Google Home users in the U.K. are now able to make calls months after it was first announced in Google IO back in 2017. To get started, simply say “Ok Google” or “Hey Google” followed by the person that you would like to call.
For this to work you don’t even need your phone as the speaker will use Google Contacts as an address book and place the call over Wi-Fi. Google Home speakers can recognise up to six different users in the UK.
When you call someone for the first time, your Home speaker will show up as an unknown or private number but you can set up caller ID so your number appears for every subsequent call.
