You know the Hangul letters, which is a huge step. Now, let's make them sound right. Korean pronunciation might seem tricky at first, but it's more consistent than English. Once you get the hang of a few key ideas, you can pronounce most words you see.

Many Korean consonants come in sets of three: a plain version, an airy version, and a tense version. Think of them as different levels of intensity for the same basic sound.

Let's start with the G/K sounds: ㄱ, ㅋ, and ㄲ.

• ㄱ (g/k): This is the plain, unaspirated sound. At the beginning of a word, it sounds like a soft 'g' (as in 'go'). Between two vowels, it sounds more like a 'k'. There's no strong puff of air.
• ㅋ (k): This is the aspirated version. Imagine the 'k' in 'key' and exaggerate the puff of air that comes out. You should be able to feel it on your hand if you hold it in front of your mouth.
• ㄲ (kk): This is the tense sound. There is no puff of air at all. The muscles in your throat tighten up to make a sharp, clipped sound, like the 'k' in 'sky'.

The same pattern applies to other consonant groups. For the D/T sounds:

• ㄷ (d/t): Plain, like a soft 'd' or 't'.
• ㅌ (t): Aspirated, with a strong puff of air.
• ㄸ (tt): Tense, a sharp sound like the 't' in 'stop'.

And for the B/P sounds:

• ㅂ (b/p): Plain, like a soft 'b' or 'p'.
• ㅍ (p): Aspirated, like a windy 'p'.
• ㅉ (pp): Tense, a sharp 'p' sound like in 'spy'.

Finally, the S and J sounds follow a similar, though slightly different, pattern.

• ㅅ (s): A standard 's' sound, like in 'sea'. However, when it comes before the vowel ㅣ (i), it sounds like 'sh'. So, 시 is pronounced 'shi'.
• ㅆ (ss): The tense version. It’s a sharper 's' sound, like the 'ss' in 'hiss'.
• ㅈ (j): A plain 'j' sound, as in 'jump'.
• ㅊ (ch): An aspirated 'ch' sound, like in 'chair'.
• ㅉ (jj): The tense 'j', with no air. It sounds like the 'dg' in 'judge' but sharper.

Korean vowels are generally straightforward, as they each have one consistent sound. The basic vowels are ㅏ (a), ㅓ (eo), ㅗ (o), ㅜ (u), ㅡ (eu), and ㅣ (i).

The sound for ㅓ ('eo') can be tricky. It's similar to the 'o' in 'song', but with your mouth a bit more open and relaxed. The vowel ㅡ ('eu') is also unique. To make this sound, say 'ooh' but spread your lips wide into a flat line, almost like a grimace.

Diphthongs are combinations of two vowel sounds. They look more complex but are just blends of the basic vowels you already know. For example:

• ㅑ (ya) is just ㅣ (i) + ㅏ (a)
• ㅕ (yeo) is ㅣ (i) + ㅓ (eo)
• ㅘ (wa) is ㅗ (o) + ㅏ (a)
• ㅝ (wo) is ㅜ (u) + ㅓ (eo)
• ㅢ (ui) is ㅡ (eu) + ㅣ (i)

For ㅢ, the pronunciation can change. At the start of a word, it's 'ui'. In the middle of a word, it often sounds like 'i'. When it's used as a possessive particle (meaning 'of'), it's pronounced 'e'.

Just a few simple rules will make your Korean sound much more natural. The most important one involves the final consonant of a syllable, known as the batchim (받침).

When a syllable with a final consonant is followed by a syllable that starts with a vowel (specifically, the silent consonant ㅇ), the final consonant's sound 'moves over' to the beginning of the next syllable. This makes the words flow together smoothly.

Consider the word for 'Korean language', 한국어.

Broken down, it's 한 (han) + 국 (guk) + 어 (eo). Instead of saying 'han-guk-eo' with a hard stop, the 'ㄱ' sound from 국 moves to the start of 어. The result is a pronunciation that sounds like 'han-gu-geo'.

Another key rule is nasalization. Certain final consonants change their sound when they are followed by a nasal consonant like ㄴ (n) or ㅁ (m).

For example, the final consonants ㅂ, ㄷ, and ㄱ often change to ㅁ, ㄴ, and ㅇ (ng) respectively.

The word 입니다 (imnida), meaning 'to be', is a perfect example. It's written as 'ib-ni-da', but the 'ㅂ' sound before the 'ㄴ' changes to an 'ㅁ' sound, making the pronunciation 'im-ni-da'.

Getting these sounds right takes practice. Listen to native speakers as much as you can and try to mimic the sounds. Recording yourself can also be a huge help.
