I've taken more to using Voice Attack for multiple complex commands and triggering them with a joystick button rather than voice. For example, in Elite Dangerous, one button press will get clearance to dock at a station. I currently use a button on my StreamDeck for that. If you're familiar with the game you know that's a several step process.

Though some of the new headsets have better cameras for mixed reality they still probably won't be great for using a keyboard or even a touchscreen like I have below.
