What is Augmentative and Alternative Communication (AAC)?

As a speech-language pathologist, I am guilty just as the next clinician of using professional terminology when trying to explain therapeutic techniques and tools.  “Augmentative and Alternative Communication (AAC)” is one of these words.  So, let me explain what this seemingly complicated tool is.

When children are unable to effectively communicate their wants and needs verbally alternative forms of communication are utilized.  These forms have a wide range, including anything that is not verbal communication.

These forms have a wide range, including anything that is not verbal communication.  These include aided and unaided communication methods.  Below are some examples:

Unaided (no materials required)

• Facial expressions
• Vocalizations (non-speech)
• Gestures
• Sign Language

Aided (materials required)

• Communication Flip books
• Pictures (schedules and also protocols such as “PECS”)
• Letter boards (letters on a board where the person spells out their thoughts)
• Switches (a button that is pushed to say a single message or activate a toy)
• Speech Generating Devices (SGDs are high technology devices used for communication.  They often look like computers.  These types of devices include, but are not limited to: GoTalk, Vantage, Sping Board, or Dynovox systems.)

Many children with severe communication impairments benefit from some form of Augmentative and Alternative Communication.  Most of the children I work with that benefit long term from AACs have a disorder like; Down Syndrome, Autism Spectrum Disorder, Aphonia (inability to talk), and Oral/Verbal Apraxia/Dyspraxia.

If you feel your child could benefit from AAC please discuss it with your speech-language pathologist or primary care physician.
