This paper studies the developmental stages of word initial consonant clusters (CCs) in the speech of six monolingual Israeli Hebrew (IH) acquiring hearing impaired children using cochlear implant (CI). Focusing on the patterns of cluster reduction, this study compares the CI children with typically-developing hearing children. All the CI children, three boys and three girls with age ranged from 1;5-2;8 years at their first recording session, were with pre-lingual hearing impairment with bilateral sensorineural hearing loss. Productions of word initial CCs were elicited in an isolated-word picture-naming task combined with spontaneously produced words. Data collection started 2-4 months after implantation and continued until the correct production of word initial biconsonantal clusters. Results reveal that both the developmental stages and reduction patterns of word initial CCs of the CI children are very similar to typically-developing IH acquiring children, thus supporting earlier studies which show that children with CIs follow the same stages of acquisition as hearing children.
