Short answer
Yes, it can be a scam – even if the voice sounds real. AI can imitate voices from short recordings, and on the phone this is hard to detect reliably. The most effective protection is independent verification: end the call, call the person back yourself on the number you saved and never transfer money under time pressure.
What’s behind these calls
AI can imitate voices
Short voice recordings, for example from social media videos, are often enough to imitate a voice. A familiar voice is therefore no longer reliable proof of identity.
Technical clues are not enough
Choppy speech or poor sound quality can be a hint. But good sound quality doesn’t mean a call is genuine. Don’t rely on your ears – rely on independent verification.
Not every shock call is a deepfake
Many scam calls don’t use AI at all: supposed police officers, doctors or lawyers report an accident, or someone sobs so the voice is hard to recognise. The displayed number can be faked too. The protective rules are the same in every case.
Typical warning signs
- A supposed emergency: accident, arrest, hospital, lost phone
- Extreme time pressure – something must happen right now
- Demands for money, valuables, gift cards or a transfer
- A request for secrecy, even towards other relatives
- An unknown or supposedly new phone number
- Unusual style of communication, different form of address or wording
Step by step
Example: on the phone you hear your daughter’s distraught voice. She says she caused an accident, then a “police officer” takes over and demands bail immediately. You are told not to tell anyone.
- 01
End the call
Hang up, even if it feels rude. This breaks the pressure and gives you time to think.
- 02
Call back yourself
Call the supposed person on the number you saved yourself. Don’t use redial or any number given to you during the call.
- 03
Involve a second contact
If you can’t reach the person, ask another family member, partner or friend whether everything is all right.
- 04
Use a personal check question
If a conversation continues, ask a question whose answer can’t be found online. It’s an extra hurdle but doesn’t replace calling back.
- 05
No money under time pressure
Don’t transfer money, hand over valuables or buy gift cards until you’ve confirmed the situation independently.
- 06
Never share logins or TANs
Neither family members nor your bank or the police need your passwords, PINs or TANs on the phone.
- 07
If unsure, call the police
If you’re unsure whether an emergency is real, dial 110 yourself. If money has already gone, inform your bank immediately and report it to the police.
Prevention in the family
Agree a family code word
A word only you know, used in real emergencies. It’s an extra hurdle but no absolute protection – for example if it’s passed on or extracted under pressure.
Set a call-back rule
Agree: requests for money by phone or message are always confirmed by calling back on the known number first. That makes it easier to hang up without guilt.
Share less publicly
The fewer voice recordings, family names, travel plans and relationships are visible publicly, the harder a convincing deception becomes.
Talk about it
Talk to parents and grandparents about these scams. People who know them react more calmly when it happens.
Checklist
- I hang up when money is demanded under time pressure.
- I call back on the number I saved, not via redial.
- Our family has agreed a call-back rule and a code word.
- I never share passwords, PINs or TANs on the phone.
- I know: a familiar voice or number is no proof.
- Older relatives know about the scam.
Common mistakes
- Relying on your ears because the voice sounds exactly right.
- Assuming deepfakes can always be spotted by poor sound quality.
- Trusting the displayed number – it can be faked too.
- Letting yourself be pushed into secrecy and asking no one.
- Treating the code word as certain proof.
Frequently asked questions
Can I reliably recognise an AI voice?
No, not reliably. Inconsistencies can be clues, but good fakes sound very real. Calling back on the known number is safer.
What should I do if my child supposedly needs money?
End the call, call your child on the saved number and ask a second person if needed. Only act after independent confirmation.
Does a family code word help?
It can be an extra hurdle. It’s not absolutely safe. Always combine it with calling back.
Can a familiar phone number be faked?
Yes. The displayed number can be manipulated. That’s why you should call back on the saved number rather than use redial.
I’ve already paid – what now?
Inform your bank immediately to try to stop the transfer and report it to the police.
