Alexa follows your voice commands to dim the lights, turn up the thermostat, set a timer, turn on the TV, or create a shopping list (and that’s just the tip of the iceberg!).
Buying an Amazon Echo is the easiest way to get Alexa. To get Alexa’s attention, say the watchword: “Alexa.” You can also set it to “Echo”, “Computer” or “Amazon.”
After waking up, Echo records everything you say and sends it to Alexa Voice Services, where artificial intelligence processes your request and executes it. It’s a lot of work, but Alexa is so fast you don ‘t even notice it.
In addition to basic requests, Alexa also works with a variety of other technologies in your home, your car, and elsewhere, so you can use Alexa for everything from starting a pot of coffee to ordering an Uber.
