Alternative Augmentative Communication in paediatric dentistry: a mighty tool to amplify mother tongue's power.

AIM: The role of a child's mother tongue in shaping his/her identity and emotional development is crucial. In the context of paediatric dentistry, this principle should always be reminded. The child's right to effective communication, even when a language barrier exists, is a fundamental principle, as recently stated in the 'Rights from the Start' rights fact sheet. Preserving a child's native language in the dental setting, especially in the context of an increasingly diverse society with a significant number of refugee children, is essential. Augmentative and Alternative Communication (AAC) strategies can assist in bridging language gaps and improving treatment outcomes, blending with the traditional approaches used in paediatric dentistry. The article promotes flexibility, innovation, and empathy in paediatric dentistry to provide optimal care and ensure that every child's rights are respected. CONCLUSION: • The relationship with one's mother language plays a central role in children's growth and in the relationship they can develop with the world, "motherised" by the words of the caregiver. • The interaction between immigrant children from different linguistic and cultural backgrounds and dentists providing their care requires the integration of traditional paediatric dental techniques with AAC strategies that can compensate for deficient oral communication. • Dentists treating immigrant children should follow the suggestions proposed in this article to establish the best and most tailored paediatric setting for the child's specific needs.

A Randomized Controlled Trial Comparing Face-to-Face Versus Remote Delivery of Low-Tech Augmentative and Alternative Communication in Nonspeaking Children With Autism Spectrum Disorder.

PURPOSE: Thirty percent of children diagnosed with autism spectrum disorder (ASD) do not develop spoken language. To provide a means of communication for this subset of the population, augmentative and alternative communication (AAC) systems are often utilized. Low-tech options have traditionally been delivered through the in-person modality. However, due to the COVID-19 pandemic, changes to service delivery models have been required. This randomized controlled trial was conducted in order to assess the efficacy of low-tech AAC delivered face-to-face versus remotely on communication outcomes in nonspeaking children with ASD. CONCLUSIONS: Both participant groups demonstrated similar gains in AAC proficiency, number and type of nonspeaking acts, and number of spoken communication acts. Remote delivery of low-tech AAC treatment is a viable alternative to face-to-face instruction.

Still having his say: David Yoder's legacy in AAC.

On February 2 2023, one of the guiding lights in the field of augmentative and alternative communication (AAC) for more than four decades, David E. Yoder, passed away at the age of 90. A voracious reader and gifted storyteller, David was particularly fond of a quote from George Bernard Shaw's Back to Methuselah, "You see things; and you say 'Why?' but I dream things that never were; and I say 'Why not?'" That vision led him to take on multiple leadership roles and influence the field of AAC in multiple ways. He played a pivotal role in establishing both the International Society for Augmentative and Alternative Communication (ISAAC) and the United States Society for Augmentative and Alternative Communication (USSAAC). Additionally, he chaired the panel for the National Institute on Disability and Rehabilitation Research (NIDRR)'s inaugural Consensus Validation Conference on AAC, advocated for the American Speech-Language-Hearing Association to recognize AAC within the profession's scope of practice, and served as the first editor for the Augmentative and Alternative Communication journal. In this tribute, we describe David's diverse and unique contributions to improving the lives of people with communication challenges with a focus on some of his central insights and actions.

Project Building Bridges: A Framework for Preparing Highly Qualified Speech-Language Pathologists to Serve Culturally and Linguistically Diverse Students With Augmentative and Alternative Communication Needs.

PURPOSE: Project Building Bridges was funded by the U.S. Department of Education Office of Special Education Programs to address the shortage of speech-language pathologists qualified to serve students with complex communication needs who benefit from augmentative and alternative communication (AAC) and are culturally and linguistically diverse. The purpose was to train future speech-language pathologists in culturally responsive AAC practices through coursework and fieldwork in AAC integrated into the Master of Science degree in Speech, Language and Hearing Sciences. METHOD: Fifty-seven graduate students completed the project. The scholars' curriculum consisted of two AAC courses, both on-campus and externship AAC clinical practicum experiences to provide services to multicultural and linguistically diverse students, a U.S. or international service-learning opportunity, and cumulative portfolio presentations. RESULTS: Mixed-methods outcome measures consisted of four sets of pre- and postsurveys and qualitative feedback from exit interviews to assess changes in graduate student competencies. Significant differences were demonstrated between scholars' pre- and post-assessments of confidence ratings. Significant differences were also demonstrated in both scholars' and school mentors' pre- and post-assessments of competency ratings. No significant differences were found between evaluations of AAC preparation by Clinical Fellowship (CF) candidates and their CF mentors at 1 year postgraduation. CONCLUSIONS: Project Building Bridges provides a framework for preparing highly qualified speech-language pathologists to serve culturally and linguistically diverse students who benefit from AAC as evidenced by pre- and postsurvey results. The project can serve as a model for other university programs in the development of preservice preparation programs focusing on culturally and linguistically diverse students with AAC needs.

