paper proposes the improvement method based on one-to-many eigenvoice conversion (EVC) for sound quality and speaker individuality of three types of alaryngeal speech: esophageal speech; electrolaryngeal speech; and body-conducted silent electrolaryngeal speech. Although alaryngeal speech allows laryngectomees to utter speech sounds, it suffers from lack of naturalness and speaker individuality. To improve the sound quality of alaryngeal speech, alaryngeal-speech-to-speech (AL-to-Speech) methods based on statistical voice conversion have been proposed. This paper further applies one-to-many EVC capable of flexibly adapting the conversion model to given target natural voices to the AL-to-Speech methods for recovering speaker individuality of alaryngeal speech. The experimental results of objective and subjective evaluations demonstrate that the proposed methods yield significant improvements of speech quality and make the converted voice quality similar to the given target voice quality.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2010-SLP-82"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":69900,"updated":"2025-01-21T23:42:40.850430+00:00","links":{},"created":"2025-01-18T23:29:14.936143+00:00"}
