Be careful what you say! These are the words you should NOT use to avoid extortion with AI

By Vitia

In the age of artificial intelligence, phone fraud has taken an alarming turn. It’s no longer just scams with fake messages or misleading emails: now, with just one word, you can become a victim without realizing it.

Your voice, that very personal and non-transferable tool, can be recorded, duplicated and used to commit crimes. In this article, we explain what words you should never say on certain calls and how to protect yourself from new digital extortion methods that use AI to steal your identity.

Words You Should Never Say on a Call If You Want to Avoid Being Extorted

Today’s scammers are no longer just after your data… they look for your voice. With artificial intelligence technologies, they can clone your tone, your words, and even your emotions. Therefore, what you say when answering the phone can be used against you, without you knowing it.

1. “Yes” – The most dangerous word in a suspicious call

A simple statement can be recorded and used to authorize banking operations, accept false contracts or validate transactions. The so-called “yes fraud” is based on getting your voice saying this word and then inserting it into manipulated recordings.

Advice: Instead of saying “yes,” respond with neutral phrases such as:
“What is the reason for the call?”
– “On whose side?”
– “I don’t confirm anything over the phone.”

2. “Hello” – Number and Voice Validation Trigger

When you say “hello,” you’re signaling to the scammer’s system that your number is active, that someone is answering, and most of all, that the voice is clean and usable. Many robocalls are designed to detect that greeting as a starting point for recording.

Advice: If the number is unknown or appears as private, wait a few seconds before speaking. Let the other identify first. If it is important, they will insist.

3. “Aló” – Key to start a fraudulent automated process

This classic greeting in phone calls can be used as a trigger signal for automatic fraud systems. Once your voice is recorded saying this word, they can splice it into other contexts to make it look like you agreed to something.

Advice: If they call you and you don’t recognize the number, avoid answering directly with “hello” or “hello”. You can start with “Who do I talk to?” or “How can I help you?”

Why are they looking for your voice? The new currency of digital fraud

With the advancement of artificial intelligence, cloning a voice is no longer science fiction. With just a few seconds of audio, criminals can mimic your voice very realistically. Then, that voice is used to:

  • Make calls to your contacts by simulating an emergency.
  • Authorizing purchases or transfers in banks with voice recognition systems.
  • Validating false “legal” contracts or recordings.

How to protect yourself from these new digital traps

1. Don’t talk to strangers on the phone without verifying who’s calling.
Always use verification phrases such as: “What is your name and what company are you calling from?” before giving any answers.

2. Avoid answering telephone surveys or automatic recordings.
They’re often just an excuse to capture your voice.

3. Check your bank accounts periodically.
If you see strange movements, call your bank immediately.

4. Block suspicious numbers.
And report them to your supplier or the consumer protection agency in your country.

5. Never give out personal information over the phone.
No document numbers, no passwords, no addresses. If you are pressured, hang up the call.

In times where technology advances by leaps and bounds, your voice has become a vulnerable asset. And while it may seem far-fetched, a simple word like “yes” can give you more trouble than you might think.
Therefore, learn to respond calmly, intelligently suspicious, and cautiously. Sometimes, silence is also a form of protection.
