I've been full time for over a year now, and I have a voice that as far as I can tell passes as cisgender female 100% of the time. However, though my speaking pitch is normal enough, I don't have access to the really high voice, almost a squeal, that women use when they great each other, laugh, show excitement, or scream (obviously). Outside of going under the knife, are there resources out there or exercises that can expand my falsetto and other upper range? I'd really like to have use of a much higher voice.
Thanks!
