Aided AAC is where the system uses materials, devices or tools to operate the AAC system.   

An individual and any communication partners will need to be taught to operate and understand/interpret the materials or tools to effectively use the system. 

Aided AAC systems are split into two categories based on the type of resource that is needed to use the system effectively. These categories are known as Low-Tech and High-Tech AAC systems. 

Low-Tech AAC systems do not use digital technology and rely on the user's ability to use hands or other body-parts to communicate.  These systems may use cues that relate to a person's senses, (e.g. pictures, audio or sign language).

Examples include: 

• Picture Exchange Communication System  (PECS)

• Printed descriptions or pictures (used by manually pointing to the pictures or passing them over). 

• Alphabet board (uses the alphabet to spell words). 

• Communication Books

Pros: 

• Does not require many resources. 

• Often inexpensive.  

• Relatively easy to teach and implement. 

Cons:  

• Can be more difficult to interpret exactly what is being communicated.  

High-tech AAC systems uses digital technology to function and relies on the user’s ability to interact with the systems that it operates (e.g. push buttons, select desired words on screen, use vocal commands etc.).  

High-tech AAC systems can be used for a range of different types of CCN as mose systems are able to be modified to fir needs. 

Examples of high-tech AAC include: 

• Tablet. 

• Computer software. 

• Speech Generating Device (SGDs) 

• An app on an iPad.

Pros: 

• Wide range of communication can be accessed (e.g. sounds/voice, pictures etc.) 

• Easy to use with a variety of people.  

Cons:  

• Can be expensive. 

• Must be maintained and/or replaced. 

• Must be kept charged and in working order.
