Tongue twisters: Terribly terrific and truly tantalizing

Why is it so hard to say sentences like: she sells sea shells at the sea shore? This episode cracks the code of tongue twisters. Check out the role mouth shapes and vocal folds play in tongue twisters. Stefanie Shattuck-Hufnagel will share her research into tongue twisters and how she came up with some of the hardest sentences for people to say. We also have a report on “the late eight,” a group of sounds that can be tough to say — and quite confounding when combined. Also, be sure to check out our listener-submitted tongue twisters — some you may have heard before, others are brand new to the world! Stick around for a stumper of a Mystery Sound too!
