This comprehensive book has become an internationally recognized standard reference on measurement of physiological and acoustical aspects of speech and voice. It is specifically written for those without a technical background and includes a wide assortment of observational and measurement techniques. It offers explanations of their theoretical and technical foundations, comparisons of instrumental techniques, and extensive graphics to inform the clinician's choice of appropriate measurement tools. Just as important, this book includes extensive summaries of test results, allowing a particular patient's performance to be assessed in a valid context.TEXTBOOK
