我们研究了发展性阅读障碍或特殊语言障碍（SLI）学龄儿童的分类言语知觉，并与年龄匹配的年轻对照组进行比较。刺激由合成语音标记组成，其中发音位置从“B”到“d”不等。孩子们被测试分类，分类噪音，和歧视。语音意识技能也进行了评估，以检查这些是否与言语感知措施。我们在所有组中观察到类似的良好基线分类率;然而，当添加噪音时，SLI组相对于对照组显示出受损的分类，而睡眠障碍儿童显示出完整的轮廓。SLI组的类别间区分率比预期的差，而这种模式在睡眠障碍组中只是边缘性的。受损的语音意识配置文件中观察到的SLI和诵读困难组，然而，语音意识和言语知觉分数之间的相关性并不显着。研究结果表明，在有语言和阅读障碍的儿童中，接受性语言和言语感知之间存在显著的关系，阅读和言语感知之间的关系充其量是微弱的，而且语音和言语感知缺陷之间的关系确实非常复杂。
We examined categorical speech perception in school-age children with developmental dyslexia or Specific Language Impairment (SLI), compared to age-matched and younger controls. Stimuli consisted of synthetic speech tokens in which place of articulation varied from 'b' to 'd'. Children were tested on categorization, categorization in noise, and discrimination. Phonological awareness skills were also assessed to examine whether these correlated with speech perception measures. We observed similarly good baseline categorization rates across all groups; however, when noise was added, the SLI group showed impaired categorization relative to controls, whereas dyslexic children showed an intact profile. The SLI group showed poorer than expected between-category discrimination rates, whereas this pattern was only marginal in the dyslexic group. Impaired phonological awareness profiles were observed in both the SLI and dyslexic groups; however, correlations between phonological awareness and speech perception scores were not significant. The results of the study suggest that in children with language and reading impairments, there is a significant relationship between receptive language and speech perception, there is at best a weak relationship between reading and speech perception, and indeed the relationship between phonological and speech perception deficits is highly complex.
