# 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
|
|
|
|
```bash
|
|
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.
