NVIDIA Nemotron 3 Diarization Tutorial for Real-Time Multi-Speaker AI
**Know Who Spoke When: Build Real-Time, Multi-Speaker AI with NVIDIA Nemotron 3 Diarization**
Diarization plus transcription in a real-time setup is the hard part of meeting bots, call analytics and podcast tools, and this tutorial reduces the integration work to a reproducible recipe. Developers building voice products can follow it to ship speaker-labelled transcripts without assembling the pipeline from scratch. NVIDIA's stack competes with AssemblyAI and Deepgram on speaker identification, and the Hugging Face hosting makes it easy to benchmark against those alternatives.
NVIDIA published a tutorial on 2026 covering Nemotron 3 Diarization, a system that identifies who is speaking at what time in an audio stream.
The guide walks through building real-time multi-speaker pipelines on the Hugging Face platform.It combines speaker diarization with transcription to produce speaker-labelled transcripts.
The tutorial offers a reproducible implementation path for developers.
