To that end, Google is now rolling out a Broadcast feature that quite literally lets you broadcast your voice through an Assistant-enabled phone or smart speaker. All one needs to do is say "Ok Google, broadcast" followed by the message, which will then broadcast on Assistant-enabled devices like Google Home. Just say "Ok Google, broadcast it's dinner time" and a dinner bell will ring on all your Google Homes. All you need to do is say, "Ok Google, broadcast I'm on my way home!" But with Assistant now able to identify songs, all Android users will be able to ask Assistant to identify songs on demand.
