Peer reviewedCrosley, Pamela A.; Dowling, Susann – Journal of Communication Disorders, 1989
The phonological patterns of 22 children with Down's Syndrome, aged 6-12, were tested to assess the relationships among cluster reduction, liquid simplification and sentence length, age, and intelligence quotient. Sentence length was found to be the primary predictor of cluster reduction and liquid simplification in the children's articulatory…

Peer reviewedSamar, Vincent J.; And Others – Journal of Communication Disorders, 1989
The relationships between speech parameters and speech intelligibility of 40 severely to profoundly hearing-impaired adults were studied. Regression analysis revealed that speech intelligibility was predicted by a cognate-pair voice-onset-time difference measure and a measure of the stability of the volume-velocity rise time.
