Korean Phonology and Hangul

I've literally being dying to write this blog. Some topics get me very excited, but not many get me more excited than phonetics and phonology.  Anyway, I wanted to make sure I got my stuff mostly right before posting. So what's all the fuss about then? Well it's Hangul that's what, and thanks to Sunny (선휘), my new Korean friend I reckon I've pretty well got it sussed.

Hangul is the writing system used for the Korean language. What got me interested is not only that it almost perfectly phonemic, but that the letters (jamo) are arranged into syllables! I had never seen this before.. I'd never even thought this before. For example, my name in Hangul is arranged into the two syllables 러자.

Okay, okay. First things first. Let's have a look at the individual jamo which make up each syllable. There are 24 characters in total, each one representing just one or two phonemes or dipthongs. First, the 14 consonants:

Korean Phonology and Hangul


glyph sounds name glyph sounds name
[g], [k] 기역 [gijɑk] [kʰ] 키읔 [kʰiɯk]
[n] 니은 [niɯn]        
[d], [t] 디귿 [digɯt] [tʰ] 티읕 [tʰiɯt]
[r], [l] 리을 [riɯl]        
[m] 미음 [miɯm]        
[b], [p] 비읍 [biɯp] [pʰ] 피읖 [pʰɯp]
[s], [ʃ] 시옷 [ʃiot]        
[ŋ] 이응 [iɯŋ] [h] 히읗 [hiɯt]
[tʃ], [dʒ] 지윽 [jiɯt] [tʃʰ] 치읓 [tʃʰiɯt]

There are also five tensed consonants: ㄲ, ㄸ, ㅃ, ㅆ and ㅉ.

But really the consonants don't interest me all that much. All those sounds can be found in English so it's not all that new. The vowels are (as always), much more difficult. It's taken me a long time to figure out, but I'm starting to get the hang of it. I have four different references for Korean vowels - two articles I found online, a CD I bought from the bookshop, and a recording of Sunny saying the vowels. Here are the vowel sounds as best I could make out from these sources:


  a1 a2 cd sun   a1 a2 cd sun   a1 a2 cd sun
[a] [a] [a] [a] [ja] [ja] [ja] [ja] [wa] [wa] [wa] [wa]
[ʌ] [ə] [ɑ] [ɑ] [jʌ] [jə] [jɑ] [jɑ] [wʌ] [wə] [wʌ] [wɑ]
[o] [o] [o] [o] [jo] [jo] [jo] [jo] [ø] [ö] [ø] [wɛ]
[u] [u] [u] [u] [ju] [ju] [ju] [ju] [wi] [ü] [wi] [wi]
[ɯ] [ũ] [ɯ] [ɯ]           [ɯi] [ũi] [ɯi] [ɯi]
[i] [i] [i] [i]                    
[ɛ] [æ] [ɛ] [ɛ] [je] [jæ] [jæ] [ɛ] [wɛ] [wæ] [we] [wɛ]
[e] [e] [ɛ] [ɛ] [jɛ] [je] [jɛ] [jɛ] [we] [we] [wɛ] [wɛ]

I have most difficulty with ㅐ and ㅔ, and ㅒ and ㅖ. Also I sometimes get ㄹ and ㄷ mixed up. It seems that for the Korean [r] your tongue must touch the roof of your mouth, which is why I sometimes hear [d]. I can't find the exact sound in IPA, but hopefully I have I'll be able to make some YouTube videos from Sunny's recording soon and post them here.

Hi Roger,

That 'r' sound you're talking about is a flap.  If you stop thinking about it as an 'r', you'll be onto a good start in producing it.

Check out: http://en.wikipedia.org/wiki/Flap_consonant. 

Also note that the ㄹ is realized as an [l] syllable final before a consonant (except for [h]), or in the environment of another [l].
