The conventionally proposed estimator requires the low-pass filter for extracting fundamental component from the periodic signal. Since F0 is unknown, many filters with difference cutoff frequencies are used, and then F0 candidates and their reliabilities are obtained. The estimated F0 is selected by their reliabilities. This estimator has required high-SNR speech because it depends on the SNR in lower frequency band. In this research, we introduce an algorithm for compensating for the estimated result by instantaneous frequency. This compensation can improve the noise robustness. This article shows the algorithm and carried out an evaluation in the noise robustness. The effectiveness of the proposed algorithm was discussed based on the evaluation results.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2016-01-29","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"2016-SLP-110"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:22:40.631984+00:00","id":147580,"links":{}}
