USER INTERFACE AND DYNAMIC GRAMMAR IN A MULTI-MODAL SYNCHRONIZATION ARCHITECTURE

摘要

A first-modality gateway (165) and a second-modality gateway (185) are synchronized, with both gateways interfacing between a user and a server system. Various approaches are described for structuring a grammar of a voice recognition by limiting the amount of the grammar that is searched, thus minimizing the incidence of misrecognition. Communicating with a user may include presenting the user a first set of options and a second set of options, wherein the second set of options is limited based on the user's selection from the first set of options. A graphical user interface (2410) 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 (2420, 2430, 2440) may be individually activated, simultaneously with their respective categories.
