Artificial intelligence no longer just writes texts or creates images. Today, it can also copy your voice with frightening accuracy. What’s particularly worrying is that scammers don’t need long recordings to do this: a few seconds of audio recorded during a call are enough.
That’s why a simple answer like « yes, » « hello, » or even « mhm » can become a tool for fraud, identity theft, and financial fraud.
The voice is no longer just a way of speaking. It is now a biometric data point that is just as valuable as your fingerprint or your face.
Your voice is a digital signature.
New technologies can analyze tone of voice, intonation, rhythm and way of speaking. They use it to create a digital model that can reproduce your voice as faithfully as if it were your own.
Once a criminal has this model, they can:
Call family members and pretend to be you.
Send voice messages asking for money.
Authorize payments
Access services that use speech recognition
And all this without your presence.

Even a simple « hello » can trigger a scam.
Many automatic calls are only used to check whether there is actually a person at the other end of the line.
When you say « hello », the system knows that your number is active and your voice can be recorded.
In addition, this short greeting provides them with enough material to start with the simple cloning of voices.
A safer strategy is:
