Amazon's Echo devices are getting a nifty new feature today.

Amazon has revealed Alexa Announcements, a new feature that lets you send a voice message to every Echo in your house at the same time. To make an announcement, just say "Alexa, announce that..." or "Alexa, tell everyone..." or "Alexa, broadcast...".

The feature is supported on the Echo, Echo Plus, Echo Dot, Echo Show, Echo Spot, and Echo Look. It's rolling out to devices in the U.S. and Canada beginning today.

This is different than the two-way intercom feature that Amazon previously rolled out to the Echo and is intended for quick messages that you want everyone to hear. For example, you could announce that dinner is ready or that you'll be leaving for the mall in five minutes, all without having to go from room to room and saying the same thing to all of your family members.
