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 5):
The method according to  claim 4 , wherein the plurality of different speech probabilities comprises:\n an overall energy speech probability based on an overall the energy of the audio data; a band energy speech probability based on an energy of the audio data contained within one or more spectral bands; a spectral peakiness speech probability based on an energy of the audio data that is concentrated in one or more spectral peaks; and a residual energy speech probability based on a residual energy resulting from a linear prediction of the audio data.
