Description
Nemotron 3 Diarization is an advanced speaker diarization model developed by NVIDIA, designed to accurately determine 'who spoke when' in real-world audio scenarios. This model is capable of handling up to eight speakers simultaneously, making it ideal for complex audio environments such as meetings, podcasts, and telephonic conversations.

The model supports both streaming and offline inference, providing flexibility for different use cases. Streaming inference utilizes the Arrival-Order Speaker Cache (AOSC) and FIFO queue to maintain speaker identities over time, ensuring consistent diarization results. The model's architecture includes a 31-layer Transformer encoder with Rotary Positional Embeddings, which processes 10 ms Mel-spectrogram input features.
Nemotron 3 Diarization is optimized for NVIDIA GPU-accelerated systems, including Ampere, Ada Lovelace, Blackwell, and Hopper NVIDIA GPUs. It is integrated with the NeMo Framework, allowing for seamless deployment in AI systems. The model is trained on a diverse set of datasets, including real conversations and simulated multi-talker audio mixtures, ensuring robust performance across various audio conditions.
The model is available for commercial and non-commercial use under the OpenMDW License Agreement, version 1.1. It provides configurable output frame resolution and supports chunked inference, allowing for recordings without a fixed maximum duration. Nemotron 3 Diarization is a valuable tool for applications requiring precise speaker identification and activity tracking.