A systematic review of acquisition and mastery of skills taught using the Picture Exchange Communication System.

The Picture Exchange Communication System (PECS) is a popular augmentative and alternative communication intervention for individuals with developmental disabilities that includes six, sequential phases of instruction. We systematically reviewed published and unpublished single-case PECS studies for details about the percentage of participants mastering PECS phases, how long it took participants to master PECS phases (in trials to mastery), and what constituted mastery of PECS phases. We found most participants mastered only the first two phases of PECS, and Phases I, II, and IV showed the slowest and widest variability in trials to mastery. Moreover, participants who were taught the third PECS phase learned to select from an average array of three symbols, which may limit the range of messages they can communicate. We discuss our findings in light of a few important limitations and provide directions for future researchers along with recommendations for professionals who might consider PECS.

A Comprehensive Scoping Review of Caregivers' Experiences With Augmentative and Alternative Communication and Their Collaboration With School Professionals.

PURPOSE: Parent engagement and involvement is essential for the successful implementation of augmentative and alternative communication (AAC) systems in the home. The purpose of the current study is to gain a deeper understanding of caregivers' experiences with AAC systems and their collaboration with school professionals during the implementation of AAC, which may have led to subsequent abandonment. METHOD: This review intentionally included qualitative studies that employed semistructured interviews, focus groups, and ethnographic investigations that documented the experiences and perceptions of families implementing AAC at home. Electronic database search, ancestral search, and forward search procedures resulted in a total of 27 peer-reviewed studies portraying the voices of 319 caregivers. RESULTS: An inductive analysis was conducted to record recurring themes into codes. The codes were thematically synthesized into three main themes: (a) the family unit, (b) the service providers, and (c) the AAC system. CONCLUSIONS: The results emphasized the need for participatory practices of family involvement in co-constructing a collaborative AAC service provision. Future research directions should implement this practice and explore the outcomes of this process to validate its efficacy.

Parents' Perceptions of Eye-Gaze Technology Use by Children With Complex Communication Needs.

PURPOSE: Some preschool students with complex communication needs explore eye-gaze computer technology (EGCT) and adopt computer-based augmentative and alternative communication (AAC). The objective of this study was to follow preschool explorers of EGCT who are now school aged to describe the children's use of technology and parents' perceptions of its utility for communication, participation, or leisure. METHOD: Ten parents completed survey questions by Internet and phone and reported their perceptions of nine children's effectiveness in the use and acceptance of AAC and the support they received in implementing technology. The results are reported as a descriptive study. RESULTS: All children in this research continue to use AAC technology in school and most at home. Many children who tried and obtained EGCT while in preschool continue to use that technology. Most parents agreed that the children understood how to use the devices, which enhanced the children's communication, and that the parents received sufficient support. Most children were limited in their use of the devices for leisure and control of their environments. CONCLUSIONS: Computer-based AAC for school-aged children who trialed it when they were in preschool appears to be a powerful means for them to communicate and participate. However, the technology appears not to be used to its full capabilities to support the children's agency to control environments and to pursue leisure. Teams may want to consider how to support children in using their AAC devices to meet multiple needs. The study was limited by its small sample size and its descriptive nature. Additional research on this subject is needed.

Modality Synchronization When People With Aphasia Read With Text-to-Speech Support.

