Abstract:
Provided is a system for a robot to eliminate its own sound source, comprising a sound pickup unit (1) used for acquiring a digital signal having mixed left and right sound channels and outputting same; a sound-card driver unit (2) used for mixing the received reference signal of the robot sound source and the digital signal having mixed left and right sound channels, to form a mixed voice signal, and outputting same; a signal separation unit (3) used for separating the mixed voice signal into a digital signal having mixed left and right sound channels and a reference signal, and determining whether the digital signal having the mixed left and right sound channels contains an interference signal, obtaining a playback signal volume, and outputting same.
