We came across this video that shows using Windows Speech Recognition Macros to control Maya.
This turned out to be a great way to use Maya and our UI in Virtual Reality.

Please check out this video:

1. Download and install Windows Speech Recognition Macros:

2. Open Maya and create a new hotkey with the hotkey editor (Window menu, Settings-Preferences-Hotkey Editor)

3. In the Categories frame in the Hotkey Editor (it is on the left) Scroll down and click -User-.

4. Click the -New- button. Give your hotkey a Name (and a Description if you like). Then under language, type in a Mel (or Python) command ie. -HypershadeWindow;- without the quotes. Then click the -Accept- button.

5. Give it a hotkey (make sure your new Command Name is selected in the Commands frame of the HotKey Editor). Under -Assign New Hotkey-, type in a key in the -Key:- field. Anything on your keyboard will do. ie the letter q. In the -Modifier- fields, make sure to tick Ctrl and Alt (as most shortcut keys in Maya do not have anything assigned to a Ctrl-Alt combination. (You can click the Query button to see if it is already assigned, but if you use a Ctrl-Alt combination, it probably isn’t). Then when you are happy with your hotkey, click the -Assign- button.

6. In the taskbar (bottom right), double-click the, -Windows Speech Recognition Macros- icon.

7. In the New Speech Macro window, select, -Send keystrokes-. In the first field, enter a phrase you would like to say to envoke the keystroke via speech recognition ie. -hypershade-. In the second field, enter your Hotkey in the following manner: {{CTRL}}{{ALT}}q (or whatever your hotkey happens to be) and click the -Next- button. At some point it will ask you to Sign Speech Macros, I recommend you do so. So really, all you have to remember is that a ctrl click or an alt click needs to have double curly brackets before and after it. (They show you that though so you won’t forget.)

8. Close the Hotkey Editor window in Maya, ensure you have speech recognition turned on and test it by saying the word you typed. ie. -Hypershade-
