Do you use TTS frequently? If yes - please tell us what functionality you expect from it and how configurable its supposed to be?
We obviously won’t be able to voice it all the proper way, but I was considering adding a pre-recorded TTS lines
there's a tutorial for how to download tts lines on youtube. something about how to make a voice like glados from Portal.
There's also AI voices but even that costs money.
If your just looking for easy ways to do voices, I would recommend something more like Banjo Kazooie(I think this method is called Babbles), sounds that tell you this is the character talking, and can change depending on tone, but are not directly saying each word.
