The immediate upstream source is [onnx-community/silero-vad](https://huggingface.co/onnx-community/silero-vad); the original model is from the Silero team (snakers4/silero-vad on GitHub). This is not a newly trained model. ## Source | Field | Value | |---|---| | Upstream model | [onnx-community/silero-vad](https://huggingface.co/onnx-community/silero-vad) | | Upstream source revision | `e71cae966052b992a7eca6b17738916ce0eca4ec` | | Export tool/script | Mirrored from onnx-community (no re-export) | | Quantization recipe | Pre-quantized INT8 ONNX mirrored from `onnx/model_int8.onnx` | | Original model | [snakers4/silero-vad](https://github.com/snakers4/silero-vad) (GitHub) | ## Files | File | Size | Description | |---|---|---| | `onnx/model_int8.onnx` | ~624 KB | INT8 ONNX model | ## Intended Use Voice activity detection for local inference via ONNX Runtime. The INT8 variant is the CPU/low-resource build: smaller and faster on CPU than the FP16 variant. The FP16 variant is in [`tonythethompson/silero-vad-fp16-onnx`](https://huggingface.co/tonythethompson/silero-vad-fp16-onnx). Silero VAD is language-agnostic and works across a wide range of languages. ## Runtime Notes - Designed for ONNX Runtime compatible runtimes. - Expected input: 16 kHz mono audio (Silero VAD requirement). - INT8 is broadly compatible across CPU hardware (x86-64, ARM). Validate on the target execution provider before production use. ## Precision and Packaging Export tooling, precision, and quantization are recorded in the **Source** table above. This packaging mirror does not publish independent parity benchmarks; validate on your target execution provider before production use. ## Limitations - Requires 16 kHz mono audio input; other sample rates must be resampled. - INT8 may reduce detection sensitivity at the margins (very quiet or very short speech). - No repository-specific VAD quality benchmark is documented here. ## License [MIT](https://choosealicense.com/licenses/mit/) — inherited from `onnx-community/silero-vad` and the original Silero VAD model. This packaging repo adds no new license terms.
