Alango's Voice Activity Detection (VAD) technology demo
Alango Voice Activity Detection (VAD) is an embedded DSP-based technology aimed to discriminate between the human speech and non-speech signal. The stand-alone VAD consumes very little power and allows “heavier” signal processing tasks (such as speech recognition) to cease activity and the DSP to sustain a low-power consumption mode as long as human voice activity is not detected. Alango VAD technology implements a proprietary high resolution spectrum noise estimation algorithm allowing reliable voice detection and keeping false detection rate low.
