Comparing various voice recognition techniques

摘要

In this paper we describe and compare some speaker recognition techniques. A mel-cepstral short-time analysis for speech signals is presented first. It is used in the voice feature extraction stage. Then speech-dependent and speech-independent speaker recognition approaches are proposed by us in this paper. Minimum mean-distance classification methods are used by the supervised classifier of the voice identification system. Threshold-based procedures are provided for the speaker verification part of the system.
