Modified Mfcc for Speaker Recognition

in this research is described a method for feature extraction from the signal that is based on the MFCC analysis. The researchers discover that the major fraction of the speech information is in the low frequency and the information in high frequency is very rubbish. So they make a method that emphasizes the low frequency of a signal. In this method the emphasis is done using MEL-frequency filter bank that the filter bank is wrought from some band pass filter and we convert the filters in this filter bank to low pass filter and compare the MODMFCC with MFCC
