Abstract :
Based on its physical mechanism and enhancement of the voiced/unvoiced feature, a new method for automatic segmentation of Chinese continuous speech into voiced/unvoiced units is presented, using the wavelet transform. The accuracy and the precision are improved by using the proposed multi-threshold detector
