The device consists of a 9.25-inch (23.5 cm) tall cylinder speaker with a seven-piece microphone array. The device responds to the name Alexa; this wake word can be changed by the user to either Amazon or Echo. The device is capable of voice interaction, music playback, making to-do lists, setting alarms, streaming podcasts, playing audiobooks, and providing weather, traffic and other real time information. It can also control several smart devices using itself as a home automation hub. Amazon had been developing Echo inside its Lab126 offices in Silicon Valley and Cambridge, Massachusetts since at least 2010 in confirmed reports.
