Background:
Profound prelingual hearing impairment has a substantial influence on child’s development, particularly on its linguistic communication ability. In language 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 reinforces appropriate language development in children with prelingual deafness. The majority of young cochlear users can develop substantial language skills. However, whether these children develop as well the communication skills, such as the prosodic aspects of the language, remains an open question.

Material and Methods:
A group of 28 prelingually hearing-disabled children, all at about one year of age, either implanted or equipped with hearing aids, 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 better than in these using hearing aids.

Conclusions:
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 language communication of hearing impaired children to that of hearing children.
