Abstract
A method for using a voice operated switch in a changing high noise environment involves determining a relative energy of the background noise, calculating VOX, voice, and delta thresholds, and comparing the VOX threshold to an amplitude of an incoming data sample. When the amplitude of the incoming data sample is greater than the VOX threshold, then the delta threshold is compared to the short-term average delta. When the amplitude of the short-term average delta is greater than delta threshold, then the voice threshold is compared to the short-term average. When the short term average is greater than the voice threshold, then the incoming data sample is determined to be voice and the voice operated switch is actuated.
