Comparison Study of the Pronunciation of Vietnamese Phonemes (Vowels and Consonants) by Pre-School Deaf Children Before and After Cochlear Implantation (Case Study)

Van Tu Anh [2]


Abstract: By comparing the hearing and pronunciation abilities of deaf children at 2 time points (before and after cochlear implantation), this study aims to show the impact of cochlear implantation on the hearing and speaking quality of hearing-impaired children in private lessons of the pre-school deaf children in Vietnam, through the case of Hanoi Sunny AVT Therapy Center. The study was conducted on the basis of surveying 25 pre-school deaf children at the Center, with profound and severe deafness (22 children with profound hearing loss and 3 with severe deafness). Research data included notes, recordings and videos of children's ability to hear and pronounce Vietnamese vowel and consonant phonemes before and after cochlear implantation. The results of the comparative study have shown that cochlear implantation has helped deaf children to pronounce Vietnamese phonemes (vowels and consonants) much better than before implantation.
