Augmentative and alternative communication(AAC)


Augmentative and alternative communication(AAC) is an umbrella term that encompasses the communication methods used to supplement or replace speech or writing for those with impairments in the production or comprehension of spoken or written language.



AAC includes all of the ways we share our ideas and feelings without talking. We all use forms of AAC every day. You use AAC when you use facial expressions or gestures instead of talking. You use AAC when you write a note and pass it to a friend or coworker. We may not realise how often we communicate without talking.  
People with speech or language difficulties may need AAC to help them communicate. Some may use it all of the time. Others may say some words but use AAC for longer sentences or with people they don’t know well. AAC can help in school, at work, and when talking with friends and family.  

Types of AAC

Do any of your students have difficulty talking? There are options that might help. There are two main types of AAC—unaided systems and aided systems. You may use one or both types. Most people who use AAC use a combination of AAC types to communicate.  

Unaided Systems  

You do not need anything but your own body to use unaided systems. These include gestures, body language, facial expressions, and sign language.  

Aided Systems 

An aided system uses some sort of tool or device. There are two types of aided systems—basic and high-tech. A pen and paper is a basic aided system. Pointing to letters, words, or pictures on a board is a basic aided system. Touching letters or pictures on a computer screen that speaks for you is a high-tech aided system, some systems have voice output.
