Augmentative and alternative communication (AAC) includes communication strategies, techniques and aids used by people who are unable to speak, or use speech as their primary method of communication. While interactions between people with and without disability are often wrought with misperceptions, communication difficulties create another layer to uncover the person. The purpose of this study was threefold: (1) to employ the expertise of people who use AAC in order to gain a better understanding of their communication experience; (2) to better understand the factors which impact interactions; and (3) to understand the relationships among these factors. Qualitative research methods were used to analyze the content of first-person narratives of adults with lifelong disability who use AAC, describing the communication experiences, obstacles and strategies for success.

Analysis revealed a multitude of factors which contribute to participation and success. The overriding theme was that communication is the key to participation in the major activities of life. However, there are many obstacles to communication for people who use AAC which require advocacy, education and consequent changes in social perceptions and the opportunities afforded people who rely on AAC. At a global level, these finding call upon the AAC field to acknowledge that there are aspects of the communication experience unknown to most professionals. Acceptance of this actuality has specific implication for research, clinical practice and the education of current and future professionals. In addition, the identification of interrelated factors contributing to communicative interactions at multiple levels supports a multi-faceted practice model for service providers in the field of AAC. It is only by incorporating the knowledge of AAC users to break down the barriers to interactions at every level that each individual who relies on AAC will have the opportunity to participate in all aspects of life.
