Why is prosody in speech-language pathology so difficult?

Abstract

An important question for speech-language pathologists is how best to define and characterize atypical prosody, with the eventual aim of designing effective intervention for it. With a view to investigating why prosodic atypicality should be hard to define and what considerations a speech-language pathologist should keep in mind, this paper begins by setting out some established functions of prosody and the forms that convey them, and goes on to review the neurological bases of prosodic disorder and some of the conditions in which prosodic disorder is known to occur. Factors in the perception of prosodic disorder are discussed, including the relationship between prosody and other aspects of communication, to identify the problems of distinguishing between prosody and interacting factors. The relationship between phonological prosodic categories and disordered prosody is considered, i.e., the problems of assigning disordered prosody to these categories for clinicians. Current methods of assessment, transcription and approaches to treatment are briefly considered, and an evaluation is made of how much progress has been made towards answering the initial question.
