Abstract

A dialog engine includes methods for integrating multi-modal data capture device inputs with multimodal output capabilities in which a work flow description is extracted from objects in a graphical user interface and a multi-modal user interface is defined. The dialog engine synchronizes the flow of information, in accordance with the work flow description, between input/output devices and an application.
