Abstract:
Voice activity detection (VAD) is an enabling technology for a variety of speech based applications. Herein disclosed is a robust VAD algorithm that is also language independent. Rather than classifying short segments of the audio as either “speech” or “silence”, the VAD as disclosed herein employees a soft-decision mechanism. The VAD outputs a speech-presence probability, which is based on a variety of characteristics.

Claim (Index 7):
The method according to  claim 6 , wherein the activity probability is the square root of the band energy speech probability multiplied by the largest of the overall energy probability, the spectral peakiness probability, and the residual energy probability.
