Voice acoustic characteristics of children with late-onset cochlear implantation: Correlation to auditory performance.

Objectives: To study the voice acoustic parameters of congenitally deaf children with delayed access to sounds due to late-onset cochlear implantation and to correlate their voice characteristics with their auditory performance.

Methods: The study included 84 children: a control group consisting of 50 children with normal hearing and normal speech development; and a study group consisting of 34 paediatric cochlear implant (CI) recipients who had suffered profound hearing loss since birth. According to speech recognition scores and pure-tone thresholds, the study group was further subdivided into two subgroups: 24 children with excellent auditory performance and 10 children with fair auditory performance.
