Abstract
A graphical user interface may include a form with a plurality of fields, each field associated with a predetermined category. Each category may have its own, independent, discrete grammar associated therewith, and the independent grammars may be individually activated, simultaneously with their respective categories. In this way, a voice-recognition system that is inputting spoken data for each of the fields may have a restricted grammar to search when attempting to match a particular voice input with an entry for a particular field in the form. Moreover, a global grammar that is active with any one of the independent grammars may be used to move between the fields or perform other high-level functionality not associated with any one of the independent grammars.
