Since an ASR system transcribes all of speech input, including redundant spoken expressions, resulting captions are very long and thus hard to read and understand. To solve this problem, we propose a “condensation” method, which reduces unnecessary expressions in ASR results as much as possible while retaining key meaning of the utterances. Specifically, each word in ASR results is classified into a content word or a dependent word. Basically, the latter is deleted, while the former is retained for captions. However, there are exceptions in this principle, thus we further introduce refinement process. Redundant content words to be deleted are determined using occurrence counts in annotated training data. On the other hand, for recovery of dependent words, we investigate three methods: occurrence counts in annotated training data, linguistic likelihood measure calculated by an N-gram language model, and a machine learning framework. In an experiment over real lecture transcriptions, word-based compression rate of 64% and accuracy of 78% was obtained.","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":"2016-07-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"2016-SLP-112"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:40:36.727037+00:00","updated":"2025-01-20T08:49:20.967932+00:00"}
