`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 (all see our [STT](https://github.com/snakers4/silero-models)).
Enterprise-grade Speech Products made refreshingly simple (see our [STT](https://github.com/snakers4/silero-models) models).
Currently, there are hardly any high quality / modern / free / public voice activity detectors except for WebRTC Voice Activity Detector ([link](https://github.com/wiseman/py-webrtcvad)).
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 advantages / features:**
**Key features:**
- Modern, portable;
- Small memory footprint;
- Trained on huge spoken corpora and noise / sound libraries;
- Slower than WebRTC, but sufficiently fast for IOT / edge / mobile applications;
- 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 detection for IOT / edge / mobile use cases;
- 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 models:
