Patent ID: 8855295

Claim:
A system comprising: at least one microphone to receive an audio signal, the audio signal to include an acoustic echo corresponding to sound output by a speaker of the system and the sound being based on a reference signal provided to the speaker; a blind source separation module to generate a plurality of source signals based at least in part on the received audio signal, compare each of the sources signals to the reference signal, determine which of the source signals has a highest correlation to the reference signal, and remove, at least in part, the source signal with the highest correlation to the reference signal from the audio signal; and at least one acoustic echo canceller to receive remaining source signals that were not removed by the blind source separation module, determine, based at least in part on the reference signal, a portion of the remaining source signals that are associated with the acoustic echo, and remove, at least in part, the determined portion from the remaining source signals to produce a processed audio signal.
