I know next to nothing about vocal training, and just plan to wing it, but still, if I sing a middle C4, and then try to talk around C4 as around the middle of my voice it just feels and seems way too high honestly. I've heard that talking anywhere from the intervals of a perfect fourth to a perfect fifth above what your voice normally is works as a good way to feminize your voice. Also, when she was starting out in her middle C, it seemed a bit lower than what middle C actually is, so I think as she said, it's best to focus more on inflection, and as I've heard, it's more important to try to get rid of harmonic resonance than it is to raise the pitch. So trying to get rid of that sort of raspy sound, and trying to talk from higher in your head is supposed to help from that. However, I know a lot about music, not vocal feminizing. I'll try to play around with that and see if it really is too high like I feel like right now. Best of luck to you with this method, if you do try it.
