In the proposed method, a phoneme graph is generated at the pre-processing stage, and then the best word sequence is searched while restricting expansion of hypotheses using the information of the phoneme graph at the main recognition stage. The phoneme-graph-based restriction consists of the limitation of phoneme boundaries and the Forward-Back ward Pruning, which enable to reduce the search space dramatically. The proposed method was tested on a 5,000-word Japanese newspaper reading task. The experimental results show that this method can reduce about 70% of the elapsed time without any error increasing.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1373","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1365","bibliographicIssueDates":{"bibliographicIssueDate":"1999-04-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"40"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"大語彙連続音声認識"}]},"weko_creator_id":"1"},"id":12697,"links":{}}
