AAC can be described in different ways. Understanding these different descriptions will help you know about the types of systems available, as well as help guide your decision-making as to which AAC system might be the best fit.

Types of AAC

Aided systems: Use external products and materials to help a user get across a message. These may include AAC systems such as core word boards, communication books or speech generating devices. Unaided systems: Use only the skills that are available to that individual and do not need special material or equipment. These could comprise body language, sign language, spoken language or facial expression.

As you can probably tell from these two types of AAC, a different combination is usually used for different intents and purposes. A competent communicator will often use both aided and unaided systems regularly.
