[Show abstract][Hide abstract] 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.

[Show abstract][Hide abstract] ABSTRACT: Hearing impaired children do not develop oral speech in the same time with the hearing ones. Cochlear implants may change this situation. Implanted deaf children may develop oral speech but only after long speech rehabilitation. Acquisition of language skills should be assesed correctly in every patient. It is important because this therapy is quite expensive. There are many quantitative and qualitative methods used all over the world. In some cases score is calculated as percentage of correctly repeated words. Sometimes it did not reflect true level of language development. 240 people were implanted in Poznań in years 1994-2004. Two years ago, evaluation of changes in the distinctness and discrimination of phonems of cochlear implants children was begun. We found differences between standard speech audiometry and distinctness and discrimination of phonems.

[Show abstract][Hide abstract] ABSTRACT: There are many tests prepared for speech evaluation for different age groups and with any disabilities. The percent of correct repeated mono- or bisyllabes words create the final result. Sometimes this score is lower than real oral communication skill of CI patient. In the years 1994-2002 in Poznań 158 cochlear implantations were performed. Since few months the evaluation of the distinctness and discrimination of phonems of cochlear implants children are being conducted. It was found some differences between distinctness and discrimination of phonems and discrimination of words. It means that scores achieved by children in standarized words--tests do not reflect the real level of speech development of each child.
