TL;DR: Spellex is a system developed to aid the blind in the use of computer and office equipment without sighted help and 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.
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.

TL;DR: Mandarin was synthesized using a computer-controlled speech synthesizer and it was shown that subjects could hear the synthesized passage with an encouraging intelligibility score of over 70% after less than an hour of exposure to the sounds.
Abstract: Mandarin was synthesized using a computer-controlled speech synthesizer. The four tones and the neutral one in the unstressed syllable were constructed by varying the pitch of the phoneme string. A passage and a list of single syllables were generated for an experiment. It was shown that subjects could hear the synthesized passage with an encouraging intelligibility score of over 70% after less than an hour of exposure to the sounds. The results also showed that the quality of the voice could be further improved by proper manipulation of the pitch.

TL;DR: Spelled Speech can be used as feedback by a blind typist to monitor her typing and correct her typing mistakes.
Abstract: Spelled Speech can be used as feedback by a blind typist to monitor her typing and correct her typing mistakes. The speech can be produced using a computer or using a small portable digital apparatus.

TL;DR: In this paper, a spelled speech or speech generator consists of a central processing unit (CPU), a first memory storing operating program signals for the CPU, and a second memory storing signals representative of predetermined portions of phonemes and repetition counts therefor.
Abstract: of the Disclosure A spelled speech or speech generator consists of a central processing unit (CPU), a first memory storing operating program signals for the CPU, a second memory storing signals representative of predetermined portions of phonemes and repetition counts therefor, an address bus interconnecting the CPU and an address input of each memory, an audio output port driving a digital to analog converter for providing an audio output signal, and a data bus interconnecting the input of the audio output port to an output of the second memory. The CPU is actuated to serially address predetermined ones of memory locations, whereby said phoneme-portion signals can each be repeated a number of times designated by said repetition count signals in a sequence and applied to the input of the audio output port to provide a complete phoneme signal. The size of the memory can be minized by storing only a few partial phonemes.
