What is the Amazon Echo?
The Amazon Echo is a wireless voice-command device. It is a tall cylindrical speaker (9.25-inches, 23.5cm) which comes complete with a seven-piece microphone array. This device remains in sleep mode and responds to the name “Alexa” whenever it is prompted by voice command. However, this name can be changed by the user. Under development since 2010, the device became widely available on June 23, 2015.
