What to Watch For
A couple of years ago you could tell in two seconds. That's over. Here's what still works.
The voices crossed a line recently. They pause. They say "um." They take a breath before they answer. The dead giveaway used to be that a robot sounded like a robot, and that giveaway is mostly gone.
So if you're waiting to hear something obviously fake before you get suspicious, you'll be waiting too long. The good ones don't sound fake anymore.
The bots keep getting better at sounding human, so the way you catch them keeps changing.
An AI on the phone is usually following a script. It's good at the conversation it expects and clumsy at the one it doesn't. So hand it something off the script:
None of these are foolproof, and the best systems are starting to get past them. But they'll catch most of what you run into today.
You don't have to play detective. Just ask: "Am I talking to a person or to AI?" A real business will tell you straight. That's the honest answer, and most legitimate ones give it.
What to do
If it matters, ask it outright. And for anything involving your money or your accounts, don't trust the answer either way. Hang up and call the company back on a number you already have. You started the call, so you know exactly who you reached.
That's how you handle it today. The trouble is the tech moves, so the answer does too. When the next trick lands, I'll send you the one that beats it.
