DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a portable information terminal having a voice communication function and a voice recognition function, a control method thereof,
And a storage medium storing a control program for the portable information terminal.

[0002]

2. Description of the Related Art In recent years, with the advent of a highly information-oriented society, various information processing apparatuses have been developed, and communication networks for information of those apparatuses have been improved, and communication apparatuses such as computers, telephones, and modems have been developed. Various new devices have come to be used.

In particular, portable information communication devices include:
Mobile phones (including PHS) are rapidly spreading. A mobile phone is capable of communicating with a remote party via voice via wireless communication. With the spread of the mobile phone, a public wireless telephone network is being developed and expanded as a social infrastructure.

As information processing apparatuses, handy terminals, notebook-type and sub-note-type personal computers, etc. are also rapidly spreading. These information processing devices have also been significantly reduced in size, and portable terminals that do not cause any pain even when being carried at all times have been commercialized.

[0005] Products integrating these portable telephones and portable terminals have recently been commercialized. In addition to products that simply house communication and information processing functions in one housing, for example, telephones, modems,
There are various forms such as supply in the form of a C card.

[0006]

By the way, it is premised that portable terminals that are currently commercialized are operated / data-inputted by pen input or key input. Therefore, in order to operate / input data on the terminal, it is essential that both hands can be used freely, such as supporting the terminal with one hand and inputting with the other hand.

[0007] This means that the terminal cannot operate / input data unless both hands are free. In other words, there is a problem in that the portable terminal can be carried anywhere and the operation / data input can be performed at any time.

In view of this problem, it is conceivable to use a voice input method. That is, when the operator inputs voice by speaking to the terminal, the voice input at the terminal is recognized and interpreted so that it can be handled as an operation command or data of the terminal, so that the operator can freely use only one hand. Even when this is not the case, operation / input of the terminal becomes possible.

However, even when this voice input is employed, there are the following problems.

1) Although the operation / data input of the portable terminal is possible by the voice input of the operator, if the device also has a communication function, for example, a case where the device has a call function, the conventional technology requires that It is not possible to recognize the voice of the person, and even if the address and telephone number of the person who wanted to know the address and telephone number from the other party are heard, the user remembers it in his head, or Write on paper, and then start up the address book software and enter data by pen or key input, or enter the above-mentioned operator's voice by voice recognition.
It required heavy labor and the input operation was very troublesome.

2) As means for solving the above problem 1), means for recognizing the voice of the other party during a call and storing the voice recognition data as data of the portable terminal is conceivable. In this case, it is desirable that the voice can be recognized while the voice is output to the speaker. However, there is a limit in performing such processing in real time with the hardware of the form terminal, and the voice must be stored once and then output to the speaker. Must. For this reason, in a portable information terminal in which miniaturization is most important, there is a problem that the configuration is increased and the terminal is correspondingly enlarged.

3) A portable terminal does not have a keyboard,
A configuration using a touch panel integrated with a display is also often used. In many cases, a speaker for audio output is integrated with the main body to simplify the configuration. In such a configuration, especially when using a touch panel,
Visual recognition of the touch panel is indispensable, and voice recognition starts /
At the end timing, it is necessary to remove the speaker from one ear, hold the terminal with one hand, and input with the other hand, and switch the device busy to operate. In addition, there is a problem that it is necessary to remove the device from the ear once, and one-handed operation is not easy.

4) Conventionally, after the speech recognition is started, all the speech recognition result data is stored in the storage means, so that a large storage capacity is required or processing is possible when the storage capacity is limited. There is a problem that the data capacity is reduced.

5) The user interface for giving commands to the apparatus by voice input is convenient, but it is impossible to use it together with the process of recognizing the voice of the other party. That is, at the end of voice recognition, the portable terminal indicates by voice to the mobile terminal that the other party on the call has finished speaking the voice data to be recognized, and the mobile terminal recognizes the call and displays the voice recognition result data on the display unit. There is a possibility that the operation of displaying the message and terminating the voice recognition after the operator sees the display may complicate the operation of the user.

6) It is conceivable that the connection with the telephone line network is made by wire. However, there is a problem that the simplicity, which is a feature of the portable terminal, that a call can be made anytime and anywhere, is impaired.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide a portable information terminal which can be configured simply and inexpensively, which can recognize voice information obtained from a communication partner by a simple operation and store it in a reusable form. To provide.

[0017]

According to the present invention, in order to solve the above problem 1, in accordance with an input from a predetermined operation means, a start or end timing of recognition of a voice signal by the voice recognition means is determined. , And the voice recognition data is stored.

