A one stop shop to track all open-access/ source TTS models as they come out. Feel free to make a PR for all those that aren't linked here.
This is aimed as a resource to increase awareness for these models and to make it easier for researchers, developers, and enthusiasts to stay informed about the latest advancements in the field.
Note
This repo will only track open source/access codebase TTS models. More motivation for everyone to open-source! 🤗
