NVIDIA Nemotron 3 Diarization — “who spoke when” in real time

· Source: original

NVIDIA rolled out Nemotron 3 Diarization — real-time diarization 🎙

The product is called Nemotron 3 Diarization, and its task is specific — real-time multi-speaker diarization. The key phrasing NVIDIA itself uses to describe the task: "who spoke when."

The breakdown was published in the NVIDIA blog on the HuggingFace platform. The piece came out under the headline:

Know Who Spoke When: Build Real-Time, Multi-Speaker AI with NVIDIA Nemotron 3 Diarization

And it's structured as a build guide rather than an announcement: the blog shows how to assemble a system that distinguishes the voices of multiple speakers right in the stream.

An image is attached to the post; there is no description of it in the piece.

The date of the material in the source is 23 September 2026
