversation will return to a natural conversation again, but the natural communication is interrupted at the oral communication part. Not preferable. Further, since it takes a form of indirect information transmission, that is, a message, it is not preferable in terms of accurate information transmission.

Therefore, it is an object of the present invention to allow a result of a search based on a keyword extracted by recognizing a conversational voice to be shared by all the conversants without requiring a special intermediary action of the user.

[0005]

Means for Solving the Problems and Effects of the Invention
According to the described communication terminal device, by recognizing the voice of the conversation between a plurality of users and outputting the result of the information search using the recognition result via the voice output means, the device itself. The user of the other communication terminal device can also be notified by transmitting the information to another communication terminal device via the communication means. By doing so, "one user conveys the result of the information search to the other side", which was performed in the conventional technique.
The transmission operation is not required. In other words, the result of searching based on the keyword extracted by recognizing the conversation voice can be shared by all the conversants without requiring any special intermediary action of the user. Therefore, it is possible for both parties in a conversation to feel as if another user was speaking, and it is possible to create a situation in which a three-party call is being made. Of course, when the conversation is originally made by three or more persons, it becomes a situation in which another user speaks, and a natural conversation can be continued.

Further, according to the communication terminal device of the second aspect, since the user automatically retrieves information without performing any special operation, for example, when talking on the telephone while driving a car. Is effective for. For example, hands-free calling is effective for safety during driving, but if such a manual operation by the user as in the prior art is required for information retrieval, the effect of making hands-free is reduced. It Therefore, by automatically outputting the information retrieval result, it is possible to obtain the merit of ensuring safety during driving of the vehicle. In particular, in the case of the conventional technique, the search keyword candidates are displayed to be specified by the user, but it is not preferable to create a situation where the driver must look aside while driving the vehicle. Therefore, also from this point of view, it is effective to employ a method of notifying the search result by voice without requiring user operation.

Further, according to the communication terminal device of the third aspect, it is possible to retrieve information by excluding the keyword that is not suitable from the context. Therefore, the inappropriate keyword obtained by erroneous recognition is used for the information retrieval as it is. Can be prevented. Also, since it is a conversation, the topic often changes. In that case, the keyword recognized before the topic change is
Even if they are correctly recognized rather than erroneously recognized, they are not appropriate as keywords for information retrieval. Therefore, as described in claim 4, it is possible to provide an appropriate search result by not using the keyword before the topic change in the information search.

On the other hand, regarding the retrieval result, rather than suddenly unilaterally outputting detailed contents by voice, as shown in claim 5, first ask the user whether or not to output the detailed result. It is possible to This kind of setup is more like a natural conversation.

The database for which information is to be searched may be stored in the device itself, as a matter of course.
As described above, if an external database is accessed via the Internet or the like, it is possible to search using a wider range of information resources. By the way, such a communication terminal device and a processing device (for example, a navigation device) that executes a predetermined process may be provided so that the user can instruct the processing by the processing device using the search result. For example, when "place name-related data" such as a place name or a store name is obtained as a search result, it is convenient if the navigation device can be used as a destination for route search or a map including the store can be displayed. Is. For example, let us consider a case where communication terminal devices used by both parties having a conversation configure the same processing system and are both mounted in a vehicle. In the case of gathering at a certain store due to the flow of conversation, if either one of the talkers indicates the route search as the destination, the route search is performed by the navigation devices mounted on both vehicles. By doing so, the route to the meeting place agreed with each other can be easily searched, and the usability is greatly improved.

For example, if the processing device is a navigation device, a place name (address) having a hierarchical structure may be input by voice to set a destination and the like, and naturally various functions of the navigation device are used. Command to specify. If this navigation system is assumed, by executing the recognition process described above, it is possible to immediately respond not only to the input of the place name (address) but also to the input of the command. It is not necessary to separately perform the recognition process using. That is, the response is improved and the usability for the user is improved. Further, even in the case of the map display, if both of the distant talkers can see the same map screen, the conversation becomes easy.

And can communicate data with. The audio output device 6b is for outputting audio through a speaker, and the display device 6c is for displaying a screen on a display.

