The speech productions of 19 hard of hearing children between 5 and 12 years of age were examined for errors related to phonological process categories. For comparison, the subjects were divided into groups of 9 with Profound and 10 with Moderate to Severe hearing losses. There was a significant relationship between hearing loss and phonological errors. Seven phonological processes were evident in at least 33% of obligatory contexts. Prevalent processes included final consonant deletion and cluster reduction. The most prevalent deficiencies included /r/ and /1/ phonemes. Subjects with Profound hearing losses produced more errors over-all as well as more errors in each phonological process category. Subjects with Profound hearing losses frequently deleted entire consonant clusters, whereas subjects with Moderate to Severe hearing losses did not. Results are also discussed in relation to normal development.
