The dynamic property of the melodic contour, i.e. fundamental frequency (F0) sequence, is assumed to be the main cue of singing styles because typical ornamentations such as vibrato has an individuality. F0 signal trajectories in the phase plane are used as the basic representation. By fitting Gaussian mix-ture models to the observed F0 trajectories in the phase plane, a parametric representation is obtained by a set of GMM parameters. The effectiveness of the proposed method is confirmed through experimental evaluation where 96% accuracy for singer-class discrimination was obtained.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2009-07-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2009-MUS-81"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":62618,"links":{}}
