The purpose

A cochlear implant is a device for the rehabilitation of severe to profound hearing loss. Despite the standardization of surgical procedures and rehabilitation, speech discrimination performance varied significantly in cochlear implant users and could be improved by early individualized cares. However, there is no objective method yet to evaluate phonemes discrimination, especially in infants, which account for more than half of the indications for implantation. In electroencephalography (EEG), it is possible to highlight the discrimination of auditory stimuli studying the wave of MisMatch Negativity (MMN). In this work, this study propose to use the MMN as an objective vocal audiometry method to evaluate the ability to discriminate phonemes, the smallest units of oral language, in adult cochlear implant users.
