I was fiddling around in SynthV2 with GUMI, and came across the gender parameter:
I was like, "Oh, yeah! I forgot you could mess around with that." I wondered what GUMI would sound like with gender cranked up all the way. Obviously, I was kind of expecting the tone to be deepened when I put it all the way at 1.000, but I was curious about lowering it down to -1.000. Would it just make her sound more feminine? How would that work? I had to know. So:
I set it up. Then, I set up a voiceline I could test it with and pressed play.
And what followed was the most harrowing 10 seconds of my life. After that, my mind was filled with nothing but fulfilling what had to be done, which is what produced the 8 second sound clip you see above. The immense regret I felt afterward was nothing short of coming down from committing some kind of crime against various gods. Enjoy!
