What is AAC?

There are many methods to communicate and they are all valid. AAC stands for Alternative, Augmentative Communication. We all use different methodologies of communication in one form or another every single day.

Multi-modal Communication

Communicating using more than one method can be called “Multi- modal communication.” We all use multi-modal communication everyday.

Multimodal communication means that an individual will utilise multiple ways to communicate their wants, needs and ideas. Communicators may utilise:

• Vocalisations
• Environmental noises
• Word approximations
• Gestures
• Sign Language
• Pointing
• Low Tech AAC
• High Tech AAC

Augmentative Alternative Communication (AAC)

AAC is an alternative form of communication to the spoken word. It supports individuals to communicate and access the world around them more fully. It is valid communication and must always be respected in all its forms.

All individuals can and do access AAC in various formats. Often AAC is a chosen methodology of communication by non-speaking individuals. There is no minimum age requirement to access AAC.

AAC is a valid communication methodology that can support communication development by:

• Scaffolding language development
• Supporting communicators to “see” language
• Supporting communicators to “hear” language

AAC Communication Systems

There are two types of AAC Communication Systems; Aided and Unaided.

Unaided AAC Communication Systems

Unaided Communication relies solely on non-verbal methods of communication. 

These systems may include:

• Facial expression
• Gesture
• Body language
• Sign language

Unaided modes of modes of communication often require adequate motor control and communication partners who can interpret the intended message.

There are two types of AAC Communication Systems; Aided and Unaided. Aided Communication relies on some external support in addition to the users body. Unaided Communication relies solely on non-verbal methods of communication. 

Aided AAC Communication Systems

Aided Communication relies on an external support in addition to the users body.

• Communication boards with symbols (e.g., objects, pictures, photographs, line drawings, visual-graphic symbols, printed words, traditional orthography)
• Computers
• Handheld devices
• Tablet devices

No Prerequisite

AAC is an accessible communication for all individuals.

It will not inhibit Speech

Alternative Augmentative Communication will not inhibit verbal communication. It will support and scaffold communication development.
