Alexa is the voice-controlled Amazon assistant that turns words into actions. If you’re seeking the best Alexa smart speaker for answering queries, playing music from a variety of services, and controlling most smart-home devices (without spending too much), the Amazon Echo (4th Gen) is the one to get. New to the latest version is a Zigbee wireless chip, which allows the Echo to act as a hub for some smart-home devices. The latest Echo sports a new orb design and got a slight audio boost over its predecessor, but it costs the same as previous models (and goes on sale all the time).
MARK ME AS AN BRAINLIST ANSWER
Answer:
Amazon Echo, often shortened to Echo, is an American brand of smart speakers developed by Amazon. Echo devices connect to the voice-controlled intelligent personal assistant service Alexa, which will respond when a user says "Alexa". Users may change this wake word to "Amazon", "Echo", "Computer", as well as some other options.[1][2] The features of the device include voice interaction, music playback, making to-do lists, setting alarms, streaming podcasts, and playing audiobooks, in addition to providing weather, traffic and other real-time information. It can also control several smart devices, acting as a home automation hub.
