Longitudinal formant analysis after cochlear implantation in school-aged children

Abstract

Fair improvement of articulation after cochlear implant was demonstrated by the F1-F2 gram analysis. This procedure can be used for data sharing and cooperation between medical and educational specialists.

“…This is what others have also previously mentioned [1-3,6,9,25] and [26]. In table 2 we have also shown that the children who are implanted at earlier ages, attain higher levels of speech with fewer abnormalities in their voice, which is reported by Eberhard as well [5].…”

Control of speech and voice in cochlear implant patients

“…Following implantation in adults, there is a gradual expansion of the formant space that results in improved contrasts between vowels . Similar results are present in implanted prelingually deaf children . These changes not only lead to more distinct vowel contrasts but also result in vowels that are more similar to those expected from age‐matched peers .…”

“…36,48,51 This is surprising given that CIs provide better access to high-frequency sound components. Improvements in vowels can be seen as early as 2 weeks, 19 although other studies have not found effects until 2 months, 50 in contrast to the more immediate changes noted above for vocal pitch.…”

[48][49][50][51] These changes not only lead to more distinct vowel contrasts but also result in vowels that are more similar to those expected from age-matched peers. 17,[46][47][48]50 Interestingly, vowel changes appear to more specifically involve F1 decreases, with F2 changes being more variable in adults 17,18,23 and children.…”
