Answer Wiki. The Amazon Echo and Amazon Echo Dot are stationary devices (they need to be plugged in). The difference between them is that the Amazon Echo has a much better speaker built in, while the Dot is intended for use with an external speaker via line out/Bluetooth. The Dot is much smaller and cheaper so if you want Alexa in multiple locations, it's the best option.
Compared side-by-side with the Echo, the Dot is just as responsive to voice commands: itâs able to hear my voice from across the room, while playing music, or while my two kids are running through the house raising hell. The Dot does have a small built-in speaker, which works great for Alexaâs voice replies and confirmations. It can be used in a pinch to play music, but it certainly isnât room-filling or particularly good sounding. Thatâs where the Dotâs new ability to hook up to a larger speaker comes into play.
