Talking like Mr Blobby.

The Cybermen’s voices have evolved almost as much as their costumes over the years. They were originally provided by Roy Skelton, who later went on to voice Zippy and George from Rainbow, and were created by the voice artist deliberately placing completely the wrong inflections on all the words.

Later Cyberman voices were created using speech devices given to patients who have lost the use of their vocal cords. Place the gadget against the throat and mouth the words - and voila! instant robot voice.

Modern Cybermen sound a lot like Mr Blobby although, oddly, this doesn’t seem to make them any less scary. Real Time sound designer Alistair Lock uses a gadget called a harmonizer that repitches the original speech by -2 and -4 semitones, plus a sound manipulator know as a vocoder, as used extensively by Cher.
