Abstract:

Work has been directed toward the solution of detail problems in refining the prototype models. A word synthesizer has been completed and fully equipped with magnetic tape fragments containing pre-recorded spelled-speech letters developed by Professor M. Metfessel of the University of Southern California. This prototype model can compose whole words up to 15 letters long and read them out at rates up to 8 letters per second. Continued work on the scanning array of photocells has resulted in an arrangement which will recognize all the lower case letters of the alphabet. It also appears possible to extend the recognition capability of this array, by certain modifications, to include capital letters, numerals, and selected symbols. Logic matrices have been developed to decode the photosignals from the scanning array and convert them into a 5-bit code which then controls the output of synthesized spelled-speech. Author
