Apparently that's the common English pronunciation of the town. I learned it pronounced as "SEE all" years ago , but recently I've been told that's wrong too.
I really wish Duolingo had a better text to speech program. It's Korean pronunciation is noticeably bad even to people who don't natively speak Korean.
What?I mean why to report?Duo is only teaching us how koreans pronounce it!! it isn't always pronounced how it's written..do we pronounce all the words just how it's written in English?then why do yoy expect it in korean??!! Koreans pronounce seoul as saur;l and london as dondon.. You should watch kdramas to get familiar with korean accent!! Is Duo blamed for helping us with korean accent??!!
