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
