Abstract

Many studies have pointed to impaired speech intelligibility in young people with Down's syndrome (DS). Some have attributed these problems to delayed phonological development, while others have identified disordered speech patterns, which could be related to a dyspraxic element in their speech. This study uses electropalatography (EPG) to examine the speech of 25 young people with DS, focusing on their production of the obstruent /t/. For the EPG analysis, participants produced the target obstruent in the word 'toe', repeated 10 times. An investigative analysis was carried out. A new descriptive taxonomy of EPG error patterns was developed and these errors were related to perceptually based transcriptions. The measures are discussed in relation to current knowledge of the anatomical and physiological characteristics of DS.
