Abstract

The purpose of this study was to investigate the effect of articulatory intervention using visual phonics to improve the speech intelligibility of children with impaired hearing. The subjects of the study were five hearing impaired children. As per the results of the UTAP articulation tests, five phonemes with the most frequent errors were selected for each child and a total of 10 sessions were provided. The methodology involved analyzing vowel space and related measures (vowel space area, vowel articulatory index, formant centralization ratio, and F2i/F2u ratio) before and after the visual phonics intervention. After the articulation intervention, every child's speech intelligibility improved, their vowel space area was widened, the FCR value decreased, and the F2ratio value increased. These results show that the use of visual phonics through symbolic images and hand clues has a positive effect in terms of improving the speech intelligibility of children with impaired hearing.
