“Who spoke when?” from multi-party interactions such as meetings and poster presentations is valuable for adding metadata to the recordings or analyzing the discourse-structures of the multi-party interactions. To realize this function, we first detect speech periods from the observed signals (speech activity detection), and then classify the speech periods by its speakers (speaker diarization). In this paper, we adopt a speech activity detection method and a speaker diarization method to the recordings of poster sessions. The speech activity method performs based on the ratios of periodic and aperiodic components of observed signals. The speaker diarization method utilizes the direction of arrival estimation of the detected speech signals obtained from a microphone array. This paper reports preliminary results obtained from these methods.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"222","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"217","bibliographicIssueDates":{"bibliographicIssueDate":"2007-12-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"129(2007-SLP-069)","bibliographicVolumeNumber":"2007"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T04:49:21.945403+00:00","created":"2025-01-18T23:20:07.867325+00:00","id":56791}
