The well known fact is that the performance of the Speech Recognition System degrades drastically in Adverse Environments. Additive noise is one of the major element of adverse noisy environment. Detecting voiced, un-voiced or silent speech signal in noisy environment is not an easy task. A voice activity detector (VAD) is effective when the noise is stationary; it often fails when the noise statistics change during speech presence. Moreover, accurate voice activity detection under very low… CONTINUE READING
