[Character] ㅗ [Sound] O [Notes] This is another "o" sound. They sound very similar. The best I can do is say this may be more like the other side of saying O, as with the experiment before. The part toward the end in O is more like this. Or, think of it this way. ㅗ is like the 'o' in go, row, bow, and low. They are very similar. Some people will be able to hear the difference if they have a good ear. Many non native speakers have the problem hearing the difference though at first. So, for those who cannot hear the difference, When spelling and learning Korean, try to think of these are learning to spell. In English you can't always know how to spell a word, you must learn it properly. It is the same way in Korean. When words with an O sound comes up, just learn how it is spelled and leave it at that because they sound so similar. This vowel will always appear underneath the first consonant, never to the right of it. [Consonant/Vowel]
