Abstract: A multi-microphone device that can perform acoustic echo cancellation (AEC) without an external reference signal. The device uses the audio data from one of its microphones as a reference for purposes of AEC and acoustic noise cancellation (ANC). The device determines filter coefficients for an adaptive filter for ANC when cancelling one microphone signal from another microphone's signal. Those filter coefficients are buffered and delayed and then used for AEC operations cancelling one microphone signal from another microphone's signal. When desired audio (such as a wakeword, speech, or the like) is detected, the device may freeze the coefficients for purposes of performing AEC until the desired audio is complete. The device may then continue adapting and using the coefficients.
