The EM (Expectation Maximization) algorithm is widely used for paramete estimation of statistical models. However, the EM algorithm has the problem of initialization dependence. To relax this problem, the DAEM algorithm has been proposed. In this paper, we apply the DAEM algorithm to estimate acoustic models for speaker recognition and continuous speech recognition.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2003-12-18","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"124(2003-SLP-049)","bibliographicVolumeNumber":"2003"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":57151,"updated":"2025-01-22T04:36:29.166946+00:00","links":{}}
