Hello! (Sorry for the late reply.)
I'm super happy you tried it :) Thank you! ^^
Regarding the voice generator, well, it's not completely free.
Some voices are free, but there's a limit on the number of words each month XD..
I also want to mension that i made a ton of Post-Processing to the voice XD
So if the voice does not sound as good as it seems when you use the generator it's normal..
But still, I hope it will help you in the future ^^
