1. Developing Multimodal Spoken Dialogue Systems : Empirical Studies of Spoken Human–Computer Interaction
Abstract : This thesis presents work done during the last ten years on developing five multimodal spoken dialogue systems, and the empirical user studies that have been conducted with them. The dialogue systems have been multimodal, giving information both verbally with animated talking characters and graphically on maps and in text tables. READ MORE

2. Dialogue processes in computer-mediated communication : a study of letters in the COM system
Abstract : This thesis concerns the basic communicative potentials of a new communications medium: computer-based communication systems. The computer medium has properties which makes it possible to carry out an interactive dialogue, although messages are written and there is a delay between successive contributions. READ MORE

3. Predictive Modeling of Turn-Taking in Spoken Dialogue : Computational Approaches for the Analysis of Turn-Taking in Humans and Spoken Dialogue Systems
Abstract : Turn-taking in spoken dialogue represents a complex cooperative process wherein participants use verbal and non-verbal cues to coordinate who speaks and who listens, to anticipate speaker transitions, and to produce backchannels (e.g., “mhm”, “uh-huh”) at the right places. READ MORE

4. Language Modelling and Error Handling in Spoken Dialogue Systems
Abstract : Language modelling for speech recognition is an area of research currently divided between two main approaches: stochastic and grammar-based approaches are each being differently preferred for their respective strengths and weaknesses. At the same time, dialogue systems researchers are becoming aware of the potential value of handling recognition failures better to improve the user experience. READ MORE

5. Error Handling in Spoken Dialogue Systems : Managing Uncertainty, Grounding and Miscommunication
Abstract : Due to the large variability in the speech signal, the speech recognition process constitutes the major source of errors in most spoken dialogue systems. A spoken dialogue system can never know for certain what the user is saying, it can only make hypotheses. READ MORE
