Evaluating Nemotron-3-Diarization on SpokesBiz and DiaBiz
The new speaker diarization model from Nvidia looks really solid. At Voicelab we’ve just evaluated it on the multispeaker SpokesBiz (650 hours) dataset and it seems to be both more accurate and faster than Nvidia’s Sortformer v2 and PyAnnote 3.1. The results on the two-speaker phone-based DiaBiz dataset (410 hours) are more nuanced with both models from Nvidia clearly outperforming Pyannote 3.1.
