Hands-on speaker diarization tutorial notebooks can be found under <NeMo_git_root>/tutorials/speaker_tasks.
There are tutorials for performing speaker diarization inference using MarbleNet (VAD), TitaNet, and Multi-Scale Diarization Decoder. We also provide tutorials about getting ASR transcriptions combined with speaker labels along with voice activity timestamps with NeMo ASR collections.
Most of the tutorials can be run on Google Colab by specifying the link to the notebooks’ GitHub pages on Colab.
If you are looking for information about a particular model used for speaker diarization inference, or would like to find out more about the model architectures available in the nemo_asr collection, check out the Models page.
Documentation on dataset preprocessing can be found on the Datasets page. NeMo includes preprocessing scripts for several common ASR datasets, and this page contains instructions on running those scripts. It also includes guidance for creating your own NeMo-compatible dataset, if you have your own data.
Information about how to load model checkpoints (either local files or pretrained ones from NGC), perform inference, as well as a list of the checkpoints available on NGC are located on the Checkpoints page.
Documentation for configuration files specific to the nemo_asr models can be found on the
Configuration Files page.
