The relationship between functional spectral resolution and vowel recognition performance in pediatric cochlear implant users

Cochlear implants (CIs) can improve the speech perception abilities of adults and children with severe to profound sensorineural hearing loss. However, there is a great deal of variability among CI users’ speech recognition performance. Clinical tests used currently do not give the whole picture cochlear implant users’ struggles in various listening situations. Many linguistic factors can impact the validity of current audiological clinical tests because people calibrate to their devices over time to re-interpret the sounds of speech.There is a need for low-level auditory measures that assess the abilities required for accurate speech recognition, rather than speech recognition ability itself. In the present study, thirteen children with CIs who were implanted at a young age as well as 10 adult CI users performed a test of functional spectral resolution and a vowel recognition task. It is expected that early-implanted, prelingually-deafened children will perform better on the tasks than the later-implanted, post-lingually deafened group of adults. Children and adults with CIs who utilize spectral cues effectively will exhibit high scores on the vowel recognition task. A correlation between these spectral resolution capabilities and the vowel recognition task could indicate an innovative and effective way to clinically assess speech perception outcome abilities for individuals with cochlear implants.

  • To identify a potential factor for the variance in performance in speech recognition abilities in children and adult CI users
  • To reveal a potential correlation between functional spectral resolution abilities and a vowel recognition task
  • To suggest clinical considerations when evaluating a CI user
