OBJECTIVES: Normal hearing system is an essential factor for accurate production of speech segments. It seems that cochlear implant prosthesis helps children with hearing impairment to speak more accurately than before receiving prosthesis. The current research aimed to compare the vowel duration in school-aged children with cochlear implants and that in children with normal hearing. Additionally, the performance of girls and boys in two groups were investigated.
METHODS: A cross-sectional and descriptive-analytical study was carried out to compare the vowel duration in 9- to 12-year-old children with cochlear implant and those with normal hearing. Participants were 52 children who were matched by age and sex. We asked the children to read the target words with each word including one vowel and then participants' voice samples were recorded. Then, vowel duration was measured using Praat software. Finally, the vowel duration was compared between the two groups running independent sample t-test. The level of significance was (P < 0.05).
RESULTS: There was no statistically significant difference observed between the two groups in the mean values of the vowel duration for the six Persian vowels (P > 0.05). Also, no significant difference was found between boys and girls in the mean value of the vowel duration between the two groups (P > 0.05).
CONCLUSION: Persian vowels in school-aged children with cochlear implant and with typical hearing are produced with similar durations. This finding is probably related to the increased duration of using prosthesis in this age range and speech mode used to measure vowel duration in the present study.
