NVIDIA has released Nemotron 3 Diarization, an open-weight speaker diarization model that determines "who spoke when" in audio, supporting both streaming and offline inference for up to eight speakers. The model achieves input buffer latency as low as 80 milliseconds and is available for commercial and non-commercial use.

NVIDIA released Nemotron 3.5 ASR, a 600M-parameter speech-to-text model supporting 40 language-locales from a single checkpoint. The model achieves 0.07 seconds to final transcript after speech ends and ranks 2nd in latency among streaming ASR models according to Artificial Analysis benchmarks.
