ABSTRACT:
What is disclosed is a signal processing system, wherein a method and apparatus identify background noise in a signal containing speech and noise by separating the signal into frames, evaluating energy levels of selected frames, and identifying the frames as noise if certain consistency tests are met, and speech if certain pulsing, monotone, and speech level tests are met, and transition between speech and noise if transition deviation and consistency levels are met.
