Amazon Echo Dot is a hands-free, voice-controlled device with a small built-in speaker—it can also connect to your speakers or headphones over Bluetooth or through a 3.5 mm audio cable to deliver stereo sound to the speakers you choose. Echo Dot connects to the Alexa Voice Service to play music, make calls, send and receive messages, provide information, news, sports scores, weather and more. All you have to do is ask.
Echo Dot can hear you from across the room—even in noisy environments or while playing music. When you want to use Echo Dot, just say the wake word “Alexa” and Echo Dot responds. If you have more than one Echo or Echo Dot, Alexa responds intelligently from the device you’re closest to with ESP (Echo Spatial Perception).
