method based on so called zero frequency filtering method was proposed by Yegnanarayana for representing Indian stop consonants . The proposed method uses unstable IIR filters that place four poles at zero frequency and at the same time employs local mean subtracting filters to stabilize its output. This simple method was reported to run extremely fast and has comparative performance with existing F0 extractors. This article reports on a follow-up implementation of the method and evaluations and investigations for its performance and characteristics having its applicability to TANDEM-STRAIGHT and real time STRAIGHT in mind. The results indicated that the proposed method runs 7 times faster than real time with Matlab implementation on a standard laptop PC. It was also found that the gross error rate was 0.55% which is somewhat worse than the most recent methods but still reasonably high for practical applications, Finally, temporal resolution finer (namely 1/3) than instantaneous frequency based methods was also demonstrated.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"102","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"97","bibliographicIssueDates":{"bibliographicIssueDate":"2008-07-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"78(2008-MUS-076)","bibliographicVolumeNumber":"2008"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T23:19:14.894082+00:00","id":55650,"links":{}}
