Abstract
MFCC features are widely used in speaker recognition. However, MFCC is not suitable for identifying a speaker since they should be located in high frequency regions, while the Mel scale gets coarser in the higher frequency bands. The speaker individual information, which is nonuniformly distributed in the high frequencies, is equally important for speaker recognition; accordingly, wavelet-based features are more appropriate than MFCC.
