| Abstract(in English) | The encoded speech for mobile phone networks and IP networks conveys not only semantic information but also the information of the speaker. In this paper, we propose a speaker verification method based on CELP (Code Excited Linear Prediction)speech coding scheme. The proposed method utilezes CELP parameters which are used in speech coding schemes for mobile phone networks or IP netrowks, and verifies a speaker only with the encoded speech. The merits of the proposed method are as follows; (1) Utilizing CELP coding process, the proposed method can be applied to mobile terminals and network systems which have limited resources by adding a little function. (2) Since CELP parameters contain a speaker's characteristics of articulation, text-indepenent speaker verification is realized. An Evaluation under noisy conditions shows that proposed method is reliable in actual environment. |