In the present embodiment, the microphone provided in the voice input device 4 is installed in a place where the voice emitted by the user who is driving the vehicle can be reliably collected, while the speaker provided in the voice output device 6b. Is installed in a place where the user who is driving the vehicle can reliably listen to the sound output from the speaker. Therefore, the communication device 6a
Even when a mobile phone is used as described above, a "hands-free call" is possible in which the user makes a call without holding the mobile phone by hand. In other words, the mobile phone has a general configuration including an antenna for transmitting and receiving radio waves to and from the base station, a microphone, a speaker, a group of operation keys (none of which is shown), and so on. Makes a call using the above-mentioned microphone and speaker. However, when using a mobile phone, the mobile phone can be controlled by the control device 5 via the mobile phone connection device because the mobile phone connection device is used to connect to the control device 5. As a result, as described above, a call using the speaker and the microphone included in the processing system 1 is possible without using the speaker and the microphone included in the mobile phone. When the mobile phone receives an incoming call, the incoming call is made according to the incoming call operation by the user. The incoming call operation is, for example, operation of a predetermined switch (incoming call switch) in the operation switch group 3a, or the user uttering a predetermined word (for example, “hi”) from the voice input device 4, The voice recognition unit 5c in the control device 5 recognizes it, and the data processing unit 5d
You may make it correspondent process.

The external storage device 7 has an external data input device 7a and an external storage medium 7b, and outputs various data read from the external storage medium 7b to the control device 5 using the external data input device 7a. To do. This external storage medium 7

On the other hand, the control device 5 includes a CPU, a ROM, and an R.
It is mainly composed of a well-known microcomputer composed of AM and controls the entire system. Control device 5
Is a position data input unit 5a, an operation input detection unit 5b,
The voice recognition unit 5c, the data processing unit 5d, the output method selection unit 5e, the search data storage unit 5f, and the keyword / grammar data storage unit 5g are provided.

The position data input section 5a is used for the GPS receiver 2
a, data (position data) from the gyroscope 2b and the vehicle speed sensor 2c are input. The input position data is sent to the data processing unit 5d. Data processing unit 5d
Then, the present location is specified (calculated) based on the position data and the map data acquired from the external storage medium 7b via the external data input device 7a.

The operation input detection section 5b includes an operation switch group 3
The operation input made by the user is detected from a and the remote control sensor 3b and output to the voice recognition unit 5c and the data processing unit 5d. The voice recognition unit 5c extracts conversation voice data from the voice input via the voice input device 4. Then, the extracted conversational voice data is collated by referring to the dictionary data stored in the keyword / grammar data storage unit 5g, and compared with a plurality of comparison target pattern candidates, the higher comparison target having a higher degree of matching is compared. Get the pattern.

Note that voice recognition is not always performed.
When the ambient stationary noise level is detected and it is detected that the conversational voice is added to the stationary noise, or when the recognition input instruction operation of the user via the operation device 3 is detected by the operation input detection unit 5b. Run. Since the signal input from the user via the voice input device 4 is a mixture of not only the conversational speech to be recognized but also noise, the voice section and the noise section are determined. As this determination method, many methods have been proposed in the past, for example, by extracting the short-time power of the input signal at regular time intervals, and determining whether the short-time power of a predetermined threshold value or more has continued for a certain time or more. A method of determining whether it is a voice section or a noise section is often adopted. In addition, the recognition of a word sequence in the input speech is performed by sequentially acoustically analyzing the extracted conversational voice data to extract an acoustic feature amount (for example, cepstrum), and the acoustic feature amount time-series data obtained by this acoustic analysis. To get Then, the well-known HMM (Hidden Markov Model), D
The time-series data is divided into some sections by the P matching method or neural network, and each section corresponds to which word stored as dictionary data.

Then, with respect to the recognition result obtained in this way, context determination is performed as necessary, an appropriate keyword is determined, and the keyword is sent to the data processing unit 5d. The context determination will be described later. In addition to the above-mentioned current location identification, the data processing unit 5d searches for an optimum route from the current location to the destination, provides route guidance based on the searched route, and displays a map including the designated point. Perform navigation-related processing. Further, it also performs a process of performing an information search based on the keyword recognized by the voice recognition unit 5c and outputting the search result by voice. The data processing unit 5d performs the necessary output by the output device 6 selected via the output method selection unit 5e so that the output method according to the processing is performed.

The search data storage unit 5f has an internal storage medium, and stores the result of information search performed by the data processing unit 5d. Then, the data processing unit 5d outputs the search result as a voice from the voice output device 6b at a specific timing during the conversation, and also transmits it to another communication device via the communication device 6a. The guidance route obtained as a result of the route search by the data processing unit 5d is also stored here. Then, in the route guidance, the route route displayed on the display device 6c is highlighted by superimposing the guidance route on the road data, and based on the current location specified by the data processing unit 5d, the direction of travel of the route and the like are displayed by the voice output device 6b. Provide voice guidance.

