Abstract: A novel dialogue design system is provided for creating dialogue applications of the type understood and used by automatic speech recognition systems. The dialogue design system is loaded into a computer having a display and a control keyboard and comprises a novel Dialogue Assistant (DA). The DA is controlled from the keyboard and comprises a navigator screen for defining and connecting compartments of the dialogue application. Each said compartment of a dialogue application is provided with an associated design and editing screen which enables the designer to create, build and edit compartments with associated sounds and variables. Compartments or parts of the dialogue may be played back or used in an actual or simulated environment until the application is proven and ready for use. The dialogue flow may be converted into a machine readable code used by interactive voice response systems with a minimum requirement for manual or machine software implementation.
