Abstract
According to one embodiment, a voice activity detection apparatus comprises a processing circuit. The processing circuit calculates an acoustic feature based on an acoustic signal; calculates a non-acoustic feature based on a non-acoustic signal; calculates a correlation coefficient based on the acoustic feature and the non-acoustic feature; and detects a voice section and/or a non-voice section based on a comparison of the correlation coefficient with a threshold, the voice section being a time section in which voice is presence, the non-voice section being a time section in which voice is absence.
