A new noise estimation method is derived in which the noise is assumed to be white. By using the property that a white noise spectrum is flat, high frequency components of a noisy speech spectrum are averaged and the standard deviation of the noise is estimated. This operation is performed in the analysis segment, thus the spectral subtraction method combined with the new noise estimation method does not need non-speech segments and as a result can adapt to non-stationary noise conditions. The effectiveness of the proposed spectral subtraction method is confirmed by experiments.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"copyright(c)2002 IEICE\n許諾番号：07RB0174　\nhttp://www.ieice.org/jpn/trans_online/index.html","subitem_description_type":"Other"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人電子情報通信学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168508","subitem_source_identifier_type":"ISSN"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"YAMAUCHI, Junpei"},{"subitem_text_value":"SHIMAMURA, Tetsuya"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1003098"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学工学部情報工学科"},{"subitem_text_value":"埼玉大学大学院理工学研究科数理電子情報部門情報システム工学領域"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Department of Information and Computer Sciences, Saitama University"},{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2002-3"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"YAMAUCHI, Junpei"},{"creatorName":"ヤマウチ, ジュンペイ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"島村, 徹也"},{"creatorName":"シマムラ, テツヤ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1003098.pdf","filesize":[{"value":"754.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1003098.pdf","url":"https://sucra.repo.nii.ac.jp/record/12905/files/A1003098.pdf"},"version_id":"3eee878b-c6ad-4aac-ba3f-622cf58b33c1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"spectral subtraction","subitem_subject_scheme":"Other"},{"subitem_subject":"noise estimation","subitem_subject_scheme":"Other"},{"subitem_subject":"high-frequency regions","subitem_subject_scheme":"Other"},{"subitem_subject":"non-stationary noise condition","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Noise Estimation Using High Frequency Regions for Spectral Subtraction","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Noise Estimation Using High Frequency Regions for Spectral Subtraction"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-10-04"},"publish_date":"2007-10-04","publish_status":"0","recid":"12905","relation_version_is_last":true,"title":["Noise Estimation Using High Frequency Regions for Spectral Subtraction"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-16T09:23:57.942915+00:00"}
