Google Assistant is a little but sure helper.
Google Assistant has many features but it wasn’t able to send a message on Allo or start a video call on Duo.
Google Assistant can now make Duo video calls.
Now with Google Assitant, you can make a video call, you just have to say “video call contact_name” and Assistant will reply, saying it’s making a video call on Duo. (If you don’t have Duo, Hangouts will be triggered.)
Google recently said: “If you use the Google Assistant: You can start a ‘Duo’ video call by saying or typing, “Video call (name).”
The update is rolling out and will be available to every user soon, after the update you can link your Google Duo account using the “Account Sync” option.
The update was released on the latest version of “Duo” for both, Android and iOS.
