【Abstract】 The Mel frequency is a way to express frequency that can reflect the ability of person’s ear to sensate ronunciation of different frequency.This paper mainly introduces the characters and extracting methods of Mel frequency cepstrum coefficient(MFCC),withdrawing its first order difference parameter,so characteristic parameter can reflect the voice of the information more accurately in identifing on the person speaking,improveing the recognition rate.更多还原
