Phonological process identification of misarticulations of mentally retarded children.
Speech samples of 20 mentally retarded children between the ages of 6 yr, 4 mo and 15 yr were analyzed for the purpose of identification of systematic patterns. Liquid deviations and cluster reductions were the most prevalent phonological processes evidenced in their misarticulations. Postvocalic obstruent omissions, deviations of other sonorants (glides and nasals), velar deviations, stridency deletion, stopping, and /theta, sigma/ deviations were demonstrated less frequently. In addition, the children demonstrated pre- and postvocalic devoicing.