In order to solve the above problem 2, in the present invention, the output destination of the voice data input from the line connection means at the start of the recognition of the voice of the other party during the call is changed from the voice output means to the voice recognition means. A configuration is adopted in which switching is performed so that voice during a call is not output to the voice output unit.

In order to solve the above problem 3, according to the present invention, when the voice of the other party during a call is voice-recognized and the recognition result data is stored as data of the portable terminal, the recognition start timing of the voice signal is determined. In this case, a key switch is used as the operation means.

In order to solve the above problem 4, in the present invention, after the recognition of the voice signal is started, predetermined voice information is detected in the received voice signal, so that the voice recognition means recognizes the voice signal. A configuration is adopted in which the start timing of the process of storing the result in the storage means is determined.

In order to solve the above problem 5, in the present invention, after the recognition of the voice signal is started, predetermined voice information is detected in the received voice signal, so that the voice recognition means recognizes the voice signal. A configuration is adopted in which the end timing of the processing for storing the result in the storage means is determined.

In order to solve the above problem 6, the present invention employs a configuration in which connection to a telephone line network is made by a wireless communication system.

(Detailed Operation Description) Hereinafter, two embodiments of the operation in the above hardware configuration will be described.

[Embodiment 1] First, the aforementioned problems 1) to 1)
An embodiment for solving 4) and 6) will be described.
The present embodiment relates to the operation of the mobile information terminal when the voice of the call is recognized by the mobile information terminal 101 and the voice recognition data is stored as the data of the mobile terminal. FIG. 1 shows a control procedure performed by the computer. The illustrated procedure stores the system main control unit 1 in the storage unit 109.
02 is stored as a program. FIG. 2 shows only a procedure for performing voice communication.

First, the operation until the portable information terminal is in a call will be described (steps S201 to S208).

When the power supply of the portable terminal is turned on (step S201), it is determined whether or not to make a next call (call) (step S202). The telephone button is pressed to activate the telephone software stored in the storage unit 109 (step S203).

The operator inputs the telephone number into the command input unit 110
(Step S204), the PHS wireless control unit 104 and the PHS wireless unit 105
(Step S205). When the other party goes off-hook, a call is in progress (step S206).

If no call is made (the selected operation is not a telephone function), the flow shifts to step S207 to determine whether or not a call has been received (incoming) by the PHS wireless communication system. If no telephone call is received, the process loops to step S202 and waits for an incoming or outgoing call as described above.

When a call is received, the user goes off-hook from command input section 110 and receives the call (step S208). The detection of this off-hook is based on the command input 1
When the predetermined switch 10 is operated, or when the speaker 106 and the microphone 107 are configured as a handset, the operation is performed by literally detecting the off-hook of the handset.

A call is started by any of the above operations (step S206). During a call, the voice passage control unit 103 outputs the input voice from the microphone 107 to the PHS wireless control unit 104 and outputs the data received by the PHS wireless unit 105 and the input voice from the microphone 107 to the speaker 106. A call is made.

As described above, by connecting to the telephone line network by the PHS wireless communication system, since the connection to the public line network is made by wireless communication, it is possible to connect the line and talk anytime and anywhere.

Thus, the portable information terminal is busy. Next, an operation (step S209 and subsequent steps) of recognizing a speech voice and storing the speech recognition result data will be described. The call voice includes the voice of the operator, and the configuration of the present embodiment can be used as it is for the voice recognition of the operator. The following describes an example of inputting as "?".

The operator of the apparatus uses the portable information terminal to input the address and telephone number (not limited to the address and telephone number of the other party, but may be the address and telephone number of another person known to the other party) during a call with the other party. If the user wants to input the data to the terminal 101 (step S209), the user presses the voice recognition key switch 111 to recognize the voice of the other party (step S210).

When the key switch 111 for voice recognition is pressed, the voice passage control unit 103 causes the PHS radio control unit 104 to operate.
The output path of the audio data sent from
06 to the voice recognition unit 108 (step S2).
11).

As a result, the sound data is not transmitted to the speaker 106, and no sound is output from the speaker. Therefore, since the voice data can be directly input to the voice recognition unit 108 for voice recognition without storing the voice data once, no extra storage means for storing the voice data is required. It can be configured simply, inexpensively, and small and light.

Thus, the voice recognition of the voice recognition unit 108 is started (step S212).

