This article highlights the external barriers that may impact the language learning of people who need or use augmentative and alternative communication (AAC) including barriers related to AAC tools. It identifies opportunities and priorities for future research and technology development to reduce these barriers and better support language learning. Examples of ACC tools are gestures, body language, manual signs, communication boards with graphic symbols and mobile technologies
The paper integrates the lived experiences of individuals who need or use AAC and their families with key research findings to highlight external challenges that may negatively impact language learning such as:
- delays in access to AAC
- service providers’ limited competencies in AAC
- the lack of fit between AAC systems and user needs and strengths
- limited opportunities for social interaction
- communication partners with limited experience and training in AAC.
Future research, technology development and policy change are required to reduce the barriers. The paper recommends people who need or use AAC and their families must be involved as equitable partners in this work to ensure that it addresses their most pressing needs and results in meaningful and valued outcomes.
