Abstract
The present invention provides monitoring a sounding state of a speaker even in a case where any given sound is broadcast. In detecting the sounding state of the speaker with the microphone for sound detection, noises around the speaker are also collected by the microphone for sound detection. Therefore, in a case where there are ambient noises, it is difficult to monitor the sounding state of the speaker.
