Coqui AI NEW
Open-source text-to-speech — train and deploy custom AI voices in any language
Coqui is an open-source text-to-speech platform that lets you train custom AI voice models in any language with as little as 3 minutes of audio data. The TTS library supports state-of-the-art models including XTTS for voice cloning with cross-language capability. A community-driven alternative to proprietary TTS services for developers building voice applications.
💬 User Experience Review
Coqui democratizes voice AI in a way proprietary services cannot. Training a custom voice with 3 minutes of my audio and having it speak naturally in languages I do not know feels like magic. The setup requires technical skill, but for developers building voice products, the control and cost savings versus API-based services are substantial.
