Voice Cloning

Definition

Voice cloning uses AI to create a synthetic replica of a person's voice from a short audio sample, typically 10 seconds to a few minutes. The cloned voice can then speak any text while preserving the original speaker's timbre, accent, and speaking style. It is widely used in dubbing, audiobook production, and accessibility applications.

How It Works

A speaker encoder network extracts a compact voice embedding from the reference audio, capturing the speaker's unique vocal characteristics. This embedding conditions a text-to-speech synthesis model, which generates mel spectrograms that are converted to audio via a neural vocoder. Modern systems like ElevenLabs achieve high fidelity with as little as 10 seconds of reference audio.
