The present study investigated the relationship between lexicon and grammar in individuals who use graphic symbol-based aided augmentative and alternative communication (AAC). Data came from 60 transcripts of generalization sessions that were part of two previous intervention studies, aimed at improving the expressive vocabulary and grammar of 12…

Background: There is a global need for synthetic speech development in multiple languages and dialects, as many children who cannot communicate using their natural voice struggle to find synthetic voices on high-technology devices that match their age, social and linguistic background. Aims: To document multiple stakeholders' perspectives…

Communication deficits have a substantial impact on quality of life for individuals with Angelman syndrome (AS) and their families, but limited qualitative work exists to support the necessary content of measures aiming to assess communication for these individuals. Following best practices for concept elicitation studies, we conducted individual…

Children with partially intelligible speech and language difficulties are often provided with speech-generating devices (SGDs) to support their spoken communication. However, little is known about how SGDs can be used best to facilitate language development. This study evaluated the effects of a conversation-based intervention using SGDs, on the…

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 Autism Spectrum Disorder (ASD). We examined effects of using Virtual Voice Assistant (VVAs) in children with ASD with respect to two outcomes: speech skills and social interaction…

This study explored performance on expressive and receptive graphic symbol tasks and spoken comprehension by individuals who use augmentative and alternative communication (AAC) as well as the relationship of performance with participants' skills and characteristics. Participants were 19 children and youth (aged 5- to 18-years-old) who used aided…

Understanding typical preschoolers' perceptions of communication modes could help guide augmentative and alternative communication (AAC) intervention for preschoolers with autism spectrum disorder (ASD). This study explored the perceptions of 16 typically developing preschoolers toward an (a) AAC application (app) on a tablet, (b) picture exchange…

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…

Purpose: As is the case with children who rely on spoken language, speech-language pathologists must support and track the expressive language development of children with complex communication needs who use graphic symbols to communicate. This research note presents a framework of the progression of expressive English sentence development using…

This study examines interactions between students with atypical motor and speech abilities, their teachers, and eye tracking devices under varying conditions typical of educational settings (e.g., interactional style, teacher familiarity). Twelve children (aged 4-12 years) participated in teacher-guided sessions with eye tracking software that are…

Spinal Muscular Atrophy is a genetic, degenerative disorder, in which individuals become unable to engage in typical motor activities, including speech. The outcome for the most common type of SMA (Type 1), has previously been death before the age of 2, but new medical improvements are showing promising results for life longevity. Research has…

In language learning, aided language modeling refers to the method by which communication partners provide models of the communication system used by individuals with complex communication repertoires that involving both symbols and speech. Providing aided language models creates opportunities for individuals with complex communication repertoires…

Purpose: This study aimed to explore the feasibility of a telepractice communication partner intervention for children who use augmentative and alternative communication (AAC) and their parents. Method: Five children (aged 3;4-12;9 [years;months]) with severe expressive communication impairments who use AAC and their parents enrolled in a…

Previous research by Williams, Siegel and Mazefsky (2018) investigated the relationship between verbal abilities and problem behaviors using data from the Autism Inpatient Collection (AIC). This research found a weak and inconsistent association between verbal abilities and problem behavior severity; however, adapting/coping scores were…

Clinical Question: Do children with complex communication needs show greater improvement in requesting behaviors with the Picture Exchange Communication System® (PECS®) versus a speech-generating device (SGD)? Method: Systematic Review. Sources: Cumulative Index to Nursing and Allied Health Literature (CINAHL), Education Resources Information…
