چکیده |
Normalization methods are used to improve accuracy in speaker verification systems. In this paper, some of the
most usual normalization methods including maximum, TNorm, and ZNorm normalization methods were investigated
on GMM speaker modeling approach. Maximum normalization method was shown to have the best accuracy among the
studied methods. Also, hybrids of normalization methods led to better speaker verification accuracy. In this paper, serial
hybrid of normalization methods was also considered. It was shown that applying Maximum normalization method for
two successive times leads to the best result. Serial hybrid approach increased recognition time. So we proposed twostage
normalization approach that has special consideration on accuracy and recognition time of speaker verification
system. |
