Analysis of the phonological patterns of two physically normal boys, aged 5 and 8 years, with fragile X syndrome, an X-chromosomal abnormality usually connected with severe to moderate mental retardation, found language features similar to those found in other studies of fragile X speech. Some of these language features are: repetition of initial syllables, perseverations, unintelligibility, and in one or the other child, incoherence, comprehension problems, and fast speech tempo. These linguistic features are similar to speech characteristics of normally-intelligent children with developmental apraxis of speech. Systematic vowel errors and errors in place, manner of articulation, and sonority of consonants were also found. (MSE)
