The Korean consonant is usually taught as an "h" sound. That is a good starting point:
하 = ha
호 = ho
한국 = Han-guk
But in real Korean speech, does not always sound as strong as English "h." Sometimes it becomes very soft. Sometimes it affects the consonant next to it. Sometimes you may barely hear it at all.
This does not mean Korean speakers are being unclear. It means ㅎ has special pronunciation behavior, especially in connected speech. Your goal is simple: know what to expect when listening and avoid over-pronouncing every ㅎ like a heavy English "h."

Pattern 1: ㅎ at the beginning is usually clear

At the beginning of a word or syllable, is often easy to hear.
Korean
Rough sound
Meaning
하나
ha-na
one
한국
han-guk
Korea
회사
hoe-sa
company
하루
ha-ru
one day
Beginners should pronounce these with a light Korean h, not a very strong breathy English sound. Korean is usually cleaner and shorter than a dramatic "ha!" in English.
Keep the present, but relaxed: 한국어를 공부해요, 회사에 가요.

Real Moment: Hearing 좋아요 in Fast Speech

A Korean friend recommends a restaurant and says, 여기 좋아요. In your textbook brain, you expect a clear 조-하-요. In real speech, it may sound closer to 조아요. Do not panic. The word did not change; the simply became light between vowel sounds.
Now compare it with 좋다. This often sounds like 조타, because the ㅎ affects the next consonant. So the same written ㅎ can feel soft in 좋아요 but strong through the next sound in 좋다. Listening for this pattern helps real Korean sound less mysterious.

Pattern 2: ㅎ can become weak between vowels

When appears between vowel sounds, many speakers pronounce it softly. You may hear only a light breath, or in fast speech it may feel almost hidden.
Written
Careful sound
Fast/natural feeling
좋아요
jo-ha-yo
jo-a-yo-ish
많아요
ma-na-yo-ish
connected and light
넣어요
neo-heo-yo
neo-eo-yo-ish
싫어요
si-reo-yo-ish
affected by ㅀ sound change
The important listening point is this:
In connected speech, ㅎ may be much softer than you expect.
A very common example is 좋아요. In careful speech, you can hear 조하요. In everyday speech, it often sounds closer to 조아요.
For speaking, you do not need to delete the sound on purpose. Just avoid making it too strong.

Pattern 3: ㅎ can make the next consonant sound stronger

When meets certain consonants, it can combine with them and create a stronger, aspirated sound. This is why some written forms do not sound exactly as beginners expect.

Natural sound idea
Why
좋다
조타
ㅎ + ㄷ → ㅌ sound
많다
만타
ㅎ + ㄷ → ㅌ sound
놓고
노코
ㅎ + ㄱ → ㅋ sound
이렇게
이러케
ㅎ affects ㄱ in 게/게-like sequence
This is not random. Korean has a sound pattern where ㅎ adds aspiration to nearby plain consonants like ㄱ, ㄷ, ㅈ in certain positions.
Beginner translation: the h-breath can move onto the next consonant.
So:
좋다 is not usually pronounced "joh-da." It sounds closer to 조타.
많다 is not "manh-da." It sounds closer to 만타.
놓고 is not "noh-go." It sounds closer to 노코.

Be careful: not every ㅎ disappears

It is tempting to say "ㅎ disappears in Korean." That is too broad and can create bad pronunciation habits.
In many places, ㅎ is clearly pronounced:
하늘 = sky
호텔 = hotel
호랑이 = tiger
행복 = happiness
In other places, ㅎ changes nearby sounds rather than simply disappearing:
좋다 → 조타
많다 → 만타
놓고 → 노코
And in fast speech between vowels, ㅎ may be softened:
좋아요 → sounds like 조아요-ish
So a better beginner rule is:
ㅎ is a light, flexible consonant. It can be clear, soft, or absorbed into a nearby consonant depending on its position.

Listening examples you will hear often

Korean phrase
What learners may expect

좋아요
jo-ha-yo
jo-a-yo-ish
좋죠
joh-jyo
조쵸-ish
괜찮아요
gwaen-chanh-a-yo
괜차나요-ish
많죠

The "-ish" spellings are not official romanization. They are listening hints for beginners. Korean pronunciation is better learned through sound, not English letters.

Speaking tip: keep it light

If your first language is English, you may push too much air on "h." Say Korean with less air, then say 좋아요 slowly: 조-하-요. Next, say it naturally: 조아요-ish, but do not force-delete the ㅎ. The goal is relaxed speech, not lazy speech.

Teacher practice

Practice in three rounds.

Round 1: Clear ㅎ

Say these with a light but clear :
Korean
Meaning
하늘
sky
회사
company
한국어
Korean language
행복해요
I'm happy

Round 2: ㅎ affects the next consonant

Read the written form, then say the natural sound target.
Written
Say it like
좋다
조타
많다
만타
놓고
노코
좋고
조코

Round 3: Soft ㅎ in common speech

Say these slowly first, then naturally.
Korean
Slow practice
Natural listening target
좋아요
조하요
조아요-ish
괜찮아요
괜찮아요
괜차나요-ish
넣어요
너허요
너어요-ish
Do not worry if your pronunciation is not perfect immediately. The first win is hearing that Korean is not always a strong English-style "h."

Final takeaway

Korean is usually clear at the beginning of words, soft between vowel sounds, and powerful when it combines with nearby consonants. It can make ㄱ, ㄷ, or ㅈ sound more aspirated in common patterns, as in 좋다 → 조타 and 놓고 → 노코.
For beginner speaking, pronounce lightly. For beginner listening, expect it to sometimes sound softer than the spelling suggests. That one adjustment will make real Korean speech feel much less surprising.
