Rice on the origins of Computalker Consultants and the Computalker 
CT-1 Synthesizer.

Commercial formant synthesizer card CT-1 for 8080-bus micro-
computers.  Nine-channel formant synthesizer.  Control data
at 100-bytes/sec per channel.  Software module for conversion
from phonetic input to synthesizer control signals, based on the
work of Dennis Klatt at MIT (see SSSHP USA MIT page), with
Klatt's assistance. Klatt requested his involvement be kept
confidential. [Editor: Personal communication from D. Lloyd 
Rice. This was about the time that Telesensory Systems, Inc. 
was talking to MIT about using Klatt's work in a reading machine
for the blind (see SSSHP USA Telesensory Systems page.)]
