Augmentative and Alternative Communication (AAC): An Introduction

What is AAC?

AAC stands for Augmentative and Alternative Communication.
Augmentative means to supplement or add to existing skills. 

Alternative means to use something different.

Therefore, AAC is used to describe various methods of communication that can add to or replace speech in individuals who have no or limited verbal communication.

Types of AAC

AAC can be both ‘unaided’ and ‘aided’.

  • Unaided AAC is communication methods which only require use of the body e.g. body language, facial expression, getsure, eye pointing and sign language

  • Aided AAC is communication methods which use tools or materials

Aided AAC can be further categorised into low tech/ paper based and high tech 

  • Low tech/ paper based AAC is using communication methods such as symbol boards, Picture Exchange Communication System (PECs), communication books and alphabet charts

  • High Tech AAC is using a speech generating device. This may be a device purely for the purpose of communication (e.g. an Accent 1000), or it may be an app on a tablet or smartphone

Why use AAC?

Many children diagnosed with Autism are unable to verbally communicate their wants, needs and thoughts. When a child is unable to communicate, it can affect many aspects of their life including access to education, social relationships and behavioural difficulties due to the frustration of being unable to communicate effectively. Communication is a right which should be granted to every individual, regardless of their language learning abilities. AAC has many benefits for people who struggle to learn language. It can help support language learning, it can build stronger relationships with others and it can increase independence and decision making.
