The purpose of this study was to investigate the effects of an augmentative and alternative communication (AAC) app with transition to literacy (T2L) software features (i.e., dynamic text and speech output upon selection of a graphic symbol within the grid display) on the acquisition of 12 personally relevant single words for individuals with severe autism spectrum disorder (ASD) who had minimal or no speech. The study implemented a single-subject, multiple-probe, across word sets design with four participants. All four participants in this study demonstrated increased accuracy reading targeted single words and results from this study provide preliminary evidence that the T2L features can positively affect the single-word learning of individuals with ASD who have minimal speech and limited literacy skills.

本研究的目的是调查具有读写能力转换 (T2L) 软件功能（即在网格显示中选择图形符号时动态文本和语音输出）的增强和替代通信 (AAC) 应用程序对为患有严重自闭症谱系障碍 (ASD) 且言语能力极少或没有言语的患者获取 12 个与个人相关的单个单词。该研究采用了单主题、多探针、跨词集设计，有四名参与者。这项研究的所有四名参与者都证明了阅读目标单词的准确性有所提高，并且这项研究的结果提供了初步证据，表明 T2L 功能可以对言语能力和识字能力有限的自闭症谱系障碍患者的单词学习产生积极影响。
