Yep, and that's why it's absolutely ABSURD that I managed to do it completely blind and without even looking at the instructions! Holy cow I really do think I'm a genius, especially with how stupidly easily I can manipulate the AI girl to do what I want. Haha
I'll give you detailed instructions for how to do it then. First you need to make an account and manage to log in. Then go to home, select speech services, then select create (it has a small blue plus next to it, it's a smallish button). Then just fill the "name" bar with whatever, and go select the free f0 pricing tier for the "pricing tier" bar.
Good luck wondering how I managed to figure all this out without literally any help, it's a total mystery to even me. But yeah just follow my instructions and it's real quick after you have an account and are logged in.
