Speaker-Conditioned U-Shaped Diarization With Speaker Extraction-Guided Enhancement

N. Hung Anh Tran, Ngoc Chau Hoang, Quoc Cuong Nguyen

Speaker diarization demarcates speech segments by speaker, answering the question “who spoke when?”. Recently, a promising approach has emerged by integrating speaker diarization with speech separation or speaker extraction, which offers better generalization and requires significantly less pretraining data. Despite this progress, …
