What is the voice effect used in that 'Cher' and 'Im Blue'

[bucket]

You are all INCORRECT.

I happen to be in the possession of certain secret knowledge due to my proximity of the Diva herself.

..and now I will tell you the secret:

That sounds is Cher's REAL VOICE. She is an android, that is why she will live forever and never grow old.

I was hired in 1979 to give her a daily vagina massage, and she has never had a single GRAY PUBIC HAIR. Do you think this is unnatural? It is! And her vagina never smells like sweet fishies. Oh, no my friends....it smells like MOTOR OIL.

VROOOOOOOOOOOOOOOM.
