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. 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. If you have more than one Echo or Echo Dot, Alexa responds intelligently from the Echo you're closest to with ESP (Echo Spatial Perception). 

El diseño elegante y compacto hace que Echo Dot sea una adición conveniente a cualquier habitación de la casa. Con su altavoz incorporado, puede colocar Dot en el dormitorio y usarlo como un reloj despertador inteligente que también puede apagar las luces. O use Dot en la cocina para configurar fácilmente temporizadores y comprar decenas de millones de productos de Amazon usando solo su voz.
