libfvad_swift

libfvad_swift is an open-source Swift package that provides an easy-to-use iOS API for WebRTC's voice activity detection feature (VAD).

forked and ported to SPM from the original implementation here.

Usage Example

import AVFoundation
import libfvad_swift

let detector = fvad_new()

public func runPrediction(on frames: UnsafePointer<Int16>, interval ms: Int) -> Bool {
    let count = ms * _sampleRate / 1000
    switch fvad_process(inst, frames, count) {
    case 0:
        return false // no voice activity
    case 1:
        return true // voice activity detected
    default:
        break
    }
}
