The topic for this Perspectives issue is the prosody of acquired neurogenic communication disorders. Prosody is that elusive dimension of speech that is superimposed on other linguistic units—such as words, phrases, and sentences—and that affects several speech segments across some period of time. It includes variations in stress, intonation, rate, and rhythm; is perceived on the basis of relative pitch, loudness, and duration; and can be quantified acoustically through a combination of fundamental frequency, intensity, and duration measures.
Prosodic variations are powerful. They can alter fundamentally the meaning of the words, phrases, and discourse we produce, and sometimes they send such important messages about our emotions or attitudes that the words themselves become unimportant. Neurogenic communication disorders often have profound effects on prosodic speech properties. The nature of the deficit provides valuable information about differential diagnosis and lesion localization and their consequences demand effective treatment. Each of the five authors who contributed to this issue has addressed prosodic features characteristic of a distinctive disorder. They explain salient prosodic markers for that disorder and discuss their relevance for clinical practice.
