Growing up, the first thing my friends did when they got audio software on PC was edit recordings of people to make them sound stupid. It was basic swapping answers from different questions.

Years later, I edited dialog from a movie (for my own use) to shorten or rearrange sentences in a way that very few people can detect, to remove profanity from clips I wanted to show to people who can't handle it.

Also, AIUI Hollywood has been splicing dialog for decades in ADR. Star Trek TNG had an episode in which a vocal resynthesis device played a role, so the idea is old.
