Nemotron 3 Diarization#

Description#

Nemotron 3 Diarization is an open-weight speaker diarization model designed to determine "who spoke when" in real-world audio. It supports both streaming and offline inference and handles up to eight speakers. Following Sortformer [\[1\]](#ref-1), the model resolves speaker permutation by ordering its output channels according to each speaker's first arrival in the input audio.

For streaming inference, the model adopts the Arrival-Order Speaker Cache (AOSC) and FIFO queue introduced in Streaming Sortformer [\[2\]](#ref-2). The AOSC retains speaker information from earlier chunks to preserve speaker identities over time, while the FIFO queue provides recent frame context for each processing step.

A single checkpoint supports input buffer latency as low as 80 ms for latency-critical applications, although the lowest recommended configuration is 0.32 s; the offline-style configuration uses a 30.4 s input buffer. The output frame resolution is configurable in multiples of 10 ms. With chunked inference, the maximum audio duration is not limited.

This model is ready for commercial or non-commercial use.

How to use this model#

Coming soon...


Model Architecture#

Architecture Type: Transformer.

Network Architecture:

  • A 31-layer Transformer encoder with Rotary Positional Embeddings (RoPE).
  • 10 ms Mel-spectrogram input features downsampled by a factor of eight through feature stacking, producing an 80 ms encoder frame rate.
  • A Conv1D layer above the encoder that upsamples predictions to the 10 ms input-feature resolution.
  • AOSC and a FIFO queue for streaming inference.

Number of model parameters: 100M (1.0 × 10⁸).

Input#

Input Type: Audio.

Input Format: 16 kHz, single-channel audio in .wav, .flac, .opus, or .mp3 format.

Input Parameters: One-dimensional, 16 kHz, single-channel audio waveform.

Maximum Duration: Not limited when chunked inference is used.

Other Properties Related to Input: Input audio must be sampled at 16 kHz and is converted into 10 ms Mel-spectrogram features. Chunked inference supports recordings without a fixed maximum duration.

Output#

Output Type: Other: Numerical tensor.

Output Format: Float Tensor.

Output Parameters: A two-dimensional tensor with shape [T, 8], where T is the number of output frames and each value is a per-speaker activity probability in the range [0, 1].

Output Frame Resolution: The default frame stride is 10 ms and can be configured to any multiple of 10 ms, such as 30 ms, 80 ms, or 240 ms.

Speaker Ordering: The eight speaker channels are ordered by the speakers' arrival time in the input audio.

Derived Output: Speaker activity probabilities can be converted into start time, end time, and a generic speaker label, for example ["speaker1", 0.51, 12.62].

Other Properties Related to Output: The output frame resolution is configurable in multiples of 10 ms. Speaker channels are ordered by first arrival, and probabilities can be postprocessed into generic speaker labels with start and end timestamps.

The integration of foundation and fine-tuned models into AI systems requires additional testing using use-case-specific data to ensure safe and effective deployment. Following the V-model methodology, iterative testing and validation at both unit and system levels are essential to mitigate risks, meet technical and functional requirements, and ensure compliance with safety and ethical standards before deployment.

Training#

The model training was initialized with a Transformer-based NEST [\[5\]](#ref-5) SSL checkpoint. Training was performed on 8 nodes of 8×NVIDIA A100-SXM4-80GB GPUs in two stages.

  1. Offline training on simulated data only using the example script and base config.
  2. Streaming fine-tuning on a combination of real conversations and simulated mixtures using the example script and base config.

Performance Evaluation#

Important.

Use the published reference labels to reproduce these results!#

The DER scores reported in this model card were computed using the exact reference annotations identified in the Labels column above. Reference RTTMs are part of the evaluation protocol: changing the reference labels changes the measured result.

We use forced-alignment based reference labels for AMI, AliMeeting and NOTSOFAR1 because the original segment-level annotations were created primarily for transcription rather than frame-accurate diarization evaluation. These annotations may label substantial within-segment silence as speech, thereby overestimating reference speaker activity. When used for DER scoring, they can inflate missed-speech error by penalizing a diarization system for correctly predicting non-speech during those intervals. Forced alignment provides more precise speech boundaries and therefore a more appropriate and interpretable reference for frame-level diarization evaluation. Please refer to [\[4\]](#ref-4) for a detailed discussion of this annotation issue and the forced-alignment methodology.

The Forced alignment links above point to the public repositories containing the reference RTTM files used for evaluation.

Results obtained using different reference labels constitute a different evaluation protocol and are not directly comparable with the numbers reported here. Before reporting a reproduction discrepancy, score the same model outputs using the linked reference RTTMs, the listed dataset split, and the collar and overlap settings specified in the Metrics section.

Low latency1.04 s18818867144

Metrics#

Diarization Error Rate (DER): The primary metric for diarization performance, consisting of false alarm (FA), missed speech (Miss), and speaker confusion (Conf).

  • All evaluations include overlapping speech.
  • Collar tolerance is 0 s for DIHARD III Eval, AliMeeting Test, AMI Test and NOTSOFAR1 Eval.
  • Collar tolerance is 0.25 s for CALLHOME-part2.

Speaker Counting Accuracy (SCA): 1 when the predicted and ground-truth speaker counts are equal; otherwise 0. This metric does not capture the magnitude of a counting error.

Speaker Counting Mean Absolute Error (MAE): |predicted speaker count - ground-truth speaker count|. This metric is more informative than SCA because it reflects magnitude of speaker counting error.

Real-Time Factor Speedup (RTFx): total audio duration / total processing time.
