Understanding Amazon Alexa
What sets Alexa and Echo apart from first-generation Voice assistants is responsiveness, unlike Dragon Naturally Speaking. There’s no activation button to press. Simply say the trigger word: “Alexa,” “Echo,” “Amazon,” or “Computer”, followed by what you want to happen.(Be sure to you’ve set up everything properly and are using the correct command).
Once you get used to the quirks, using Alexa feels much more natural and responsive than speaking to a phone-based voice assistant like Apple’s Siri or 'OK Google'. As a result, you’ll likely find yourself using your phone less frequently when you’re at home or in the office.
