Abstract
According to one embodiment, a voice activity detection apparatus includes a processing circuit. The processing circuit acquires an acoustic signal and a non-acoustic signal, calculates an acoustic feature based on the acoustic signal, calculates a non-acoustic feature based on the non-acoustic signal, calculates a voice emphasized feature based on the acoustic signal and the non-acoustic signal, calculates a voice existence/non-existence feature on the basis of the acoustic feature and the non-acoustic feature, calculates a voice existence score based on the voice emphasized feature and the voice existence/non-existence feature, detects a voice section and/or a non-voice section based on comparison of the voice existence score with a threshold.
