A packaged version of the Silero VAD model
Project description
Silero VAD
Silero VAD - pre-trained enterprise-grade Voice Activity Detector (also see our STT models).
Real Time Example
Key Features
-
Stellar accuracy
Silero VAD has excellent results on speech detection tasks.
-
Fast
One audio chunk (30+ ms) takes 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 one megabyte in size.
-
General
Silero VAD was trained on huge corpora that include over 100 languages and it performs well on audios from different domains with various background noise and quality levels.
-
Flexible sampling rate
Silero VAD supports 8000 Hz and 16000 Hz sampling rates.
-
Flexible chunk size
Model was trained on 30 ms. Longer chunks are supported directly, others may work as well.
-
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.
Typical Use Cases
- Voice activity detection for IOT / edge / mobile use cases
- Data cleaning and preparation, voice detection in general
- Telephony and call-center automation, voice bots
- Voice interfaces
