Contemporary speech synthesis is perceived as inadequate for general adoption for user interaction, largely because it rests on an inadequate model of human speech production and perception. This book reviews the underlying model, brings out areas of inadequacy and suggests how improvements might be made. It is argued that a greater understanding of the fine detail of speech will enable new research and application initiatives. The authors draw on their extensive experience in both theoretical and applied research to bring forward proposals for producing more natural sounding synthetic speech.

• Provides an overview of the current work in speech synthesis, including a critical review of markup systems (including XML and SSML) embedded in interactive applications.
• Argues that naturalness in synthesis will benefit from enhancements to underlying models of prosody which more accurately account for the properties of human speech, yet can also be productively transferred to speech synthesis.
• Emphasises the importance of an explicit and extensible architecture as the basis for future developments, stressing particularly the importance of close modelling of expressive and emotive content – key features of naturalness.
• Focuses on the dynamic nature of prosody, as opposed to the more usual static treatment, especially as an adaptive model compliant with pragmatic and environmental constraints.

During the past decade, the design and development of current and emerging wireless systems have motivated many important advances in multiuser detection. This book fills an important need by providing a comprehensive overview of crucial recent developments that have occurred in this active research area. Each chapter is contributed by noted experts and is meant to serve as a self-contained treatment of the topic.

Liquid crystal technology is a subject of many advanced areas of science and engineering. It is commonly associated with liquid crystal displays applied in calculators, watches, mobile phones, digital cameras, monitors etc. But nowadays liquid crystals find more and more use in photonics, telecommunications, medicine and other fields. Accordingly, first half of this book is dedicated to fundamental properties of liquid crystals, while Chapters 7-12 give a picture of recent trends in the sphere of liquid crystal displays and light modulators.
