LISTEN: Spotting Audio Giveaways

What natural human speech sounds like

Real human voices have imperfections: breathing sounds, slight pauses, emotional variations, and natural rhythm changes.

AI voice warning signs

Too Perfect

No breathing sounds, clicks, or natural pauses. The voice sounds overly polished and smooth.

Robotic Rhythm

Constant pace with no natural speed changes. Each word has the same emphasis.

Lip Sync Issues

In videos, the lips don't quite match the words being spoken. The timing feels slightly off.

Emotional Mismatch

The voice tone doesn't match the facial expression or the message content.

How scammers use AI voice cloning

Common scam: You receive a call or voice message that sounds like a family member or friend in distress, asking for money urgently.

What to do: Hang up and call the person back using a known phone number. Don't trust the voice alone.

Practice listening

Pay attention to voices in videos you watch online:

  • Does the speaker take natural breaths?
  • Are there emotional variations in their voice?
  • Do the lips match the words perfectly?
  • Does the voice match the person's age and appearance?
Key Takeaway: Real voices are messy. AI voices are smooth but lifeless.
