A computer-based language learning tool for the handicapped

The needs of the vocally handicapped and the shortcomings of existing speech aids are identified in the context of how better speech aids may be obtained. The requirements for quadriplegics are discussed together with the alternatives to speech-aid keyboards. The problems and limitations of standard speech aid keyboards act as an introduction to the theme of software-generated-keys (softkeys). Softkeys are used in the human interface models developed to emulate a touch input speech aid. A speech board that can be driven from a standard IBM PC is described. The ultimate goal is that the same software program will present menus of information to the patient and receive an input choice from that patient in order to produce speech. The key factor is that any IBM PC compatible computer can be used to handle the user interface and the control of the speech board.<
