-ㄹ수록 / -을수록 means the more..., the more... or as ... more and more.

So:

• 연습하다 = to practice
• 연습할수록 = the more you practice / as you practice more

This grammar attaches to a verb stem:

• 가다 → 갈수록 = the more one goes / as time goes on
• 보다 → 볼수록 = the more one sees
• 연습하다 → 연습할수록 = the more one practices

In this sentence, it sets up a cause-and-result pattern:

• 연습할수록 발음이 나아져요
  = The more you practice, the better your pronunciation gets.

Both can involve a condition, but they are not the same.

• 연습하면 = if you practice / when you practice
• 연습할수록 = the more you practice

So:

• 연습하면 발음이 나아져요
  = If you practice, your pronunciation improves.

• 연습할수록 발음이 나아져요
  = The more you practice, the more your pronunciation improves.

The second one emphasizes gradual increase. It is not just saying practice helps; it says improvement grows along with the amount of practice.

Because 발음 is the thing that is improving, so it is the subject of 나아지다.

• 발음이 = pronunciation + subject particle
• 나아지다 = to get better, to improve

So literally, the structure is closer to:

• Pronunciation gets better

not

• Someone improves pronunciation

If you used 발음을, that would suggest pronunciation is the object of an action verb, which does not fit 나아지다 well.

Compare:

• 발음이 나아져요 = pronunciation improves
• 발음을 고쳐요 = correct/fix pronunciation
• 발음을 연습해요 = practice pronunciation

나아져요 comes from the dictionary form 나아지다, which means to get better, to improve, or sometimes to recover depending on context.

Breakdown:

• 나아지다 = to improve / get better
• stem: 나아지-
• polite present ending: -어요
• 나아지어요 contracts to 나아져요

This kind of contraction is common in Korean.

So:

• 발음이 나아져요 = pronunciation gets better / improves

Both can sometimes be translated as to get better, but 나아지다 often sounds more natural for improvement in condition, ability, health, or quality after effort or change.

In this sentence:

• 발음이 나아져요 = your pronunciation improves

You may also hear:

• 발음이 좋아졌어요 = your pronunciation became good / has gotten better

The difference is subtle here, but:

• 나아지다 often focuses on improvement from a previous state
• 좋아지다 often focuses on becoming good/better in quality

For pronunciation, both can appear, but 나아지다 is very natural when talking about progress through practice.

Korean often leaves out subjects when they are obvious from context.

So 연습할수록 발음이 나아져요 naturally implies something like:

• the more you practice, your pronunciation improves
• or the more one practices, pronunciation improves

In English, you usually need to say you or your, but Korean often does not.

That is very normal. Korean speakers rely heavily on context.

In Korean, the present tense is often used for general truths, habits, and ongoing tendencies.

So 나아져요 here does not mean only is improving right now at this exact second. It can mean:

• improves
• gets better
• will get better as a general result

This is similar to English sentences like:

• Practice makes perfect
• The more you study, the better you get

Even though the result happens over time, the present tense is used because it expresses a general principle.

Yes. That is an excellent translation.

Other natural translations include:

• The more you practice, the better your pronunciation gets.
• Your pronunciation improves the more you practice.
• As you practice more, your pronunciation gets better.

They all capture the meaning well.

Yes. 연습하다 can mean simply to practice when the object is understood from context.

So if you are already talking about speaking Korean or pronunciation, 연습하다 by itself is perfectly natural.

If you want to be more specific, you could say:

• 발음을 연습할수록 나아져요 — less natural as written because what improves is less clear
• 발음을 연습할수록 발음이 나아져요 — grammatical, but repetitive
• 한국어를 연습할수록 발음이 나아져요 = the more you practice Korean, the better your pronunciation gets

The original sentence sounds natural because the context probably already makes the object of practice clear.

A natural approximate pronunciation is:

• 연습할수록 → 연스팔수록
• 발음이 → 바르미
• 나아져요 → 나아저요 or very smoothly 나아져요

A few pronunciation notes:

• In 연습, the ㅂ is not strongly pronounced as a separate p sound in slow, careful English-style pronunciation. In connected speech, it often sounds closer to 연습 → 연습 / 연습 with the following sound making it feel like 연스...
• 발음이 is commonly pronounced as 바르미 because of sound changes in connected speech
• 져요 sounds like 저요 blended smoothly

You do not need to overthink every sound rule at first, but it is good to know that the spoken form may sound a little different from the spelling.

Yes, you can, but 연습할수록 is more compact and natural in many situations.

Compare:

• 연습할수록 발음이 나아져요
• 연습을 할수록 발음이 나아져요

Both are understandable. The first is usually smoother because 연습하다 is commonly treated as one verb.

Korean often does this with noun + 하다 verbs:

• 공부하다 = to study
• 운동하다 = to exercise
• 연습하다 = to practice

So using 연습할수록 is the standard and most natural form.

Yes. 나아져요 is in the polite informal style, which is one of the most common everyday speech levels in Korean.

So the sentence is polite and natural for normal conversation:

• 연습할수록 발음이 나아져요

If you changed the speech level:

• 연습할수록 발음이 나아진다 = plain style, often used in writing, explanation, or self-talk
• 연습할수록 발음이 나아집니다 = formal polite style

The meaning stays the same; only the level of politeness and formality changes.
