BLEU を用いた．対象ドメインの音声認識結果を翻訳した結果，誤り付きのパラレルコーパスを学習コーパスへ加えることにより，最大で 10.0 (BLEU) を得ることができ，ベースラインの 7.7 (BLEU) を上回った．また，学生を対象に，翻訳対象の講義音声の書き起こしと音声の翻訳実験を行い，機械による音声認識と翻訳結果との比較を行った．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2016-12-13","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"18","bibliographicVolumeNumber":"2016-SLP-114"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":176404,"updated":"2025-01-20T05:53:00.086106+00:00","links":{},"created":"2025-01-19T00:46:03.236501+00:00"}
