<h2 align="center">Key Features</h2>
|
|
<br/>
|
|
|
|
- **Stellar accuracy**
|
|
|
|
Silero VAD has [excellent results](https://github.com/snakers4/silero-vad/wiki/Quality-Metrics#vs-other-available-solutions) on speech detection tasks.
|
|
|
|
- **Fast**
|
|
|
|
One audio chunk (30+ ms) [takes](https://github.com/snakers4/silero-vad/wiki/Performance-Metrics#silero-vad-performance-metrics) less than **1ms** to be processed on a single CPU thread. Using batching or GPU can also improve performance considerably. Under certain conditions ONNX may even run up to 4-5x faster.
|
|
|
|
- **Lightweight**
|
|
|
|
JIT model is around two megabytes in size.
|
|
|
|
- **General**
|
|
|
|
Silero VAD was trained on huge corpora that include over **6000** languages and it performs well on audios from different domains with various background noise and quality levels.
|
|
|
|
- **Flexible sampling rate**
|
|
|
|
Silero VAD [supports](https://github.com/snakers4/silero-vad/wiki/Quality-Metrics#sample-rate-comparison) **8000 Hz** and **16000 Hz** [sampling rates](https://en.wikipedia.org/wiki/Sampling_(signal_processing)#Sampling_rate).
|
|
|
|
- **Highly Portable**
|
|
|
|
Silero VAD reaps benefits from the rich ecosystems built around **PyTorch** and **ONNX** running everywhere where these runtimes are available.
|
|
|
|
- **No Strings Attached**
|
|
|
|
Published under permissive license (MIT) Silero VAD has zero strings attached - no telemetry, no keys, no registration, no built-in expiration, no keys or vendor lock.

<h2 align="center">Fast start</h2>
|
|
<br/>
|
|
|
|
```python3
|
|
import torch
|
|
torch.set_num_threads(1)
|
|
|
|
model, utils = torch.hub.load(repo_or_dir='snakers4/silero-vad', model='silero_vad')
|
|
(get_speech_timestamps, _, read_audio, _, _) = utils
|
|
|
|
wav = read_audio('path_to_audio_file')
|
|
speech_timestamps = get_speech_timestamps(wav, model)
|
|
```
