Free AI Tools Cloned a Journalist's Voice and Fooled Their Family
A ZDNet journalist used free AI voice cloning tools to clone their own voice, then placed a simulated scam call on family members who failed to detect the fake. The experiment showed how little skill or money a would-be fraudster now needs to impersonate someone a family knows and trusts.

I.How it happened
The journalist fed a short sample of their own voice into a freely available AI cloning tool and generated audio that their family could not distinguish from the real thing. No subscription, no technical background, and no money changed hands. The simulated call used a pressured scenario designed to mirror the kind of urgent request a real scammer would make, and family members who hear that voice every day answered without suspecting anything was wrong.
The experiment made one thing plain: the barrier to voice cloning has effectively disappeared. Anyone with a grudge, a scheme, or a few idle hours can now replicate someone's voice and call that person's family. The technology does not care how well the family knows the speaker.
Timeline
-
The Setup
The journalist found freely available AI voice cloning tools that required no technical expertise and only a short audio sample to produce a convincing voice clone.
-
The Attack
Using the cloned voice, the journalist placed a simulated scam call to family members, presenting a fabricated urgent scenario to test whether the fake voice would be believed.
-
The Impact
Family members who knew the journalist well did not detect the cloned voice during the call, showing the technology can deceive even close relatives.
-
The Discovery
The journalist revealed the experiment to family members after the call, confirming they had been speaking with an AI-generated voice clone the entire time.
-
The Fallout
ZDNet published the findings as a consumer safety warning, documenting that realistic family impersonation is now accessible to anyone with a phone and an internet connection.
II.The damage
No money was lost and no real harm was done because the call was a controlled experiment. But the result was a precise blueprint for fraud: free tools, a convincing clone, and family members who had no way to tell the fake from the person they love. "I didn't even question it," one family member said after learning the truth.
III.What would have stopped it
Our analysis: prevention guidance, not part of the reported facts
If the family had been using Trust Onion, the journalist could have asked any caller claiming to be them: "What are the words?" A scammer using even a perfect voice clone cannot answer. The three codewords are calculated privately on each family member's device, rotate every 60 seconds, and never pass through any server a fraudster could reach.
The experiment proved that voice alone is not enough to confirm identity. A single shared question, asked before any money moves or any emergency plan is followed, turns a convincing clone into an obvious fake.
Frequently asked questions
What did the ZDNet voice cloning experiment show?
A ZDNet journalist cloned their own voice using free AI tools and placed a simulated scam call on family members. The family did not detect the fake, showing that realistic voice cloning is now accessible to anyone and can fool people who know the speaker well.
How much does it cost to clone someone's voice with AI?
The ZDNet experiment showed it can cost nothing. Free, publicly available tools produced a voice clone convincing enough to deceive close family members, with no technical expertise required.
How can families protect themselves from AI voice cloning scams?
Families can share a set of private rotating codewords using Trust Onion. When a caller claims to be a loved one, ask 'What are the words?' A scammer using a voice clone cannot answer, exposing the fake immediately regardless of how realistic the audio sounds.
Can you tell an AI voice clone from a real person on a phone call?
The ZDNet experiment suggests you often cannot, even when you know the speaker well. The only reliable check is something the AI clone cannot know: a private, time-sensitive codeword agreed in advance.
What should I do if I get a suspicious call from a family member's number?
Ask for the current codeword before responding to any request. You may also call back on a number you know independently, but a successful callback does not prove the original caller was legitimate. The caller must still know your family's private Trust Onion three words. Use common sense and alert authorities if you believe someone may be in danger.
Help Your Group Verify Calls
Friends, family, teams, and clubs can share three rotating words. Ask the caller to give them first; compare privately in your app.
