逆シャドーイング法では,シャドー音声の他に(学習者が読み上げ時に参照した)原稿を見ながら行うスクリプト・シャドー音声も別途収録し,両者の posteriorgram DTW のスコアを,自動計測された了解度スコアとして用いている.本研究では,シャドー音声の崩れの様子を考慮し,また DTW 計算において,スクリプト・シャドー音声が常に規範音声として使われることを鑑み,非対称な局所パスを導入し,精度向上を検討した.更に,学習者音声やシャドー音声に対する音声認識結果(自動書き起こし)を使うことの是非についても検討した.","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":"2021-06-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"50","bibliographicVolumeNumber":"2021-SLP-137"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
