Artificial intelligence (AI) is resurrecting "lost memories", recreating and reimagining the Beatles' singing. The fact that AI voices are simulated so realistically has also raised a series of ethical and legal questions, and even led to the emergence of telecom fraud.

In telecom fraud, scammers use AI software to scan voice recordings and copy them with up to 99% accuracy. Some models and algorithms can synthesize a fairly high-quality cloned sound in just a minute or less.
