Diarization

Without speaker diarization, we cannot distinguish the speakers in the transcript generated from automatic speech recognition (ASR). Nowadays, ASR combined with speaker diarization has shown immense use in many tasks, ranging from analyzing meeting transcription to media indexing.

diarization technologies, both in the space of modularized speaker diarization systems before the deep learning era and those based on neural networks of recent years, a proper group-ing would be helpful.The main categorization we adopt in this paper is based on two criteria, resulting total of four categories, as shown in Table1.Speaker diarization is the task of segmenting audio recordings by speaker labels and answers the question "Who Speaks When?".
