Chatterbox

Free open-source TTS that beats ElevenLabs — from Resemble AI.
Chatterbox is Resemble AI's free, open-source production-grade TTS model — the first fully open TTS to beat ElevenLabs in blind listener tests. MIT-licensed, ultra-realistic voices, emotion control, watermarked outputs, and instant voice cloning from a 5-second reference. Runs on a consumer GPU, free for commercial use, and one of the most talked-about AI releases of 2025.
