Development of voicing categorization in deaf children with cochlear implant

摘要

Cochlear implant (CI) improves hearing but communication abilities still depend on several factors. The present study assesses the development of voicing categorization in deaf children with cochlear implant, examining both categorical perception (CP) and boundary precision (BP) performances. We compared 22 implanted children to 55 normal-hearing children using different age factors. The results showed that the development of voicing perception in CI children is fairly similar to that in normal-hearing controls with the same auditory experience and irrespective of differences in the age of implantation (two vs. three years of age).