PURPOSE: Text-to-speech (TTS) technology potentially benefits people with aphasia by presenting content through two modalities simultaneously; however, for this to help, eye fixations must synchronize with the auditory rendition of words. Researchers have yet to explore how often and to what extent people with aphasia achieve modality synchronization. This retrospective analysis examined the percent of words people with aphasia see and hear concurrently when reading passages presented via TTS technology. Text-to-speech (TTS) technology potentially benefits people with aphasia by presenting content through two modalities simultaneously; however, for this to help, eye fixations must synchronize with the auditory rendition of words. Researchers have yet to explore how often and to what extent people with aphasia achieve modality synchronization. This retrospective analysis examined the percent of words people with aphasia see and hear concurrently when reading passages presented via TTS technology. METHOD: Nine adults with aphasia had their eye movements tracked while processing TTS passages at a preselected default rate of 150 words per minute. Modality synchronization occurred whenever fixation on a written word occurred during the time span beginning 300 ms before auditory presentation and ending at the next word's initiation. Correlations between standardized test scores, unsupported reading rate, and modality synchronization percentages were informative about the association of aphasia and reading impairment severity with achievement of synchronicity. RESULTS: Three participants demonstrated consistent modality synchronization; average synchronicity ranged from 67% to 76% of passage words. One participant displayed inconsistent synchronization within passages and achieved an average of 58%. The remaining five participants rarely achieved synchronization, with fixations typically lagging substantially behind the auditory presentation. A significant positive correlation occurred between paragraph reading comprehension test scores and modality synchronization percentages. CONCLUSIONS: A default TTS presentation rate does not result in dual modality synchronization for most people with aphasia. This lack of synchronization may contribute to inconsistencies in the benefit people with aphasia experience when provided with TTS support.

Leveraging Communication Partner Speech to Automate Augmented Input for Children on the Autism Spectrum Who Are Minimally Verbal: Prototype Development and Preliminary Efficacy Investigation.

PURPOSE: Augmentative and alternative communication (AAC) technology innovation is urgently needed to improve outcomes for children on the autism spectrum who are minimally verbal. One potential technology innovation is applying artificial intelligence (AI) to automate strategies such as augmented input to increase language learning opportunities while mitigating communication partner time and learning barriers. Innovation in AAC research and design methodology is also needed to empirically explore this and other applications of AI to AAC. The purpose of this report was to describe (a) the development of an AAC prototype using a design methodology new to AAC research and (b) a preliminary investigation of the efficacy of this potential new AAC capability. METHOD: The prototype was developed using a Wizard-of-Oz prototyping approach that allows for initial exploration of a new technology capability without the time and effort required for full-scale development. The preliminary investigation with three children on the autism spectrum who were minimally verbal used an adapted alternating treatment design to compare the effects of a Wizard-of-Oz prototype that provided automated augmented input (i.e., pairing color photos with speech) to a standard topic display (i.e., a grid display with line drawings) on visual attention, linguistic participation, and (for one participant) word learning during a circle activity. RESULTS: Preliminary investigation results were variable, but overall participants increased visual attention and linguistic participation when using the prototype. CONCLUSIONS: Wizard-of-Oz prototyping could be a valuable approach to spur much needed innovation in AAC. Further research into efficacy, reliability, validity, and attitudes is required to more comprehensively evaluate the use of AI to automate augmented input in AAC.

Examining core vocabulary with language development for early symbolic communicators.

PURPOSE: Core vocabulary lists are frequently used to select vocabulary for early symbolic communicators who require augmentative and alternative communication (AAC). The current study extended existing work by investigating how core vocabulary lists overlap and diverge from typical language development. METHOD: We investigated when the words on seven core vocabulary lists emerge in typical language development, the composition of the lists based on their parts of speech, and how the composition of the words on the lists compare to the MacArthur Bates Communication Development Inventories (CDI). RESULT: On average, the words on the seven core vocabulary lists appear after the second year of life in children with typical spoken language development (25, 27, 37, 45, 47, 50, and 66 months). Verbs were the most prevalent part of speech in all but one of the core vocabulary lists. Core vocabulary words made up only a small percentage of words on the CDI. CONCLUSION: The words on the core vocabulary lists do not emerge until later points in typical lexical development. Focussing on core words when working with early symbolic communicators who require AAC may lead to limited and variable lexicons with wide gaps.

Developing Augmentative and Alternative Communication Competence in Preservice Speech-Language Pathologists: A Collaborative Model for Clinical Educators.

PURPOSE: Practicing speech-language pathologists (SLPs) reveal a perceived lack of preparedness to deliver augmentative and alternative communication (AAC) services. This is concerning because it is indicative of inadequate graduate training in AAC. The purpose of this clinical focus article was to present a collaborative model of clinical education for AAC preservice training. This clinical focus article will provide recommendations to support practicing SLPs in the provision of effective clinical instruction for preservice clinicians working with individuals with complex communication needs who require AAC. METHOD: There is an urgent need for improved training for clinical educators providing instruction in AAC. In this clinical focus article, a literature review of the existing evidence regarding best practices in clinical education and AAC training for SLPs was completed to explore current theoretical and practical approaches. The evidence was utilized to create a collaborative model of recommended clinical education in AAC. RESULTS: There is limited guidance for clinical educators when it comes to training preservice clinicians. This clinical focus article provides recommendations for AAC training of preservice SLPs by clinical educators in the field of speech-language pathology. CONCLUSIONS: The collaborative model proposed in this clinical focus article delivers a roadmap to guide practicing SLPs in the development of AAC clinical competence of preservice clinicians. Future research is needed to evaluate the effectiveness of the model.

