| # Silero VAD — INT8 ONNX
|
|
|
| INT8-quantized ONNX export of Silero VAD, an open-weight voice activity detection model.
|
| 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.

|
|
|
| ## 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.
