Don't know if you'd heard about this (probably you have---everyone is talking about it) but there is a crazy synthesized speech where people hear different words!
What word do you guys hear?:

My mom and I hear 'Yanny' but my sister and dad hear 'Laurel'!
Anyway, to make a long story short[ish] one version of what happened is that a synthesized dictionary audio tool (the type that speaks for blind people or who just want to hear how to pronounce a word) was played over a loudspeaker at a school, for the word 'laurel' and the kids who all listened-----half heard 'Yanny' and the other half heard 'Laurel'!
Another story is that the clip was initially posted online by a high school student who needed to learn the definition of laurel, so she searched for the word on Vocabulary.com, but when she played the pronunciation recording, she thought she was hearing "yanny."
Not sure which is the true orginator of this.
But certainly a student named Cloe Feldman posted it on her social media account 2 days ago as 'what do you hear?' and it's just exploded over everywhere since!
The scientists and audiologists say both are correct and that the 'fake' voice could be interpreted by human brains EITHER way, depending on if we focus on the low frequencies or high frequencies!
This site below lets you move the frequency until you hear the opposite. I hear 'Yanny' so I had to go 3/4 to the left (lower) until I could hear 'Laurel'. For my sis, I had to slide the switch 3/4 to the right (higher) for her to even hear 'Yanny' at all and even so she said it sounded more like 'Yally' and it hurt her ears.
Here's the tool:

But as it is, with the either/or frequency, it really could be either! The scientists say there is no 'wrong' answer, just how one's brain interprets the frequencies. Wow, huh? Sort of like those pictures where you can see a vase or 2 faces; or an old lady or young lady? Both are there, just how you see it.
