Abstract
Background: Children with autism spectrum disorder (ASD) tend to have communication and social interaction deficits. Their impaired communication is derived from difficulties in acquiring language. The use of interactive technologies has been demonstrated to enhance verbal and non-verbal communication, as well as the social interaction tendencies of children with ASD. Artificial intelligence has played a growing role in the habilitation of children with ASD. However, little research exists on the possible roles and effectiveness of virtual voice assistants in developing language and social skills in children with ASD. This study examined the effects of using a voice assistant in children with ASD on two outcomes: speech skills (expressive verbal vocabulary and production of short phrases) and social interaction skills (playing/sharing). Methods: An interventional single-case design study was used to explore this concept using three children with ASD between the ages of 4 and 11 years. The participants used an accessible virtual voice assistant, Apple’s Siri, for three months. Pre- and post-intervention questionnaires and semi-structured interviews with mothers were administered to measure the communication and social interaction skills of the participating children. Results: Participant One, Two and Three showed a notable improvement in the total number of correct words produced with fewer attempts during the VVA intervention compared with the baseline phase. Further, all participants showed increases in the social interactions in the intervention phase, compared with the baseline phase. Finally, all the mothers noted improvement in their children’s speech intelligibility and social interactions. Conclusions: Results showed that the virtual voice assistant had positive effects on the speech and social interaction skills of children with ASD. The findings of this study implied that children with ASD can use readily available voice assistant software to improve their speech and social interaction skills. Furthermore, this study’s findings could be used to develop strategies to increase the availability of artificial intelligence infrastructure in schools and homes to help children with ASD.
