Dot connects to the Alexa Voice Service to play music, make calls, send and receive messages, provide information, news, sports scores, weather, and more—instantly.

Echo Dot can hear you from across the room, even while music is playing. When you want to use Echo Dot, just say the wake word “Alexa” and Dot responds instantly.
