What is Chatterbox Turbo?

Chatterbox Turbo is Resemble AI's fastest open-source TTS model, delivering high-quality English speech with instant voice cloning and expressive paralinguistic controls like [laugh] or [chuckle].

Is Chatterbox Turbo completely free?

Yes, it's 100% free and open-source under the MIT license, with no usage limits or costs for self-hosting.

How fast is generation with Chatterbox Turbo?

It uses a distilled one-step decoder for ultra-low latency inference, often under 200ms on suitable hardware, making it ideal for real-time applications.

What makes it unique compared to other TTS models?

It combines blazing speed, native emotional tags for natural reactions, zero-shot cloning from short audio, and built-in imperceptible watermarking for responsible AI—all in an open-source package.

About This AI

Chatterbox Turbo is an efficient, open-source text-to-speech (TTS) model from Resemble AI, featuring a streamlined 350M parameter architecture for high-quality, low-latency speech generation.

It supports zero-shot voice cloning from just a 10-second (or ~5-second) reference audio clip, native paralinguistic tags like [laugh], [chuckle], [cough] for natural emotional expressions, and one-step audio diffusion for blazing-fast inference.

Every output includes built-in PerTh watermarking for responsible AI use. Optimized for real-time voice agents, narration, and creative applications, it’s English-only and MIT-licensed.
