The system archives broadcast news programs with their transcriptions and speaker tags with the aim of getting a collection of training and evaluation data for acoustic and language models.

The system has the functions of music and speech detection during dual-gender decoding, speaker diarization, and automatic language model updating for upcoming news shows. Trigram lattices are compressed into confusion networks that are indexed for known item retrieval. The system achieved a 9.2 % of word error rate and a 95 of F-measure in evaluation of known item retrieval for 53 Japanese broadcast news shows.","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":"20","bibliographicVolumeNumber":"2009-SLP-77"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":62681,"links":{}}
