A CoreML implementation of the Silero Voice Activity
Detection (VAD) model, optimized for Apple platforms
(iOS/macOS). This repository contains pre-converted
CoreML models ready for use in Swift applications.

See FluidAudio Repo link at the top for more information

## Model Description

**Developed by:** Silero Team (original), converted by
FluidAudio

**Model type:** Voice Activity Detection

**License:** MIT

**Parent Model:**
[silero-vad](https://github.com/snakers4/silero-vad)


This is how the model performs against the silero-vad v6.0.0 basline Pytorch JIT version

![graphs/yc_256ms_comparison_20250915_205721_2c04b81.png](graphs/yc_256ms_comparison_20250915_205721_2c04b81.png)

Note that we tested the quantized versions, as the model is already tiny, theres no performance imporvement at all. 


This is how the different models compare in terms of speed, the 256s takes in 8 chunks of 32ms and processes it in batches so its much faster
