Crate silero_vad_rs

Silero Voice Activity Detection (VAD) - Rust Implementation

This crate provides a Rust implementation of the Silero Voice Activity Detection (VAD) model. It uses the ort crate for efficient ONNX model inference and provides both streaming and batch processing capabilities.

Features

• Voice Activity Detection using the Silero model
• Support for both 8kHz and 16kHz audio
• Streaming VAD with iterator interface and state management
• Batch processing for efficient handling of multiple audio chunks
• GPU acceleration support via ONNX Runtime with CUDA
• Audio file I/O utilities
• Automatic model downloading from Silero repository
• Multiple language support (English, Russian, German, Spanish)
• Comprehensive error handling

Example

use silero_vad::{SileroVAD, VADIterator};
use silero_vad::utils::{read_audio, save_audio};
 
fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Load the model
    let model = SileroVAD::new("path/to/silero_vad.onnx")?;
     
    // Create a VAD iterator
    let mut vad = VADIterator::new(
        model,
        0.5,  // threshold
        16000, // sampling rate
        100,   // min silence duration (ms)
        30,    // speech pad (ms)
    );
 
    // Read audio file
    let audio = read_audio("input.wav", 16000)?;
     
    // Get speech timestamps
    let timestamps = vad.get_speech_timestamps(
        &audio.view(),
        250,    // min speech duration (ms)
        f32::INFINITY, // max speech duration (s)
        100,    // min silence duration (ms)
        30,     // speech pad (ms)
    )?;
 
    // Process timestamps
    for ts in timestamps {
        println!("Speech detected from {:.2}s to {:.2}s", ts.start, ts.end);
    }
 
    Ok(())
}
