1. A system for interpretation of natural language inputs to natural language enabled applications comprising:

  • a grammar comprising a set of object-oriented data types and semantic code defining rules about the set of data types, wherein the set of object-oriented data types includes a plurality of classes;

    a source file comprised of computer readable code to access the grammar by instantiating selected data types of the set of object-oriented data types with one or more parameters to produce strongly-typed grammars with associated parameters; and

    a speech recognizer to receive natural language input and to map the natural language input to strongly-typed grammars according to the associated parameters, and wherein the speech recognizer generates a recognition output based on the mapping.
