Need confirmation from someone with an XB1 if this will work.
Step 1: Text him and find out if he's playing XBox One Step 2: Send him a video of something that I know that he'll watch immediately "New in-game footage of Halo 5" or something like that Step 3: About 20-30 seconds into the video (before he realizes it's an old trailer), the audio cuts to me saying "XBox, Off" or "XBox, search for [insert something disgusting]"
I know that this will work with PS4, assuming someone says the correct phrases, times it well, and speaks clearly enough. Just not sure if XBox needs an extra confirmation to turn off, or if it won't respond to my voice or something.
