The voice assistant/client program (application) 212c records a user's speech after a user's predetermined verbal start command is input through the audio device 217, and then transmits recorded data of the user's speech to the server apparatus 10. Moreover, the voice assistant/client program (application) 212c acquires the recording state information from the audio device 217, and then transmits the same to the server apparatus 10 or acquires the operation state information from the OS 212a, and then transmits the same to the server apparatus 10, for example. Furthermore, when there is an instruction of outputting the voice assistant from the server apparatus 10, the voice assistant/client program a (application) 212c causes the speaker 206 or the headset 300 to output the same in voice through the DSP 218 or causes the monitor 203 to display the same.

In the above-described configuration, the control module 210, the audio device 217, the voice assistant/client program (application) 212c, and the like can realize the functions of the request module 23 of FIG. 1. Moreover, the audio device 217 or the monitor 203 can realize the functions of the output unit 24 of FIG. 1.
