Coqui XTTS
Open-source multilingual TTS with zero-shot voice cloning.
Open-source multilingual TTS with zero-shot voice cloning.
Best for researchers and self-hosters wanting zero-shot multilingual voice cloning under an inspectable license. Pricing: free (CPML license, non-commercial without separate license).
What it is
XTTS is Coqui's flagship cross-lingual zero-shot TTS — a 6-second reference clip is enough to clone a voice and synthesize speech across 17 languages. The library is widely used despite Coqui Inc. shutting down; community forks (idiap/coqui-ai-TTS) keep maintenance going. Consent posture: open weights allow user to clone any voice, so consent enforcement is the operator's responsibility — vendor surface is not a gating layer.
Watch out for: Coqui Public Model License is non-commercial by default — commercial use requires a separate license from Coqui (now via community / forks since the company shut down).
