Description

People with the genetic disorder Williams Syndrome often display differences in their speech and language abilities that do not directly correlate with their IQs. Using data acquired and transcribed by the Communications Disorders Program, this work compares patterns of prosody (in part, stress and intonation) in the speech of adolescents with Williams Syndrome and their typically developing peers. The data has been prepared by digitizing the speech waveforms and segmenting the speech into utterances. Using acoustic measurements of pitch, energy, and duration, we performed a statistical analysis of speech that includes factors such as age and gender.
