QuickPic AAC: An AI-Based Application to Enable Just-in-Time Generation of Topic-Specific Displays for Persons Who Are Minimally Speaking.

As artificial intelligence (AI) makes significant headway in various arenas, the field of speech-language pathology is at the precipice of experiencing a transformative shift towards automation. This study introduces QuickPic AAC, an AI-driven application designed to generate topic-specific displays from photographs in a "just-in-time" manner. Using QuickPic AAC, this study aimed to (a) determine which of two AI algorithms (NLG-AAC and GPT-3.5) results in greater specificity of vocabulary (i.e., percentage of vocabulary kept/deleted by clinician relative to vocabulary generated by QuickPic AAC; percentage of vocabulary modified); and to (b) evaluate perceived usability of QuickPic AAC among practicing speech-language pathologists. Results revealed that the GPT-3.5 algorithm consistently resulted in greater specificity of vocabulary and that speech-language pathologists expressed high user satisfaction for the QuickPic AAC application. These results support continued study of the implementation of QuickPic AAC in clinical practice and demonstrate the possibility of utilizing topic-specific displays as just-in-time supports.

Using occupational therapy principles and practice to support independent message generation by individuals using AAC instead of facilitated communication.

Facilitated communication (FC) has been a heavily debated and documented topic across multiple disciplines, including sociology, education, psychology, pediatrics, speech-language pathology, and disability studies. Although many professionals from various disciplines and advocates have offered opinions, suggestions, and research on the topic, there has been minimal input from the occupational therapy (OT) profession. The lack of OT input is noteworthy as OTs are experts in enabling upper extremity performance and independence through a variety of training, adaptation and modification strategies, and use of external supports. Because of their professional code of ethics and a specific knowledge base, OTs are uniquely positioned to provide a host of ethical and evidence-based strategies that enable independent access to communication technology. The consideration of multiple access options is contrary to the typical facilitated encounter where facilitators exclusively choose to manipulate an upper extremity in order for letters to be selected on a display or keyboard. The purpose of this paper is threefold: (a) To offer insight into the standard of care by OTs including their ethical standards; (b) to identify varied accommodations that enable access using a feature-matching standard of care that eliminates the need for a facilitator; and (c) to highlight how to increase independent assistive technology/augmentative and alternative communication access, thus dissuading the need or use of facilitated access to letters.

Miniature Linguistic Systems for Individuals With Autism Spectrum Disorder: A Systematic Review and Meta-Analysis.

PURPOSE: Miniature linguistic systems (also known as matrix training) is a method of organizing learning targets to achieve generative learning or recombinative generalization. This systematic review is aimed at determining whether matrix training is effective for individuals with autism spectrum disorder (ASD) in terms of improving recombinative generalization for instruction-following, expressive language, play skills, and literacy skills. METHOD: A systematic review methodology was employed to limit bias in the various review stages. A multifaceted search was conducted. Potential primary studies were imported into Covidence, a systematic review software, and inclusion criteria were applied. Data were extracted regarding (a) participant characteristics, (b) matrix designs, (c) intervention methods, and (d) dependent variable. A quality appraisal using the What Works Clearinghouse (WWC) Single-Case Design Standards (Version 1.0, Pilot) was carried out. In addition to the visual analysis of the data, an effect size estimate, non-overlap of all pairs (NAP), was generated for each participant. Independent t tests and between-subjects analyses of variance were conducted to identify moderators of effectiveness. RESULTS: Twenty-six studies including 65 participants met criteria for inclusion. All included studies were single-case experimental designs. Eighteen studies received a rating of Meets Standards Without Reservations or Meets Standards With Reservations. The aggregated combined NAP scores for acquisition, recombinative generalization, and maintenance of a range of outcomes were in the high range. CONCLUSIONS: Findings suggested that matrix training is an effective teaching method for individuals with ASD for acquisition, recombinative generalization, and maintenance of a range of outcomes. Statistical analyses to identify moderators of effectiveness were insignificant. Based on the WWC Single-Case Design Standards matrix training meets criteria to be considered an evidence-based practice for individuals with ASD.

