Introduction to Silero-VAD

The Silero-VAD project is designed to enhance the quality of speech detection through a customizable Voice Activity Detection (VAD) model. Developed with the support of the Innovation Support Fund as part of the federal project on Artificial Intelligence, this model is tailored for use with custom datasets, making it a powerful tool for developers and researchers in the field of speech processing.

Main Features of Silero-VAD

• Customizable Training: Fine-tune the model on your specific datasets for optimal performance.
• High Accuracy: Achieve superior speech detection with a focus on ROC-AUC metrics.
• Flexible Configuration: Utilize a comprehensive configuration file to set training parameters.
• Support for Multiple Audio Formats: Work with various audio formats including .wav and .opus.
• Open Source: Contribute to and benefit from a community-driven project under the MIT License.

Technical Architecture and Implementation

The Silero-VAD model is built using PyTorch and relies on several key dependencies:

• torchaudio>=0.12.0
• omegaconf>=2.3.0
• sklearn>=1.2.0
• torch>=1.12.0
• pandas>=2.2.2
• tqdm

This architecture allows for efficient processing and tuning of audio data, ensuring that the model can adapt to various speech patterns and environments.

Setting Up Silero-VAD

To get started with Silero-VAD, follow these steps:

1. Clone the repository from GitHub.
2. Install the required dependencies using pip:

pip install -r requirements.txt
