The proposed system requires neither access to\r\nmulti-channel training data nor prior knowledge about the number or placement\r\nof microphones. It works for both a compact microphone array and distributed\r\nmicrophones, with minor adjustments. Due to its superior handling of\r\noverlapping speech during segmentation, the proposed pipeline significantly\r\noutperforms the single-channel pyannote approach, both in a scenario with a\r\ncompact microphone array and in a setup with distributed microphones.\r\nAdditionally, we show that, unlike fully spatial diarization pipelines, the\r\nproposed system can correctly track speakers when they change positions.","lang":"eng"}],"file":[{"relation":"main_file","content_type":"application/pdf","file_id":"61085","file_name":"main.pdf","access_level":"open_access","file_size":921918,"date_created":"2025-08-29T09:43:32Z","creator":"cord","date_updated":"2025-08-29T09:43:32Z"}],"oa":"1","date_updated":"2025-11-10T09:06:47Z","author":[{"first_name":"Tobias","last_name":"Cord-Landwehr","id":"44393","full_name":"Cord-Landwehr, Tobias"},{"first_name":"Tobias","last_name":"Gburrek","full_name":"Gburrek, Tobias","id":"44006"},{"first_name":"Marc","full_name":"Deegen, Marc","id":"70272","last_name":"Deegen"},{"last_name":"Haeb-Umbach","full_name":"Haeb-Umbach, Reinhold","id":"242","first_name":"Reinhold"}],"doi":"10.21437/Interspeech.2025-1663","conference":{"location":"Rotterdam","name":"Interspeech 2025"},"has_accepted_license":"1","citation":{"ama":"Cord-Landwehr T, Gburrek T, Deegen M, Haeb-Umbach R.
