Yanny or Laurel

Origin: a vocabulary website recording

The clip is not synthetic and it was not made to fool anyone. It comes from vocabulary.com, which since 2007 has hosted pronunciation recordings for its dictionary entries. The recording in question is the word “laurel,” read by an opera singer credited as Jay Aubrey Jones.

The ambiguity emerged from how the file was recaptured. A high-school student — reporting differs on exactly who, with Wired naming Katie Hetzel of Flowery Branch High School in Georgia and the New York Times crediting Roland Szabo of Lawrenceville — played the recording aloud and re-recorded it, picking up room noise and compression along the way. Hetzel posted about it to Instagram on May 11, 2018, and a friend, Fernando Castro, turned it into a poll.

Going global

On May 12, 2018, the clip reached Reddit’s r/blackmagicfuckery, where commenters traced it back to vocabulary.com. Then, on May 15, 2018, YouTuber and influencer Cloe Feldman tweeted it with four words — “What do you hear?! Yanny or Laurel” — and the internet detonated.

A widely circulated Twitter poll drew more than 500,000 responses, splitting roughly 53% Laurel to 47% Yanny. Within 48 hours it was on every morning show. Ellen DeGeneres, Stephen King and Chrissy Teigen weighed in; so, inevitably, did the musician Yanni and the electronic artist Laurel Halo. Brands piled on with the usual awkward speed.

The actual explanation

Both words really are in the file. The recording contains acoustic information consistent with each interpretation at different frequency ranges: the cues for “Yanny” sit in the higher frequencies, the cues for “Laurel” in the lower ones. Which one your brain locks onto depends on your hearing, your playback device, the volume, and your expectation.

That last factor is why the clip is so unstable. Age-related high-frequency hearing loss makes older listeners more likely to hear “Laurel.” Cheap phone speakers roll off bass and push people toward “Yanny.” And once someone tells you which word to listen for, you can often flip it at will. Researchers described the sound as sitting on a perceptual boundary, comparable to bistable visual illusions like the Necker cube — the input never changes, but your interpretation of it can.

Pitch-shifted versions posted during the frenzy demonstrated this directly: shift the file down and almost everyone hears Yanny, shift it up and almost everyone hears Laurel.

Why it mattered

“Yanny or Laurel” is the direct audio successor to The Dress three years earlier, and it produced the same distinctive social effect. Because you cannot demonstrate what you are hearing, and because everyone assumes their senses report objective fact, the argument turns oddly personal — people genuinely suspected each other of lying.

The lasting takeaway was not the answer (the file is a recording of “laurel”). It was the demonstration that perception is reconstruction, and that two people looking at or listening to identical input can arrive at incompatible certainties. That framing outlived the meme itself and gets invoked in arguments about media, memory and eyewitness testimony to this day.
