A novel two-step SVM classifier for voiced/unvoiced/silence classification of speech
Fengyan Qi, Changchun Bao, Yan Liu · 2005
In this paper, a novel method for voiced/unvoiced/silence of speech classification using the support vector machine (SVM) is proposed. This classifier can correctly classify speech frames into voiced frame, unvoiced frame and silence frame. The comparison of experimental results show that the proposed method outperforms other traditional methods. The performance of SVM for different kernel functions in the experiment was analyzed and discussed as well.
