1. Method for representing a target software application program to a voice recognition navigator program on a computer system, said method comprising:

  • analyzing an application program to determine a plurality of application states, each of said application states being comprised of a plurality of window objects;

    organizing each of said application states in the form of a sub-context tree, each of said sub-context trees being comprised of a plurality of sub-context objects defining the hierarchical relationship among each of said sub-context objects;

    determining a set of attributes associated with each of said window objects, and assigning a matching set of attributes to each of the sub-context objects;

    storing the sub-context trees in a memory device of said computer system as a context data file;

    executing said voice recognition navigator program on said computer system concurrently with said target application program;

    analyzing said target application with said voice navigator program to determine a current target application state of said target application program and matching said current target application state to a corresponding sub-context tree by comparing a window object from the current target application state to at least one of said sub-context objects stored as part of said context data file;

    defining an active vocabulary set for the current target application state by retrieving from said context data file at least one sub-context object vocabulary set.
