How it works
A computer can make a fake picture, a fake video or a fake voice. These are often called AI fakes.
Some fakes are just for fun, and others are made as tricks. Clues can help, but fakes keep getting better.
No clue does not mean real. The big step is to check the source: where did this come from?
A voice can be copied from a short recording. What it asks for is the clue: money, a hurry, or "do not tell."
