i had this post in wrong place so i have now moved it here:

there is also little "vocoding" or "robot voice" module that uses two CD4007 chips.

Quote:
...alterates the introduced speech so that it sounds like the voice of a robot. Adjustable effects. The device should be connected between the microphone and amplifier (or tape recorder).

and here is a short sample of robot voice.

i think it needs to moded or bended to get more results - but it´s nice if you don´t expect it to be a complete vocoding unit
