@wadeal, the point of the voice property of your computer is to specify something you can say to Alexa that makes it easy for her to recognize. So I recommend something simple in your computer's voice field like, "movies"
Alexa/Google Assistant/Cortana don't use the computer's name field, they use the voice field to find your computer.
Click the blue Edit button for your computer on the website to get to that voice trigger field.
