The use of optical character recognition (OCR) systems combined with speech synthesis (computer-generated speech) has become increasingly accepted as a means of compensating for reading disabilities. These OCR systems, or reading machines, convert printed text to spoken language so the user can hear and see written words. These technologies are now marketed internationally (for example, WYNN®, Kurzweil 3000®), commonly found in assistive technology centers serving individuals with learning disabilities, frequently exhibited at LD conferences, generally considered in assistive technology evaluations for students with LD, and regularly discussed in publications on LD and assistive technology.
