Individuals with autism spectrum disorder (ASD) often have communication support needs and many rely on augmentative and alternative communication (AAC) systems to communicate. Previous research suggests that AAC use does not preclude the acquisition of spoken language and, in some cases, may facilitate improvements in spoken communication in children with ASD. This study systematically applied echoic prompting and manipulated reinforcer magnitude in an effort to increase the spoken requests of 3 children with ASD, ages 10-12 years, who used iPad-based speech generating devices (SGDs). The spoken language (vocal requests) of all 3 participants increased in frequency and 1 participant began using spoken language exclusively, even when the SGD was an option. Implications for practitioners and directions for future research in this area are discussed.
患有自闭症谱系障碍（ASD）的个体通常有沟通支持需求，许多人依靠辅助和替代沟通（AAC）系统进行交流。先前的研究表明，使用AAC并不排除口语的习得，在某些情况下，还可能促进ASD儿童口语交流的改善。本研究系统地应用了回声提示并操纵强化物强度，以增加3名年龄在10至12岁、使用基于iPad的语音生成设备（SGD）的ASD儿童的口语请求。所有3名参与者的口语（发声请求）频率都有所增加，1名参与者甚至在有SGD可供选择的情况下开始完全使用口语。本文讨论了对从业者的启示以及该领域未来研究的方向。
