Given the linguistic and cognitive demands of communication, adult Augmentative and Alternative Communication (AAC) users with acquired communication disorders may have difficulty using AAC systems consistently and effectively in "real-life" situations. The process of recommending AAC systems and strategies is an area of exploration, where clinicians need to treat each client as a unique individual. Speech-language pathologists are required to analyze speech, language, cognition, sensory, and motor skills of the client when attempting to choose appropriate AAC systems. Various challenges during the AAC implementation process may range from funding sources, time commitment, training, and device acquisition to effective use of the device in day-to-day situations. The AAC management strategies are discussed in light of functional and multimodal communications. Also, the perspectives of AAC user regarding environment, communication partners, social communication status, and quality of life are addressed, along with a brief case report highlighting challenges and successes with AAC systems.
