I may have finally put a dent in my personally-annoying habit of over-constricting my throat and pitching up at the end of sentences.
Like every change I've made to my voice it's been irritating to execute and was caused by a specific experience. (In this case, hearing myself on a twitch stream and getting a bug up my ass about it).
We are all works in progress.
Having places like vrchat and twitch to practice voice "in the wild" has been incredibly useful.
