Abstract
Some of the most common forms of speech impairment are summarised here, in terms of their main distinctive acoustic and temporal characteristics (rhythm, intonation, etc.). Where they offer significant advantages, we also mention some non-acoustic methods for assessment and diagnosis. The speech disorders considered in this book are neurological in origin: primarily dysphonia, dysprosody, dysarthria and apraxia of speech, but we also mention some considerations relevant to the diagnosis of stuttering, Parkinson’s disease and even schizophrenia. It is suggested that the tasks of assessing severity of a condition, and of differential diagnosis, need not use the same acoustic features, and indeed there may be significant advantages in using complementary features and procedures for the two tasks.
