2 Communication impairments  Speech-motor impairments Having difficulty using their vocal cords, facial muscles or breathing organs to produce and/or control their speech Parkinson ’ s disease, cerebral palsy, multiple sclerosis, muscular dystrophies  Language-cognitive Having problems on a cognitive level when their ability to receive, process and produce spoken language is disturbed Stroke, Brain injuries, Alzheimer ’ s disease

3 Impacts of communication impairments  Communication impairments have a major effect on the person ’ s social contacts  social isolation  non-intelligent  Self-esteem and self-respect can be diminished

4 Assistive technology (AT) for communication impairments

5  Communication impairments are more complicated to solve than vision, hearing or physical impairments  The most important thing to remember is to be willing to communicate and to allow the person time to communicate

6 Augmentative and Alternative communication (AAC)  Augmentative and Alternative (relpacement) Low-tech and high-tech Dynamic and static Simple and complicated

7 Low-tech devices  Non-electronic systems or devices such as picture communication boards and charts or paper and pencil  Simple electronic communicators they offer the user a quick, powerful and flexible method of communication

8  Pointing to, or touching, the required symbol on a display is a common method of accessing a low-tech communication system  It is also possible to use scanning techniques ( ‘ listener scanning ’ ) to access a low-tech communication system

9 Direct selection (pointing) and indirect selection (scanning)

10 High-tech devices  Simple or sophisticated electronic devices including simple communicators, dedicated communication systems and computer systems programmed to provide communication capabilities

11  Computer systems consist of a special purpose computer and software with symbol library, and digitised sound or a speech synthesiser can be used for output

12  Dedicated communication aids Designed solely for the means of providing an alternative to oral speech or to augment an individual ’ s speech
