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.
Amazon Eco Dot. Take the Echo, slice off the top, and you've got the Echo Dot. The Dot ditches the high-quality built-in speaker to cut down on cost, while still giving you all of Alexa's smarts. A smaller built-in speaker does let you talk to Alexa, but it's not good enough for streaming music.
