“Call and check the voice” worked for decades. It has stopped being reliable: a voice is cloned from a short recording, and the recording comes from your own posts.
The material comes from stories, voice messages, a video from a party, a talk at work. Nobody needs to record you separately.
How it is used
- A call “from a relative” in trouble. The voice is familiar, the line is bad, the request urgent — bad audio conveniently masks the flaws in the synthesis.
- A voice message from a hijacked account. More convincing than text, and therefore more effective.
- A call “from your manager” asking you to pay an invoice urgently. A scheme aimed at companies, but it reaches small businesses too.
- A video call with a swapped face. Still rare and requiring preparation, but no longer science fiction.
Signs of a fake
| What you notice | Why it happens |
|---|---|
| Even intonation with no pauses for thought | Synthesis reads a text; it does not converse |
| No answer to an unexpected question | The script was written in advance |
| Insisting the line is bad | Noise hides the flaws in the synthesis |
| Avoiding a video call | Video is noticeably harder to fake |
| Odd stress in names and place names | Words outside the training data |
| Never laughs, never interrupts | Live speech does not sound like that |
What to do instead of recognising a voice
-
Hang up and call back yourself
To the number in your contacts, not the one that called. This is still the most reliable check, and synthesis does not get around it.
-
Ask something with no answer online
Not “what is the dog called” — that is on social media. Something like “what did we eat last Sunday” or “where is the blue mug”.
-
Agree a code word
One word for the family, spoken with any request for money. Choose it in advance and do not store it in a chat.
-
Take a pause
Every scheme breaks on delay. “I will call you back in ten minutes” is a sufficient response to anything.
What lowers the risk in advance
- Public stories with your voice
- Voice messages in public chats
- Recordings of talks in the open
- A public list of relatives in your profile
- A private profile and a limited audience
- A family code word
- The habit of calling back yourself
- Having this conversation with older relatives
The schemes that use a cloned voice are covered in messenger scams, and the conversation with parents separately.
