You can set the output level.

While outputting the audio data, the controller 11 may recognize the user's voice in operation S31. In this case, the controller 11 determines whether the voice recognized in step S33 is a command corresponding to the preset voice. That is, the controller 11 may check whether the recognized voice corresponds to a manufacturing process of the terminal 10 or a command set by the user. For example, the voice may be a voice corresponding to a command such as stop, next, previous, play, end, and quiet.

If the recognized voice corresponds to a preset command, the controller 11 changes and executes audio data output from the sound source output device 20 according to the recognized voice in step S35. Meanwhile, when the recognized voice does not correspond to the preset command, the controller 11 may process the recognized voice as noise.
