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."}],"file":[{"content_type":"application/pdf","relation":"main_file","date_updated":"2025-08-29T09:43:32Z","date_created":"2025-08-29T09:43:32Z","creator":"cord","file_size":921918,"file_id":"61085","file_name":"main.pdf","access_level":"open_access"}],"external_id":{"arxiv":["2506.16228"]},"ddc":["000"],"language":[{"iso":"eng"}],"has_accepted_license":"1","citation":{"apa":"Cord-Landwehr, T., Gburrek, T., Deegen, M., &#38; Haeb-Umbach, R.
