Clinical Phonetics II-1 Pitch range and vowel duration in children with Williams syndrome

Paper File
  This paper reports the pitch range and vowel duration data from a group of children with Williams syndrome (WS) in comparison with a group of typically developing children matched for chronological age (CA) and a group matched for receptive language abilities (LA). It is found that the speech of the WS group has a greater pitch range than the typically developing children, and that that vowel duration in the WS groups tends to be more similar to the LA group. These findings are in line with the impressionistic results reported by Reilly, Klima and Bellugi [16], indicating that children with WS use affective prosody differently to typically developing children.
Clinical Phonetics II-2 Variability in fricative production of young people with Down's syndrome: an EPG analysis

Paper File
  Speech production in Down’s syndrome is highly variable, with particular problems arising from complex articulations such as fricatives. In this paper, EPG analysis is used to study the variation in the production of the fricatives /s/ and /sh/ in 6 young people with Down’s syndrome. The variability of these productions is compared with information from the Robbins and Klee Oral/Speech Motor Control Protocol.

  Recent research has suggested that eliciting diadochokinetic (DDK) rate and accuracy in young children is difficult, with analysis being time-consuming. This paper details a new protocol for assessing DDK in young children or children with intellectual impairment (Down’s syndrome) and a method for calculating accuracy scores automatically. Accuracy scores were calculated from auditory and electropalatographic analyses and found to correlate in some instances. The children with Down’s syndrome presented with similar DDK rates to typically-developing children but reduced accuracy.
