The audio distribution unit 64 is instructed to continue inputting. As a result, in the information processing system 40, the drive recorder 38, which needs to constantly record audio, can constantly record audio even during a hands-free call.

For example, based on the priority table 68 stored in the second memory 61 in advance, the control unit 67 determines which of the other audio processing units 65 whose audio input should be stopped when the operation of one of the audio processing units 65 is started. can be specified. FIG. 3 is a diagram showing an example of the priority table 68. In FIG. 3, the first line excluding the title line at the top line indicates the priority of the recording section 65a of the drive recorder 38, and the second line indicates the priority of the call processing section 65c. Furthermore, the third to fifth lines indicate the priorities of the three first agent function units 65b1, second agent function units 65b2, and third agent function units 65b3, respectively.

In the example shown in FIG. 3, the recording section 65a of the drive recorder 38 is given the highest priority "1", and the call processing section 65c is given the next highest priority "2". Further, the same priority level "3" is given to each of the three agent function units 65b.

When the detection unit 66 detects the start of operation in any of the audio processing units 65, the control unit 67 refers to the priority table 68 and determines the priority given to the audio processing unit 65 that has started the operation. Then, the audio distribution unit 64 is instructed to stop audio input to the audio processing unit 65 that has been specified and given a priority equal to or lower than that priority. As a result, in addition to the above-mentioned operations, the control unit 67 also controls the operation of the second agent function unit 65b2 and the third agent function unit when the detection unit 66 detects the start of the operation of the first agent function unit 65b1. This will instruct the audio distribution unit 64 to stop audio input to the audio distribution unit 65b3.

Furthermore, when the call processing unit 65c is executing call processing, the control unit 67 displays information on the audio processing unit 65, into which audio is input from the audio distribution unit, on the touch panel 15, which is a display device. FIG. 4 is a diagram showing an example of a voice input information screen displayed on the display 16 of the touch panel 15 by the control unit 67.

In the voice input information screen 72 shown in FIG. 4, corresponding to the recording section 65a, call processing section 65c, first agent function section 65b1, second agent function section 65b2, and third agent function section 65b3 of the drive recorder 38, Labels 73a, 73b, 73c, 73d, and 73e written as "drive recorder," "hands-free call," "first agent," "second agent," and "third agent" are displayed.

When the switching instruction is input in step S108 (S108, YES), the control unit 67 switches on/off the audio input of the corresponding audio processing unit 65 according to the input switching instruction (S110).

Subsequently, the detection unit 66 determines whether the call has ended (S112). When the call ends (S112, YES), the control unit 67 turns on audio input to all audio processing units 65 (S114), and ends the process.

On the other hand, if the switching instruction is not input in step S108 (S108, NO), the process moves to step S112. On the other hand, if the call has not ended in step S112 (S112, NO), the detection unit 66 returns the process to step S108.

On the other hand, when the start of a hands-free call is not detected in step S102 (S102, NO), the detection unit 66 determines whether or not the start of operation of any agent function unit 65b is detected (S116). Then, when the operation of the agent function section 65b has not started (S116, NO), the detection section 66 returns to step 102 and repeats the process.

On the other hand, when any of the agent function units 65b starts operating (S116, YES), the control unit 67 refers to the priority table 68 and stops inputting audio to the other agent function units 65b (S116, YES). S118).

Next, the control unit 67 displays audio input information, which is information from the audio processing unit 65 into which audio is input from the audio distribution unit 64, on the touch panel 15 (S120). Next, the control unit 67 determines whether a switching instruction regarding voice input has been input from the vehicle user (S122). When the switching instruction is input (S122, YES), the control unit 67 switches on/off the audio input of the corresponding audio processing unit 65 according to the input switching instruction (S124).

Subsequently, the detection unit 66 determines whether the operation in the agent function unit 65b started in step S116 has been completed (S126). When the above operation is completed (S126, YES), the control unit 67 moves the process to step S114.

On the other hand, if the switching instruction is not input in step S122 (S122, NO), the process moves to step S126. On the other hand, in step S126, if the operation in the agent function unit 65b started in step S116 has not been completed (S126, NO), the detection unit 66 returns the process to step S122.
