Model Description

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

Model type: Voice Activity Detection

License: MIT

Parent Model: silero-vad

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

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
