Your comment reminded me of an interesting video I saw a while back. The video is a talk [0] by a programmer explaining and demonstrating how he developed and used a voice recognition system to program in emacs, after a significant RSI injury.

The commands and syntax he uses to interact with the system might be a decent approximation of the custom English syntax you suggest.
