This package aims to provide an accurate, user-friendly voice activity detector (VAD) that runs in the C++. It runs Silero VAD [1] using ONNX Runtime C++.

Code are tested in the environments bellow, feel free to try others.

• C++ 17 or above
• onnxruntime-1.12.1 or above
• cmake-3.5 or above
• SDL2 or above for examples

To use the VAD via a script tag in the browser, include the following script tags:

#include <silero_vad/vad.hpp>

silero_vad::SileroVAD vad("model/silero_vad.onnx");
std::vector<float> input_wav(vad.GetFrameSamples(), 0.0f);
bool running = true;

while(running){
  //Fill input_wav with audio samples
  bool b = vad.Detect(input_wav);
  if(b){
    //Detect voice activity in this frame
  }else{
    //No voice activity in this frame
  }
}

#Install dependencies
brew install onnxruntime
brew install sdl2

cd {silero_vad_cpp}
# Build the example
mkdir build
cd build
cmake ..
make
cd ..
# Run the example
./build/silero_vad_cpp_example
