Voice controlled audio recording or transmission apparatus with keyword filtering

摘要

A method includes obtaining a plurality of audio channels using a plurality of microphone outputs having at least one audio control channel and at least one audio output channel. When a keyword is detected on the audio control channel using voice recognition, adaptive filtering is performed to attenuate the keyword from the audio output channel. An apparatus operative to perform the method includes a plurality of microphones that provide a plurality of audio channels with at least one audio output channel and at least one audio control channel. Voice command recognition logic is operatively coupled to the plurality of microphones to receive the at least one audio control channel. The voice command recognition logic detect keywords on the audio control channel and filter logic with at least one adaptive filter performs adaptive filtering to attenuate the keyword from the at least one audio output channel.
