However, there is no one-to-one mapping of positions in space to speakers if speakers move. Here, we address this by proposing a novel joint spatial and spectral mixture model, whose two submodels are loosely coupled by modeling the relationship between speaker and position index probabilistically. Thus, spatial and spectral information can be jointly exploited, while at the same time allowing for speakers speaking from different positions. Experiments on the LibriCSS data set with simulated speaker position changes show great improvements over tightly coupled subsystems."}],"date_created":"2026-05-11T14:20:48Z","keyword":["mixture models","meeting processing","diarization","source separation"],"type":"conference","department":[{"_id":"54"},{"_id":"1063"}],"title":"Loose Coupling of Spectral and Spatial Models for Multi-Channel Diarization and Enhancement of Meetings in Dynamic Environments","year":"2026","author":[{"full_name":"Meise, Adrian Tobias","last_name":"Meise","first_name":"Adrian Tobias","id":"79268"},{"full_name":"Cord-Landwehr, Tobias","first_name":"Tobias","last_name":"Cord-Landwehr","id":"44393"},{"id":"40767","full_name":"Boeddeker, Christoph","last_name":"Boeddeker","first_name":"Christoph"},{"full_name":"Delcroix, Marc","last_name":"Delcroix","first_name":"Marc"},{"first_name":"Tomohiro","last_name":"Nakatani","full_name":"Nakatani, Tomohiro"},{"full_name":"Haeb-Umbach, Reinhold","last_name":"Haeb-Umbach","first_name":"Reinhold","id":"242"}],"date_updated":"2026-05-15T08:17:25Z","main_file_link":[{"url":"https://arxiv.org/pdf/2601.16077","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.1109/icassp55912.2026.11463540"},{"extern":"1","quality_controlled":"1","citation":{"ama":"Schröder A, Röper M, Wübben D, Matthiesen B, Popovski P, Dekorsy A.
