Seeing how other smart assistants have a one-word wake command, why doesn't Apple simplify it to just "Siri"? I suppose the "hey" doesn't bother me as much but, as a Spanish-speaking person, I loathe saying "Oye Siri" because that's a word we almost never use. The English equivalent to that would be having to say "Yo Siri". I'm sure this would annoy quite a few English-speaking people. So, why do we need another word before Siri?
