interpretation by the brain, says Brad Story, a professor of speech, language and hearing sciences at the University of Arizona. Primary information that would be present in a high-quality recording or in person is “weakened or attenuated,” Story says, even as the brain is eagerly looking for patterns to interpret.
“And if you throw things off a little bit, in terms of it being somewhat unnatural, then it is possible to fool that perceptual system and our interpretation of it,” says Story.
According to Ben Munson, University of Minnesota professor language professors says that the discrepancy in what people hear comes down to a few different possibilities, none of which sort it out for certain. He also says that one cause of its trickiness is that the sound file is synthesized, which is different than real speech.
Others have theorized that the different sounds are caused by the actual the consonants in “Yanny” and “Laurel.” The “y,” “n,” “l” and “r” sounds are really the chameleons of speech. The way one pronounces them morphs based on the sounds that come before and after them in a word. Because of this, it is the brain of the listener that decides their identity, based on context. In this case, the sound is missing a few elements and your brain automatically makes a judgment, called interpolation, similar to how you can so easily read partially erased text.
Either way, let’s hope we don’t have to endure another internet battle of the wits anytime soon. I don’t think our brains can handle it.
