Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Speech is a critical aspect of the human experience and usually develops in a "seemingly automatic process that continues from birth through adolescence and underlies many related abilities" (e.g., language and reading, see National Academy of Medicine Report on Speech and Language Disorders, 2016). Many individuals with Down Syndrome (Trisomy 21, DS) struggle to communicate and participate more fully in human communication and educational learning experiences because their speech is difficult to understand. The purpose of the proposed project was to measure speech-articulation accuracy and speech intelligibility, and their proposed primary predictors at study entry in 16 children with DS age 4;0 to 17;11). A validated treatment, speech recast intervention (see Yoder, Camarata \& Woynaroski, 2016) was used to drive growth in speech intelligibility as a means of evaluating changes in potential sequelae of change. This study included measures of speech-articulation accuracy, and speech-prosody skills as predictors of speech intelligibility growth in DS.
