Changing Amazon Echo devices wake word can be important, especially if your wife or daughter’s name is Alexa. Echo devices have always been able to respond to one of four wake words including Alexa, Echo, Amazon, and Computer.
Typically, you can change Alexa’s wake word by going into Alexa settings and changing it there. Now, you can change the wake word on the fly using Alexa.
Just say “Alexa, change the wake word” and Alexa will ask you which word from the list of four you’d like to use. Your choice response will set the new wake word. It’s that simple. This could be a handy feature to a temporary name change if an Alexa real person happens to be visiting and you don’t want to offend them by ordering your Echo device around, i.e. “Alexa, order Domino’s”.
Unfortunately, you can’t change it to something unique like ‘Fred’. However, that may be a future feature.
