Voice Coder = Vocoder – analyses frequency ranges from the original and transforms it to another frequency section

Note: Kraftwerk used a machine called Votrax (Siemens), its a phonetic Generator, so it is NO Vocoder.. but of course they also used vocoders (a lot)..
Homer Dudleys VODER is one of the first made (late 1930ies/ very early 1940s)
(the vocoder was invented for the war (again) to encode and decode spoken messages..)

some models..
more about vocoders and what they do.. below..

a picture from my site, click here…jpg

Sennheiser Vocoder VSM201
made in 1978
this is a luxury 20bands vocoder
fully analogue
of course only the „creme de la creme“ used THIS, because it is really not cheap.. kraftwerk!manual can be found here.
as you can see: you can assign all bands freely and tune it!!
the „voice coder = vocoder“ is not only for „robotic“ voices like kraftwerk did. It’s also interesting for rhythmic sound sources.

you won’t worry about speech clearness anymore..
the vocoder was first a military device to encode speech signals.. but now „human kind“ uses vocoders for music! also a good thing!

–> all pics are much larger! just klick them to see them enlarged..
