Abstract
Objective To study the consonant pronunciation characteristics and differences between hearing-impaired and normal-hearing children aged 3-5.Methods 110 hearing-impaired children receiving rehabilitation more than half a year and 37 normal-hearing children aged 3 to 5 were enrolled in this study. The chinese Articulation Ability Test was conducted to analyze the accuracy of consonant pronunciation.Results The consonants with articulation accuracy over 80% in hearing-impaired children included/b/,/m/,/d/,/n/,/h/;those with accuracy between 60%-80% included/p/,/t/,/j/,/x/,/f/,/l/,/q/,/r/;Those with accuracy less than 60% included/g/,/k/,/sh/,/zh/,/ch/,/s/,/z/,/c/. The accuracy of consonant pronunciation in normal-hearing children reached more than 85%.The ranking of consonant articulation accuracy for different articulation position from high to low was bilabial>blade-alveolar>alveo-palatal>velar>labiodentals>blade-palatal>supradental;the ranking of articulation accuracy for different manner of articulation from high to low was: nasal consonant>unaspirated stops>aspirated stop>lateral>fricative>unaspirated affricati>aspirated affricate.Conclusion The accuracy of the consonant pronunciation in hearing-impaired children is lower than that in normal-hearing children. Hearing-impaired children should receive a continuous and targeted articulation training, and the training should be carried out based on the difficulty and visibility of consonants.关键词
