This article presents the results of an acoustic analysis of vowels and plosives/affricates produced by 45 Mandarin-speaking children with hearing impairment. Vowel production is represented and categorized into three groups by vowel space size calculated with normalized F1 and F2 values of corner vowels. The correlation between speech intelligibility and language abilities assessed by the level of word comprehension and the complexity of sentence structure is statistically significant. Vowel space grouping is correlated with speech intelligibility and spike percentage of plosives/affricates production. The generalized linear model analysis also shows that the level of word comprehension and the degree of hearing loss are the two most significant factors in predicting speech intelligibility. The statistical results suggest that the interplay of acoustic characteristic and speech ability is complex.
本文呈现了对45名患有听力障碍的讲普通话儿童所发元音及塞音/塞擦音的声学分析结果。元音发音通过用角元音的归一化F1和F2值计算出的元音空间大小来表示并分为三组。通过单词理解水平和句子结构复杂性评估的言语可懂度与语言能力之间的相关性具有统计学意义。元音空间分组与言语可懂度以及塞音/塞擦音发音的尖峰百分比相关。广义线性模型分析还表明，单词理解水平和听力损失程度是预测言语可懂度的两个最重要因素。统计结果表明，声学特征与言语能力之间的相互作用是复杂的。
