Today, cochlear implant provides an appropriate opportunity for the development of speech and language in children. In some studies, the age of children at the time of surgery has been stated as the most important factor in the development of speech and language of children after cochlear implant, while in other studies factors, including participation in rehabilitation programs, parental educational level, and lack of other disability have been regarded as key factors in the development of speech and language in these children. This review aims to assess the conducted studies in Iran to identify factors contributing to improving the auditory perception, language, and other skills in children with cochlear implants in comparison to children with normal hearing. The purpose of this study is to review the results of studies conducted on speech and language abilities in children with cochlear implant compared to the normal group in Iran. Directory of Open Access Journals, Google Scholar, PubMed (NLM), LISTA (EBSCO), and Web of Science have been searched. cochlear implants in deaf children before language learning results in the acquisition of speech and language skills in children. Timely detection of hearing impairment, early implantation, duration of hearing, and parental involvement in the rehabilitation process are important factors that affect the development of speech and language. The child's age at the time of implantation, continued participation in rehabilitation programs and the lack of associated problems directly impact the development of auditory perception, speech and language of children with cochlear implant while family education level indirectly impacts this developmental process.
