This is a great idea submitted by Al Peterson. Al adds these notes:

A consultant at the recent Talkers conference is telling station managers to create an on-air voice drop that says, "Hey Alexa ...(pause) ... play the [morning show podcast]!", complete with the mandatory pause that activates the data assistant.

Alexa is already doing too much for lazy fat-assed Americans and she's fighting back!

Fun to splice into some rotating fake "Hey Alexa!" promos on a rocker. FWIW, the voice came off this website: https://www.naturalreaders.com/online/ -- with a little filtering and speaker distortion provided by a vintage copy of Cool Edit.
