Chatterbox is a family of state-of-the-art open-source text-to-speech models by Resemble AI, including multilingual and low-latency Turbo variants with zero-shot voice cloning. It is MIT-licensed and supports emotion exaggeration control and paralinguistic tags like [laugh] and [cough].

Use cases

  • generate speech from text with a cloned voice
  • build a voice agent with low-latency TTS
  • create voiceovers for videos and memes
  • clone a voice across multiple languages
  • add laughs and coughs to synthesized speech
  • run an open-source alternative to ElevenLabs

When to choose

  • you need high-quality open-source TTS with voice cloning under a permissive MIT license
  • you want multilingual speech generation or emotion/exaggeration control
  • you need low-latency speech for AI agents and have a GPU

When to avoid

  • you need a fully managed hosted TTS API without managing model inference
  • you have no GPU and need real-time generation
  • you need languages outside the model's supported coverage
