The feature of this system is to change speech rate as desired on real time, with invariance in pitch. We introduce some trials to apply this system to singing voice or musical sounds as well as to the broadcasting equipments. A new application of this system to a broadcasting VTR system is also demonstrated. It can maintain the pitch of audio signals when playback speed is changed between ×0.3 and ×3.0. For rush watching of the contents, the converted speech can be easy to heard. This effect is produced by both making speech rate slower at every onset of a breath group and shorting pause interval between the breath group.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"42","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"41","bibliographicIssueDates":{"bibliographicIssueDate":"1998-02-13","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"14(1997-MUS-024)","bibliographicVolumeNumber":"1998"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":56379,"links":{}}
