Variability in fricative production of young people with Down's syndrome : an EPG analysis

By Claire Timmins, William J Hardcastle, Sara Wood, Joanne McCann and Jennifer Wishart


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
