{"type":"preprint","_id":"57085","abstract":[{"text":"We propose an approach for simultaneous diarization and separation of meeting data. It consists of a complex Angular Central Gaussian Mixture Model (cACGMM) for speech source separation, and a von-Mises-Fisher Mixture Model (VMFMM) for diarization in a joint statistical framework. Through the integration, both spatial and spectral information are exploited for diarization and separation. We also develop a method for counting the number of active speakers in a segment of a meeting to support block-wise processing. While the total number of speakers in a meeting may be known, it is usually not known on a per-segment level. With the proposed speaker counting, joint diarization and source separation can be done segment-by-segment, and the permutation problem across segments is solved, thus allowing for block-online processing in the future. Experimental results on the LibriCSS meeting corpus show that the integrated approach outperforms a cascaded approach of diarization and speech enhancement in terms of WER, both on a per-segment and on a per-meeting level.","lang":"eng"}],"status":"public","year":"2024","language":[{"iso":"eng"}],"date_updated":"2024-11-14T09:35:37Z","author":[{"last_name":"Cord-Landwehr","id":"44393","first_name":"Tobias","full_name":"Cord-Landwehr, Tobias"},{"first_name":"Christoph","id":"40767","last_name":"Boeddeker","full_name":"Boeddeker, Christoph"},{"last_name":"Haeb-Umbach","id":"242","first_name":"Reinhold","full_name":"Haeb-Umbach, Reinhold"}],"citation":{"chicago":"Cord-Landwehr, Tobias, Christoph Boeddeker, and Reinhold Haeb-Umbach. “Simultaneous Diarization and Separation of Meetings through the Integration of Statistical Mixture Models,” 2024.","mla":"Cord-Landwehr, Tobias, et al. <i>Simultaneous Diarization and Separation of Meetings through the Integration of Statistical Mixture Models</i>. 2024.","bibtex":"@article{Cord-Landwehr_Boeddeker_Haeb-Umbach_2024, title={Simultaneous Diarization and Separation of Meetings through the Integration of Statistical Mixture Models}, author={Cord-Landwehr, Tobias and Boeddeker, Christoph and Haeb-Umbach, Reinhold}, year={2024} }","ieee":"T.
