What it does

Self-hosts Resemble AI's Chatterbox models behind a web UI and an OpenAI-compatible API: 23 languages, paralinguistic tags like [laugh] and [cough], chunking that handles a whole book, built-in voices plus cloning, and a seed so a voice stays consistent between runs. A Colab is provided if you lack the GPU. Cloning belongs to your own voice or one you have explicit permission for, synthetic output should be labelled as such, and an instance left open on the internet will be used by someone else. MIT.
