Abstract

Objective: This study is to examine the final cluster processing in Cochlear implanted child and compare the hearing age factor with the chronological age one. Introduction: Scholars argue that, in a Cochlear Implanted (CI) child, the hearing age is the crucial factor in the speech rather than the chronological age. To determine which factor affects the production more, we examined the mastery of Persian final consonant clusters realization in CI children at one-to-two years of hearing experience and compared the result to Normal Hearing (NH) peers. Methods and materials: The study included 21 children in two categories of girls and boys. Using picture-naming task, we collected the data from participants. Result: Data analysis showed that all the children used the same set of phonological rules at their developmental stages of word final consonant cluster but the distribution of preferences differed between the groups. In one hand, Cluster reduction was the most produced phonological rule in both groups and on the other hand, CI children preferred breathing, coalescence and cluster simplification more than NH children did. Considering Gender, unlike NH girls and boys who had the same trend in their phonological system, CI girls were closer to complete production rather than boys. Conclusion: According to this survey, what seems to be important in speech production of CI children is years of hearing experience rather than chronological age. Girls tried different rules compared to boys for cluster production, but when the mastery over cluster production was achieved, there was no difference between girls and boys. © 2018 Elsevier B.V.
