ABSTRACT:
The present invention includes a context-free grammar (CFG) engine which communicates through an exposed interface with a speech recognition engine. The context-free grammar engine, in one illustrative embodiment, handles loading and unloading of grammars, as well as maintaining a desired activation state of the grammars which are loaded. Further, the CFG engine represents all loaded grammars, and their corresponding activation states, as a single grammar to the speech recognition engine.
