Automatic Generation of Information State Update Dialogue Systems that Dynamically Create Voice XML as Demonstrated on the iPhone

Helen Hastie, Xingkun Liu and Oliver Lemon

SIGDIAL Workshop on Discourse and Dialogue (SIGDIAL 2009)
Queen Mary University of London, September 11-12, 2009


We demonstrate DUDE (Dialogue and Understanding Development Environment), a prototype development environment that automatically generates dialogue systems from business-user resources and databases. These generated spoken dialogue systems are then deployed on an industry standard Voice XML platform. Specifically, the deployed system works by dynamically generating context-sensitive Voice XML pages. The dialogue move of each page is determined in real time by the dialogue manager, which is an Information State Update engine. Firstly, we will demonstrate the development environment which includes automatic generation of speech recognition grammars for robust interpretation of spontaneous speech, and uses the database to generate lexical entries and grammar rules. A simple graphical interface allows users (i.e. developers) to easily and quickly create and modify spoken dialogue systems without the need of expensive service providers. Secondly, we will demonstrate the deployed system which enables participants to call up and speak to the spoken dialogue system recently created. We will also show a pre-built application running on the iPhone for searching for places such as restaurants, hotels and museums.
