Amazon Echo is a hands-free speaker controlled with your voice. It features a personal assistant called Alexa, who will perform various tasks for you and control various systems.
There are seven microphones within Echo, all of 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". If you have more than one Echo, or Echo Dot in your home, Alexa will respond from the device closest to you. She is always listening for your command, but you can turn the microphone off with the button on the top of the Echo if you want some privacy.
What can Alexa do?
Alexa will 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, 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 will enable you to customise your Echo device with capabilities to suit your preferences.
There are a number of different skill categories within the Skills section of the app, including Go Places, Stay Informed, Make Your Home Smarter and Be Entertained. 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 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"
