We focus on meaningful non-verbal audible reactions which suggest hot spots such as laughter and reactive tokens. In order to detect this kind of short events and segment the counterpart utterances, we need accurate audio segmentation and classification, dealing with various recording environments and background music. Thus, we propose a method for automatically estimating and switching penalty weights for the BIC-based segmentation depending on background environments. Experimental results show significant improvement in detection accuracy by the proposed method compared to when using a constant penalty weight.","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":"2009-07-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"24","bibliographicVolumeNumber":"2009-SLP-77"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:24:35.633366+00:00","updated":"2025-01-22T02:31:16.051164+00:00"}
