Silero VAD

Single Image Why our VAD is better than WebRTC

Silero VAD: pre-trained enterprise-grade Voice Activity Detector (VAD), Number Detector and Language Classifier. Enterprise-grade Speech Products made refreshingly simple (see our STT models).

Currently, there are hardly any high quality / modern / free / public voice activity detectors except for WebRTC Voice Activity Detector (link).

Also in enterprise it is crucial to be able to anonymize large-scale spoken corpora (i.e. remove personal data). Typically personal data is considered to be private / sensitive if it contains (i) a name (ii) some private ID. Name recognition is highly subjective and would depend on locale and business case, but Voice Activity and Number detections are quite general tasks.

Key features:

• Modern, portable;
• Lowe memory footprint;
• Superior metrics to WebRTC;
• Trained on huge spoken corpora and noise / sound libraries;
• Slower than WebRTC, but fast enough for IOT / edge / mobile applications;

Typical use cases:

• Spoken corpora anonymization;
• Voice activity detection for IOT / edge / mobile use cases;
• Data cleaning and preparation, number and voice detection in general;

Getting Started

The models are small enough to be included directly into this repository. Newer models will supersede older models directly.

Currently we provide the following functionality:

PyTorch	ONNX	VAD	Number Detector	Language Clf	Languages	Colab
