An Evaluation on Recognition Accuracy Rate of Speaker Identification System Using Spectral Ratio between Air-Transmitted Speech Sounds and Bone-Transmitted Speech Sounds

Abstract

Up to now, a speaker identification method using MFCC spectral ratio between air-transmitted speech sounds and bone-transmitted speech sounds, has been proposed. However, the recognition accuracy rate of this method which is applied to many speakers, has not been shown. This paper shows that the proposed method is useful to identify many speakers using MFCC spectral ratio by the experiment with 70 speakers.
