摘要：

A new fusion method for voice activity detection in additive nonstationary noise is suggested. A performance study of the methods: fusion, the recently developed geometrically adaptive energy level, periodicity measure, and zero crossings rates, is presented. The new method is shown to operate reliably down to -5 dB SNR.
