METHOD AND SYSTEM FOR GENERATING INPUT GRAMMARS FOR MULTI-MODAL DIALOG SYSTEMS

摘要

A method for operating a multi-modal dialog system (104) is provided. The multi-modal dialog system (104) comprises a plurality of modality recognizers (202), a dialog manager (206), and a grammar generator (208). The method interprets a current context of a dialog. A template (216) is generated, based on the current context of the dialog and a task model (218). Further, a current modality capability information (214) is obtained. Finally, a multi-modal grammar (220) is generated based on the template (216) and the current modality capability information (214).
