title: [Evaluation of phonemic hearing development in CI-patients].
abstract: Phonemic hearing it is a typical interdisciplinary problem. Many specialists like pedagogues, psychologists, phoniatricians and speech therapists are interested in this field. So, we may find many definitions describing this kind of hearing. The speech perception and acquisition of speech is a difficult process profoundly hearing impaired children. With the development of the cochlear implant, acoustic input can be provide to these children. Studies documenting the postoperative performance of children with implants have generally shown significant improvements in speech perception and production. On the opposite side--in the group of postlingually deafened adult the speech rehabilitation is quite short. Only a few specialists described their observation about phonemic hearing development in CI-patients. How do it differ from hearing development in healthy population? The aim of this study was to describe the phonemic hearing development in CI-patients. In the ENT Dept. of University of Medical Sciences in Poznań 280 cochlear implantation were performed. They were observe in three groups: pre-, peri- and postlingually deafened ones. We concluded the same order of phonemic hearing development in every group. The time of acquisition differed, and depended of oral language development before implantation. At first they start to distinct voiced and unvoiced phones, than oral-nasal and sharp-soft ones. The most difficult for them was to discriminate fricative and plosive sounds.
