I don’t understand this fragmentation. Even this trigger word should be pronounced world wide in the same way, especially it’s just stripping the first part “hey”. Now, we have to remember how to call it…
dropping the ”hey” has helped me. I just say “Siri” to trigger my iPad Pro when I’m in the same room with the HomePod, and the HomePod requires “hey siri”. Now I can trigger the device I want . 😀
