What is an augmentative communication system?
A. Natural communication methods such as facial expressions and gestures, graphic symbols and sign language, as well as low-tech and high-tech communication aides are all considered augmentative communication. Augmentative or alternative communication systems are used by people who cannot speak and by those for whom speech is not an effective primary mode of communication. High-tech communication aides have speech output and complex programming capabilities and are used for individuals with severe speech impairments such as those seen in some individuals with Cerebral Palsy, head injuries, or progressive neuromuscular diseases. Many high-tech communication systems are multipurpose in nature, serving conversational, educational, and vocational needs. For example, some augmentative communication systems have speech and print output for communication. In addition, these systems can also be programmed to interface with a computer or an environmental control unit. Tanchak, T. L. & Sawyer, C
