this paper, we propose the technique for improving the N-best candidates accuracy in a spontaneous utterance by destination setting task with car navigation, combining the N-best candidates using a grammatical constraint at sentence and the word lattice using word spotting, to improve performance in the framework of speech understanding from the N-best candidates in early research. The system calculates the reliability of the word of each utterance by using the word lattice. We use the reliability to raise the word likelihood and to exchange the word of the N-best candidate by grammatical constraint. As a result of the evaluation experiment, we raise the appearance order in the N-best candidate of the correct word by using this echnique in the sentence where the interjection and OOV words existed. We show the effectiveness of our proposed method.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"120","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"115","bibliographicIssueDates":{"bibliographicIssueDate":"2005-12-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"127(2005-SLP-059)","bibliographicVolumeNumber":"2005"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":56937,"links":{}}
