Was her deep voice really fake? She has a pronounced larynx, deep jaw and chin, somewhat androgynous face--isn't it possible she simply has/had high-T?
Carreyrou, the author of Bad Blood had an interesting Anecdote from a former employee. Elizabeth and the new employee were meeting for the first time and at the end while expressing her excitement for them joining Theranos, her tone changed to a more high pitched one. Also there is a clip from a Podcast interview where her voice changes before it then goes back to a deeper tone. Though it's not the actual Podcast.
Also her Medicine Professor while at Stanford denies that she has a naturally deep voice.
