Pitch range and vowel duration in the speech of children with Williams syndrome
Setter, J. E., Stojanovik, V., Van Ewijk, L. and Moreland, M. L. (2007) Pitch range and vowel duration in the speech of children with Williams syndrome. In: 16th International Congress of Phonetic Sciences, 6-10 August 2007, Germany, pp. 1977-1980.
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 and that vowels tend to be longer in duration than in the speech of the typically developing children. These findings are in line with the impressionistic results reported by Reilly, Klima and Bellugi .
