Abstract:
Objective To investigate the characteristics of auditory recognition ability of Chinese phonetics in children with intellectual disabilities.Methods A total of 22 children aged 8 to 18 years(mean age 13.5±1.89 years)with intellectual disability and 22 typically developing children aged 3 to 6 years(mean age 4.54±0.77 years)were selected as subjects.The intelligence level of the children in the two groups was matched,and the audi-tory recognition ability of the children in the two groups was investigated by using 36 pairs of core phonemes includ-ed in the Articulation and Speech Ability Assessment Tool.Independent sample t test was used to compare the differences in the auditory recognition ability between the two groups.Results ① In consonant auditory recogni-tion,the total consonant phoneme contrast of the children with intellectual disability was 86.03％±6.98％,which was significantly lower than that of typically developing children(95.52％±2.86％)(t(42)=-5.898,P＜0.01).The scores of the other 7 items were significantly lower than those of typically developing children(P＜0.05),ex-cept for the constrast between fricative vs non-fricative,affricate vs fricative.② In vowel auditory recognition,the total phoneme contrast of children with intellectual disability was 88.18％±8.71％,which was significantly lower than that of typically developing children 96.36％±3.24％(t(42)=-4.129,P＜0.01).Among them,the phoneme contrast scores of anterior and posterior nasal vowels were significantly lower than those of typically developing chil-dren(t(42)=-3.196,P＜0.01).③ In tone auditory recognition,the total tone phoneme contrast of children with intellectual disability was 90.40％±12.02％,which was significantly lower than that of typically developing chil-dren 98.48％±3.90％(t(42)=-2.998,P＜0.01).Among them,the contrast between the first and third tones was significantly lower than that of typically developing children(t(42)=-3.196,P＜0.01).Conclusion Children with intellectual disabilities exhibit varying clegrees of difficulty in recognizing consonants,vowels,and tones in Chinese phonetics.Among them,the barrier in consonant recognition is reflected in the contrast recognition of most consonant phoneme pairs.The difficulty of vowel recognition is reflected in the contrast recognition between anterior and posterior nasal vowel.The difficulty of tone recognition is reflected in the contrast recognition between the first and third tone.
