"Only Caitlyn knows why she decided to Come Out,"
Because she needed to be seen by the public as female and needs that identity reflected back to her.
"One thing I find interesting is that, for all the significant work she had done on her face, she has not pursued any noticeable changes to her voice as far as I can tell."
How do you know she isn't working on it. Voice box surgery raises the base pitch, but doesn't address the resonance, breathing, inflection and prosody of female speech. That is only attained by practice and use. I'm finding that part to be very difficult. I've been practicing for over 2 years. I hardly get misgendered on the phone anymore, but not always. Talking to strangers is much easier than talking to friends, family in the office or to long time clients. I tend to revert back to familiar voice and patterns during those encounters. Talk to many transitioners and transitioned individuals. You'll find that voice is the hardest part of this journey.
