Potential opportunities for mid- to high-tech AAC continue to emerge, such as modifications to fit an individual’s unique needs and abilities more precisely. This adaptability allows for a wide range of communication options, from simple pre- recorded messages to more sophisticated, eye-controlled systems. 8 Furthermore, rapid advancements in technology, including in speech recognition, natural language processing, eye-tracking, and mobile devices, have improved the capabilities and accessibility of AAC devices. This means that more people who need AAC can have access to them. 9

The advent of app development presents a significant opportunity in digital AAC. As machine learning and natural-language processing come to the forefront, further research is essential to optimize AAC solutions, leveraging cutting-edge technology to improve user experience, affordability, and portability. Addressing the unmet global need for AAC requires a multi-faceted approach that includes raising awareness, improving accessibility, reducing costs, enhancing education and training, fostering research and development, and considering cultural and linguistic diversity in the provision of AAC. Collaborative efforts between governments, healthcare professionals, educators, technology developers, and advocacy groups are crucial to making meaningful progress in meeting the communication needs of individuals with speech and language disorders worldwide.
