The present study investigated the effectiveness of prompted nonspoken language production using two low-tech AAC strategies (i.e., picture symbols and sign language) at indirectly facilitating speech productions in a young child with expressive language delays ("late talker"). A single subject, multiple baseline design was used. Results indicated that prompting either sign or picture-symbol production improved the child's speech output for target words without any direct prompts to speak, but that the two AAC strategies did not differ from one another in effectiveness at indirectly eliciting speech. The improvements associated with both strategies suggest that AAC can be a viable intervention tool to address improved speech in children with expressive delays. The AAC intervention had a clear and rapid effect on the child's spoken word productions, although the child did not produce signs or symbols to criterion for most of the target words before producing them in speech.
本研究调查了使用两种低技术辅助沟通（即图片符号和手语）来间接促进言语表达的非言语语言产生的有效性，以促进一名有表达性语言延迟的幼儿（“晚说话者”）的言语产生。采用单一被试、多个基线设计。结果表明，提示使用手语或图片符号生成可在没有任何直接说话提示的情况下提高儿童对目标词的言语输出，但两种 AAC 策略在间接引出言语方面没有差异。两种策略都能提高儿童的言语表达，这表明 AAC 可以作为一种可行的干预工具，以提高有表达性延迟的儿童的言语能力。尽管在大多数目标词之前，儿童并没有达到符号或手语的标准，但 AAC 干预对儿童的口语产生有明显且迅速的影响。
