Non-native speakers tend to substitute native-language’s phones for non-native phones, therefore the recognition system must use bilingual phone models consist of all phones in non-native and native languages. Speaker adaptation, generally, use utterance of the same language as the phone model. However, non-native speaker can't speak well to use speaker adaptation. In order to adapt bilingual phone models, we propose a speaker adaptation method of bilingual phone models using native speaker's utterance. To improve bilingual phone models, we propose a method using bilingual speakers' speech. Experiments showed that the bilingual phone models adapted by the proposed method outperformed the models adapted by conventional methods.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"90","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"85","bibliographicIssueDates":{"bibliographicIssueDate":"2003-12-18","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"124(2003-SLP-049)","bibliographicVolumeNumber":"2003"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":57165,"links":{}}
