Visit LINC to learn more about the variety of Augmentative and Alternative Communication devices that are available in the marketplace. Imagine how frustrating it is to know exactly what you want to say, but you cannot communicate your thoughts because of speech impairment. Communication difficulties can stem from conditions including stroke, traumatic brain injury, cerebral palsy, ALS, autism, Downís syndrome, developmental delays and other causes. AAC finds ways other than natural speech to improve communication success and decrease isolation and frustration caused by not having effective means of communication. AAC strategies range from simple communication boards to speaking through a communication device. The three basic categories of AAC devices are no-tech, low-tech and high-tech.

Ý

No-tech strategies include sign language, gestures, and eye gaze. The use of simple communication boards with alphabet letters, words and phrases, or symbols and/or pictures representing specific messages can be very effective. Low-tech devices include digitized communication devices that store recorded messages retrieved by pushing a switch or button on the device. Low-tech communication devices generally feature whole word/whole message communication in which messages are represented by words and/or picture symbols.

Ý

High-tech AAC devices include a wide range of computerized devices featuring synthesized speech and multiple access methods such as pointing, single and dual-switch scanning, infrared pointer, and mouse/joystick. Synthesized speech allows full text ñbased communication. Common high-tech communication devices are DynaVox, DynaMyte, DynaWrite, Pathfinder, Vantage and Vanguard. A personal computer can also be used as a communication device by installing communication software.

Finding the best approach is an individualized process because each person is unique with special needs to consider. Individuals should try many different devices and approaches to be sure they have adequate information to make an informed device selection. It is advisable to begin with a speech language pathologist. LINC will work with your SLP and arrange for you to try out a variety of approaches.
