The Voder: 1939, the worlds first electronic voice synthesizer:



tooki:
It’s not called the “Voder 1939”, it’s the Voder, which happened to be made in 1939.

I wanna say this was discussed within some other thread on here not terribly long ago. (Edit: I remember now, it’s in the discussion of The 8-Bit Guy’s crappy video on speech synthesis.)

edy:
That's pretty cool. I wonder if they released any schematics or if it is possible to buy or build a kit using some modern chips to do the same thing? I'd love to put something together but instead of having to learn how to operate the keys precisely for 1 year of constant practice, feed it some text file and run it via Arduino.

Cyberdragon:
I'd still build the whole thing outta tubes. ;D Should just be plain audio tubes so cheap chinese ones should work just fine. But yeah, an alternative method of input such as computer control would be necessary for us noobs to use it.

Also, is this the origin of the modern synthesizer instrument the "vocoder"?

Well, it was done with a few transistors, however, you can convert it to tubes as it is only 3 or 4 oscillators and a noise generator.
