Definition of: AAC

(Advanced Audio Coding) An audio compression technology that … provides greater compression and better sound quality than MP3

Augmentative and Alternative Communication (ASHA, 2005)

refers "to an area of research, clinical, and educational practice.

AAC involves attempts to study and when necessary compensate for temporary or permanent impairments, activity limitations, and participation restrictions of individuals with severe disorders of speech-language production and/or comprehension, including spoken and written modes of communication"

Augmentative and Alternative Communication (ASHA, 1991)

5

An integrated group of components, including the symbols, aids, strategies and techniques used by individuals to enhance communication.

Symbols

refer to the methods used for visual, auditory, and/or tactile representation of conventional concepts gestures manual sign sets/systems printed words objects spoken words Braille pictures/photographs

Aids

refer to physical objects or devices used to transmit or receive messages a communication book, board, chart, electronic device, or computer

Strategies

8

refer to ways of using AAC aids, symbols, and/or techniques more effectively for enhanced communication.

a strategy… is a plan that can facilitate one's performance.

It is an integrated network of techniques, aids, strategies, and skills that a person uses to communicate.

AAC incorporates the individual's full communication abilities (multimodal), which may include: speech and other vocalizations, facial and manual gestures, as well as specific strategies and skills for using these

various modes successfully in a variety of communication contexts

An aid is not a communication system, but rather one component of an individual's communication overall system

The use of special devices and methods of communication enhances or provides alternatives for spoken language.

The use and needs of AAC systems may change over time...

Augmentative and Alternative Communication (Lewis, 1993)

04/19/23AAC

15

AAC: A set of approaches that is used to improve the communication skills of a person who does not speak or whose speech is not intelligible.

Augmentative Communication Approaches are used to supplement, enhance or support the communication processes for persons who have some speaking skills.

Alternative Approaches replace speech as a means of communication.
