However, a perfect suppression can not be confirmed because the sound source signal propagates in a spatially spread distribution. Therefore, we propose to improve the suppression performance using post-processing of the directionality forming circuit. The proposed method is based on the statistical independence of the circuit outputs to reduce the residual noise. The effectiveness of the proposed method is demonstrated through real-world experimental 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":"2024-02-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"44","bibliographicVolumeNumber":"2024-SLP-151"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":232514,"updated":"2025-01-19T10:25:20.876824+00:00","links":{},"created":"2025-01-19T01:33:25.603469+00:00"}
