I was just wondering. Do you have to say ok Google or can you just say Google. Cause if In the case I say ok Google my Nexus 6p, pixel C and Google home all start bringing then searching at the same time. Anyway to differentiate the two?
What hallux said is at least true if you have multiple Google Home speakers. Hopefully it'll also integrate phones, tablets, etc, because otherwise we'll end up with exactly that problem.
I'd also like to see custom phrase support, which would help with not setting off your friends' phones, as well as just be a cool feature. Surely Motorola doesn't have some kind of patent/rights to that feature.
He specifically said it will also work among other devices.
Went back & watched that part again

and it sounds like you're right - he said it will respond intelligently across Google Home and Android devices. I do assume those Android devices need to have Google Assistant on them, so older phones may still be "dumb" about responding.
