Many children with autism spectrum disorder (ASD) have difficulty developing speech and/or have limited or unintelligible vocal abilities. Often, people with ASD learn to communicate with others using a form of an augmentative and alternative communication (AAC) device called a speech-generating device (SGD). The present study examines the effectiveness of an SGD, Proloquo2Go, on emerging vocalization in a child with ASD.
