In the proposed technique, an index for retrieving a query term consists of syllable-based confusion networks which are constructed by combining multiple outputs of speech recognizers. Although the index is robust to the speech recognition errors and the out-of-vocabulary problem, the index produces a number of false detection errors on the STD task. Therefore, we designs a simple filter which can control the false detection errors. The experiment of STD showed that our technique was very effective at detecting out-of-vocabulary terms, improving recall rate to 0.71 from the baseline.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2009-12-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"19","bibliographicVolumeNumber":"2009-SLP-79"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":67054,"updated":"2025-01-22T00:44:48.574538+00:00","links":{},"created":"2025-01-18T23:27:39.135301+00:00"}
