{"quality_controlled":"1","language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"Recent speaker diarization studies showed that integration of end-to-end neural diarization (EEND) and clustering-based diarization is a promising approach for achieving state-of-the-art performance on various tasks. Such an approach first divides an observed signal into fixed-length segments, then performs {\\it segment-level} local diarization based on an EEND module, and merges the segment-level results via clustering to form a final global diarization result. The segmentation is done to limit the number of speakers in each segment since the current EEND cannot handle a large number of speakers. In this paper, we argue that such an approach involving the segmentation has several issues; for example, it inevitably faces a dilemma that larger segment sizes increase both the context available for enhancing the performance and the number of speakers for the local EEND module to handle. To resolve such a problem, this paper proposes a novel framework that performs diarization without segmentation. However, it can still handle challenging data containing many speakers and a significant amount of overlapping speech. The proposed method can take an entire meeting for inference and perform {\\it utterance-by-utterance} diarization that clusters utterance activities in terms of speakers. To this end, we leverage a neural network training scheme called Graph-PIT proposed recently for neural source separation. Experiments with simulated active-meeting-like data and CALLHOME data show the superiority of the proposed approach over the conventional methods."}],"doi":"10.21437/Interspeech.2022-11408","publication_status":"published","department":[{"_id":"54"}],"status":"public","author":[{"full_name":"Kinoshita, Keisuke","last_name":"Kinoshita","first_name":"Keisuke"},{"full_name":"von Neumann, Thilo","orcid":"https://orcid.org/0000-0002-7717-8670","last_name":"von Neumann","id":"49870","first_name":"Thilo"},{"last_name":"Delcroix","full_name":"Delcroix, Marc","first_name":"Marc"},{"first_name":"Christoph","id":"40767","last_name":"Boeddeker","full_name":"Boeddeker, Christoph"},{"first_name":"Reinhold","id":"242","last_name":"Haeb-Umbach","full_name":"Haeb-Umbach, Reinhold"}],"type":"conference","conference":{"name":"Interspeech 2022"},"date_created":"2022-10-28T12:07:57Z","date_updated":"2025-02-12T09:09:05Z","page":"1486-1490","year":"2022","title":"Utterance-by-utterance overlap-aware neural diarization with Graph-PIT","citation":{"ama":"Kinoshita K, von Neumann T, Delcroix M, Boeddeker C, Haeb-Umbach R.
