Amazon marketed this as a way to replace Alexa’s voice with Samuel L Jackson’s. What you get is a skill for Alexa that makes you sound like someone who is mad at someone in the same room. Example, “Alexa, Ask Sam what the weather is like”. Then you get a Samuel L Jackson Response, He doesn’t answer everything, and otherwise you’re stuck with Alexa.
