Voice activity detection method and apparatus

The invention provides a voice activity detection (VAD) method and apparatus. The method comprises: at least one first type characteristic parameter in a first characteristic set, at least one second type characteristic parameter in a second characteristic set, at least two existing VAD decision results are obtained, wherein the first type characteristic parameter and the second type characteristic parameter are used as characteristic parameters for VAD detection; according to the first type characteristic parameter, the second type characteristic parameter, and the at least two existing VAD decision results, voice activity detection is carried out, thereby obtaining a combined VAD decision result. With the method and apparatus, technical problems of inaccurate VAD scheme detection according to the correlation techniques can be solved; the VAD accuracy is improved; and thus the user experience is enhanced.
