Terms & Definitions


An aided system uses some sort of tool or device. There are two types of aided systems—basic and high-tech. A pen and paper is a basic aided system. Pointing to letters, words, or pictures on a board is a basic aided system. Touching letters or pictures on a computer screen that speaks for you is a high-tech aided system. Some of these speech-generating devices, or SGDs, can speak in different languages. ~ASHA
