Adult female. Mild stutter that’s very seasonal, but can get bad sometimes idk. A few eels ago I was suddenly getting these extra long prolongation that made me run out of breath and then right at the end, I’d squeak and my voice would crack. Like as if I’d hit a pitch that was too high. It’s stopped and I can’t replicate it, but I am now having random pitch changes sometimes if I prolong a vowel.
