We were doing speech recognition 20 years ago without any kind of networking. I dictated part of a term paper in 1995. Dragon Dictate I think is what it was called. You could even navigate the word processor menus and UI with it, or say things like “make that bold” and it usually worked! Just a bit less often often than Siri works actually.

Sure it was more of a novelty, and had to be trained on your voice. But that was 20 years ago.
