Daisy style (IBM704) speech synthesis, "Voder" style speech synthesis

Wish to replicate it on max. Not really sure how IBM 704 did it, so don't know how to approach it.
not sure about the Voder either.

anyone has any sources on this?

Assuming you know about formants, and voiced & unvoiced sounds, you will learn a lot by studying the standard Max example classic_vocoder effects -> classic-vocoder-folder.

Thanks a lot! that seems pretty close.

I thought there was more to daisy than just vocoding :( I thought there was some real formant-synthesis involved.

if you're into that kinda thing, the sonivox is cool too, it's similar to talk box. https://www.youtube.com/watch?v=blhqeWpwwkA

Ploki,
For Daisy, I think they used a source-filter synthesis, with 2 formants defining the vowels.
I gave you the Moog-like vocoder reference because the synthesis algorithm is basically the same.
Difference is that in the Moog imitation, the "formants" are fixed: actually a bank of 15 filters or so.
For Daisy, I think they did use 2 moving formants to get the vowels.
