I guess the fact that you have a delay associated with the recognition of commands not loaded into the recognizers current vocabulary is an artifact associated with the design of the recognizer which was probably tuned towards continuous speech. In other words your dynamic grammars idea was a way to work around a limitation of the speech recognizer you were using. Part of the benefit of designing a language specifically for speech based coding is that the design of the associated recognizert could be tuned to that language. Compared to a brute force translated version of the keyboard input based language developer workflow, a speicifcally designed language would likely have a far narrower vocabulary. This would make it possible to tune a recognizer for better recognition accuracy and speed.
