ABSTRACT:
A multiple wireless microphone speakerphone system includes one or more wireless microphones. The wireless microphones accept speech and transmit the speech to receivers, one receiver corresponding to each wireless microphone. Audio processing and acoustic echo cancellation (AEC) are performed on the received speech signals. A signal handling unit generates an audio signal after echo cancellation. The generated audio signal is transmitted to a far end to be played through, for example, a speaker or an ear piece.
