AAC stands for Augmentative and Alternative Communication.
AAC can be defined as any method of communication that supplements the ordinary methods of speech and handwriting, where these are impaired (Miller & Scott).
There are different levels of communication technology within the field of AAC – low, medium and high tech. These are defined by the level of sophistication of the technology used, from simple books and boards to complex computer-based machines. However, most AAC users will actually employ a mixture of methods.
Low Tech System – click to find out more
A low tech aid has no batteries or electronic parts. It is usually made up of symbols or text on a card or made into a book.
Medium Tech System – click to find out more
A medium tech aid has a battery but no complex electronic parts. These can usually be programmed quite quickly and are ideal for use throughout the day in groups or with different activities.
High Tech System – click to find out more
A high tech aid is powered by mains or a battery which usually requires a charger. It often contains sophisticated and complex electronic parts. It may contain a speech synthesiser or be able to record speech. These devices can take a considerable time to programme specific vocabulary required. The facilitator may require specific training to programme and support this aid.
By implementing one or more of these systems within a total communication programme, the aim is that the user becomes a successful communicator within their environment. Primarily, the main objective is for each user to feel involved, integrated, included in an interactive communication situation.
