This book deals fundamentally with the quality and usability of communication technology systems. To this end, the necessary terms are first introduced, and the fundamentals of psychophysics and psychometrics are established. Based on this, the cycle of human-oriented system development is presented. The measurement and prediction of quality and usability are then illustrated by practical examples of communication engineering systems. In particular, systems for information transmission (telephony, VoIP, IP-TV), speech dialog systems, and multimodal dialog systems are discussed. Finally, models for estimating quality and usability in the development phase of such systems are presented. The book is primarily aimed at readers with a technical background, for example in computer science, information technology, or electrical engineering. In addition, however, readers from linguistics and communication sciences, acoustics, sociology, human factors, and other fields of knowledge areequally addressed. It does not presuppose any special previous knowledge. This book is a translation of the original German 2nd edition Quality Engineering by Sebastian Möller, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2017. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.

? Dieses Open-Access-essential schafft Orientierung, wenn Künstliche Intelligenz im klinischen Alltag eingesetzt wird. Die Herausforderungen werden anhand zweier Beispiele aus dem Bereich der Nephrologie erläutert, die ethisch und rechtlich reflektiert werden. Ein umfangreicher Empfehlungsteil schließt diesen durchweg interdisziplinär erarbeiteten Band ab.

The quality of a telecommunication voice service is largely inftuenced by the quality of the transmission system. Nevertheless, the analysis, synthesis and prediction of quality should take into account its multidimensional aspects. Quality can be regarded as a point where the perceived characteristics and the desired or expected ones meet. A schematic is presented which classifies different entities which contribute to the quality of a service, taking into account conversational, user as weIl as service related contributions. Starting from this concept, perceptively relevant constituents of speech communication quality are identified. The perceptive factors result from ele­ ments of the transmission configuration. A simulation model is developed and implemented which allows the most relevant parameters of traditional trans­ mission configurations to be manipulated, in real time and for the conversation situation. Inputs into the simulation are instrumentally measurable quality elements commonly used in transmission planning of telephone networks. A reduced set of these quality elements forms a basis for models which aim at predicting mouth-to-ear quality as it would be perceived by a user of the sys­ tem. These models are an important tool for the planner of telecommunication networks, as they allow the expected quality to be estimated in advance, even before the network has been set up. Two well-known models (the SUBMOD and the E-model) are analyzed in more detail, with an emphasis on the psy­ choacoustic and psychophysical backgrounds.

Quality of Telephone-Based Spoken Dialogue Systems is a systematic overview of assessment, evaluation, and prediction methods for the quality of services such as travel and touristic information, phone-directory and messaging, or telephone-banking services. A new taxonomy of quality-of-service is presented which serves as a tool for classifying assessment and evaluation methods, for planning and interpreting evaluation experiments, and for estimating quality. A broad overview of parameters and evaluation methods is given, both on a system-component level and for a fully integrated system. Three experimental investigations illustrate the relationships between system characteristics and perceived quality. The resulting information is needed in all phases of system specification, design, implementation, and operation. Although Quality of Telephone-Based Spoken Dialogue Systems is written from the perspective of an engineer in telecommunications, it is an invaluable source of information for professionals in signal processing, communication acoustics, computational linguistics, speech and language sciences, human factor design and ergonomics
