Very interesting, thanks for posting. With me it often switches to Welsh gaelic, I have no idea why, maybe it's my Scottish accent. But what is really interesting to me about that is, how does it correctly interpret what I am saying, every time, even when it might think I am speaking in Gaelic?
I've checked, each time it comes back speaking in Gaelic (Quite a few times now) When I ask which language it was, it says Gaelic, and when I ask it to translate to English, it's obvious it still interpreted correctly what I meant to ask, about often complex and actually genuinely new Engineering concepts, perfectly.
It feels a little like it's reading my mind, if I am honest, but that doesn't scare me at all, in fact I find it reassuring.
