Abstract
The detection of voice (speech) signal presence in input signal-plus-noise is improved by more accurate determination of the decision threshold, which is determined by first finding a medium-length interval consisting of noise-signal-noise (no-signal, signal, no-signal), then calculating a histogram (energy probability distribution) for the interval, then finding the maximum value of variance of the histogram as the optimal threshold, plus an arbitrary offset.
