Chatterbox Turbo TTS

A faster Chatterbox with sub-200ms latency and inline paralinguistic tags for laughs, coughs, and chuckles.

Chatterbox Turbo is Resemble AI's 350M-parameter speed-focused upgrade to Chatterbox, reaching up to 6x real-time generation with sub-200-millisecond latency. It keeps the original's voice cloning while adding inline paralinguistic tags — you can drop [laugh], [cough], or [chuckle] directly into your text and have the model perform them. Every generation carries Perth watermarking for provenance tracking, a nod to responsible-AI deployment. The combination of low latency and expressive non-speech sounds makes it well suited to real-time voice agents and interactive characters. Like the original Chatterbox, it is MIT-licensed and English-focused.
