Speech perception abilities in children with cochlear implants or hearing aids

Area of Science:

• Audiology
• Speech-Language Pathology
• Pediatric Medicine

Background:

• Auditory perceptual development is crucial for speech development in children with hearing impairments.
• Cochlear implants (CIs) and hearing aids are key assistive technologies for profound hearing loss.
• The impact of communication modality on speech perception outcomes requires further investigation.

Purpose of the Study:

• To evaluate the effect of communication method on speech perception skills in children with hearing impairments.
• To compare speech perception abilities between children using cochlear implants and those using hearing aids.
• To identify differences based on educational settings (oral vs. total communication).

Main Methods:

• Sixty-eight prelingual, profoundly hearing-impaired children participated.
• Participants used either hearing aids or cochlear implants.
• Five standardized speech perception measures were administered, assessing pattern, word, and speech recognition.

Main Results:

• Significant differences in speech perception were observed between oral and total communication settings.
• The educational setting had a greater effect on hearing aid users compared to cochlear implant users.
• Children with multichannel cochlear implants demonstrated higher scores on specific tests than single-channel implant or hearing aid users.

Conclusions:

• Communication method and educational setting play a vital role in speech perception development for hearing-impaired children.
• Cochlear implants, particularly multichannel devices, may offer advantages in speech perception outcomes.
• Findings support optimizing communication strategies and technology selection for enhanced auditory rehabilitation.
