# Silero-VAD-v5 — CoreML

CoreML conversion of [Silero VAD v5](https://github.com/snakers4/silero-vad) for Apple Neural Engine.

## Model Details

| Detail | Value |
|--------|-------|
| Architecture | STFT → Conv1d encoder → LSTM → decoder |
| Parameters | ~309K |
| Input | 512 samples (32ms @ 16kHz) |
| Output | Speech probability (0.0–1.0) |
| Size | ~4.2 MB |

## Usage

```swift
let vad = try await SileroVADModel.fromPretrained(backend: .coreML)
let prob = vad.processChunk(samples)
```
