Area of Science:

  • Audiology
  • Speech-Language Pathology
  • Linguistics

Background:

  • Cochlear implants (CI) aid communication in deaf children but voice quality often differs from normal-hearing peers.
  • Objective and subjective voice analysis are crucial for understanding CI users' speech development.

Purpose of the Study:

  • To compare the voice characteristics of children with cochlear implants (CI) to those of normal-hearing children.
  • To identify specific acoustic and perceptual differences in the speech of CI users.

Main Methods:

  • Compared voice parameters (pitch, intensity, fluency, pauses, articulation, pleasantness, formants, duration) between a group of 8 children with CI and a control group.
  • Utilized the French standard text 'La bise et le soleil' for phonetic material analysis.

Main Results:

  • Significant differences observed in intensity variations between CI users and the control group.
  • Voice formants in CI users were not within typical normal ranges, though assessment was challenging.
  • The most prominent difference was in speaking duration, with CI users exhibiting altered speech timing.

Conclusions:

  • Cochlear implant use impacts speech production, particularly in terms of intensity modulation and speaking duration.
  • The findings highlight areas for targeted intervention in speech rehabilitation for children with CI.
  • Further research using this methodology can refine CI speech therapy strategies.
