Modelling of Natural Dialogues in the Context of Speech-based Information and Control Systems
Abstract Current spoken dialogue systems are often
Current spoken dialogue systems are often criticised because they lack natural behaviour. At the same time, the development of natural dialogues is still an expensive and laborious process. Hence, many dialogues are very rigid, as they don’t allow the user to influence the dialogue flow and they use a static phrasing. Our aim is to facilitate the development of more natural speech-based information and control dialogues. Consequently, in this dissertation, a machine-processable model is presented that combines the description of the information demand, communication with the back-end, and the style of the utterance. This dialogue model provides a foundation for generating system questions in different formulations and for realising a close connection between questions, their possible answers and the corresponding language understanding modules. Moreover, the use of an abstract question description and dialogue metadata frees the developer from defining grammars and interpretation modules, while a natural language generation approach that includes politeness and formality variations saves the developer from manually defining prompts in different formulations. A Java-based dialogue engine is implemented that executes the model. It is shown that this XML-based dialogue model provides an easy way to create natural information-seeking dialogues and that it can be run within the implemented dialogue engine.