Next, regarding the operation of the processing system 1 according to the present embodiment, particularly, the information retrieval is performed based on the keyword in the conversation, and the retrieval result is provided to the conversation user by voice. Explained. As shown in the flowchart of FIG. 2, noise learning is performed in the first step S1. This measures the steady noise level in the voice recognition unit 5c based on the voice input by the voice input device 4. Then, in subsequent S2, it is determined whether or not there is a trigger indicating the start of conversational voice input, and if there is a trigger (S2: YES), voice recognition is performed (S2).
3). Note that, as described above, "when there is a trigger" means that, when it is detected that conversational voice is added to stationary noise, or when a recognition start instruction operation is performed by the user via the operation device 3, the operation input detection unit This is the case when detected in 5b.

Following the voice recognition in S3, keyword extraction is performed in S4. This is to obtain a plurality of keywords as a recognition result while referring to the recognition vocabulary database stored in the keyword / grammar data storage unit 5g for the continuously input conversation voice.

Here, the two parties will be further described by taking the following conversation as an example. A1: "By the way, I'm hungry. What should I eat?" B1: "Hmm, I hope it's light." A2: "I think Japanese food or not." B2: "I like udon or soba." A3 : "Do you know any good point in Matsumoto city?" When extracting keywords in S4, due to sudden noise and vocalist's habit, for example, from the utterance content of A2 above, incorrect keywords such as "Java" and "flower arrangement" were selected. To detect,
There is a possibility that the keyword “Sora” may be erroneously detected from the utterance content of B2. Therefore, in the subsequent S5, context determination is performed, and it is determined whether the keyword is valid (whether appropriate) based on the determination result (S6). Only when the keyword is valid (S6: YES), the search It is added to the keyword string (S7), and the data search process is executed (S8). Specifically, it is understood that the keywords obtained from the above conversation contents are "hungry", "eat", "lightly", "Japanese food", "udon", etc. because they are mutually related in terms of content. If the keyword "soba" is extracted, it is judged to be effective (S6: YES), but "Java" that is not related to eating and drinking.
When keywords such as "flower arrangement" and "sora" are extracted, it is determined that the keyword is not valid (S6: NO).

If the keyword is not valid (S6: N
O), it is determined whether there has been a topic change (S10).
For example, when a keyword used when changing topics such as “By the way”, “After that”, and “Kondowa” is extracted (S10: YES), the keyword string stored up to that point is cleared (S11), and the process returns to S3. . However, if the topic is not changed (S10: NO), the keyword string is not cleared and the process returns to S3.

Of the keywords thus extracted,
A valid one is added to the keyword string (S7), and the data search process (S8) is executed. This data search processing is performed by the data processing unit 5d (see FIG. 1), and a search is performed using the information source stored in the internal storage medium in the search data storage unit 5f or the external storage medium in the external storage device 7. Is done. Then, it is determined whether or not the search end condition is satisfied (S9). When the information is searched, the corresponding information is narrowed down, and when the narrowed down result is, for example, about 5 to 10, it is determined that the search end condition is satisfied (S9: YES). In addition to this, it is also determined that the search end condition is satisfied when the question-tone keyword is searched from the context or the conversation is interrupted (S9: Y).
ES) and S12.

In S12, the user is asked whether or not to provide information, and if the user's answer affirms the information provision (S13: YES), information provision is executed (S14). In S12, the outline of the retrieved result and the content asking whether to output the detailed result are output. For example, the content such as “Pawn (warning sound), information. 10 candidates were found in Japanese food, udon, Matsumoto city. Would you like to give a voice guidance?” Is first output. This output is performed by voice to the user of the processing system 1 via the voice output device 6b, and is also sent as transmission data to another communication device 50 via the communication device 6a. The sound is output from a speaker or the like of 50. As a result, both parties in conversation can hear the above content. In addition, the affirmative answer in S13 may be given to one of the users who is talking. This is because the conversation voice is recognized. Then, in S14, detailed information is provided, and naturally, both parties can talk by voice as well.

In the case of this embodiment, the communication device 6a
Corresponds to "communication means", the voice input device 4 corresponds to "voice input means", and the voice output device 6b corresponds to "voice output means".
Equivalent to. The voice recognition unit 5c corresponds to the "recognition unit" and the "context determination unit", and the data processing unit 5d corresponds to the "search unit" and the "search result output control unit".

