Abstract (in Japanese) (See Japanese page) 
(in English) Speaker recognition technology has been applied to achieve a variety of tasks such as minute taking and speaker search for a discussion and a meeting. In conventional studies, a speaker model trained in consideration of individuality has been mainly used to read speech. However, an influence on recognition accuracy with differences of speaking style has not been fully studied in the speaker recognition. Thus, we analyzed the influence on recognition accuracy with differences of speaking style from a viewpoint of within-speaker variance and between-speaker variance for lecture speech. We also applied a divided UBM, a LDA to distributions of UBM, and a LDA to a feature space of UBM as speaker recognition methods in consideration of differences of speaking style and evaluated an effectiveness of these methods compared with conventional UBM-MAP method.
