content: My guess is that it's not. I don't know too much about it, but I'm guessing that it learns by correction. If it sees Caitlyn Jenner instead of Bruce Jenner enough times, and given the fuss that was made and the amount of times that name was mentioned, it would have, then I'd assume it would note that.  Bear in mind this is just speculation. It's just what seems more logical to me to be happening than for this to be altered for one person.