A retrospective chart review of the patient population accessing augmentative & alternative communication at an urban assistive technology center.

The purpose of this study was to 1) identify and describe the population seeking alternative and augmentative communication (AAC) evaluations at an assistive technology (AT) center in the Midwestern United States and 2) describe the AAC device features or services participants identify as most important at their initial AAC evaluations. Charts of 53 participants seeking AAC interventions at an AT center in the Midwestern United States were retrospectively reviewed. Information from the QUEST 2.0 was used to determine what AT features were identified as most important. The majority of participants seen at the AT center had progressive diseases. Across all of the participants, ease of use and effectiveness were identified as the "most important" aspects of an AAC device satisfaction. These findings highlight the importance of determining who is accessing AAC services across AT centers to determine whether barriers to AAC services exist. Moreover, patients report regarding what variables they deem as most important reflect the fact that excellent service-delivery may not overcome the importance of other variables, such as ease of use that impact AAC use.

A large-scale comparison of two voice synthesis techniques on intelligibility, naturalness, preferences, and attitudes toward voices banked by individuals with amyotrophic lateral sclerosis.

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 should ideally sound uniquely like the individual's natural speech, be intelligible, and elicit positive reactions from communication partners. This large-scale 2 x 2 mixed between- and within-participants design examined perceptions of 831 adult listeners regarding custom synthetic voices created for two individuals diagnosed with ALS via two synthesis systems in common clinical use (waveform concatenation and statistical parametric synthesis). The study explored relationships among synthesis system, dysarthria severity, synthetic speech intelligibility, naturalness, and preferences, and also provided a preliminary examination of attitudes regarding the custom synthetic voices. Synthetic voices generated via statistical parametric synthesis trained on deep neural networks were more intelligible, natural, and preferred than voices produced via waveform concatenation, and were associated with more positive attitudes. The custom synthetic voice created from moderately dysarthric speech was more intelligible than the voice created from mildly dysarthric speech. Clinical implications and factors that may have contributed to the relative intelligibilities are discussed.

Parental perceptions of social life before and after attending a parent training program for children with complex communication needs: the ComAlong example.

Parent training programs aimed at improving language outcomes for children with complex communication needs have predominantly been evaluated on child-centered outcomes and less often on the impact on social life or parental well-being. This study examined parent perceptions of social life before and after ComAlong, a group intervention providing parents with knowledge and training in responsive communication, environmental-milieu teaching strategies and augmentative and alternative communication (AAC). Parents (N = 467) completed questionnaires during the first and last sessions of ComAlong groups held in Sweden 2012 to 2018. Main outcome measure was change in the Social Life Scale from the Family Impact Questionnaire. Associations between this measure and demographic factors of parents and children were analyzed, along with reported change in parents' use of AAC. Pre-post comparisons revealed small significant positive changes in perceived impact of social life following intervention. The magnitude of the positive change was larger among parents of children with non-syndromic diagnoses and parents of children with autism spectrum disorder or attention deficit hyper activity disorder (ADHD). Differences in social life impact was not associated with parents' gender, language proficiency, age, or educational background. In conclusion, communication-focused parent training programs can have a positive impact on social family life and may thereby influence children's participation.

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.

Is there a 'universal' core? Using semantic primes to select vocabulary across languages in AAC.

Core vocabulary lists and vocabulary inventories vary according to language. Lists from one language cannot and should not be assumed to be translatable, as words represent language-specific concepts and grammar. In this manuscript, we (a) present the results of a vocabulary overlap analysis between different published core vocabulary lists in English, Korean, Spanish, and Sepedi; (b) discuss the concept of universal semantic primes as a set of universal concepts that are posited to be language-independent; and (c) provide a list of common words shared across all four languages as exemplars of their semantic primes. The resulting common core words and their corresponding semantic primes can assist families and professionals in thinking about the initial steps in the development of AAC systems for their bilingual/multilingual clients.

Turn-taking and communication modes of students and staff in group activities at non-inclusive schools for students with intellectual disability.

