The extraction of parameters reflecting the characteristics of speaker's speech signal is the key to voiceprint recognition.MEL cepstrum coefficient(MFCC) and extraction method was introduced in this paper.On this basis,the first difference(△MFCC) was put forward.MFCC and △MFCC were combined to conduct an experiment of parameter extraction from voiceprint recognition.The results show that the extraction combining MFCC with △MFCC is superior to the independent MFCC.
