Abstract
The encoded speech for digital transmission systems contains semantic information and singular information. Therefore, a speech or speaker recognition system can be realized by using only the encoded speech. In this paper, we propose a speaker verification method based on a speech coding scheme in the digital transmission systems. The proposed method utilizes CELP (Code Excited Linear Prediction) parameters which are used in speech coding schemes for mobile communication systems or IP networks, and verifies a speaker only with the encoded speech. The merits of the proposed method are as follows; (1) Speaker verification is easily realized in the current mobile terminals or network systems by adding a little function. (2) Since CELP parameters contain a speaker's characteristics of articulation, text-independent speaker verification is realized. The reliability of the proposed method is discussed with some simulation results.<br>
