Abstract: 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, the book reviews the potential of biological and cognitive models. It examines how the features that make up the speech production and perception systems have been studied by biologists, psychologists, and linguists, and assesses how far biological, behavioural, and linguistic models generate hypotheses that provide insights into the nature of expressive speech.

Keywords: emotive content, tone-of-voice, emotional pitch, speaker attitude, biological models, cognitive models, expressive speech
