摘要

BACKGROUND: Cochlear implantation is effective treatment for hearing impaired children who gain little or no benefit from hearing aids. The development of intelligible speech is a key outcome measure for pediatric cochlear implantation. This study assessed speech production in deaf children with cochlear implants. Speech intelligibility was compared between normal-hearing and cochlear-implanted children. The relationship between speech intelligibility, age at implantation and the duration of implant use was also evaluated.
METHODS: Twenty-six children with cochlear implants, with an average post-implantation duration of 2.45 years were enrolled in this study. Speech intelligibility was determined by normal-hearing listeners using recorded speech based on the assessment of scores for the intelligibility of words, phonemes (vowel and consonant) and tones. The scores were compared to results of the age-matched control subjects with normal hearing. The relationship between speech intelligibility, age at implantation and the duration of implant use was evaluated by linear regression analysis.
RESULTS: The differences of speech intelligibility between cochlear-implanted and normal-hearing children were assessed by the ratio (cochlear implant group/normal group) of the average correct perception rate in words (42.5%), consonants (64.9%), vowels (73.5%), and tones (72.3%). These differences were all significant between the two groups (p＜0.001). After adjustment with the linear regress ion formula in the normal-hearing group, the speech intelligibility of the implanted group showed negative correlation with the age at implantation but positive correlation with the duration of implant use.
CONCLUSION: The speech intelligibility of deaf children with cochlear implants was poorer than that of children with normal-hearing, including words, phonemes and tones. The results of this study suggest that speech intelligibility will be better if the age at implantation is younger or the period of implant use is longer.
