The voice-controlled home assistant Google Home now features voice recognition to distinguish between several user accounts.
The biometric solution means it is possible to train the device to recognise and identify six different voices.
Because users can connect different Google accounts on the same Home, they can get a more personalised service.
Wired reports that the company is using its artificial intelligence neural networks – that work in search and Google Translate – to identify different people.
"When you connect your account to a Google Home, we ask you to say the phrases "Ok Google" and "Hey Google" two times each," the company says in a blog post about the update. "Those phrases are then analysed by a neural network, which can detect certain characteristics of a person's voice".
As The Verge notes, Google Home isn't able to separate between a user's personal and work accounts. This means only one account per user can be used at present.
The feature is arriving today in the US and coming to the UK "in the coming months," said the company.
