Some pronounciation questions~
So far I know that;

When ᄀ, ᄁ, or ᄏ are beside ᄆ or ᄂ, then ᄀ\ᄁ\ᄏ sounds like ᄋ
When ᄇ or ᄑ are beside ᄂ or ᄆ, then ᄇ\ᄑ sounds likeᄆ
When ᄃ, ᄐ, ᄉ, ᄊ, ᄎ, or ᄌ are beside ᄂ or ᄆ the sound like ᄂ
When ᄂ is on either side of ᄅ, ᄂ becomes ᄅ
and when ᄅ is beside any constanant (except ᄂ) it sounds like ᄂ

What I wanna know is: Am I missing\forgetting any? Or are these pretty much it?

Also, in my "Basic Korean" book it tells me that:
The word 강남역 sounds like 감남녁
The word 앞유리 sounds like 암유리
And that the word 하릇밤 sounds like 하릎밤..
Is it correct? If so, why?
I also notice that in alot of ᄑ/ᄇ+유 words like 십육 the ᄑ/ᄇ sounds likeᄆ. Why is this? I'm sooo confused o

Answer

I searched internet about  Korean pronounce 

앞유리[암유리(x) 압유리(o)] in that case
제9항  받침 'ㄲ, ㅋ', 'ㅅ, ㅆ, ㅈ, ㅊ, ㅌ', 'ㅍ'은 어말 또는 자음 앞에서 
      각각 대표음 [ㄱ, ㄷ, ㅂ]으로 발음한다.
      닦다[닥따]      키읔[키윽]      키읔과[키윽꽈]      옷[오ㄷ]
      웃다[우ㄷ:따]   있다[이ㄷ따]    젖[저ㄷ]            빚다[비ㄷ따]
      꽃[꼬ㄷ]        쫓다[쪼ㄷ따]    솥[소ㄷ]            뱉다[배ㄷ:따]
      앞[압]          덮다[덥따]
 and  
하룻밤[하릎밤] is incorrect becoz our pronounce just have "ㄱ ㄴ ㄷ ㄹ ㅁ ㅂ ㅇ"
  I think  하룻밤[하루빰 or 하룯빰] is correct pronouce 

강남역 십육 are very hard to explain.. becoz korean pronouce has a lot of irregular form  if I find pronouce rule  I'll teach you!!

Answer

Hi ^^
well... I think it is hard to us too because usually we don't think the pronounciation like that.
and as i know (only my idea) we pronounciate 강남역 ->강남녁, 앞유리 ->압유리, 암유리
you'de better have speaking exercises with korean on the skype or other massinger.

I always think you are the best student :)
