TEN VAD — CoreML

TEN Framework streaming VAD converted to Apple CoreML (mlprogram, fp32 + int8 weight-quant). Feature extractor (STFT + pitch + biquad) NOT included — see upstream src/.

Upstream: https://github.com/TEN-framework/ten-vad

Part of the VAD CoreML collection — CoreML conversions of community VAD models for use in iOS / macOS apps.

File	Format	Notes
`TenVAD.mlpackage`	CoreML mlprogram (fp32)
`TenVAD_int8.mlpackage`	CoreML mlprogram (int8 weight-quant)	smaller, ~same accuracy

Outputs:

  "output_3": [

}

Preprocessing (NOT included in the CoreML graph — implement on-device): STFT + pitch + biquad feature stack from ten-vad-src/src/ (C++). NOT ported. Must port to Swift/Accelerate for iOS integration; or wrap the C sources via a thin ObjC++ bridge.

Notes: Parity validated against ONNX Runtime on 5 random input vectors (no real audio path). Graph parity is sufficient to trust the CoreML conversion; end-to-end ATC validation requires the feature extractor port.

Numerical parity vs reference

Variant	max abs diff	mean abs diff	Pearson
fp32	5.960e-08	2.384e-08	1.000000
int8	8.149e-04	4.537e-04	0.999990

Validated against vs ORT prob on 5 random inputs.

This conversion is released under the same license as the upstream model (apache-2.0). Original credits remain with the upstream authors.

Conversion

Converted with coremltools 9.0, mlprogram format, minimum_deployment_target=iOS17.
