Augmentative and Alternative Communication (AAC)

Augmentative and alternative communication (AAC) refers to a range of methods and strategies to support verbal language (speech). These may include simple systems such as gesture and pointing or high-tech devises, such as computer technologies.

AAC may include:

• Natural gesture and body language (e.g. pointing, eye gaze, facial expression)

• Signing

• Objects of reference (objects relating to daily routines and activities)

• Alphabet or word boards

• Choosing boards

• Talking mats

• Communication books with photos/symbols

• Visual timetables and schedules

• PECS (Picture Exchange Communication System)

• Voice Output Communication Aids (VOCAs)

• Switches (buttons which when pressed play a pre-recorded message and/or activate a toy)

• Tablets and computer technologies

• Eye gaze technology

AAC is introduced to support the communication of those who cannot effectively communicate through verbal means. This may be a temporary support or long-term solution and AAC approaches should be considered on an individual basis. It is important to note that AAC is rarely, if ever, introduced as a replacement for speech, but a supportive strategy to aid effective communication.

When working with young children I mostly adopt a ‘total communication’ approach. This involves introducing a range of the above strategies to support a child’s attention and listening, understanding and expressive communication.
