Thanks for posting. I always wanted to emulate the original 1930's vintage Voder speech synthesizer in software. I wonder if anyone's done it yet. The Voder was not computer controlled, it had to be played by an operator, much like playing a piano.

That's what got me interested in speech synthesis as well. It seems very possible to do in software, the patent is quite interesting to read : http://www.google.co.uk/patents/US2121142. Not sure when it expires these days...
