# nemotron-speech-streaming-en-0.6b — ONNX, calibrated static int8

A calibration-based static-int8 quantization of the ONNX export of
[nvidia/nemotron-speech-streaming-en-0.6b](https://huggingface.co/nvidia/nemotron-speech-streaming-en-0.6b)
(English streaming speech recognition, 0.6B parameters).

- Peak inference memory ≈ 0.8 GB (the fp32 ONNX export runs ≈ 2.6 GB).
- Word-error rate within noise of fp32 on standard read-speech material; whispered/very-quiet
  speech degrades somewhat relative to fp32.
- Files: `encoder.onnx` + `encoder.onnx.data`, `decoder_joint.onnx`, `tokenizer.model`.
- Runs with ONNX Runtime; the encoder is cache-aware for incremental/streaming inference.
