What is AAC?

Augmentative and Alternative Communication (AAC) is a set of methods and tools that help student with communication disorders or disabilities express themselves effectively. This may include low-tech and high-tech solutions such as speech generating devices and communication apps.

How AAC Works?

AAC helps students with language and language difficulties express their thoughts, needs and feelings and participate more fully in social interactions, education and daily activities. AAC is tailored to an individual’s specific needs and requires training and support from a trained professional, such as a speech therapist. Usage of AAC may vary according to individual needs. For better results, we recommend applying AAC method across activities and environments.


Types of AAC

Low-tech AAC includes methods such as picture boards, communication books, and alphabet boards. These methods are relatively simple, inexpensive, and easily modified to suit individual needs.

High-tech AAC include more advanced technologies such as speech generating devices (SGD) and computer-based communication systems. SGD communicates using synthesized or recorded speech, while computerized systems allow individuals to select words and phrases using specialized software or apps.

Choosing an AAC type depends on your student’s needs, skills, preferences, environment, and communication situation. A trained professional, such as a speech pathologist, can help determine which type of AAC is most appropriate and effective for an individual.
