A CDE Definition
A family of devices from Amazon.com that combines a wireless speaker, music streamer and virtual assistant in one unit. The Echo speaker connects to a music source via Bluetooth and also streams music from the user's local music collection, Amazon's libraries, iHeartRadio and TuneIn. Introduced in 2015, the Echo is very popular, and several versions followed (see images below).
"Alexa - What's the Capital of Maine?"
Always connected via Wi-Fi, when any of the Echo's seven microphones hears the word "Alexa" from across the room, it "wakes up," emits an audible signal and waits for a question. Because of this wake word, most people call it "Alexa;" however, the wake words "Amazon," "Echo" or "computer" can be used instead.
In 2018, Amazon added intercom capability that lets people broadcast one-way messages to all the Echo devices in the home ("dinner is ready!"). Rather than every Echo in the house playing the same music, a group feature was added that allows devices to play their own tunes.
The Echo App
Available for desktop and mobile devices, the Echo app guides the user through device setup and logs all questions and answers. The app also manages a to-do list, timer, alarms and music sources, and it can be used to ask a question. See Alexa Voice Service, virtual assistant, Bluetooth speaker and Amazon Dash.
