Abstract
An audio processing apparatus includes a processor coupled to a memory. The processor receives an audio signal from a microphone serving to collect sound in a space. The processor determines whether a level of a reference signal is equal to or greater than a threshold. The reference signal is a reproduction signal reproduced by a speaker serving to output audio sound to the space. The processor outputs, as an output signal to a speech recognition device, a removal signal obtained by removing an audio component of the reference signal from the audio signal. The processor outputs, as an output signal to the speech recognition device, a replacement signal in place of the removal signal in response to determining that the level of the reference signal is equal to or greater than the threshold. The replacement signal is at least one of comfort noise and a mute signal.
