摘　　要：目的 探究听障儿童塞音嗓音起始时间特点及与呼吸能力的相关性,为其塞音的习得及矫正提供依据。方法 选取3~5岁听障儿童及健听儿童各20例,录取6个塞音(/b/、/p/、/d/、/t/、/g/、/k/)与3个单元音(/a/、/i/或/e/、/u/)所组成的18个辅-元(consonant vowel,CV)音节,声调均为一声,提取嗓音起始时间(voice onset time,VOT)。对两组儿童进行最长声时(maximum phonation time,MPT)测试并对VOT与MPT相关性进行分析。结果 在不送气塞音中,听障儿童/da/的VOT值显著大于健听儿童(P<0.05),其余音节的VOT值均无显著差异(P>0.05);在送气塞音中,听障儿童所有音节VOT值均显著小于健听儿童(P<0.05);听障儿童的MPT显著小于健听儿童(P<0.05);送气塞音VOT值与MPT均呈显著正相关(P<0.05,r>0)。结论 听障儿童的呼吸能力显著弱于健听儿童,需要加强呼吸训练,有利于听障儿童送气塞音的学习。Objective To explore the characteristics of the onset time of the plosive voice of hearing-impaired children and its correlation with breathing ability, so as to provide a basis for the acquisition and correction of plosives. Methods 20 hearingimpaired children aged 3-5 years and 20 hearing children of similar age were selected. 18 consonant vowel(CV) syllables composed by 6 stops(/b/,/p/,/d/,/t/,/g/,/k/) and 3 monophonic sounds(/a/,/i/or/e/,/u/) were selected, the tones are all the first tones, and the voice onset time(VOT) value is extracted. At the same time, maxium phonation time(MPT) was performed on the two groups of children and the correlation between VOT and MPT was analyzed. Result In the unaspirated plug sound, the VOT value of/da/of hearing-impaired children was significantly greater than that of hearing children(P<0.05), and there was no significant difference in the VOT value of the rest syllables(P>0.05). In aspirated stop sounds, the VOT values of all syllables tested by hearing-impaired children were significantly lower than those of hearing children(P<0.05). The MPT of hearing-impaired children was significantly lower than that of hearing children(P<0.05). Both the VOT value of aspirated stop sound and MPT showed a significant positive correlation(P<0.05, r>0). Conclusion The breathing ability of hearing-impaired children is significantly weaker than that of hearing children, and they need to strengthen breathing training, which is conducive to the learning of aspiration stop sound.
