# Chatterbox

> Open-source zero-shot text-to-speech and voice cloning model

Chatterbox is an open-source text-to-speech model from Resemble AI designed for expressive, zero-shot voice cloning. It can mimic a target voice from just a few seconds of reference audio while providing control over emotional intensity. It runs faster than real time and includes built-in audio watermarking.
