What to watch out for

Self-hosting the model takes some technical setup, including a compatible environment and, for fast output, an NVIDIA GPU, so it is not a one-click website tool for everyone. Voice quality and language coverage are not identical across every option, so test the voice pack you plan to use before committing to a long project. As an open-source project, features, model files, and performance can change between releases. Check the current documentation and license terms before you build it into a product or workflow. Behavior may vary across browsers and devices, so test before production use and consult the help docs if errors appear.
