anyone know anything about it ?
Is it true that wearing a tongue piercing/ring helps pronunciation to become better?
I had three children who all wore tongue studs (ear, eyebrow, nose and lip rings...not all at the same time, thank God).
Wearing a tongue stud never helped any of them speak any clearer English.
Wildly unlikely (though, perhaps, it doesn't make the pronunciation worse). Since the typical standard for "good" pronunciation is "The way most (educated) people speak and, since most people do not have tongue piercings, it's very hard to see how having a piercing could make one sound more like the people who don't.
