许多研究表明，语音加工与阅读和拼写技能的习得密切相关。有言语和语言障碍的儿童出现语音处理问题和文学困难的风险似乎更高。然而，并不是所有有言语和语言障碍的儿童都会遇到困难：文献并不清楚哪一组言语和语言障碍儿童受到的影响最严重，也不清楚语音处理的哪些方面最有可能受到损害。采用严格的主题选择来比较四组20名6岁左右的儿童的表现：言语障碍（言语）；语言障碍(语言);言语及语言障碍（混合）；和语言发育正常的儿童（正常），通过使用一系列的语音处理任务。这一结果支持了一项研究，即言语和语言障碍儿童的语音处理能力比普通人弱。这个样本中的所有受试者似乎都有风险：混血儿表现出最大的困难，其次是语言组，正常组表现最好。虽然语言组作为一个整体表现明显比正常组差，但它由两个水平的表现组成，事后分析表明，这两个水平的表现与孩子表现出的语言障碍模式有关。
Phonological processing has been shown by many researchers to be strongly related to the acquisition of reading and spelling skills. Children with speech and language impairment appear to be at increased risk for phonological processing problems and hence literary difficulties. However, not all children with speech and language impairment experience difficulties: the literature is not clear as to which groups of speech and language impaired children are most severely affected nor which aspects of phonological processing are most likely to be impaired. Rigorous subject selection was employed to compare the performance of four groups of 20 children, aged approximately 6 years: speech-impaired (Speech); language-impaired (Language); speech and language impaired (Mixed); and children with normally developing language (Normal), by use of a battery of phonological processing tasks. The results supported the research that has shown speech and language impaired children to have weaker phonological processing skills than the general population. All the subjects in this sample appeared to be at risk: the Mixed children demonstrated the most difficulty, followed by the Language group, with the Normal group performing the best. Whilst the Speech group as a whole performed significantly more poorly than the Normal group, it consisted of two levels of performance which, on post hoc analysis were shown to relate to the pattern of speech impairment exhibited by the child.
