Prosody and voice characteristics of children with cochlear implants

Area of Science:

• Speech-Language Pathology
• Audiology
• Pediatric Rehabilitation

Background:

• Children with severe to profound hearing impairments often exhibit challenges in speech prosody and voice production.
• Cochlear implantation is a common intervention aiming to restore auditory function and improve speech outcomes.

Purpose of the Study:

• To analyze the prosody and voice characteristics of conversational speech in young children with severe to profound hearing impairments post-cochlear implantation.
• To identify specific areas of improvement and persistent challenges in speech production.

Main Methods:

• A descriptive, longitudinal study analyzing 40 speech samples from six children fitted with cochlear implants.
• Utilized the Prosody-Voice Screening Profile (PVSP) for detailed acoustic and perceptual analysis.

Main Results:

• Children showed significant issues with stress and resonance quality.
• Difficulties were noted in speech rate, loudness, and laryngeal quality, but not consistently in phrasing or pitch.
• Observed developmental trends in prosody and voice characteristics.

Conclusions:

• Prosody and voice characteristics in this pediatric cochlear implant population differ from typical observations in untreated hearing impairment.
• Cochlear implants demonstrate significant benefits for improving prosody and voice outcomes in children with hearing loss.
