FIG. 2 is a flow chart for describing the outline of an example of an operation of the voice assistant system 1 of FIG. 1. The outline of an example of the operation of the voice assistant system 1 of FIG. 1 is described with reference to FIG. 2.

In FIG. 2, each request module 23 records a user's speech through the microphone 22 when a user speaks in the plurality of devices 20 (Step S1). When the user's predetermined verbal start command (for example, Hello, oo) is input, for example, the request module 23 may start an operation to record the contents of the subsequent user's speech.

Each request module 23 acquires the recording state information indicating the recording state in recording the user's speech (Step S2). Furthermore, each request module 23 acquires the usage state information indicating the current usage state of the device (Step S3).

Each request module 23 transmits the recorded user's speech (recorded data), the recording state information, and the usage state information to the server apparatus 10 through the communication module 21 (Step S4).

In the server apparatus 10, the voice recognition module 12 receives the recorded user's speech (recorded data), the recording state information, and the usage state information sent out from the plurality of devices 20 through the communication module 11 (Step T1).
