MeloTTS is one of our recommended TTS services for you to use. It is free, runs locally, and with a low hardware requirement. Currently we have all the default approved Skyrim Voices trained using it. The quality is not as good compared to CHIM XTTS, but it will allow all players to have easy access to a comprehensive TTS service. There is no current way to easily train more voices using the Distro.
It is rather easy to set up. It can be installed using the main installation script or as an optional component folder in the Distro. You can run it on CPU (required usage for AMD users), or GPU (which is faster). After that just select it as the TTS service in the default profile, and speak to any vanilla NPC. They will automatically be allocated with an appropriate voice whenever they are activated.
We do recommend that you use CHIM XTTS if you have the hardware to do so as it is much better quality.
Here is a guide to run it on the cloud (down below in this document): CHIM Manual
The reason we have MeloTTS support is for users who can not run other more powerful TTS services while supporting all Skyrim like voices.
All our current MeloTTS voices are listed at the bottom of this document.
