The conventional AR mixture density model can be applied to modeling a quasi-stationary Gaussian AR process. However, it cannot model spectral zeros. In contrast, the proposed model is based on a frequency-warped exponential (EX) model. Accordingly, it can represent spectral poles and zeros with equal weights, and, furthermore, the model spectrum has a high resolution at low frequencies. The parameter estimation algorithm for the proposed model was also derived based on an EM algorithm. Experimental results show that the proposed model has better performance than the AR mixture density model for modeling a frequency-warped EX process.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"familyNames":[{"familyName":"Tokuda","familyNameLang":"en"},{"familyName":"徳田","familyNameLang":"ja"},{"familyName":"トクダ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Keiichi","givenNameLang":"en"},{"givenName":"恵一","givenNameLang":"ja"},{"givenName":"ケイイチ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"464","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000020217483","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000020217483"}],"names":[{"name":"Tokuda, Keiichi","nameLang":"en"},{"name":"徳田, 恵一","nameLang":"ja"},{"name":"トクダ, ケイイチ","nameLang":"ja-Kana"}]},{"nameIdentifiers":[{"nameIdentifier":"3028","nameIdentifierScheme":"WEKO"}],"names":[{"name":"北村, 正"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Institute of Electronics, Information and Communication Engineers","subitem_publisher_language":"en"}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0916-8508","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"item_10001_source_id_32","attribute_value_mlt":[{"subitem_source_identifier":"AA10826239","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takahashi, Toru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"17341","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Tokuda, Keiichi","creatorNameLang":"en"},{"creatorName":"徳田, 恵一","creatorNameLang":"ja"},{"creatorName":"トクダ, ケイイチ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Tokuda","familyNameLang":"en"},{"familyName":"徳田","familyNameLang":"ja"},{"familyName":"トクダ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Keiichi","givenNameLang":"en"},{"givenName":"恵一","givenNameLang":"ja"},{"givenName":"ケイイチ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"464","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000020217483","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000020217483"}]},{"creatorNames":[{"creatorName":"Kobayashi, Takao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"10746","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Tadashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3028","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":"2017-01-25"}],"displaytype":"detail","filename":"E86-A_1971.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","license_note":"Copyright (c) 2003 IEICE　http://search.ieice.org/index.html","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/5153/files/E86-A_1971.pdf"},"version_id":"766e9d02-493e-426e-9d24-40e2e6a3cde5"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Mixture Density Models Based on Mel-Cepstral Representation of Gaussian Process","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mixture Density Models Based on Mel-Cepstral Representation of Gaussian Process","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"91","path":["31"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-11-07"},"publish_date":"2012-11-07","publish_status":"0","recid":"5153","relation_version_is_last":true,"title":["Mixture Density Models Based on Mel-Cepstral Representation of Gaussian Process"],"weko_creator_id":"91","weko_shared_id":-1},"updated":"2025-03-19T05:06:02.651585+00:00"}