As described above, according to the processing system 1 of the present embodiment, the result of the information retrieval based on the keyword obtained by recognizing the conversational voice made by a plurality of users is
The user of the processing system 1 can be notified by outputting via the voice output device 6b, and can also be notified to the other party by transmitting to the other communication device 50 via the communication device 6a. it can. Therefore, the transmission operation of "one user tells the other party the result of the information search", which was performed in the conventional technology, is unnecessary, and the search result is shared by all the talkers without requiring any special intermediary operation of the user. it can. In other words, it is possible for both parties in a conversation to feel as if another user was speaking, and it is possible to create a situation as if a three-party call was being made.

In particular, in the case of the present embodiment, since the user adopts the "hands-free call" in which a telephone call is made without holding the telephone, it is possible to talk on the telephone while driving a car. However, if a manual operation by the user as in the prior art is required for information retrieval, the effect of making hands-free is reduced. Therefore, by automatically outputting the information retrieval result, it is possible to obtain the merit of ensuring safety during driving of the vehicle.

Further, since the processing system 1 of this embodiment is a system having a navigation function, the user may instruct the processing by the processing device using the search result. For example, in the above example, as a result of searching with keywords such as Japanese food, udon, and Matsumoto city, 10 store names are voice-guided. Therefore, a store designated by the user is used as a destination for route search and route guidance. May be. Specifically, the system will say "You can set your destination as long as you say your name."
It is preferable to provide such voice guidance.

For example, when both parties talking are driving a vehicle equipped with the processing system 1 as shown in FIG.
If either one of the talkers indicates the route search by voice as the destination, the route search / guidance is performed by the navigation function installed in both vehicles. In this way, when the meeting place is decided in the conversation, the transition to the route search / guidance to the meeting place can be easily performed, which is very convenient.

[Other Embodiments] (1) In the above embodiment, the data search processing in S8 of FIG. 2 is performed by storing in the internal storage medium in the search data storage unit 5f or the external storage medium in the external storage device 7. Although it has been described that the search is performed using the information source that is provided, the communication device 6a
Can also be used to access an external database via the Internet or the like. In this way, it is possible to search using a wider range of information resources.

(2) Regarding the provision of the detailed information in S14 of FIG. 2, not only the audio output from the audio output device 6b, but also the output output from the display device 6c may be used together. If the other communication device 50 side also has a display function, the display data may be transmitted to the other communication device 50 so that both parties can receive the information provided by voice and display. . For example, even if such a display is not performed while the vehicle is traveling, it is more convenient to use the information provided by the display when the vehicle is stopped.

(3) A supplementary note about voice recognition. For example, in the above-mentioned conversation example, there is a utterance regarding a place name such as "somewhere in Matsumoto city ...". At the city level, there are relatively few names that are the same, but at the lower-level towns and wards, for example, there are many names that are the same. For example, in the case of simply "Higashi Ward," which East Ward cannot be specified. However, simply referring to Higashi Ward is considered to mean Higashi Ward existing in the area where the user is currently. Therefore, by using the navigation function (specifically, the position specifying function), for example, if the current position is Nagoya city, the keyword “Nagoya city, Aichi prefecture” may be complemented to obtain the final recognition result. Since being in Nagoya means being in Aichi prefecture, the keyword of Aichi prefecture is also supplemented. In this way, when the user speaks the name of another municipality in the same prefecture, it is possible to respond even if the Aichi prefecture is omitted.

(4) In the above embodiment, the GPS receiver 2
a, a gyroscope 2b, and a vehicle speed sensor 2c.
Identified the current vehicle position while interpolating the error of the current vehicle position. However, such a position detector 2 is not always necessary. For example, position information may be acquired from a roadside beacon or the like, and the current position may be specified based on the position information. Further, the present location may be specified by a position specifying function such as a mobile phone or PHS.

(5) The function for realizing the above-described processing relating to voice recognition, information retrieval, provision of retrieval results, etc. in a computer system can be provided as, for example, a program activated on the computer system side. In the case of such a program, for example, it is recorded in a computer-readable recording medium such as a floppy (registered trademark) disk, a magneto-optical disk, a CD-ROM, a hard disk, and loaded into a computer system and activated as necessary. Can be used by Besides this, RO
The program is recorded by using M or a backup RAM as a computer-readable recording medium.
The OM or backup RAM may be incorporated into a computer system for use.
