Abstract

[In this chapter, the proposed two-stage VOP detection method is used for improving the Speaker Identification (SI) performance in the presence of coding. With the help of VOPs, the crucial regions of speech segments which mainly characterize speaker-specific information are determined. Features extracted from these crucial speech segments are used for speaker identification task for improving the recognition accuracy. The accurate VOPs determined from the proposed method are also explored for nonuniform time scale modification. The proposed nonuniform time scale modification method provides high quality speech while varying speech rate. In this method, vowel regions are modified nonuniformly based on the type of vowel, and consonant and transition regions are unaltered irrespective of speaking rate. Here, vowel onset points are used to determine consonant, vowel, and transition regions.]
