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.
