voice coder machine

The VODER was amazing. No text or speech input. The operators left hand had continuous control of the formants (analog band pass filters) and the pedals and right hand controlled pitch and volume. You actually had to "play" each syllable.
As "Waveboy" I made a voder plug-in for the Ensoniq ASR-10 in the 90's but never got to see the real one. Cool.

Ok, Im working on my Master's Thesis in Physical Modeling. I have been reading about the Voice Coder (VODER) and wanted to see it for REAL!! Wow, thanks for posting... Knowing the MATH behind it makes me appreciate what looks SOOOO SIMPLE but is actually very complex... WOW Homer Dudley 1928

This actually seems more like an early version of "Text-to-speech" than a vocoder since there's no speaking or singing into it.

Or Text...

Thank you for sharing this. Is this an alternative version of VODER, which was demonstrated in 1939 at NY World Fair ?

Can't say m'self, but it is the one that Bell Labs developed and is pointed-out in "The Bell Labs Song" also found on this site. And if you dig that, checkout the demonstration of the Bell Labs Digital Synthesizer (Laurie Spiegel Playing 1977 Bell Labs Hal Alles Synth). Amazing what about 40 years of tech progress can achieve (Seriously!).
