| Research Abstract |
This study aimed to extract of residence information of speakers using speech features originating in vocal tract resonance, and local classification of speakers. We extracted the features which made residence information distance between speakers acquired by cepstrum , and speaker distribution showed the possibility of the classification by residence information of speakers.
