Growing up in Indonesia, we had "Kuku kaki kakekku kayak kuku kaki kakakku" (my grandfather's toenails look like my older sibling's toenails). The repetitive k-sounds are brutal.

What's interesting is how tongue twisters reveal what's phonetically tricky in each language. English struggles with s/sh transitions ("she sells seashells"). Indonesian targets the k-cluster combinations.

Curious if there's research on whether practicing tongue twisters in a second language actually helps with accent reduction, or if it's just party tricks.

Interesting stuff! Korean 3 is different than what I remember. My version is a bit purer of a tongue twister.

들에 콩깍지 깐 콩깍지 안깐 콩깍지

Grew up in a trilingual family, learned a couple more, definitely the hardest tongue twister, by far.

I found it a lot more difficult to read any of the tongue twisters due websites color scheme. For a moment I thought there's an issue with my brain!

A lot of them seem less like tongue twisters and more like plays on homophones, for English, at least.

Here are some I remember:

Black bug's blood and red bug's blood. (Trickier than it seems - try repeating it fast many times.)

Round and round the rugged rock, the ragged rascal ran.
