Voice User Authentication in IP-Telephony Networks

P. M. Sulima


Various problems are considered of the voice users authentication in IP-telephony networks. Estimation is made of the influence of various factors on the recognizability of a speaker, and the decisive role of vocal codecs is shown. In such circumstances, an analysis of the pecularities of the vocal signal conversion in IP networks, the evaluation of the degree of the influence of the pecularities on the characteristics of the speaker's individuality, and the determination of the ways of the adaptation of the methods and algorithms to the vocal-signal class being considered are necessary for a speaker identification.
