AI voice cloning has reached the point where fraudsters can convincingly imitate human voices. Unfortunately, research shows that we are not particularly good at distinguishing voices.
Take, for example, the case of one user X, who wrote: “My wife called and said she forgot her wallet and needed a credit card to pay for gas.
Except my wife was home with me and drives a Tesla. The same voice, a little… unusual, strange intonation, but 100% it sounded the same as her. If it wasn’t there and it wasn’t the gas, I would have bought it.

I entertained myself for a while to get more enjoyment out of it, I was so confused. This must be some kind of voice deepfake. The responses were too fast for the AI, I think it was a voice filter. I wish I had thought to write this down.”
It is unclear whether this particular call used a generative AI or real-time voice filter. One thing is clear: the days when recognizing someone’s voice was enough to prove who was on the other end of the phone are gone, and I’m not the only one who finds it terrifying.
When news of this story surfaced on Reddit, some people were skeptical about whether it actually happened, but there were plenty of people with similar stories. “This just happened to me last week,” one user said. “They called my aunt and grandmother and said they were a lawyer and that I was in jail and needed to be released.”
“Relative in Need” scam
According to the 2026 document Assessing the ability of AI models to automate voice phishing attacks A study of 4,100 American adults by Fred Heiding and colleagues found that up to 36.1% said they would agree or were unsure if they would agree to comply with an AI “relatives in distress” scam.
It is important to note that this figure reflects self-reported willingness to comply, rather than the number of people who were actually tricked into giving up money. Researchers describe this as a measure of susceptibility to fraud rather than observed behavior.
The researchers also found that persuasiveness matters more than how human a voice sounds, and that people who regularly used AI were no better at recognizing synthetic voices than people not exposed to AI.
While the scam of tricking people into thinking their loved ones need money may be an old one, AI makes the danger especially real. If the scammer really looks like your loved one, how will you know it’s him?
One answer is to come up with a family code word today. It doesn’t have to be complicated – just something that everyone knows and that a scammer is unlikely to guess or find online.
There is an even simpler precaution: hang up and call the person back at a number you already know. If your son, daughter, partner or parent calls you out of the blue and urgently asks for money, don’t rely on the voice sounding right. End the call and contact them yourself.
The Ferrari deepfake case shows why some form of personal verification can work. In 2024, a Ferrari executive received messages followed by a phone call apparently impersonating CEO Benedetto Vigna. Suspicious of the call, the executive asked the supposed Vigna to name a book that the real CEO had recently recommended to him. The caller was unable to answer and the deception attempt failed.
Family Code Word essentially does the same thing. And you may need to start thinking about it today, if you haven’t already.
Can you trust your ears?
“The biggest impact of artificial intelligence is not on our devices, but on us,” says Mark Beer, head of consumer practice at Malwarebytes. “When people can no longer trust what they see, hear or talk to, the damage goes far beyond any fraud and affects the building blocks of our society.”
A Malwarebytes survey released in June found that 85% of people said it was difficult to distinguish a scam from a real one, up from 66% the previous year. Perhaps even more tellingly, 88% said it is becoming increasingly difficult to determine what content online is truly human and what is real.
And this problem is not limited to our ears. AI-generated images and deepfake videos are increasingly challenging the assumption that seeing or hearing something with your own eyes is proof that it actually happened.
Previously, we could rely on a familiar voice as proof of identity, but it seems that in 2026 this is no longer enough. AI voice technology will only become more persuasive, so our behavior must change along with it.
Agree on a code word with the people closest to you now, and if you get a call asking for money out of the blue, hang up and call them back.
