Silero VAD v5
Browser-ready import artifacts for voice-activity-detection, produced by SkillSafe's
reproducible converter (models/ in skillsafe.ai)
from a pinned upstream source. Every byte here is derivable from that source plus
the recipe below; nothing was edited by hand.

registry files are parameter files served from models.skillsafe.ai once vetted;
bundle files ship inside an app; registry-shared is a runtime library reused by
every model of the same architecture.
Verification
Imported as published upstream (no conversion). Each file is pinned by SHA-256 to its source; every ONNX file passed onnx.checker and a CPU smoke run under onnxruntime with zero-filled inputs at the declared shapes:
| file | inputs | outputs | ms |
|---|---|---|---|
silero_vad.onnx | input[1, 576], state[2, 1, 128], sr[] | output[1, 1], stateN[2, 1, 128] | 0.3 |
silero_vad_half.onnx | input[1, 576], state[2, 1, 128] | output[1, 1], stateN[2, 1, 128] | 0.2 |
Use in the browser
import * as ort from "onnxruntime-web";
const session = await ort.InferenceSession.create("https://huggingface.co/skillsafe-ai/silero-vad/resolve/main/silero_vad.onnx", { executionProviders: ["webgpu", "wasm"] });
Contract (silero_vad.onnx): input input float32 ['?', '?'], state float32 [2, '?', 128], sr int64 [] → output output float32 ['?', 1], stateN float32 ['?', '?', '?']. Opset 16.
