Introduction
This example shows how to use the Dart API from sherpa-onnx for voice activity detection (VAD). Specifically, we use VAD to remove silences from a wave file.
Usage
dart pub get
wget https://github.com/k2-fsa/sherpa-onnx/releases/download/asr-models/silero_vad.onnx
wget https://github.com/k2-fsa/sherpa-onnx/releases/download/asr-models/lei-jun-test.wav
dart run \
./bin/vad.dart \
--silero-vad ./silero_vad.onnx \
--input-wav ./lei-jun-test.wav \
--output-wav ./lei-jun-test-no-silence.wav
It should generate a file lei-jun-test-no-silence.wav, where silences are removed.
