[kyllo]

Which pronunciation of Seoul is it like? The way Koreans pronounce it? The way Americans pronounce it? The way Europeans pronounce it?

I'm confused because Seoul doesn't have an 'e' sound in it at all, in Korean.

[agumonkey]

Is the 'e' skipped [soul] ? almost silent [s_oul] ? or a transition like [s~woul] ?

ps: forgot about https://translate.google.com/#en/ko/seoul, according to them it's not entirely silent.

어 (transliterated as either "eo" or "uh") is a vowel that I would describe as like the "u" sound in the word "fun" but with the mouth open a bit wider.

It's nothing like any of the sounds an "e" can represent in English.

Europeans tend to pronounce it "See-OOL" which is just completely wrong.

It's a bit longer, always morphemic version of a schwa I believe.

In International Phonetic Alphabet it's [sʰʌ.ul].

The vowel ʌ is described as "between pearl and pull, with spread lips"
