Fire TV cube owners can now use their media streaming device to broadcast announcements throughout the house, much like an intercom. Amazon claims to launch a feature called "Alexa Announcements," which allows customers to talk to Alexa on the Fire TV cube and then share their message with all other Alexa-enabled devices in their household.
For example, you could announce that "the movie is starting," or "Alexa, tell everyone that dinner is ready" and that the message will be sent to your Echo devices or other compatible Alexa-enabled devices are registered in your Amazon account.  If you want to air your program, either say "Alexa, cancel …", "Alexa tell everyone …" or "Alexa Broadcast …", Amazon notes.
In addition, you can send messages yourself The Fire TV Cube also supports announcements sent by selected smart home devices, including those that ring the doorbell or detect motion, starting this month.
In this case, Alexa will recognize things like "motion at the front door" or "someone is at the front door" and you can answer by saying "Alexa, show me the front door" to your camera feed on your TV display.
You can choose which smart home device to customize announcements that you want to see through the new Alexa announcements section in the Alexa app.
Amazon did not say if or when the feature comes to other Fire TV sets.

It supports people with limited dexterity in hands and fingers by giving them the ability to navigate with their voice instead of pressing the keys.
