Cobra Voice Activity Detection Engine

Made in Vancouver, Canada by Picovoice

Cobra is a highly accurate and lightweight voice activity detection (VAD) engine.

Compatibility

• Rust 1.54+
• Runs on Linux (x8664), macOS (x8664), Windows (x86_64), Raspberry Pi, NVIDIA Jetson (Nano), and BeagleBone

Installation

First you will need Rust and Cargo installed on your system.

To add the cobra library into your app, add pv_cobra to your apps Cargo.toml manifest: toml [dependencies] pv_cobra = "*"

Usage

Create an instance of the engine:

```rust use cobra::Cobra;

let accesskey = "..."; // AccessKey provided by Picovoice Console (https://picovoice.ai/console/) let cobra = Cobra::new(accesskey); `` whereaccess_keyis an AccessKey which should be obtained from [Picovoice Console](https://picovoice.ai/console/).cobra` is an instance of Cobra that detects voice activities.

```rust fn nextaudioframe() -> Vec { // get audio frame }

let threshold = ... // Detection threshold within [0, 1]

loop { if let Ok(voiceprobability) = cobra.process(&nextaudioframe()) { if voiceprobability >= threshold { // Detection event! } } } ```
