Strings of phones (and phonemes) are like sheet music. You are either following the sheet music or you are ad-libbing.

You are either literally saying

[k͡xɯɭːe̞ɕiksɯkʰo̞n] 클레식 스콘

Or you are making something up.

This is how I explain “accents” to people. You do not “have an accent.” You are literally making sounds up and inserting/deleting them in places where they should not be, and you are calling it an “accent.”

Imagine if I asked you to say “hamburger” and you keep saying “whale shark.” After a certain point, you have to understand that you don’t really have an accent, you’re just refusing to replicate reality.

I apologize if that sounds harsh, but it wasn’t until I realized this that my understanding of phonetics improved immensely.
