A cochlear implant is an option given to children and adults with the severe-to-profound sensorineural hearing loss. Cochlear implants (CI) provide a greater assistance for speech perception abilities when severe-to-profound hearing loss reduces the amount sensory information necessary to understand speech. Therefore, the earlier a child is exposed to speech, the better speech perception outcomes and the closer they can get to their peers in these developmental stages. Depending on the age of implantation, the benefits of speech and language development might differ in children. This is why the age of implantation has a significant impact on speech perception. Aspects of speech perception that were examined include the age of implantation effect
