What are the 3 categories of AAC?
Based on their design characteristics, AAC devices appropriately are sub-divided into three categories:
- AAC devices with digitized speech output;
- AAC devices with synthesized speech output, which require message formulation by spelling and device access by physical contact direct selection techniques; and.
What are primary components of an AAC?
AAC uses a variety of techniques and tools to help the individual express thoughts, wants and needs, feelings, and ideas, including the following:
- manual signs.
- gestures.
- finger spelling.
- tangible objects.
- line drawings.
- picture communication boards and letter boards.

What are the major types of AAC systems?
What types of AAC are often used?
- Unaided AAC – or AAC that does not require a physical aid or tool. Facial expressions. Body language. Gestures. Sign language.
- Aided AAC – or AAC that uses tools or materials. Symbol boards. Choice cards. Communication books. PODD books. Keyboards and alphabet charts.

What are the 6 principles of AAC?
AAC System Design: Guiding Principles
- AAC systems are made up of a set of tools, techniques and partner strategies.
- AAC Systems are for multi-modal communicators.
- AAC Systems should be appealing.
- Students need to be taught how to effectively use AAC systems.
- Consider starting small.
- Include phrase-based messages.
How does AAC support language development?
However, we can be confident that for the great majority of people, AAC has no effect on speech development. Instead, people who use AAC may make gains and improvements in their speech. AAC provides a way to communicate more clearly. Using AAC can reduce frustration and help language development.
What is an AAC device for speech?

An individual may use one form of AAC alone or utilize a combination of unaided AAC, low-tech/light-tech aided AAC, and/or high-tech aided AAC forms. People who use AAC should always have access to their communication tools or devices.
What are the tools and techniques used in AAC?
AAC uses a variety of techniques and tools, including picture communication boards, line drawings, speech-generating devices (SGDs), tangible objects, manual signs, gestures, and finger spelling, to help the individual express thoughts, wants and needs, feelings, and ideas.
How does AAC differ from other means of language acquisition?
Language acquisition via AAC is different from language acquisition through typical means. Before acquiring AAC, children likely had (a) reduced means of expression and ability to control communication interactions and (b) fewer opportunities for exploring and interacting with their environment.
