Adaptive communication systems for patients with mobility disorders.
An adaptive communication system has been developed for individuals with mobility disorders. It uses specialized computer software and hardware that compensate for this disability. For an individual with a motor-control impairment who is not able to use a keyboard effectively, a computer voice-recognition technology now removes this communication barrier. Speech-recognition systems consist of three basic components: speech processing, speech recognition, and speech understanding. The new Dragon Dictate (Dragon Systems, Inc., Newton, Mass.) is the first large-vocabulary speech recognition system in the personal computer industry that interactively learns a user's vocabulary and mode of speaking and responds to natural language rather than to limited sets of words. This speech-recognition system requires a microprocessor, a display monitor, a printer, and specific software packages, including word-processing and enhanced memory-management software. Important considerations in the use of this speech-recognition system include microphone positioning and training of the system. With the advent of this new voice-recognition computer system, another communication barrier between the disabled and society has been overcome.
