It includes a unit 175, a voice recognition engine 176, an ICC control unit 177, a control unit 178 that controls each of the above units, and a plurality of applications 179.

Here, the voice recognition engine 176 constantly monitors the voice picked up by the front microphone 13 captured by the audio input unit 173, and currently uses the function of the voice recognition engine among the voices picked up by the front microphone 13. When a voice that matches the vocabulary registered in the voice recognition dictionary set by the application 179 at a predetermined level or higher is generated, the vocabulary is recognized as voice recognition and the voice recognition is successful, and the user operation associated with the vocabulary in advance is performed. It is recognized as a voice-input user operation and output to application 179 currently using the function of the voice recognition engine.

Further, the ICC control unit 177 outputs the sound picked up by the front microphone 13 captured by the audio input unit 173 to the rear speaker 16 via the audio output control unit 174, and the rear microphone 14 captured by the audio input unit 173 picks up the sound. An ICC (In-Car Communication) operation is performed to output the generated sound to the front speaker 15 via the audio output control unit 174.

Next, each application 179 displays on the front touch panel display 11 and the rear display 12 by using the function of the display control unit 172 via the control unit 178, and the touch operation input unit 171 via the control unit 178.

As shown in the figure, in this process, the occurrence of successful speech recognition in the speech recognition engine 176 is monitored (step 302).
Then, if the voice recognition success in the voice recognition engine 176 occurs (step 302), it is checked whether or not the voice input sequence is completed (step 304).
Here, the voice input sequence is output from the voice recognition engine 176, and the user operation corresponding to the vocabulary recognized in the voice recognition in which the voice recognition is successful detected in step 302 uses the function of the voice recognition engine 176. In the application 179 being used, when it is accepted by the user operation reception process that is completed by sequentially accepting a plurality of user operations by a plurality of voice inputs, the sequence of the plurality of voice inputs becomes a voice input sequence. , When it is accepted by the user operation reception process completed by accepting one user operation by a single voice input, the sequence of the single voice input becomes the voice input sequence.

Then, in step 304, the user operation reception process in the application 179 that uses the function of the voice recognition engine 176 is performed by the reception of the user operation output from the voice recognition engine 176 with the success of the voice recognition detected in step 302. When it is completed, it is determined that the voice input sequence is completed. In other words, it is determined that the voice input sequence is not completed when the user operation acceptance process in the application 179 is incomplete and the application 179 is waiting for the voice input of the user operation to be continued.

More specifically, the detection of the completion of the voice input sequence is based on, for example, the vocabulary recognized by the voice recognition in which the voice recognition is successful, which is generated in the voice recognition engine 176 detected by the control unit 178 in step 302. The application 179 using the function of the voice recognition engine 176 is inquired as to whether or not the voice input sequence is completed by accepting the corresponding user operation, the application 179 notifies the control unit 178 of the response to the inquiry, and the control unit 178 notifies the control unit 178. , It can be done by detecting the completion of the voice input sequence according to the response.

Alternatively, the detection of the completion of the voice input sequence is performed, for example, by the application 179 using the function of the voice recognition engine 176, which completes the user operation acceptance process by sequentially accepting a plurality of user operations by a plurality of voice inputs. When it starts, it notifies the control unit 178 of the start of the voice input sequence, and when the user operation reception process is completed, it notifies the completion of the voice input sequence, and the control unit 178 notifies the control unit 178 based on the notification from the application 179. It is assumed that the voice input sequence is incomplete during the period from the notification of the start of the voice input sequence to the notification of the completion of the voice input sequence, and that the voice input sequence is completed in the other period.

And the output from the front speaker 15 of the sound picked up by the rear microphone 14 are stopped.

In step 308, the ICC control unit 177 is controlled so that only the output of the sound picked up by the front microphone 13 from the rear speaker 16 is stopped, and the output of the sound picked up by the rear microphone 14 from the front speaker 15 is continued. You may. However, it is desirable that the output of the voice picked up by the rear microphone 14 from the front speaker 15 is also stopped so as not to interfere with the voice input of the user operation of the front seat user.

Next, the user in the rear seat is informed that the voice input is being performed in the front seat and the ICC operation of the ICC control unit 177 has been stopped by displaying a message on the rear display 12 for a predetermined period and the rear speaker 16. Notify by outputting a voice message from (step 310).

Then, every time the voice recognition engine 176 succeeds in voice recognition (step 312), it is checked whether or not the voice input sequence is completed (step 314).
Then, when the voice input sequence is completed (step 314), the restart of the ICC operation of the ICC control unit 177 is controlled, and the state before controlling the stop of the ICC operation of the ICC control unit 177 in step 308 is restored (step 308). Step 316).

Further, the user in the rear seat is notified that the ICC operation of the ICC control unit 177 has been restarted by displaying a message on the rear display 12 or outputting a voice message from the rear speaker 16 (step 318).
