Importing Python scripts / TTS?

[Logically Anime]

So a little background info I am creating a mod of a game that brings voices to the characters. However, there is one part of the game where the character reads the player's Steam username or computer username. I was thinking for that, I would have a TTS engine with the voice actor as the voice using this project: https://github.com/OpenSpeaks/Lekatha
However, I am new to Python and Ren'Py, and don't know how I would implement the script to the game. Any help would be appreciated!

DDLC is corrupting a lot of people.
If you're new to python implement external modules and learn how to make any class from them is out of your reach and for regular users to explain.
I suggest you to ask a coder to join the project (hopefully free) cause a task like require a strong coding background.

I do have some background in python but not much, I am able to add the voices themselves to the game, all I don't really know how to do is the tts part.
