With the rapid growth of artificial intelligence, phone scams have reached a new level of sophistication and danger.
It’s no longer enough to simply ignore fake texts or suspicious emails — now, just a few spoken words during a call could be used against you without your knowledge.
Your Voice: A New Target for Cybercriminals
Your voice, once just a personal trait, has become a valuable asset for digital fraudsters.
Thanks to AI’s power to mimic tones, accents, and even emotions, criminals can now record and replicate your speech to commit crimes from identity theft to fake bank approvals and forged contracts.
In this new reality, a few casual words may be all it takes to trigger a scam.
The Danger of Saying “Yes”
One of the biggest risks comes from a single word: “yes.” Scammers use recordings of your affirmative answers to authorize fraudulent transactions or legal agreements — a method known as “yes fraud.”
Once they have your voice saying “yes,” they can manipulate it to mimic your approval in audio-based verifications.
What to do instead:
Avoid direct affirmatives. Use neutral responses or questions that force the caller to identify themselves, such as:
- “What’s the purpose of your call?”
- “Who am I speaking with?”

Even Simple Greetings Can Be Risky
It’s not only “yes” that can endanger you. Common greetings like “hello” or “hey” can also help scammers. Automated systems use these recordings to confirm that your phone number is active and that your voice is authentic. By simply greeting an unknown caller, you may be confirming your identity for future fraud attempts.
