Fortunately, if someone in your family is named Alexa or if you simply don't like that name, you can change the Wake word that Amazon Echo responds to. You cannot choose your own word, but you can choose from the four words that Amazon supplies: Alexa, Amazon, Computer, or Echo. All Amazon Echo devices come with Alexa as the default wake word. If you want to change this to one of the other three words, open the Alexa app on your mobile device. Choose Settings. If you have more than one device, choose the device. Then tap on Wake Word. Choose the name you want from the dropdown menu and tap Save.
