Piper instructions and settings for the AI Voices mod.

AI Voices - Settings for Piper

AI Voices is really excellent. Full on-the-fly AI voices for characters. The XTTS method is great, but even on a powerful GPU it has a noticeable delay. Piper has no really discernible delay, and is "good enough", in my opinion. These config files and instructions should help people get it working in a polished way.

Installation:

You must download and install AI Voices, with the "Piper" option:

AI Voices: https://www.nexusmods.com/morrowind/mods/59250

You must download the Skyrim mod, Mantella, in order to get its ONNX files:

Mantella: https://www.nexusmods.com/skyrimspecialedition/mods/98631

Place the ONNX and .json files in the directory:

\Morrowind\Data Files\AIVoicesBackend\Piper\voices\

And then place the files in this archive, overwriting anything already in place. It includes two files: a pronunciation file (to correct a few obvious mispronunciations I have encountered so far), and a Piper voicemap, mapping the ONNX files to ALL the races (including Tamriel Data races), as well as mapping voices to a number of named characters. (This process could go on and on and on with customisation, but I think this is a good start.)

Note: The Mantella ONNX files are not even close to being the same voices as found in Morrowind (the male Dunmer in particular is a bit cringeworthy), so this is very different to the voice cloning used by XTTS. However, in my opinion, they are "good enough", and are fast and with no noticeable performance hit.
