Amazon today added Alexa features to the Fire TV Cube. You should now be able to call, send voice messages and Drop In on other Alexa devices straight from your Fire TV Cube. These features are already available on Amazon smart speakers and displays.
The Fire TV Cube is a $120 media player with a built-in Alexa speaker. Use voice commands just like you would with a regular
speaker or smart display using the wake word "Alexa." Ask Alexa via the Fire TV Cube to turn on your TV, play your favorite Netflix show and more -- there's no need to enlist a remote like you would with a Fire TV Stick (although you can also use the Fire TV Cube remote, if you want).
