Book Synopsis Usability of Speech Dialog Systems by : Thomas Hempel

Download or read book Usability of Speech Dialog Systems written by Thomas Hempel. This book was released on 2008-04-04. Available in PDF, EPUB and Kindle. Book excerpt: Before designing a speech application system, three key questions have to be answered: who will use it, why and how often? This book focuses on these high-level questions and gives a criteria of when and how to design speech systems. After an introduction, the state-of-the-art in modern voice user interfaces is displayed. The book goes on to evolve criteria for designing and evaluating successful voice user interfaces. Trends in this fast growing area are also presented.

Book Synopsis Practical Spoken Dialog Systems by : Deborah Dahl

Download or read book Practical Spoken Dialog Systems written by Deborah Dahl. This book was released on 2005-02-14. Available in PDF, EPUB and Kindle. Book excerpt: For professional speech researchers, there is a rich technical literature covering many years of primary research in speech. However, this literature is not necessarily applicable to the needs of business people, application developers, and students who are interested in learning about the practical uses of speech technology. On the other hand, while existing introductory resources cover the basic mechanics of development of application development as well as aspects of the voice user interface, they don’t go far enough in dealing with the details that have to be taken into account to make spoken dialog systems successful in practice. What’s missing is information in between the in-depth technical literature and the more introductory development resources. The goal of this book is to provide information for anyone who wants to take the next step beyond the basics of current speech applications but isn’t yet ready to dive into the technical literature. It is hoped that this book will help project managers, application developers, and students gain a fuller and more complete understanding of spoken dialog technology and the practical aspects of developing and deploying spoken dialog applications.

Book Synopsis Spoken Dialogue Systems by : Kristiina Jokinen

Download or read book Spoken Dialogue Systems written by Kristiina Jokinen. This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: Considerable progress has been made in recent years in the development of dialogue systems that support robust and efficient human-machine interaction using spoken language. Spoken dialogue technology allows various interactive applications to be built and used for practical purposes, and research focuses on issues that aim to increase the system's communicative competence by including aspects of error correction, cooperation, multimodality, and adaptation in context. This book gives a comprehensive view of state-of-the-art techniques that are used to build spoken dialogue systems. It provides an overview of the basic issues such as system architectures, various dialogue management methods, system evaluation, and also surveys advanced topics concerning extensions of the basic model to more conversational setups. The goal of the book is to provide an introduction to the methods, problems, and solutions that are used in dialogue system development and evaluation. It presents dialogue modelling and system development issues relevant in both academic and industrial environments and also discusses requirements and challenges for advanced interaction management and future research.

Book Synopsis Estimating Spoken Dialog System Quality with User Models by : Klaus-Peter Engelbrecht

Download or read book Estimating Spoken Dialog System Quality with User Models written by Klaus-Peter Engelbrecht. This book was released on 2012-08-04. Available in PDF, EPUB and Kindle. Book excerpt: Spoken dialog systems have the potential to offer highly intuitive user interfaces, as they allow systems to be controlled using natural language. However, the complexity inherent in natural language dialogs means that careful testing of the system must be carried out from the very beginning of the design process. This book examines how user models can be used to support such early evaluations in two ways: by running simulations of dialogs, and by estimating the quality judgments of users. First, a design environment supporting the creation of dialog flows, the simulation of dialogs, and the analysis of the simulated data is proposed. How the quality of user simulations may be quantified with respect to their suitability for both formative and summative evaluation is then discussed. The remainder of the book is dedicated to the problem of predicting quality judgments of users based on interaction data. New modeling approaches are presented, which process the dialogs as sequences, and which allow knowledge about the judgment behavior of users to be incorporated into predictions. All proposed methods are validated with example evaluation studies.

Book Synopsis Simulation-Based Usability Evaluation of Spoken and Multimodal Dialogue Systems by : Stefan Hillmann

Download or read book Simulation-Based Usability Evaluation of Spoken and Multimodal Dialogue Systems written by Stefan Hillmann. This book was released on 2017-11-23. Available in PDF, EPUB and Kindle. Book excerpt: This book describes an extension of the user behaviour simulation (UBS) of an existing tool for automatic usability evaluation (AUE). This extension is based upon a user study with a smart home system. It uses technical-sociological methods for the execution of the study and the analysis of the collected data. A comparison of the resulting UBS with former UBSs, as well as the empirical data, shows that the new simulation approach outperforms the former simulation. The improvement affects the prediction of dialogue metrics that are related to dialogue efficiency and dialogue effectiveness. Furthermore, the book describes a parameter-based data model, as well as a related framework. Both are used to uniformly describe multimodal human-computer interactions and to provide such descriptions for usability evaluations. Finally, the book proposes a new two-stage method for the evaluation of UBSs. The method is based on the computation of a distance measures between two dialogue corpora and the pair-wise comparison of distances among several dialogue corpora.
