There's something that both fascinates me and perplexes me about the online presence of Zheanna "Z" Erose, known for her voice tutorials and (to a lesser extent) music that often experiments with nonstandard tunings. I think she has an interesting "ear" to say the least, and her voice is cis-passing, at least over a microphone, though I'm not sure how much she's consciously working it and how much is just habit now. However, I do worry seeing that the goal for a feminized voice strongly resembles puberphonia. Also, her videos also make me wonder about how a trans woman interested in opera can hypothetically manage it. Erose's technique is mostly centered around speaking with your tongue slightly higher up with a softer phonation and raised larynx, while operatic technique emphasizes "squillo" phonation, dynamics, and a lowered tongue to increase mouth resonance.
Furthermore, her videos do seem more progressive given (as someone who has had a private online session with her) that she did emphasize practice and health, and that she focused more on the resonance qualities of your phonation than on stereotypes or inflections. I think she's somewhere on the spectrum, she's far too cool not to be.
But as someone who tried voice training and could never really internalize it, what are the long term effects? Are you rewiring your brain too? How does it work?
I've kinda accepted my voice as it is.