Most students with intellectual and communicative disability who rely on augmentative and alternative communication (AAC) attend non-inclusive school settings. Little is known about turn-taking and the use of various communication modes in groups of students and staff in this context. Previous studies on single students with intellectual disability in various school settings have found that staff tend to dominate interactions and augmented communication modes are used more during structured than unstructured activities. The present study explored turn-taking contributions and communication modes in whole groups of students and staff in non-inclusive school settings in Sweden. Video observations of 33 students and 30 school staff were conducted in seven classrooms during one structured activity (circle time) and one unstructured activity (leisure time). Turn-taking contributions and communication modes were examined when comparing students and staff and when comparing the two activities. Findings revealed that staff dominated the interactions and augmented communication modes were used less during leisure time than circle time. Notably, aided augmented communication modes, particularly speech-output technologies, were used sparsely. Findings of this study highlight the importance of supporting staff members in applying partner strategies and incorporating augmented input, especially aided augmented input, across various group activities at school.

Design of aided augmentative and alternative communication systems for children with vision impairment: psychoacoustic perspectives.

Children with complex communication needs often have multiple disabilities including visual impairments that impact their ability to interact with aided augmentative and alternative communication (AAC) systems. Just as the field benefited from a consideration of visual cognitive neuroscience in construction of visual displays, an exploration of psychoacoustics can potentially assist in maximizing the possibilities within AAC systems when the visual channel is either (a) not the primary sensory mode, or (b) is one that can be augmented to ultimately benefit AAC outcomes. The purpose of this paper is to highlight background information about psychoacoustics and present possible future directions for the design of aided AAC system technologies for children with visual impairments who rely on auditory information to learn and utilize AAC.

Determining an Effective Language Sample Elicitation Strategy for Early Language Learners Who Speak Using Augmentative and Alternative Communication.

PURPOSE: This study evaluates three different language sample elicitation strategies to determine a valid elicitation strategy for early language learners who speak using augmentative and alternative communication (AAC). METHOD: Ten children who speak using AAC participated in this study. Language samples were elicited from each participant using three strategies: the Communication and Symbolic Behavior Scales (CSBS), a generic play-based elicitation strategy, and automatic data logging. Samples were transcribed and coded. Additionally, each participant's school speech-language pathologist completed a Communication Matrix. Data from coded language samples were correlated with Communication Matrix results to determine the elicitation strategy that yielded the most valid language sample in comparison to Communication Matrix results. RESULTS: Both the CSBS and the play-based strategy yielded clinically relevant information. Because the log lacked communicative context, resulting data from the log was limited. An analysis of variance revealed significant differences in the amount of information elicited from each elicitation strategy. The CSBS repeatedly elicited the most data, followed by the play-based strategy and then the log. Generic play-based strategy results yielded the most correlations with Communication Matrix data. CONCLUSIONS: This preliminary data suggest that the play-based elicitation strategy elicited the most valid language sample when compared to the Communication Matrix from early language learners who speak using AAC. Additionally, results suggest that the CSBS may be an effective tool to measure the limits of this population's expressive language abilities.

Emergency and Disaster Preparedness for Individuals Who Use Augmentative and Alternative Communication: A Pilot Study on Supported Planning Using a Toolkit.

PURPOSE: When emergencies or disasters arise, individuals who use augmentative and alternative communication (AAC) are particularly vulnerable. It is critical that individuals who use AAC are supported to make decisions that impact their own lives and are able to communicate during such a crisis. Preparedness efforts that include a plan around communication needs and supports are necessary for ensuring that individuals who use AAC are able to understand options that ensure personal safety and express their needs during a time of crisis. METHOD: Qualitative methods were used to identify and describe the experiences of two young adults who use AAC and their caregivers when engaging in person-centered planning intervention sessions to complete the activities of the United States Society for Augmentative and Alternative Communication (USSAAC) emergency/disaster preparedness toolkit. Pre-intervention interviews and subjective, objective, assessment, and plan (SOAP) notes taken after each intervention session were done to describe their preparedness and experiences completing the toolkit. Themes were identified to describe participant experiences and change in their perceived preparedness. RESULTS: Five themes and 18 subthemes emerged from the pre-intervention interviews and the SOAP notes across 14 intervention sessions that captured each participant and their caregiver's awareness of needs, barriers in emergency situations, challenges in completing the toolkit, and actions during person-centered planning with the toolkit (e.g., personalizing communication boards, making a go bag, and scheduling visits with local emergency agencies). CONCLUSIONS: This study highlights the need for preparedness activities that are person-centered and account for the communication support needs of individuals who use AAC if faced with an emergency/disaster. Outcomes suggest that these methods were feasible and supported positive change in perceived preparedness in the young adults who used AAC and their caregivers.
