ABSTRACT
Spellex is a system developed to aid the blind in the use of computer and office equipment without sighted help. It consists of a digital spelled speech generator interfaced with a number of instruments by digital electronic circuits. Voice is produced by two specially programmed read only memory chips. Standard C-MOS components are used in the design of the spelled speech generator so that the processor can be easily implemented using the latest large scale integrated circuit technology. As it now stands, Spellex provides voice for standard input and output terminals, punch card reader, paper-tape punch and reader, calculator, electric typewriter and the Lexiphone reading machine for the blind.