Advances in augmentative and alternative communication research for individuals with Autism spectrum disorder: moving research and practice forward.

Augmentative and alternative communication (AAC) approaches offer expressive and receptive supports for the segment of the population of individuals with autism spectrum disorder (ASD) who have little or no functional speech. The National Center for Autism Evidence and Practice (NCAEP) declared augmentative and alternative communication (AAC) interventions for individuals with autism an "evidence-based practice." Following a brief analysis of the breakdown of studies included in NCAEP by dependent variable, we introduce each of the four papers published as part of this special issue on Advances in Augmentative and Alternative Communication Research for Individuals with Autism Spectrum Disorder. In addition to elucidating the contributions and advances of each paper to the research base, including the NCAEP report, we provide a critical commentary as applicable in the hopes of stimulating and guiding further research.

Effects of Interventions Involving Speech Output Technologies on Communication Outcomes for Individuals With Developmental Disabilities: A Scoping Review.

PURPOSE: This scoping review aimed to map the literature on the effects of interventions involving speech output technologies on communication outcomes for individuals with developmental disabilities other than autism spectrum disorder. METHOD: A scoping review methodology was used to limit bias in searching, selecting, coding, and synthesizing relevant intervention studies. This involved a multifaceted search for studies conducted between 1991 and March 2021 using various electronic databases, ancestry searches, and forward citation searches from selected articles. Studies had to meet stringent inclusion criteria. Each study was summarized in terms of authors, purpose, participants, design, speech output, outcomes, effectiveness, and quality appraisal. RESULTS: Twenty-five single-case experimental design studies (88 participants) and one group design studies (62 participants) qualified for inclusion. Most of the participants had multiple diagnoses followed by a diagnosis of cerebral palsy and Down syndrome. Most studies focused on requesting behaviors and to a much lesser extent on syntactic structure and word identification. A dearth of high-quality studies was identified. CONCLUSIONS: Overall, there is a paucity of high-quality research investigating the effects of speech output technologies for children with developmental disabilities. Additionally, several directions for future research are posited. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.20468928.

Attitudes Toward and Perceived Communicative Competence of Individuals with Aphasia Using Speech-Generating Devices.

The purpose of this study was to investigate the effects of interface display and respondent group on listener attitudes toward and perceived communicative competence of persons with aphasia. The Attitudes Toward Nonspeaking Persons scale and the Communicative Competence Scale was used to measure listener attitudes and communicative competence, respectively. A 2 × 3 mixed factorial design was used. Interface display videos served as the within-subjects variable (i.e., grid and scene displays), and the respondent group served as the between-subjects variable. A total of 113 respondents (i.e., undergraduate lower-division students, undergraduate upper-division students, and family caregivers of individuals with aphasia) watched an individual with aphasia using a grid display in one video and a scene display in another video. The respondents completed the two scales. Significant main effects (p < .05) were found for interface display and respondent group. The use of scene displays had a more favorable impact on competence ratings than the use of grid displays. Family caregiver ratings were significantly (p < .05) more favorable than ratings from other groups. The Communicative Competence Scale was found to be a reliable measure of perceived communicative competence. Scene displays have the potential to enhance the perceived communicative competence of this population.

Effects of a Systematic Augmentative and Alternative Communication Intervention Using a Speech-Generating Device on Multistep Requesting and Generic Small Talk for Children With Severe Autism Spectrum Disorder.

