This book reports recent research on mechanisms of normal formulation and control in speaking and in language disorders such as stuttering, aphasia and verbal dyspraxia. The theoretical claim is that such disorders result both from deficits in a component of the language production system and interactions between this component and the system that 'monitors' for errors and undertakes a corrective behaviour. In particular, the book focuses on phonological encoding in speech (the construction of a phonetic plan for utterances), on verbal self-monitoring (checking for correctness and initiating corrective action if necessary), and on interactions between these processes. Bringing together sixteen original chapters by leading international researchers, this volume represents a coherent statement of current thinking in this exciting field. The aim is to show how psycholinguistic models of normal speech processing can be applied to the study of impaired speech production. This book will prove invaluable to any researcher, student or speech therapist looking to bridge the gap between the latest advances in theory and the implications of these advances for language and speech pathology.

This book reports recent research on mechanisms of normal formulation and control in speaking and in language disorders such as stuttering, aphasia, and verbal dyspraxia. The theoretical claim is that such disorders result from (1) deficits in a component of the language production system and (2) interactions between this component and the system that "monitors" for errors and undertakes corrective behavior. More in particular, the book focuses on phonological encoding in speech (the construction of a phonetic plan for the utterance), on verbal self-monitoring (checking for correctness and initiating corrective action if necessary), and on interactions between these processes.
The first part of the book deals with phonological encoding. The architecture of the phonological encoding system is described, with regard to both normal and patholgical (conduction aphasia, stuttering, developmental dyspraxia) production. Both in normal and in pathological speech, there are monitoring processes thatcontrol speech. These control mechanisms for detecting and correcting these errors are discussed.
The second part of the book outlines the architecture of monitoring, both from an empirical and a modelling approach. subsquent chapters deal with language dysfunction, either as a disturbance in monitoring itself or as the result of interactions between monitoring and phonologiclal encoding.
