Cochlear Implants in Children With Profound Hearing Loss.

American journal of audiology·2015

Multichannel cochlear implants significantly improved speech production in most children. Over two-thirds showed gains in imitating sounds and overall speech intelligibility, aiding language development.

Area of Science:

  • Audiology
  • Speech-Language Pathology
  • Biomedical Engineering

Background:

  • Cochlear implants are vital for hearing restoration in children.
  • Assessing speech production is crucial for evaluating cochlear implant efficacy.
  • The Nucleus multichannel cochlear implant is a widely used device.

Purpose of the Study:

  • To evaluate the impact of the Nucleus multichannel cochlear implant on speech production in children.
  • To analyze improvements across various speech domains, including segmental and nonsegmental features.
  • To compare speech production with the device on versus off.

Main Methods:

  • Collected speech production data from 61 children (ages 2.4-17.8) using five protocols.
  • Assessed nonsegmental and segmental aspects of speech, phonologic skills, and intelligibility.

  • Included an experimental condition comparing speech with the processor on and off.

    • Main Results:

    • 77% of children improved in at least one-third of speech production measures.
    • 66.7% improved in speech sound imitation, and 55.6% in phonologic skills.
    • Speech intelligibility improved in 62.9% of children; vowel acoustics differed with processor on/off.

    Conclusions:

    • Multichannel cochlear implantation demonstrates significant benefits for children's speech production.
    • Improvements are noted across various speech aspects, including prosody, phonology, and intelligibility.
    • The device appears to positively influence the acoustic characteristics of speech production.
