Augmentative and alternative communication (AAC)
Augmentative and Alternative Communication (AAC) is a key focus area for the speech pathology department of Novita Children's Services. Some children may not develop sufficient speech to communicate well and therefore require some form of AAC Novita speech pathologists work with children, their families and other team members to design the best possible communication system for each child and their family, helping children to reach their full potential.

AAC stands for augmentative and alternative communication:
Therefore AAC is the term used for all communication that is not speech, but is used to enhance or to replace speech. An AAC System means the whole combination of methods used for communication, for example, gestures, eye pointing, vocalizations and pointing to symbols.

AAC systems can help people who cannot speak to:
-
communicate (our most powerful skill) - "If all of my possessions were taken from me with one exception, I would choose to keep the power of communication, for by it I would regain all the rest" [Webster, Daniel. Politician & orator (1782 1852]
-
develop language skills
-
decrease frustration
-
increase socialisation - "To me and others like me, being able to communicate puts us in society. It lets us have a voice. For me, having a Liberator (voice output device) has changed my life completely." [McFadden (1995) - refer to the CALL Centre Education link in the Related External Links list on this page]
-
increase participation
-
have control over what happens to them.
AAC might be suggested:
-
if speech is slow to develop
-
as a back-up if speech is difficult to understand
-
as a way of communicating most of the time if speech ability is very limited or non-existent
-
to help develop understanding of delayed language.
An AAC system may be either a short or a long-term solution to communication difficulties being experienced by a child.

"Children will use the quickest, most effective, and most accessible way available to them to communicate. Speech beats any other AAC system if it is available to the child. Since AAC includes all communication methods, intervention also addresses improving functional verbal skills. Available research indicates that AAC facilitates spoken language by increasing interaction, language skills, and/or providing a voice output model for speech." (Cynthia J, Cress PhD)

For all people, the type of communication needed throughout each day varies greatly. For example:
-
we talk with a variety of people, such as friends, strangers, superiors, relatives
-
we talk in a variety of places, such as:
-
a noisy place, such as at the football
-
a dirty place, such as in the sandpit
-
We talk for a variety of reasons, for example:
-
to joke
-
to argue
-
to talk about an experience
-
to discuss.
It is unlikely that any one communication method or system would meet a persons needs in all of these situations. Children who use AAC often need a variety of methods and systems to let them communicate throughout the day and night!

When deciding on the best AAC device for a child or adult, it may be useful to consider the following:
-
Giving a person an AAC communication system does not mean they will show an interest in using it - AAC systems are tools, they do not provide the interest or ability to communicate.
-
Read up on the information on the Assessment page of this site.
-
Check the information in the What's important about AAC? section of this page.
-
Prescription of a voice output communication device requires careful consideration and a variety of information and input from others. For more information, check out the following sites in the External sites list at the bottom of this page:
-
AAC Connecting Young Kids (YAACK) - look at the 'Issues with Different AAC Devices and Systems' section.
-
Washington University AAC page - follow the links for 'Understanding AAC Features'.
-
Remember that an AAC system should not be recommended without looking at the whole communication picture - the best result is usually obtained when the speech pathologist co-ordinates all the steps involved - the speech pathologist can also work out the most suitable type of AAC system , together with the child, their family and other therapists - these people can also be supported by therapists from the NovitaTech Support Team, if needed.
