Folks have created Dragon-based voiced-sound vocabulary for editor control. Voice strain is an issue, but you can load share with typing.

You can do Google voice recognition in browser/WebVR, but it's better at sentences than brief commands.

Another component, largely unexplored, is hand controller motion. The Vive's are highly sensitive in position and angle. Millimeterish. So imagine swype text (phone keyboard continuous sliding) with 6 DOF. Plus the touchpad (the buttons aren't something you'd want to use all the time). Keyboard+pad is mature tech. But wands-with-pads look potentially competitive, and (not yet available) hand-mounted finger tracking added to keyboard+pad might make for a smooth transition. Plus voice. The space of steep-learning-curve input UIs for professionals looks intriguing.