The voice recognition unit 108 detects data for starting the storage of the voice recognition result, notifies the timing to the system main control unit 102, and from that point on, the system main control unit 102 recognizes the data in the storage unit 109. Then, storage of data such as an address and a telephone number converted into a character code or the like is started (or the speech recognition unit 108 outputs a recognition result from a data detection timing for simply causing the speech recognition result data storage unit to start storing). The configuration may be such that the

The data for starting the storage of the voice recognition result is a predetermined word in the voice of the other party (the voice of a word corresponding to the starting point of the address data such as "Tokyo" or "zip code" or "03". ), Etc.), but the configuration is such that the start of voice recognition is simply detected when the amplitude level of the voice exceeds a predetermined threshold. Is also good.

The system main control unit 102 includes the voice recognition unit 1
Then, the storage start notification notified from step 08 is recognized, and then the voice recognition result data output from the voice recognition unit 108 is stored in the storage unit 109 (step S214). As described above, the process of starting the recognition in accordance with the predetermined data in the voice signal of the other party or the state of the voice signal can reduce the storage capacity of the storage unit 109.

The end timing of the voice recognition is determined by pressing the key switch 111. However, in the present embodiment, as described above, since monitoring by the speaker 106 is not performed, it is necessary to detect the end of the voice signal of the other party to be recognized by some method.

In this embodiment, the operator operates the display unit 112
The end of the recognition is determined by looking at the display of the recognition result performed in step (1).

That is, the speech recognition result data by the speech recognition unit 108 is sent to the display unit 112 under the control of the system main control unit 102 and displayed (step S21).
5).

The operator recognizes that the caller has finished speaking the address and telephone number by viewing the display of the recognition result displayed on the display unit 112 (step S216), and presses the key switch 111 for terminating the voice recognition. (Step S217).
As is apparent from the loop from steps S216 to S213, the recognition result data sent from the voice recognition unit 108 is sequentially displayed. The operator can determine the data recognition end timing by looking at the display.

When the key switch 111 is pressed, the system main control unit 102 sets the audio data transmission path to the original path, that is, the PHS radio control unit 104 → the audio path control unit 10.
3 → speaker 106), whereby the voice of the other party is output from the speaker (step S21).
8).

As described above, by starting / ending the voice recognition by the key switch 111, it becomes possible to start / end the voice recognition of the portable information terminal by one-handed operation. As described above, the key switch 111 is used as a part of the trigger of the voice recognition. However, since the section in which the voice signal is to be recognized is actually based on the voice recognition, the key switch 111 is transmitted from the speaker 106 as in the related art. There is no need for the operator to determine the recognition timing by himself while listening to the voice.

Further, by stopping the monitor output from the speaker 106, the operator can concentrate on the operation of the key switch 111 and the output of the display unit 112, so that an unnecessary psychological burden is not given to the operator.

Further, by using a key switch irrespective of voice input or touch panel input, voice recognition operation becomes extremely easy and easy to understand. For example, it is not necessary to visually recognize the operation surface of the touch panel, and it is possible to perform an operation with a hand gesture, and as described in the above problem 3), there is no need to operate the device while holding the device busy.

In step S219, it is detected whether or not to end the call. This detection is performed by detecting a predetermined key of the command input 110 or a literal on-hook, similarly to the off-hook. When the operation to end the call is performed, P
The PHS radio control unit 104 is controlled via the HS radio unit 105 to disconnect the call connection (step S220).

According to the above-described embodiment, during a call, the voice of the call is recognized and stored as data of the portable information terminal. It is not necessary to store the data, and data can be easily input / stored.

[Second Embodiment] In the above, the operator determines the end timing of the voice recognition by looking at the display on the display unit 112. However, the end timing of the speech recognition can also be performed by detecting a word in a particular speech or a particular speech signal, similarly to the start of speech recognition.

The following embodiment shows an example in which the end timing of speech recognition is determined by detecting a word in a specific voice or a specific voice signal, and solves the above-mentioned problem 5. Things.

FIG. 3 is a flowchart similar to that of FIG. 2 except that steps having numbers in the 300s are used for the step numbers, and steps having the same step numbers in the 10s in FIG. The processing is substantially the same as the corresponding step 2. Hereinafter, only processing different from FIG. 2 in FIG. 3 will be described.

FIG. 3 differs from FIG. 2 in step S316.
And that there is no operation of the key switch 111 corresponding to step S217.

