HISTORY

NSA had a longstanding interest in speech communication, carrying
on intramural research and supporting extramural research. The 
funding of the Glace-Holmes synthesizer ("JAWORD") was just one
rather minor part of the extramural program, which included at one 
time or another support of work at Haskins Laboratories, MIT, 
University of Michigan, Ohio State University, and the University 
of Southern California. The synthesizer was modeled on the JSRU 
parallel synthesizer [see SSSHP UK JSRU], with some minor engineering
improvements. The copies manufactured on contract by Electronic
Associates, Inc., were made available without charge to academic and
government researchers. Distribution to the academic recipients was 
made through Office of Naval Research (ONR) equipment loans.

PROJECT: DESIGN OF A TERMINAL ANALOG SYNTHESIZER (19   - 19   )

     Speech Research," a proposal circulated among prospective
     users, December, 1965.  **** need copy ****
 
 
A development system using a synthesizer obtained from JSRU. 
(See SSSHP UK JSRU).

     controlled on-line speech synthesizer system, Digest of
     technical papers, 1966 IEEE International Communications
     Conference, Paper TA 18.1, pp. 104-5, Philadelphia, IEEE.
     Parallel resonance synthesizer connected via D/A converters
     to Digital Equipment Corp. PDP-1, and controlling program, 
     AUTOMAT. User can construct synthesizer control data directly
     or as breakpoints of straight-line segments. (I)

Design of a manufacturable version of the Holmes and Shearme synthe-
sizer (see SSSHP UK JSRU).  
 
 
1968 Glace, D.A. "Parallel resonance synthesizer for speech
     research", J. Acoust Soc Amer, 44, 391 (A) (1968).  (I)

     Glace, D.A., "A parallel resonance synthesizer for speech
     research," Electronic Associates Incorporated, undated
     draft. Description of synthesizer as extension of Holmes 
     and Shearme synthesizer at JSRU. Formant tuning was 
     accomplished by pulse-ratio modulation of the loop gain of
     the operational amplifier formant circuits.  Computer control
     was accomplished by nine D/A channels.  Called the "Glace-
     Holmes synthesizer", or "JAWORD synthesizer". Addition of 
     fricative resonators and mixed excitation. Block diagram and 
     range of synthesizer parameters.

              Holmes/Shearme synthesizers.)
