Fast, expressive, open source TTS with native watermarking
Chatterbox Turbo is a 350M parameter open-source TTS model. It features paralinguistic tags (control laughs, sighs, etc.), zero-shot cloning, and runs 6x faster than real-time. Uniquely includes built-in PerTh watermarking for safety.
This is a really generous release from the Resemble AI team. The "paralinguistic tags" feature is super interesting: being able to simply type [laugh] or [sigh] to control the emotion is a very practical touch for getting natural results.
I also really appreciate that it includes the PerTh watermarking by default. It is rare to see safety features baked directly into an MIT-licensed model like this.
Fast, expressive, and traceable. This model has huge potential in the open source TTS space.
