Introduction

This folder contains script for exporting silero_vad v4 to rknn.

Steps to run

1. Download a jit model

You can download it from https://github.com/snakers4/silero-vad/blob/v4.0/files/silero_vad.jit

wget https://github.com/snakers4/silero-vad/raw/refs/tags/v4.0/files/silero_vad.jit

ls -lh silero_vad.jit
-rw-r--r-- 1 kuangfangjun root 1.4M Mar 30 11:04 silero_vad.jit

2. Export it to onnx

./export-onnx.py

It will generate a file ./m.onnx

 ls -lh m.onnx
-rw-r--r-- 1 kuangfangjun root 627K Mar 30 11:13 m.onnx

3. Test the onnx model

wget https://github.com/k2-fsa/sherpa-onnx/releases/download/asr-models/lei-jun-test.wav
./test-onnx.py  --model ./m.onnx --wav ./lei-jun-test.wav

4. Convert the onnx model to RKNN format

We assume you have installed rknn toolkit 2.1

./export-rknn.py --in-model ./m.onnx --out-model m.rknn  --target-platform rk3588

It will generate a file ./m.rknn

ls -lh m.rknn
-rw-r--r-- 1 kuangfangjun root 2.2M Mar 30 11:19 m.rknn
