In this paper we propose a method for voice activity detection (VAD) in a speech signal recorded in the presence of noise. The so-called endpoint detection (EPD), i.e., detection of voice activity (speech) boundaries is very difficult if the signal is acquired in noisy environments. The proposed VAD method uses an additional stage of wavelet subband… CONTINUE READING