In this embodiment, the determination of the end timing of the speech recognition (step S316) is based on the word in the specific speech,
Alternatively, detection is performed by detecting a specific voice signal. For this purpose, a word in a specific voice or a specific voice signal is detected by the voice recognition unit 108 in the same manner as at the start of voice recognition. For example, when words such as “finished” and “end” in the voice of the other party are recognized by the voice recognition unit 108, the voice recognition may be terminated. Alternatively, a method of requesting the other party to perform an appropriate ten-key operation and detecting the frequency may be used. Alternatively, the end timing of the speech recognition may be detected by detecting a state of silence (or the amplitude level of the speech is equal to or less than a predetermined value) for a predetermined time or more.

That is, in the present embodiment, step S316
The end timing of the voice recognition is determined not by the user operation but by the recognition processing itself, that is, by predetermined data in the voice signal of the other party, or in response to a change in the state of the voice signal.

When the end timing of the speech recognition is detected, the system main control unit 102 terminates the speech recognition of the speech recognition unit 108 and changes the speech data transmission path to the original path (PH).
The processing returns to the S wireless control unit 104 → the voice passage control unit 103 → the speaker 106). Subsequent processing is the same as in FIG.

As described above, by ending the voice recognition by the voice of the other party, it is not necessary for the operator to determine whether to end the voice recognition by seeing the end display, and to perform the voice recognition without performing the explicit recognition ending operation. Recognition can be completed more easily. Further, the storage capacity of the storage unit 9 can be saved.

The hardware and software configurations shown in the above description are merely examples, and it is needless to say that those skilled in the art can make various modifications without departing from the scope of the present invention. For example, each part of the configuration shown in FIG. 1 does not need to be housed in an integrated housing, and any part may be supplied as optional parts or may be externally attached. The communication system may be a system using a PHS line, a normal wired public line, a dedicated line, a mobile phone line, a car line, or a satellite line. In particular, in the above-described embodiment, the PHS of the wireless connection is premised, but it goes without saying that the same effect can be expected even with a wired line in recognizing the voice of the other party.

The apparatus may have a facsimile function and a data communication function in addition to the call function. Further, the apparatus may have any form such as a multifunctional mobile phone or a mobile personal computer. In short, it goes without saying that the present invention can be implemented as long as the communication device aims to use the communication function and information obtained from the other party as data.

[0072]

As is apparent from the above, according to the present invention, the start or end timing of speech signal recognition by the speech recognition means is determined in accordance with the input of the predetermined operation means.
By adopting a configuration that recognizes the voice data of the other party and stores the voice recognition data, the voice of the other party is recognized by voice and stored as data of the portable information terminal, so that the operator can recognize the voice from the other party. There is an excellent effect that data input / storage can be easily performed without having to input / store the data in the portable information terminal by himself / herself from the voice heard.

Further, at the start of the recognition of the voice of the other party during the call, the output destination of the voice data input from the line connection means is switched from the voice output means to the voice recognition means, and the voice during the call is output to the voice output means. Since a configuration that prevents such a situation is adopted, no extra storage means for storing voice data is required, and the portable information terminal can be configured simply, inexpensively, and in a small size and light weight.

Further, the voice of the other party during the call is recognized by voice,
When the recognition result data is stored as data of the mobile terminal, by adopting a configuration using a key switch as an operation means for determining a timing of starting a recognition of a voice signal, a method of inputting voice signal or touch panel input is used. The voice recognition operation becomes extremely easy and easy to understand, and the voice recognition can be started / terminated by one-handed operation.

After the recognition of the voice signal is started, predetermined voice information is detected in the received voice signal,
By adopting a configuration in which the start timing of the process of storing the recognition result of the voice signal by the voice recognition unit in the storage unit is determined, the storage capacity of the storage unit for storing the recognition result can be reduced, and the portable information terminal can be used. It can be configured simply, inexpensively, and small and light.

Further, after the recognition of the voice signal is started, predetermined voice information is detected in the received voice signal, so that the processing of storing the recognition result of the voice signal by the voice recognition means in the storage means is completed. By adopting the determined configuration, it is possible to reduce the storage capacity of the storage unit that stores the recognition result, and it is not necessary to perform an explicit recognition end operation, so that the operation of the apparatus becomes easier.

Further, by adopting a configuration in which the connection with the telephone line network is made by the wireless communication system, it is possible to perform a voice communication with the portable information terminal and a voice recognition process of voice information obtained by the voice communication anytime and anywhere.

As described above, according to the present invention, the portable information terminal has an excellent effect of recognizing voice information obtained from a communication partner by a simple operation and storing it in a reusable form. There is.
