Purpose This study compared perception of consonants in medial position by preschoolers, with and without speech sound disorder (SSD), with similar vocabulary and language skills. In addition, we investigated the association between speech perception and production skills. Method Participants were 36 monolingual English-speaking children with similar vocabulary and language skills, half with SSD and half with typical speech and language development (TD). Participants completed a speech perception task targeting phonemes /p, k, s, ɹ/ in /aCa/ disyllables and a comprehensive battery of speech and language measures. Results Children with SSD were significantly less accurate in perceiving speech sound distinctions relative to peers with TD. The phoneme /p/ was perceived significantly more accurately than the three other target phonemes. The correlation between overall perceptual accuracy and overall production accuracy was significant. Furthermore, perceptual accuracy of targets /k, s, ɹ/ was significantly correlated with production accuracy of these phonemes. Conclusions Many children with SSD have greater difficulty perceiving the specific speech sounds they misarticulate. Nonetheless, most children with SSD present with broader perceptual difficulties than peers with TD with similar vocabulary and language skills.

有和没有言语障碍的学龄前儿童对内侧辅音的感知

目的这项研究比较了有或没有言语障碍（SSD）、词汇和语言技能相似的学龄前儿童对中间位置辅音的感知。此外，我们还研究了言语感知和生产技能之间的关联。 方法参与者是 36 名单语英语儿童，他们具有相似的词汇和语言技能，其中一半患有 SSD，一半具​​有典型的言语和语言发展 (TD)。参与者完成了针对 /aCa/ 双音节中的音素 /p、k、s、ɹ/ 的语音感知任务以及一系列全面的语音和语言测量。 结果与患有 TD 的同龄人相比，患有 SSD 的儿童在感知语音差异方面的准确度明显较低。音素 /p/ 的感知明显比其他三个目标音素更准确。总体感知准确性和总体生产准确性之间存在显着相关性。此外，目标/k、s、ɹ/的感知准确性与这些音素的生成准确性显着相关。 结论许多患有 SSD 的儿童在感知他们错误表达的特定语音时会遇到更大的困难。尽管如此，大多数患有 SSD 的儿童比具有类似词汇和语言技能的 TD 儿童表现出更广泛的感知困难。
