Augmentative and Alternative Communication (AAC)

Augmentative and Alternative Communication (AAC) is a key focus area for the speech pathology department of Novita. 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:

Augment means to add to or to enhance. For example, we can augment speech by using gestures, eye pointing and body language.

Alternative means a choice or a substitute. We can use alternative communication to speech by pointing to symbols, signing or by spelling.

Communication means to send and receive messages with at least one other person.

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:

  • develop language skills
  • decrease frustration
  • increase socialisation
  • increase participation
  • have control over what happens to them

AAC may 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)

AAC covers a large number of ways of communicating. It can include one or more of the following.

Natural communication methods, such as:

  • pointing and gestures
  • mime
  • facial expressions
  • body language

Methods that can be taught, such as:

Signing – this involves the use of a formal set of signs, or signs which are particular to an individual. Signing is useful to help children to understand language. The sign can be seen and held for slightly longer if needed, whereas speech disappears as soon as it is spoken. Signing can also be used as a means of expression with other people who know signs.

Object symbols – these are objects such as small versions or parts of objects which represent an activity, object or person (for example, a set of keys represents that its time to go in the car)

Photos, drawings, symbols – these are used like object symbols to represent words in a visual way

Communication boards and displays – these are sets of photos, drawings, symbols or words that are used by an individual for communication – .

Chat books – these are small books (often a photo album) that may contain photos, pictures, symbols, words and messages about a person

PODD Communication Books

Speech generating devices – communication boards or displays on a machine which speak a message when a particular button is pressed

Spelling – using an alphabet board or typing device to spell out words and messages

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 person’s 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!

Reading with A.A.C.Parental involvement – successful use of AAC involves support and active involvement of those who are in the child’s immediate environment – parents and caregivers are the key to AAC success. (graphic-communication group-child and parent).

Communication partners – there are lots of things that communication partners (those who interact with AAC users) can do which make a real difference to the skills an AAC user develops.

Opportunities to communicate – in order to develop and practise communication skills, the child (particularly in the early stages of using AAC) may need some extra encouragement to use their AAC system.

Vocabulary choices – the words and messages chosen for an AAC system are very important – if they are not useful or motivating to the child or listener, they will not be used.

Ongoing evaluation – an AAC system should be ever-changing, matching the needs of the user as they grow, learn and meet new people – communication needs are always changing, and an AAC system should change to meet (or anticipate) these needs.

Ease of use – for communication to be successful, it needs to happen as easily as possible for the user and as quickly as possible for the listener – many factors will need to be considered to achieve this goal.

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.

Prescription of a voice output communication device requires careful consideration and a variety of information and input from others.

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 Assistive Technology Service team if needed.

There are a number of different approaches and methods that may be used in AAC training. These include immersion and modelling.

Immersion is when all those around the child use the child’s augmentative and alternative communication system when communicating with them. The child should also be expected to use the system.

Modelling is demonstrating or showing how to do something by example.

Teaching, training and practise are very important in determining the success of AAC use.
