Google Home can now recognize individual users by the sound of their voice

The setup process involves adding additional users through the Home app, who then train the device to recognize them by repeating a few key phrases. Google uses a neural network that's actually located on the device itself to differentiate the distinct voices in the household. The system will still respond to requests from random people, like a guest in your home, but it also means that your Home device should only read your more personal information--like what's on your schedule for the day--to you.
