Abstract :
A synthetic voice aid for speech disabled people is presented in this work. The system is based on the Morse code, given through four keys. A PIC was used to detect and decode Morse code as well as to make the translation to ASCII code. The data processing was performed by an MC68HC11 microcontroller. Voice was generated by a V8600 commercial synthesizer. The aid includes a liquid crystal display for text exhibition, that serves as a feedback reference. The display was mounted on a structure strategically located to avoid interference with the frontal visual field.
