Voice input for displaying sheets of paper of different sizes

Describes a voice controlled computer system to enable a multiple sclerosis quadriplegic patient to independently display sheets of paper of various sizes. The system is made up of two subsystems. The first is the voice input module comprising a microphone, a voice card, a voice recognition and control software and relay drivers. The second is the paper display drive mechanism consisting of opto-control mechanism, mechanical rollers, electric motor and the paper tray for holding and retaining papers of different sizes. To use the system, the user trains the recognition software for the key words desired for the tasks. Pilot tests show that the voice control software can be used to activate/deactivate all DC or AC devices connected to the computer relays with high accuracy. The paper turn drive mechanism was also successful in displaying sheets of paper from 3×5 to 8.5×11 inches
