Amazon Echo is one of a range of hands-free speakers and devices that can be controlled with your voice. The voice-controlled Amazon "personal assistant" on these devices is called Alexa, who will perform various tasks for you and control various systems.
In this feature we'll explain what Echo is fully and answer other questions such as "What can Alexa do?".
As well as being available on Echo devices, Alexa is now becoming available on a lot of third-party devices plus the Alexa app on Android phones (the app is also available for iOS so you can configure Alexa-enabled devices, but without the voice-controlled assistant).
There are microphones within Echo devices, which feature enhanced noise cancellation and far-field voice recognition, meaning you can ask Alexa a question from any direction, even when playing music, and she should still hear you.
Amazon Echo's personal assistant will respond to the wake word "Alexa". The Amazon Echo range includes the standard Echo (it's the second-generation device), Echo Plus, Echo Show, Echo Dot and Echo Spot. There's also an Echo Tap in the US.
If you have more than one Echo, Echo Dot, Echo Show, Echo or another Alexa-enabled device in your home like the Sonos One, Alexa will respond from the device closest to you.
She is always listening for your command, but it is possible to turn the microphone off on Echo devices and devices like the Sonos One speaker if you want some privacy.
What can Alexa do?
Alexa is able to play music, provide information, deliver news and sports scores, tell you the weather, control your smarthome and even allow Prime members to order products they've ordered before.
She updates through the cloud automatically and learns all the time. The more you use Echo devices, the more Alexa adapts to your speech patterns, vocabulary and personal preferences.
What can you ask Alexa?
There are plenty of things you can ask Alexa to do. A feature called Skills in the Alexa app enables you to customise your Echo device with capabilities to suit your preferences.
There are several skill categories within the Skills section of the app, including Connected Car, Food & Drink, Travel & Transportation, Music & Audio, Smart Home, and plenty more. To get started, you just have to tap Enable Skill when you've found one that is suited to you.
Some will require you to link to an existing account or separate subscription to use. For example, to use Uber with Alexa, you'll need to have signed into your Uber account within the Skills section of the Alexa app. Here are just a few examples of what you can ask Alexa to do.
"Alexa, wake me up at 7 in the morning"
"Alexa, ask Skyscanner for a flight to New York"
