Coqui AI
NewOpen-source AI text-to-speech and voice cloning toolkit for developers building speech applications.
About Coqui AI
Coqui AI is an open-source AI speech technology company that developed TTS (Text-to-Speech), one of the most widely used open-source deep learning TTS toolkits, with state-of-the-art models including XTTS for zero-shot voice cloning from a single audio clip. The XTTS model enables voice cloning across 17 languages from just a few seconds of reference audio, making high-quality multilingual voice synthesis accessible to developers without expensive proprietary APIs. Coqui's models can be run locally on consumer hardware, giving developers full control over privacy, cost, and deployment. While Coqui's commercial streaming service shut down in 2024, the open-source toolkit continues as an active community project with thousands of contributors. Developers building accessibility tools, audiobook production systems, and localization pipelines widely use Coqui TTS for its balance of quality and open accessibility.
