| Abstract(in English) | The separation of speech and non-speech events is an important problem for speech recognition. In clean conditions, energy or zero-crossing features work well. However, a traditional voice activity detection (VAD) is not robust to noisy conditions where speech signal is seriously contaminated by noise. A robust VAD algorithm based on the determination of the speech/non-speech bispectra of the third order auto-cumulants has been proposed. In this paper, we investigate the effectiveness of the integration between MFCC and the bispectra of the third order auto-cumulants. Experimental results show the proposed algorithm effective. |
