Google today enabled the broadcast feature on Google Home devices in English in the U.S., U.K., Australia, and Canada. Now, people with Google Home devices in their house can broadcast announcements or statements from their phone-based Google Assistant to their Home device. For example, parents can say “Ok Google, broadcast I’m on my way home!” to the Assistant on their phone, and it will broadcast to their Google Home for those to hear. People will need to be signed into the same Google Assistant account on all devices for this to work. Google first announced the broadcast feature earlier this year. Broadcast will become available to more languages and countries over time.
