| Abstract(in English) | In conventional speaker recognition methods based on MFCC, phase information has been ignored. In this paper, we propose original phase information and a modified feature parameter obtained from the original phase information, and integrate the phase information with MFCC on a speaker identification/verification method. The speaker identification/verification experiments were performed using NTT database which consists of sentences uttered by 35 Japanese speakers (22 males and 13 females) with normal, fast and slow speaking modes on five sessions. Each speaker uttered only 5 utterances at a normal speaking mode (about 20 seconds in total) for training data. Although the phase information based method worked worse than MFCC based method, it had some ability of speaker identification. By integrating the phase information with the MFCC, the speaker identification error rate was remarkably reduced for all speaking rates in comparison with a standard MFCC-based method. The proposed modified phase information was more robust than the proposed original phase information for all speaking modes. |
