Speaker of the US House of Representatives Paul Ryan has weighed in on the Yanny vs Laurel debate.
The auditory illusion has divided the internet with people hearing either "Laurel" or "Yanny".
Unprompted, Paul Ryan settled the latest controversy, "I'd like to declare something that is just so obvious: It is Laurel and not Yanny."
- The truth behind the Yanny/Laurel mystery
- Yanny or Laurel? The audio clip which has the internet divided
The New York Times tracked down the original source of the auditory meme to Roland Szabo, an 18-year-old student from Georgia, who found the clip on website vocabulary.com. He posted it on web forum Reddit, and it spread online from there.
People more perceptible to high-frequency sounds are more likely to hear 'Yanny' whereas 'Laurel' is what those accustomed to low-frequencies hear.
The speaker took a vote of 'Laurel' fans at a news conference in the Capitol to find who was in the same camp.
While visual illusions like the white and gold (or blue and black) dress have become common, this is arguably the first auditory illusion to stump the internet.
