Amazon announced the Fire TV Cube on Thursday. It’s basically a Fire TV with a speaker and the Alexa smart assistant built-in. Amazon hasn’t done this before.

The Fire TV Cube connects to your TV and can provide up to 4K UHD content from Amazon Prime services, Hulu, Netflix and other apps. It also serves as an Echo speaker, which means you can do things like call across the room to check the weather, turn on the lights, order things from Amazon or call a friend.

There’s a reason this is cooler than similar streaming boxes on the market, though, including Amazon’s earlier Fire TV gadgets.

Unlike other Echo and Fire TV products, it supports cable TV boxes, giving users the option to change by voice the cable TV channel they’re watching. “Tune to CNBC,” or “tune to channel 834,” you might say. Comcast, DISH and DirecTV are a few of the cable services it will support at launch.

Some cable subscribers might already be used to similar functionality. With Comcast X1, for example, you can speak into your remote to change the cable channel. Now, you’ll be able to control your cable box, your Fire TV and ask Alexa questions.

It’s a unique move for Amazon, which has so far seemed to try to keep users inside the Fire TV app and away from cable TV. This also means Amazon is now catering not only to cord cutters but those who still pay for cable.

The Fire TV Cube launches June 21 for $119.99.

Disclosure: Comcast owns CNBC parent NBCUniversal and is a co-owner of Hulu.
