ABSTRACT

The purpose of this investigation was to study suprasegmental abilities of three children who had been diagnosed with developmental apraxia of speech/developmental verbal apraxia(DAS/DVA), phonological disorder(PD) and typically developing speech(TD). Three groups of children, who are 5 children with DAS/DVA, 5 children with PD, 5 children with TD were administered suprasegmental tasks. This study is designed to examine the internal juncture and IP-final boundary tone in sentence accent. First, internal juncture is divided into internal open and close juncture. Second, since an accentual phrase(AP) boundary tone in an intonation phrase(IP)-final position is overridden by the IP-final boundary tone, only the IP-final boundary tone(%) was labeled at the end of an IP. This study was used to H%, LH%, HL%, LHL% in IP-final position. Perceptual measures of accuracy of target phrases used 5 rating scales. The principal findings of this study were as follows:First, interval scales of internal juncture produced by children with DAS/DVA and TD was only significant in this study. Second, when IP-final position in sentence accent was examined, DAS/DVA group made significantly more error than the PD group. Overall, the results of this study support the theory that DAS/DVA may have an deviant and delayed phonological representation system and suprasegmental ability in children with DAS/DVA were reflected "linguistic planning" as well as motoric programming" processes. These results suggest that treatment protocols for DAS/DVA should encompass linguistic processing as well as motor programming activities.
