最后发布版本: v5.1 ( 2024-07-09 21:18:46)
Silero VAD
Silero VAD - pre-trained enterprise-grade Voice Activity Detector (also see our STT models).
Real Time Example

Fast start
Dependencies
System requirements to run python examples on x86-64
systems:
-
python 3.8+
; - 1G+ RAM;
- A modern CPU with AVX, AVX2, AVX-512 or AMX instruction sets.
Dependencies:
-
torch>=1.12.0
; -
torchaudio>=0.12.0
(for I/O only); -
onnxruntime>=1.16.1
(for ONNX model usage).
Silero VAD uses torchaudio library for audio I/O (torchaudio.info
, torchaudio.load
, and torchaudio.save
), so a proper audio backend is required:
- Option №1 - FFmpeg backend.
conda install -c conda-forge 'ffmpeg<7'
; - Option №2 - sox_io backend.
apt-get install sox
, TorchAudio is tested on libsox 14.4.2; - Option №3 - soundfile backend.
pip install soundfile
.
If you are planning to run the VAD using solely the onnx-runtime
, it will run on any other system architectures where onnx-runtume is supported. In this case please note that:
- You will have to implement the I/O;
- You will have to adapt the existing wrappers / examples / post-processing for your use-case.
Using pip:
pip install silero-vad
from silero_vad import load_silero_vad, read_audio, get_speech_timestamps
model = load_silero_vad()
wav = read_audio('path_to_audio_file')
speech_timestamps = get_speech_timestamps(
wav,
model,
return_seconds=True, # Return speech timestamps in seconds (default is samples)
)
Using torch.hub:
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,
return_seconds=True, # Return speech timestamps in seconds (default is samples)
)
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 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.
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
