Voice broadcasting

Voice broadcasting is like when you play a message for lots of people at the same time, like a big phone call. Imagine you have a big party and want to tell everyone the same thing at the same time. You could call each person one by one and tell them the message, or you could make one phone call and have the message play for all of them at once. That's like what voice broadcasting does. It can send one message to lots of people all at the same time. It's like magic!
