A Novel Digital Speech Detector for Improving Effective Satellite Capacity
E. Fariello · IRE Transactions on Communications Systems · 1972
A probabilistic analysis has been done by comparing cumulative distributions of voice and typical telephone-line noise, and the characteristics of voice waveform have been investigated in order to determine a new criterion for distinguishing the two signals. This digital speech detector is extremely sensitive to the onset of voice signal but much less sensitive to typical telephoneline noise.
