Abstract
An audio/video system may generate audio data for a user. The user in turn may provide voice commands to the audio/video system. The audio generated by the system may be adaptively delayed, amplitude adjusted, and subjected to sampling interval shifting before subtracting it from the composite signal received from a microphone. As a result, the audio generated by the system can be subtracted from a signal representing both the audio generated and the spoken command to facilitate the recognition of the spoken command. In this way, a voice responsive audio/video system may be implemented.
