In adverse conditions, the speech recognition performance decreases in part due to imperfect speech/non-speech detection. In this paper, a new combination of voicing parameter and energy for speech/non-speech detection is described. This combination avoids especially the noise detections in real life very noisy environments and provides better performance for continuous speech recognition. This new speech/non-speech detection approach outperforms both noise statistical based  and Linear Discriminate Analysis (LDA) based  criteria in noisy environments and for continuous speech recognition applications.
