Cochlear implant (CI) users

Area of Science:

  • Auditory Neuroscience
  • Speech Production
  • Human-Computer Interaction

Background:

  • Cochlear implants (CIs) restore hearing but can impact vocal control.
  • Previous studies show CI users adjust voice pitch with auditory feedback shifts during sustained vowels.
  • The ecological validity of sustained vowel tasks for assessing CI user vocal control is questioned.

Purpose of the Study:

  • To investigate the relationship between vocal control in sustained vowel production and singing for cochlear implant (CI) users.
  • To determine if sustained vowel tasks accurately reflect real-world vocal control in CI users.

Main Methods:

  • Vocal control was assessed in 10 CI users across two tasks: sustained vowel production and singing.
  • Vocal control was quantified by measuring the variability of fundamental frequency (pitch).

Main Results:

  • Vocal control, measured by fundamental frequency variability, was significantly correlated between sustained vowel production and singing tasks.
  • Vocal variability was significantly higher during singing compared to sustained vowel production.
  • Sustained vowel tasks may overestimate vocal control in CI users.

Conclusions:

  • Vocal control in sustained vowel tasks is related to vocal control in more ecologically valid tasks like singing for CI users.
  • Sustained vowel production tasks may not fully represent the complexities of vocal control in real-world scenarios for CI users.
  • Further research is needed to understand the nuances of vocal control in CI users across diverse tasks.
