How to Spot a Deepfake Video or Voice

Tap each term to learn the signs of a deepfake.

What a deepfake is

A deepfake is video or audio content that uses artificial intelligence to synthesize or alter a real person's face or voice, making it appear as though they said or did something they never actually did.

Check for unnatural blinking and lighting

Synthesized video sometimes shows blinking that's too infrequent or oddly timed, or lighting and shadow direction on the face that doesn't quite match the background, details worth looking at closely.

Check for a subtle mismatch between audio and lip movement

A slight timing gap between speech and lip movement, or mouth shapes that don't naturally match the sounds being made, can be a sign of synthesized video.

Notice an unfamiliar tone or awkward inflection

A synthesized voice can mimic word choice and general intonation reasonably well, but often fails to fully reproduce a specific person's breathing pattern, verbal habits, and emotional nuance, something someone who knows the person well may sense is off.

Verify urgent requests through a separate channel

If a video call or voice message urgently asks you to send money or share information, don't trust the recording alone. Call the person back on a number you already know, or confirm through another channel, before acting.

As the technology improves, spotting flaws by eye gets harder

Deepfake technology keeps advancing quickly, so relying purely on visual or audio flaws to catch a fake is becoming less reliable over time. That makes the habit of pausing before acting on a request, such as sending money or sharing personal information, and verifying through another channel more important than analyzing the content itself.

It's showing up in voice-impersonation scams too

Synthesizing the voice of a family member or acquaintance to create a fabricated emergency is an emerging form of voice-based phishing scam, so it's worth being familiar with how to respond to a suspicious urgent call in general, not just deepfakes specifically.

Frequently Asked Questions

Are there dedicated apps or services that can tell me if something is a deepfake?

Some companies and research institutions are developing deepfake detection tools, but a fully reliable tool that ordinary people can easily use is still limited. Verifying independently through another channel remains more dependable than relying on a detection tool alone.

What should I do if my face or voice was used in a deepfake without my consent?

Report the content to the platform where it's posted and request its removal, and if real harm has occurred, consider reporting it to your local law enforcement's cybercrime unit. Saving screenshots and links as evidence beforehand can help.
