The utilization of a more general prior distribution with its online adaptive estimation is shown to be effective for speeech spectral estimation in noisy environments. We tested the proposed algorithm in an in-car speech database and this significantly improved the speech recognition performance, particularly under nonstationary noise conditions such as music, air-conditioner and open window.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_18_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/10407"}]},"item_18_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"INTELLIGENT MEDIA INTEGRATION  NAGOYA UNIVERSITY / COE","subitem_publisher_language":"en"}]},"item_18_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_18_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takeda, Kazuya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"24352","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Itakura, Fumitada","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"24353","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tran, Huy Dat","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"24354","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-19"}],"displaytype":"detail","filename":"4th_p45-48.pdf","filesize":[{"value":"261.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"4th_p45-48.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/8656/files/4th_p45-48.pdf"},"version_id":"312b6c9d-2c5a-4f38-bad2-8122fc956e48"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"MULTICHANNEL SPEECH ENHANCEMENT BASED ON GENERALIZED GAMMA PRIOR DISTRIBUTION WITH ITS ONLINE ADAPTIVE ESTIMATION","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MULTICHANNEL SPEECH ENHANCEMENT BASED ON GENERALIZED GAMMA PRIOR DISTRIBUTION WITH ITS ONLINE ADAPTIVE ESTIMATION","subitem_title_language":"en"}]},"item_type_id":"18","owner":"1","path":["1038"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-08-20"},"publish_date":"2008-08-20","publish_status":"0","recid":"8656","relation_version_is_last":true,"title":["MULTICHANNEL SPEECH ENHANCEMENT BASED ON GENERALIZED GAMMA PRIOR DISTRIBUTION WITH ITS ONLINE ADAPTIVE ESTIMATION"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T05:17:16.419279+00:00"}
