The present study investigates the acoustic characteristics of Greek vowels produced by hearing-impaired children with profound prelingual hearing loss and cochlear implants. The results revealed a significant difference between vowels produced by hearingimpaired children and those produced by normal-hearing ones in terms of duration. Stressed vowels were significantly longer than non-stressed for both groups, while F0, F1 and F2 did not differ significantly between the two groups for any vowel, with the exception of /a/, which had significantly higher F1 when produced by hearingimpaired children. Acoustic vowel spaces were similar for the two groups but shifted towards higher frequencies in the low-high dimension and somehow reduced in the front-back dimension for the hearing-impaired group.
