“…In particular, the problem becomes quite serious when the techniques of neural computing with timedelay [6,8,9,13,62] are used. On the other hand, several kinds of classifiers have been also applied in speaker identification [9,18,24,28,49,63]. These classifiers include distance classifiers [3,4,25,33,42], neural network classifiers [6,7,8,11,12,13,14,19,32,46,47,54] and classifiers based upon parametric or non-parametric density estimation [28,29,52,57,59].…”
