Speech Perception in Children with Cochlear Implants
Cochlear implants provide access to the speech signal in children with hearing loss that often cannot benefit from acoustic hearing aids. However, despite the numerous positive results in pediatric cochlear implantation, published data still indicated a wide range of performance among implant recipients. Hence, a need to study the possible variables that can affect performance, could account fo...
متن کاملCochlear Implants: Signal Processing and Speech Perception
Several million Americans today have profound hearing loss, and for years they had to rely on conventional hearing aids. Although hearing aids have been found to benefit hearing impaired individuals who suffer mild to moderate deafness, they do not seem to provide much benefit to individuals with profound (sensorineural) deafness. Today, a prosthetic device, a cochlear implant, can be implanted...
متن کاملSpeech processing in vocoder-centric cochlear implants.
The principles of the most recent cochlear implant processors are similar to that of the channel vocoder, originally used for transmitting speech over telephone lines with much less bandwidth than that required for transmitting the unprocessed speech signal. An overview of the various vocoder-centric processing strategies proposed for cochlear implants since the late 1990s is provided including...
متن کاملThe Grammatical Abilities in a Speech Sample of Persian-speaking Children With Cochlear Implants
Objectives: Studies reported that children with Cochlear Implant (Cl) presented difficulties in grammatical acquisition. The Persian language is inflectional. The present study aimed to compare word-level inflections in the language samples of CI recipients and healthy-hearing children. Methods: Thirty children were recruited in this descriptive-analytical cross-sectional study. The Language S...