Purpose The purpose of this study was to determine the effects of augmentative and alternative communication (AAC) intervention using a speech-generating device (SGD) on acquisition, maintenance, and generalization of multistep requesting and generic small talk in three children with severe autism spectrum disorder (ASD) between the ages of 7 and 13 years. Method A multiple-baseline design across participants combined with a posttreatment multiple-generalization-probe design was used to assess acquisition, generalization, and maintenance of target communicative behaviors with the experimenter and the participants' familiar communication partners (FCPs). Intervention was composed of systematic instruction in the use of an SGD using least-to-most prompting, constant time delay, error correction, and reinforcement. Results Visual analysis established a strong functional relationship between the independent variable and the two dependent variables (i.e., requesting preferred activities, engaging in generic small talk) for all three participants. Effect size indicator analyses corroborated these findings, indicating strong effects for performing multistep requesting and medium effects for engaging in generic small talk. All participants were able to generalize the acquired communicative behaviors to request new and untrained snacks and activities and engage in generic small talk with FCPs who were not part of the training. Maintenance of acquired communicative behaviors was demonstrated 3 weeks post completion of intervention. Conclusion This study provides preliminary evidence that AAC intervention using an SGD and incorporating least-to-most prompting, constant time delay, error correction, and reinforcement is effective in terms of multistep requesting and generic small talk behaviors in children with severe ASD.

The effect of cue type on directive-following in children with moderate to severe autism spectrum disorder.

For this study, 11 children with moderate to severe autism spectrum disorder (ASD) were given directives containing prepositions in three cue conditions: (a) spoken alone, (b) a short video clip along with spoken cues, and (c) a sequence of three graphic symbols accompanied by spoken cues. Participants followed directives significantly more accurately with the video clip than with spoken cues only, and significantly more accurately with spoken cues only relative to the sequence of graphic symbols. Results suggest that the short video clip along with spoken cues may be an optimal mode for enhancing learners' ability to follow directives containing prepositions. In addition, results reveal three statistically significant correlations between participants' preexisting skills and directive-following accuracy: a positive correlation between spoken preposition preassessment total score and accuracy in the spoken-alone condition; a positive correlation between spoken noun preassessment total score and accuracy in the video-clip condition; and a positive correlation between ASD severity and the need for repetition in the video-clip condition. Results also suggested that, for children with more severe ASD symptoms, the video clips require repetitions so that the relationships illustrated within it can gain more semantic salience. Implications for clinical practice and future research are discussed.

The effects of augmentative and alternative communication interventions on the receptive language skills of children with developmental disabilities: A scoping review.

PURPOSE: To map and synthesise research evidence of the effects that aided and unaided AAC interventions have on the receptive language of children with developmental disabilities. METHOD: This scoping review used a four-pronged search strategy (electronic databases, dissertations and theses, hand search, ancestry searches) to identify germane studies. A total of 16 studies met the inclusion criteria. These studies were described in terms of the number of participants, participant characteristics, research design, AAC interventions, intervention outcomes, intervention effects, and quality appraisal. RESULT: The review revealed positive associations between aided and unaided AAC, vocabulary acquisition and symbol comprehension. CONCLUSION: AAC interventions may have merit for the development of receptive language skills in children with developmental disabilities. Specific gaps in relation to unaided AAC, aided augmented input strategies, morphological and syntax development, and discourse comprehension are highlighted.

Providing visual directives via a smart watch to a student with Autism Spectrum Disorder: an intervention note.

Smart watches are discreet and wearable tools that may be repurposed to improve directive-following for individuals with autism spectrum disorder (ASD). Specifically, a mentor can transmit just-in-time (JIT) visual supports (e.g., video clips, photographs, text) that depict an upcoming directive to a learner's smart watch to prompt the learner as needed from a distance. Using a single-case multiple probe design across settings, this investigation evaluated the effectiveness of providing text-based prompts on an Apple Watch 1 to a child with ASD within a school setting. A mentor transmitted 2-step written directives via text message to the participant's Apple Watch. The participant was instructed to attend to, read, and follow directives received on the watch. Results demonstrated that the intervention improved directive-following as well as increased the instructor's distance from the learner. It is proposed that JIT supports sent to a learner's smart watch may reduce the obtrusiveness of traditional prompting while also maintaining the naturalness of ongoing social or academic interactions. Clinical limitations and implications are discussed.
