A system for enhanced processing of voice-based signals in a voice-controllable sound-generating system (SGS) is provided. An SGS audio source may communicate electronic SGS audio signals to both (a) one or more speakers, which output corresponding SGS sound waves and (b) an audio countering system. A microphone may detect sound waves and output corresponding audio signals including: (a) distorted SGS audio signals corresponding with SGS sound waves and (b) additional audio signals originated from other sources, e.g., including voice-based commands. The audio countering system may (a) receive the electronic SGS audio signals from the SGS audio source; receive signals from the microphone representing the microphone-detected sound waves, and (c) use the electronic SGS audio signals received to cancel or counter the distorted SGS audio signals included in the microphone-received audio signals, to thereby enhance any voice-based commands included in the received audio signals.
