Abstract

Voice activity detection system includes a plurality of audio parameter delay units 104A-104G connected in series therebetween, the first audio parameter delay unit 104A being further connected to an audio parameter generator 120, a plurality of distance measure units 106A-106D, each connected to at least two of the delay units, an averaging unit 108, connected to the distance measure units, a plurality of averaging delay units 112A-112D connected in series therebetween, the first averaging delay unit 112A being further connected to the output of the averaging unit, and a digital logic unit 116 connected to the averaging delay units. In an alternative embodiment (fig 5), there is a single distance measure unit (206) coupled between a multi-stage delay unit (202) and a plurality of delay units (218) connected in series.
