you can do all those cheesy manipulations that Cher uses on "Believe" to make her voice sound robotic (didn't we get enough of that in the 1970s with Peter Frampton?)...

The difference here being that Cher's cheesy manipulations relied on a piece of computerized equipment, while Peter Frampton's relied on his own skill as a vocalist and guitar player. The device he used was a tube that relayed the output of his guitar speaker to his mouth, where by forming the word, it sounded like his guitar was "Singing" similar to the device used by people who have had their voiceboxes removed.
