Diarization.

Speaker Diarization is the task of segmenting audio recordings by speaker labels. A diarization system consists of Voice Activity Detection (VAD) model to get the time stamps of audio where speech is being spoken ignoring the background and Speaker Embeddings model to get speaker embeddings on segments that were previously time stamped. Speaker Diarization. The Speaker Diarization model lets you detect multiple speakers in an audio file and what each speaker said. If you enable Speaker Diarization, the resulting transcript will return a list of utterances, where each utterance corresponds to an uninterrupted segment of speech from a single speaker. As per the definition of the task, the system hypothesis diarization output does not need to identify the speakers by name or definite ID, therefore the ID tags assigned to the speakers in both the hypothesis and the reference segmentation do not need to be the same.This process is called speech diarization and can be acchieved using the pyannote-audio library. This is based on PyTorch and hosted on the huggingface site. Here is some code for using it, mostly adapted from code from Dwarkesh Patel. To do this you need a recent GPU probably with at least 6-8GB of VRAM to load the medium model.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.

Channel Diarization enables each channel in multi-channel audio to be transcribed separately and collated into a single transcript. This provides perfect diarization at the channel level as well as better handling of cross-talk between channels. Using Channel Diarization, files with up to 100 separate input channels are supported.
