Voice-based control in a media system or other voice-controllable sound generating system

A method for enhanced processing of voice-based signals in a voice-controllable sound-generating system (SGS), the method comprising:

• communicating, from an SGS audio source, electronic SGS audio signals to both (a) one or more speakers for output of SGS sound waves corresponding with the electronic SGS audio signals, and (b) an audio countering system;
• receiving, at the audio countering system:
• (i) the electronic SGS audio signals communicated from the SGS audio source;
• and
• (i) audio signals representing sound waves detected by a microphone and including:
• (1) SGS-based signals corresponding with the SGS sound waves output by the one or more speakers;
• and
• (2) additional audio signals resulting from sound waves originated from one or more sources other than the SGS audio source, including voice-based signals including a voice command from a human;
• processing, by the audio countering system, the electronic SGS audio signals received from the SGS audio source to generate SGS-countered audio signals that cancel or counter the SGS-based signals included in the audio signals representing sound waves detected by the microphone, to thereby diminish sounds produced by the SGS audio source and thereby enhance the additional audio signals including the voice command;
• receiving, at a voice-control system, from the audio countering system, the SGS-countered audio signals;
• identifying, by the voice-control system, the voice command from the SGS-countered audio signals;
• and
• controlling, by the voice-control system, at least one function associated with the SGS based on the voice command identified from the SGS-countered audio signals.

A system for enhanced processing of voice-based signals in a voice-controllable sound-generating system (SGS), the system comprising:

• an SGS audio source configured to, during a period of system-based audio output, communicate electronic SGS audio signals to both (a) one or more speakers for outputting SGS sound waves corresponding with the electronic SGS audio source and (b) an audio countering system;
• the audio countering system configured to:
• receive the electronic SGS audio signals from the SGS audio source;
• and
• receive audio signals from a microphone, the received audio signals including:
• (i) SGS-based signals corresponding with the SGS sound waves output by the one or more speakers;
• and
• (ii) additional audio signals resulting from sound waves originated from one or more sources other than the SGS audio source, including voice-based signals including a voice command from a human;
• use the electronic SGS audio signals received from the SGS audio source to generate SGS-countered audio signals that cancel or counter the SGS-based signals included in the audio signals received from the microphone, to thereby diminish sounds produced by the SGS audio source and thereby enhance the voice command;
• and
• a voice-control system configured to:
• receive from the audio countering system the SGS-countered audio signals that diminish sounds produced by the SGS audio source;
• identify the voice command from the SGS-countered audio signals;
• and
• control at least one function associated with the SGS based on the voice command identified from the SGS-countered audio signals.
