The speaker recognition system has a better prospect and can be applied widely, but, at present, almost all the speaker recognition systems are text-dependent. Although there pour out some text-independent speaker recognition systems, most of them have critical restrictions on the testing content. That is to say, they are not really text-independent. So, this paper aims to find a method to realize text-independent speaker recognition systems. At first, we use hidden Markov Model to denoise. The wavelet anal...
