The dock is the same for both models. It has two 3-watt speakers and three far-field microphones so it can hear your commands from across a room. When they're docked, both Tabs function as Alexa-enabled smart displays. You can issue voice commands to Amazon's digital assistant and the dock has a mute button if you don't want Alexa listening.

Alexa offers a wide variety of features from playing music to controlling compatible smart home devices to checking the weather. The display will show extra info after you ask a question. You'll see the forecast after you ask about the weather or a list of steps if you ask for a recipe. When the Tab is in the dock, you'll be able to interact with anything you see on the screen with your voice or with a touch.
