Silero VAD - pre-trained enterprise-grade Voice Activity Detector (also see our STT models).

• 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 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 8000 Hz and 16000 Hz sampling rates.

• 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.

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)
