When I have multiple Apple devices in the same room, and I use "Hey Siri", sometimes the wrong device will respond. This isn't always a problem, because a lot of things work the same no matter which device does them. However, sometimes I'll hear something like "You'll need to unlock your iPad first" when I intended the request for my iPhone, which was unlocked recently enough that my request would have gone through fine. Or even more annoying, I'll be in the same room as my dad's HomePod, and "Hey Siri" won't work on any of my devices because they assume I'm talking to the HomePod, even though it's not on my Apple ID. (No Siri, remind me, not my dad.)
Is there any way for me to specify, when I say "Hey Siri", which device I'm talking to, so I can be sure the correct one will respond? I've tried saying e.g. "Hey Siri, iPhone, [...]" but that doesn't seem to work.
