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.

这项研究的目的是调查具有扩展性和替代性交流（AAC）应用程序向扫盲（T2L）软件功能（即，在网格显示中选择图形符号后输出动态文本和语音）的效果。为说话很少或没有语音的严重自闭症谱系障碍（ASD）的人获得12个个人相关的单字。该研究在四个词集的设计中实现了单主题，多探针，跨单词的设计。这项研究的所有四名参与者都显示出提高阅读目标单词的准确性，并且这项研究的结果提供了初步的证据，表明T2L功能可以积极影响言语能力和读写能力有限的ASD个体的单词学习。
