Teardown: Amazon Echo

31 May 2017
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

Amazon Echo is a hands-free speaker users can control with their voice. It can be connected to Alexa Voice Service to play music and provide information like sports scores, news, and weather updates. Echo has seven microphones and beam forming technology so it can hear you from across the room. Is also a tuned speaker that can fill a room with 360° immersive sound. When you want to use Echo, just say the wake word “Alexa” and Echo 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).
