Amazon’s line of Echo devices can be set to respond to one of four wake words which include Alexa, Echo, Amazon, and Computer. You used to have to dive into the device settings in the Alexa app to change the wake word but now you can do it on the fly with your voice. Just say “Alexa, change the wake word” and Alexa will ask which of the three alternative wake words you would like to use. Speak your choice and you’re all set. I can see this coming in handy to quickly change the wake word temporarily when watching a movie or TV show that keeps triggering Alexa.
