Analog Speech Synthesis

[Barry L Klein]

That is the kit that got me interested in electronic music!  It was in my
electronics class in 10th grade.  I tried making a keyboard for it so you
could play a tune....  Any extras?  Love to put it up on the wall!

Hi All, 

I came across something curious recently, an analog speech synthesis
experiment kit. It was produced in about 1964 by Bell Labs as a part of
their education program for computer and electronics students.

It includes a rather in depth book which discusses the fundamental
theories
of speech synthesis, all in purley analog terms. When this kit was sold,
the Votrax SC-01 was still over a decade away. The kit allows you to
construct an analog vowel synthesizer, comprised of a rectangle wave
generator, three L-C formant stages (ferrie bobbin type) and an audio
stage. By tweaking the cap values in the formant stages, the unit can
(rougly) produce all english vowel sounds, and lots of other strange
noises
in between.

Has anyone encountered anything else related to analog speech production?
Frankly, I've never seen anything else like it.
