Two months ago, we did something the industry said was impossible. Our team released Chatterbox—an open-source text-to-speech model that outperformed ElevenLabs with 63.75% user preference in blind evaluations.
The response was overwhelming. Within weeks, Chatterbox exploded to over 1 Million downloads on Hugging Face and above 11,000 GitHub stars. Developers built audiobook generators, game studios integrated it for NPC dialogue, and educators created language learning tools. DigitalOcean called it “significant progress in personalized Voice AI.” The community had spoken: open-source TTS had finally arrived.
But in every GitHub issue, Reddit thread, and Discord conversation, one request dominated: “When will Chatterbox support other languages?”
Today, we answer that call.
