Amyotrophic lateral sclerosis (ALS) commonly results in the inability to produce natural speech, making speech-generating devices (SGDs) important. Historically, synthetic voices generated by SGDs were neither unique, nor age- or dialect-appropriate, which depersonalized SGD use. Voices generated by SGDs can now be customized via voice banking and…

The relationships between the use of nouns and verbs, and other word classes have been well established in the typical language development literature. However, questions remain as to whether the same relationships are seen in the language use of individuals who use graphic symbol-based augmentative and alternative communication (AAC). The aim of…

Earlier research shows an arrest in reading and writing development among 9-12-year-old students with severe speech and physical impairment, SSPI. This article explores what five students with SSPI who have reached beyond beginner's phase without arrest in their literacy development have experienced as significant for their reading and writing…

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…

Background: More than 80% of people living with MND (plwMND) develop difficulties with their speech, affecting communication, self-identity and quality of life. Most plwMND eventually use an augmentative and alternative communication device (AAC) to communicate. Some AAC devices provide a synthesized voice for speech, however these voices are…

Children with autism spectrum disorder (ASD) who have limited speech are often taught to communicate using a speech-generating device (SGD). We evaluated procedures for teaching a mand for information (i.e., "Where" is [item]?) using an interrupted behavior chain procedure. In Experiment 1, all participants (3 children with ASD who…

Nonvocal alert patients in the intensive care unit (ICU) setting often struggle to communicate due to inaccessible or unavailable tools for augmentative and alternative communication. Innovation of a hand-operated non-touchscreen communication system for nonvocal ICU patients was guided by design concepts including speech output, simplicity, and…

Purpose: This study compared the performance of three amplification devices hypothesized to improve speech communication in individuals with hypophonia (HP), as well as to identify individuals' device preferences. Method: Twenty-two individuals with HP and their primary communication partners participated in a cross-over design study comparing…

This meta-analysis aimed to evaluate single-case studies that used high-tech speech-generating devices (SGDs) for children with autism spectrum disorders (ASD) ages 0-8. The focus of this review was to measure the effect size of high-tech SGD intervention on verbal behavior. The review included 20 studies with 54 participants with ASD. The results…

Purpose: This study seeks to determine how speech-language impairments relate to the frequency and diversity of communication modes and functions produced by children with cerebral palsy (CP) during interactions with their mothers. Method: We studied 40 children with CP (M[subscript age] = 62 months) comprising three groups--those who were unable…

The purpose of this study was to evaluate the use of an interrupted chain procedure and a time delay with full physical prompts, in the establishment of peer manding, within a naturally occurring classroom routine. The participants included three preschool aged children with autism spectrum disorder (ASD), who used a tablet-based speech-generating…

The present study investigated the effects of different types of recasts and prompts on the rate of repair and spontaneous use of novel vocabulary by eight children with severe motor speech disabilities who used speech-generating technologies to communicate. Data came from 60 transcripts of clinical sessions that were part of a conversation-based…

Communication supports for people with motor speech disorders can include strategies and technologies to supplement natural speech efforts, resolve communication breakdowns, and replace natural speech when necessary to enhance participation in all communicative contexts. This article emphasizes communication supports that can enhance…

This study aimed to teach individuals with autism spectrum disorder (ASD) and limited vocal speech to emit target vocalizations while using a speech-generating device (SGD). Of the 4 participants, 3 began emitting vocal word approximations with SGD responses after vocal instructional methods (delays, differential reinforcement, prompting) were…

Meaningfully synthesizing single case experimental data from intervention studies comprised of individuals with low incidence conditions and generating effect size estimates remains challenging. Seven effect size metrics were compared for single case design (SCD) data focused on teaching speech generating device use to individuals with…
