Imagine knowing exactly what you want but not having a reliable way to tell someone.
For some children, spoken language may not yet be enough to communicate their needs, ideas, feelings or choices.
This is where Augmentative and Alternative Communication (AAC) can help.
AAC refers to communication methods that supplement or provide an alternative to spoken language.
It can include simple gestures and signs, pictures and communication boards, or electronic speech-generating devices.
What Does “Augmentative and Alternative” Mean?
Augmentative
A communication method adds to existing speech.
For example, a child who speaks some words may use pictures to communicate more complex messages.
Alternative
A communication method provides another way to communicate when speech is not currently sufficient.
A child may communicate using pictures, signs or a speech-generating device.
AAC can therefore be useful for children who speak very little as well as children who speak but are difficult to understand in some situations.
ASHA emphasizes that the presence of speech should not automatically exclude a person from consideration for AAC.
Who Can Benefit From AAC?
AAC may support children who:
- Are nonspeaking
- Have limited spoken language
- Have difficulty being understood
- Are developing speech slowly
- Have motor speech difficulties
- Have autism
- Have cerebral palsy
- Have intellectual or developmental disabilities
- Have communication difficulties associated with other conditions
AAC is not limited to one diagnosis.
What Does AAC Look Like?
AAC can be very simple.
Gestures
Pointing, waving, nodding or other meaningful movements.
Signs
Manual signs can provide another way to express messages.
Pictures
A child may select a picture representing an object, activity, person or action.
Communication Boards
Pictures, words or symbols can be organized into a board.
Speech-Generating Devices
Electronic systems can produce spoken messages selected by the user.
The best system depends on the individual child.
Does AAC Mean My Child Will Never Talk?
No.
This is one of the biggest misconceptions about AAC.
AAC does not mean giving up on speech.
ASHA states that AAC does not hinder speech development and may support spoken language development.
For some children, AAC may become a long-term communication method.
For others, it may be used alongside developing speech.
The important goal is effective communication, not forcing one communication method on every child.
Should a Child Be Able to Talk Before Using AAC?
No.
There is no requirement that a child must reach a particular age or developmental level before AAC can be considered.
ASHA states that there is no “too young” age for AAC and recommends considering AAC when a child demonstrates difficulty developing spoken communication.
What Can a Child Communicate With AAC?
AAC should not be limited to requesting objects.
A child may use AAC to communicate:
- “I want water.”
- “No.”
- “Help me.”
- “My turn.”
- “I'm finished.”
- “I don't like this.”
- “Look!”
- “Where is Dad?”
- “I'm tired.”
- “I want to play.”
- “That is funny.”
This is why AAC should be viewed as a language system, not simply a behavior-management tool.
How Do Children Learn AAC?
Children generally need direct teaching and opportunities to practise.
Adults can:
- Model how to use the system
- Respond when the child communicates
- Create meaningful opportunities to communicate
- Use AAC during everyday routines
- Avoid requiring communication only when the child wants something
- Give the child enough time to respond
Communication should happen throughout the day, not only during therapy.
What Is PECS?
PECS stands for Picture Exchange Communication System.
It is a specific structured AAC system developed by Andy Bondy and Lori Frost.
PECS teaches functional communication using pictures through a systematic sequence of skills.
It is therefore more than simply giving a child picture cards.
Hope Kids can provide further information about PECS through its communication support programs.
How Do I Know Which AAC System Is Right for My Child?
There is no universal “best AAC system.”
Assessment should consider:
- Motor abilities
- Vision
- Hearing
- Communication skills
- Language
- Cognitive abilities
- Preferences
- Access method
- Family routines
- School environment
- Communication partners
AAC decisions are ideally made collaboratively with the child, family and relevant professionals.
How Can Parents Support AAC at Home?
Use AAC during normal activities:
Mealtimes
Model words such as:
more, finished, drink, eat, different
Play
Model:
go, stop, again, my turn, your turn
Getting Dressed
Model:
shirt, shoes, socks, help, finished
Outings
Model:
car, shop, toilet, home, stop
The more naturally communication is incorporated into daily routines, the more opportunities the child has to use it meaningfully.
How Hope Kids Can Help
Hope Kids supports functional communication through speech and language therapy and AAC approaches where appropriate.
Communication support may include gestures, pictures, communication systems and other AAC methods depending on the child's individual profile.
The goal is to give every child a reliable way to communicate while supporting the development of speech and language where appropriate.
