Coqui AI (XTTS)

Coqui AI, specifically its XTTS model, is a powerful open-source tool for multilingual voice cloning. It was developed by the team behind Mozilla's TTS project and is highly regarded in the developer community for its flexibility and performance. XTTS allows for zero-shot cloning in multiple languages, making it a great choice for developers building international applications. Although the company has shifted focus, the open-source models remain a staple for those who want to build their own voice synthesis solutions without relying on proprietary SaaS platforms.
