Augmentative
and alternative communication (AAC) strategies assist people with complex
communication needs to participate more fully in their social roles including
interpersonal interaction, learning, education, community activities,
employment, volunteerism, care management, etc.
An
individual makes use of a collection of AAC strategies to meet his or her
individual requirements in a full range of communicative situations. This
collection is referred to as the person’s AAC SYSTEM. Individuals typically
draw from a range of tools and strategies to fit the particular communicative
opportunity. These may include: speech; vocalizations; speech-generating
devices; computers; tablets; cell phones; pen and paper; communication books,
wallets or boards; sign language; gestures; facial expressions; and eye gaze,
among others
For
example, an individual may use a sophisticated speech-generating system in a
classroom or work place to participate in discussion, and then use a
communication book to chat with friends. She may use her speech and/or word
approximations with familiar communication partners in combination with
gestures and eye-pointing and facial expressions. In a noisy restaurant or bar,
she may use gestures, and speech, along with typing on a smaller, more portable
AAC device. In the swimming pool, her system may be printed on waterproof paper
or laminated. During a job interview, she may have created answers to common
questions and stored them in her communication device, to facilitate her
response speed, but also have access to the rest of her vocabulary so she can
generate exactly what she wants to say, as needed. At home on her computer,
chatting with friends or emailing, she may use a variety of different access
methods that function as the keyboard and mouse on her computer.
