This book reviews the clinical applications of phonological principles and analytical procedures to the spoken language of people with speech and language pathologies. Exercises at the end of each chapter provide the reader with further experience in the use of procedures discussed. This edition retains the basic structure of the earlier edition, with revisions throughout to take account of new ideas and advances. New sections have been added to chapters three to seven reviewing clinical assessment procedures, based on the analytical frameworks described in each of these chapters. The final chapter has been comprehensively revised to reflect the shift in orientation towards the cognitive aspects of phonetics and phonology.
