My experience is the same as Adli’s - all I can hear is ‘laurel’ in the original recording.
From the article: They speculate that there are two separate voices in the recording, one saying “Laurel” at a lower frequency and the other saying “Yanny” at a higher frequency. If you play the recording at a frequency with more bass, you’re probably more likely to hear “Laurel,” while if the there is less bass, you’ll hear “Yanny.”
So apparently it is a trick of sorts, and with the two lowered-pitch recordings I very clearly hear ‘yammy’(definitely M sound). The raised pitch recordings sound to me like chipmunks saying ‘laurel’. The link to Chloe Feldman doesn’t work for me, and I’d love to know where to apply for the job of Influencer :)
