Diarization methods can be broadly divided into two categories: clustering-based and end-to-end supervised systems. The former typically employs a pipeline comprised of voice activity detec-tion (VAD), speaker embedding extraction and clustering [3–6]. End-to-end neural diarization (EEND) reformulates the task as a multi-label classification.Diarization is used in many con-versational AI systems and applied in various domains such as telephone conversations, broadcast news, meetings, clinical recordings, and many more [2]. Modern diarization systems rely on neural speaker embeddings coupled with a clustering algorithm. Despite the recent progress, speaker diarization is still onediarization performance measurement.
