〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 1 is a keyboard, 3 is a handle remote control operation unit, 4 is a display unit, 5 is a preset memory, 6 is a voice synthesis circuit, 7 is a speaker, 8 is a microphone, 9 is a radio unit, 10 is an antenna, and Since these parts are the same as or equivalent to those in the conventional system, which are denoted by the same reference numerals in FIG. 3, detailed explanations will be omitted.

Further, reference numeral 12 denotes information 1 of the other party using the voice input from the microphone 8, for example, the voice Ls of the name of the other party.
13 is a voice recognition circuit 12 that performs recognition.
A voice registration unit 14 is a voice registration unit 13 in which the correspondence between the name of the other party who is voice recognized and the speed dial number given to the complete dial number of the other party is registered.
Built-in.

This system is different from the conventional system in that the calling process is performed by obtaining the corresponding complete dial number from the preset memory 5 in accordance with the speed dial number output from the voice registration section 13 based on the name of the other party inputted by voice through the microphone 8. They are different converters. 15 is connected to the converting part 14 and placed on the head of a handbrake lever of a car, etc., and the converting part 1
4 is a mode switching unit that instructs to start/end a voice transmission mode based on voice information. 16 is preset memory 5
, speech synthesis circuit 6. Speech recognition circuit 12. This is a car phone adapter consisting of a conversion section 14 having a built-in voice registration section 13.

Next, the operation will be explained. When registering the correspondence between the name of the other party and its speed dial number in the voice registration section 13, first, register the name in the area corresponding to each speed dial number in the preset memory 5 in the same way as in the conventional case. , then 0 where the corresponding complete dialed number is stored,
When the user operates the registration key of the mode switching unit 15, the conversion unit 13 shifts to the voice registration mode, and inputs the name of the person on the other end of the call with the speed dial number ``'0'''' to the voice synthesis circuit 6 by voice. please do it. ” etc. Send a message code. The speech synthesis circuit 6 synthesizes speech of the above-mentioned message using this code, and outputs the speech from the speaker 7. In accordance with this message, the user enters the name of the communication party whose complete dial number has been given the speed dial number "On" into the microphone 8 when registering the preset memory 5.
Enter voice input.

The name of the communication partner input by voice through the microphone 8 is sent to the voice recognition circuit 12 and is voice recognized.

The result is sent to the conversion section 14. The conversion unit 14 registers in the voice registration unit 13 the correspondence between the voice recognition information of the name of the recipient and the speed dial number KgO##. If the registration is successful, the conversion unit 14 sends a predetermined code to the speech synthesis circuit 6, and a confirmation sound, for example, "bean", is sent out from the speaker 7. In addition, if registration is not successful, a predetermined code is sent to the speech synthesis circuit 6,
For example, a warning sound such as "beep beep" or a message requesting retransmission is sent out from the speaker 7. Thereafter, similar processing is performed to sequentially register, and when the user operates the end key of the mode switching section 15 after the registration is completed, the conversion section 14 ends the registration processing to the voice registration section 13.

Next, when making a speed dial call using voice input, first operate the start key of the mode switching unit 15 to instruct call processing based on voice information, then the conversion unit 14 shifts to the voice call mode and performs one, e.g. A code for a message such as "Please input the name of the other party by voice" is sent to the speech synthesis circuit 6.

The speech synthesis circuit 6 uses this code to output the above-mentioned message to the audio stand, and outputs the message from the speaker 7.

When the user vocally inputs the name of the communication partner through the microphone 8 according to this message, the name of the communication partner is sent to the speech recognition circuit 12 for speech recognition, and the result is sent to the conversion section 14.

When the conversion unit 14 receives the voice recognition information of the name of the communication partner, it converts it into the speech synthesis circuit 6, which converts the message code for repeating the name of the communication partner and the message code such as "Do you want to connect the phone?" and output the audio from the speaker 7. When the user responds with "yes," the voice recognition circuit 12 recognizes the voice and sends it to the conversion unit 14, and upon receiving it, the conversion unit 14 converts the voice registration unit 13 into an abbreviation corresponding to the name of the communication partner. 0 Next, the preset memory 5 is accessed based on the abbreviated dial number, and the complete dial number of the communication partner is read from the corresponding area and sent to the radio unit 9. Radio section 9
modulates the complete dialed number and transmits it from the antenna 10 to the car telephone base station. At this time, the display on the display unit 4 also changes to a corresponding display based on the result of the voice recognition.

Processing of incoming and outgoing calls, or switching from handset to hands-free calls, etc., can be done by key operations on the steering wheel remote controller 3, and processes of handset and handset calls can be handled by operations on the telephone side, as in the conventional case. is executed in the same way.

Next, FIG. 2 is a block diagram showing another embodiment of the present invention, in which the voice registration section 13 is arranged in the voice recognition circuit 12, and the mode switching section shares the keys of the steering wheel remote control operation section 3. This embodiment differs from the embodiment shown in FIG. 1 in that it is realized by.

In this embodiment, when registering in the voice registration section 13, after the registration in the preset memory 5 is completed, the start key of the steering wheel remote control operation section 3 is operated to set the hands-free mode, and then the end key is operated. In the conventional converter 2, the operation of the end key before starting a call is invalidated, but in the converter 14 of this embodiment, the operation shifts to the voice registration mode. Thereafter, similar to the embodiment shown in Fig. 1, a message such as "Please enter the name of the person on the other end of the call with the speed dial number 'O' by voice" is sent, and when the name of the person on the other end of the communication is returned, the voice recognition circuit 12 performs voice recognition of the name of the other party, and registers the correspondence between the information and the speed dial number in the built-in voice registration section 13.

The voice registration mode is terminated by re-operating the end key of the steering wheel remote control operation section 3.

Next, when executing the transmission process in the voice transmission mode, the start key of the steering wheel remote control operation section 3 is operated. As a result, as in the conventional case, a state of waiting for a hands-free operation before transitioning to a hands-free call is established. Taking advantage of this state, the conversion unit 14 converts the code of a message such as "Please input the name of the other party by voice" to the voice synthesis circuit 14.
When the name of the other party is returned, the voice recognition circuit 12 recognizes the voice, obtains the corresponding speed dial number from the built-in voice registration section 13, and sends it to the conversion section 14.
Send to. Thereafter, in the same manner as in the embodiment shown in FIG. 1, the conversion unit 14 obtains the complete dial number of the communication partner and executes the outgoing call process.
