Google Home knows who’s talking.
When each recognized user speaks Home’s wake words — which are “Hey, Google” and “OK, Google” — Home now switches to that person’s account to give personalized information.
This is a huge deal, a technological marvel and a major leap forward in human-machine interaction.
It’s also a cautionary tale about the downside of overzealous concern about privacy.
How Google Home knows you’re you
Google Home is a virtual assistant appliance similar to the Amazon Echo that runs a version of the Google Assistant. Assistant is also available in Google’s Allo messaging app.
Google Home now supports up to six users for a single device.
