All human speech has expression. It is part of the 'humanness' of speech, and is a quality listeners expect to find. Without expression, speech sounds lifeless and artificial. Remove expression, and what's left is the bare bones of the intended message, but none of the feelings which surround the message. The purpose of this book is to present research examining expressive content in speech with a view to simulating expression in computer speech. Human beings communicate expressively with each other in conversation: now in the computer age there is a perceived eed for machines to communicate expressively with humans in dialogue.

Most treatments of speech deal with descriptions of sounds and how they are made. This book goes further: the idea is to develop a framework for a fully explanatory theory of speech production integrating with speech perception. Emphasis is placed on the difference between static models (primarily descriptive) and dynamic models that attempt to show how the basic linguistics and phonetics are related in an actual human speaker/listener.

This book is about the nature of expression in speech. It is a comprehensive exploration of how such expression is produced and understood, and of how the emotional content of spoken words may be analysed, modelled, tested, and synthesized. Listeners can interpret tone-of-voice, assess emotional pitch, and effortlessly detect the finest modulations of speaker attitude; yet these processes present almost intractable difficulties to the researchers seeking to identify and understand them. In seeking to explain the production and perception of emotive content, Mark Tatham and Katherine Morton review the potential of biological and cognitive models. They examine how the features that make up the speech production and perception systems have been studied by biologists, psychologists, and linguists, and assess how far biological, behavioural, and linguistic models generate hypotheses that provide insights into the nature of expressive speech. The authors use recent techniques in speech synthesis and automatic speech recognition as a test bed for models of expression in speech.Acknowledging that such testing presupposes a comprehensive computational model of speech production, they put forward original proposals for its foundations and show how the relevant data structures may be modelled within its framework. This pioneering book will be of central interest to researchers in linguistics and in speech science, pathology, and technology. It will also be valuable for behavioural and cognitive scientists wanting to know more about this vital and elusive aspect of human behaviour.

What roles do the speaker and the listener play in communication processes? Providing an overall system view, this innovative textbook explains how those working in the area think about speech. Emphasising contextual and environmental perspectives, Tatham and Morton lead you through classical and modern phonetics alongside discussion of cognitive and biological aspects of speech. In explaining speech production-for-perception and the relationship between phonology and phonetics, this book shows the possible applications (such as language teaching, clinical practice, and speech technology) and how these are relevant to other disciplines, including sociolinguistics, cognitive neuroscience, psychology and speech acoustics.
