Wake command

You can wake up Alexa by using the wake command “Computer” as in Star Trek. Go to the Alexa app on your phone. Right-swipe to open a panel with settings choices. Pick your device and scroll down to wake commands. You have a limited choice of four words, including computer. There is a movement to make that command a common voice interface among all devices. Are you listening, Siri, Cortana and Google? — KK
