parakeet-tdt-0.6b-v3-int8

INT8 ONNX build of nvidia/parakeet-tdt-0.6b-v3 for sherpa-onnx. Muniment builds these files from NVIDIA's NeMo checkpoint and ships them in its products. No third-party conversion is an input to this build.

Files

SHA256SUMS carries the same four lines.

Provenance

The build asserts both pinned revisions before it installs dependencies or produces any file. It fails if either assertion fails.

Verify

sha256sum -c --strict SHA256SUMS

Attribution and statement of changes

This repository distributes a modified form of nvidia/parakeet-tdt-0.6b-v3 by NVIDIA, licensed under CC BY 4.0. The same licence applies here.

Changes made to the original work:

1. Exported NVIDIA's NeMo checkpoint to ONNX with the pinned sherpa-onnx tooling.
2. Applied dynamic INT8 weight quantization to the exported graphs.
3. Added sherpa-onnx metadata to the exported models.

No weights were retrained, merged, pruned, or otherwise altered. Recognition behavior follows the upstream model, subject to quantization loss.

The sherpa-onnx conversion tooling is licensed under Apache-2.0.

Note on identical bytes

Three of these four files are byte-identical to the widely used csukuangfj/sherpa-onnx-nemo-parakeet-tdt-0.6b-v3-int8 conversion. The encoder differs. Identical bytes do not transfer that conversion's licence status, which is undeclared. These files are built from NVIDIA's CC BY 4.0 checkpoint with Apache-2.0 tooling, and the pinned revisions above establish their provenance independently.
