What happened and what to do
In an announcement published on September 23, 2026, NVIDIA presented Nemotron 3 Diarization. The model identifies who spoke and at what time, handles overlapping speech, supports up to eight speakers, and has 100 million parameters. The company says the model is available for evaluation; the distribution platform's name is not reproduced here.
For a company transcribing meetings or calls, diarization can help associate audio segments with speakers and organize transcript review. A project could evaluate the model with authorized recordings, measure errors in overlapping speech, and implement a processing and monitoring pipeline while respecting audio-data privacy and security requirements.
