Cochlear implant as an important factor of the development of prosodic features in prelingually deaf children under 2 years of age
JHS 2011; 1(3): EA73-75
Background: Profound prelingual hearing impairment has a substantial influence on child development, particularly on their ability to linguistic communication. In lingual communication, the prosodic features play a basic role because they are responsible for proper speech reception. The prosodic aspect of speech is disturbed in people with hearing disability and is involved with communication deficit. Cochlear implantation has become a method that reinforced appropriate language development in children with prelingual deafness. The majority of the young cochlear users can develop substantial language skills. However, whether those children do also develop communication skills such as the prosodic aspects of the language, remains an open problem.
Material and Methods: A group of 28 prelingually hearing-disabled children, about one year old, implanted or equipped with hearing aids, respectively, was investigated. The research was based on the comparison between recorded language statements, particularly its prosodic aspects, in both children’s groups. The collected data were evaluated by the listening method with the aid of the prosodic scale 0-5.
Results: The development of the prosodic features in children using implants is significantly greater than in those who use hearing aids.
Conclusion: Preliminary results demonstrate an important role of the cochlear implant in the development of the prosodic features. It is very likely that the use of cochlear implants will equalize the lingual communication of hearing impaired children to that of hearing children.
