Abstract

This study aimed to extend the literature on VOCA as a means of producing increased verbal speech using a prompt delay and shaping methods. Intervention targeted novel vocalization for three children with autism spectrum disorder (ASD) and limited vocal speech. All three participants increased vocalizations, but to varying degrees and only after a second phase where an echoic prompt was introduced. While the results vary across participants, increased vocal speech for all participants and high social validity suggest that VOCA-based interventions may be an appropriate intervention to increase vocal output for children with ASD.
