Articulation Production Ability and the Phonological Pattern of Profound Hearing Impaired Children who Are at Different Education Condition

교육환경이 다른 학령기 고도난청아동의 음소 산출능력과 그 음운패턴의 변화

This study was designed to evaluate the phonological characteristics in profound hearing-impaired children. 10 males and 10 females participated in this study and all were prelingually hearing impaired. 7 children were educated at deaf school and 13 children at general elementary school with private clinic. Their hearing levels were more than 95dB HL and did not appear any wave by ABR. The results can be summarized as following: The articulation accuracy of hearing impaired children was 54.19% and most distinguished phonological patterns of the hearing impaired children were alveolarization and stop assimilation. The accurate articulation phonation was significantly different from education system between deaf school and general school. The error articulation degrees in profound hearing impaired children at general school seemed meaningfully smaller than those in hearing impaired children at deaf school.
