This book gives a short but comprehensive overview of the field of spoken dialogue systems, outlining the issues involved in building and evaluating this type of system and making liberal use of techniques and examples from a wide range of implemented systems. It provides an excellent review of the research, with particularly relevant discussions of error handling and system evaluation, and is ...

One important component of interactive systems is the generation component. While template-based generation is appropriate in many cases (for example, task oriented spoken dialogue systems), interactive question answering systems require a more sophisticated approach. In this paper, we propose and compare two example-based methods for generation of information seeking questions.

We are evolving into a mobile information age where information is expected to be accessed anywhere, anytime, wherever is needed. In this paper, we consider the issues of handling the problems of modality recognizer errors and consistency between multiple modality inputs for a multi-modal dialogue interface in the automobile environment. We describe our work on utterance verification and its ap...

In this paper we will describe ongoing work on an application of Ginzburg's account for short answers in order to improve the nlp component of a spoken dialogue system by using contextual information for disambiguating speech input.

In this paper we present a method for integrating confidence scores into the understanding and dialogue components of a speech understanding system. The understanding component of our system receives an n-best list of recognition hypotheses augmented with word-level confidence scores. The confidence scores are used by the understanding component to hypothesize when words in a recognizer’s n-bes...

The Dialogue-based Reflective Learning System for Historical Text Comprehension consists of two parts: (1) the Diagnosis and (2) the Reflective Tutorial Dialogue. In this paper we present the knowledge representation in the dialogue generator module of the Reflective Tutorial Dialogue System (ReTuDiS), which is based on the Theory of Inquiry Teaching. The dialogue generator uses dialogue strate...
