Abstract :
A system of voiceprint identification under the Internet environment is discussed in this paper. Considering the limited storages of clients and the features of network transmission, Client/Server model is adopted in the system. In the client-side, feature parameters are extracted. This paper analyzes the performances with different parameters, and a new parameter (WPTMFC) and a mixed parameter under fisher criterion are given. After comparing recognition model of GMM and LSSVM, we choose LSSVM for the server and the process of recognition is performed. The final results show that the system has good recognition rate and is feasible for the practical applications.
