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

So:

• 연습할수록 = the more you practice / as you practice more
• 발음이 좋아져요 = your pronunciation gets better

A very literal structure is:

• 연습하다 = to practice
• 연습할수록 = the more one practices

This grammar is often used to show that one change increases along with another:

• 보면 볼수록 재미있어요. = The more I watch it, the more interesting it is.
• 공부할수록 어려워요. = The more I study, the harder it gets.

The dictionary form is 연습하다. To make -ㄹ수록, you attach it to the verb stem.

Here is the breakdown:

• 연습하다
• verb stem: 연습하-
• add -ㄹ수록
• 연습할수록

Because the stem ends in a vowel, you use -ㄹ수록.

Compare:

• 가다 → 갈수록 = the more one goes / as time goes on
• 먹다 → 먹을수록 = the more one eats

So 연습할수록 is just the regular form built from 연습하다.

Because 발음 is the thing that is getting better, so it functions as the subject of 좋아지다.

• 발음이 좋아져요 = pronunciation gets better

With 좋아지다, the thing that changes usually takes 이/가.

Compare:

• 날씨가 좋아져요. = The weather gets better.
• 기분이 좋아졌어요. = My mood improved.

If you used 발음을, that would suggest pronunciation is the object of another verb, which is not what is happening here.

This is a very important difference.

• 좋아요 = is good
• 좋아져요 = becomes good / gets better

So:

• 발음이 좋아요 = The pronunciation is good.
• 발음이 좋아져요 = The pronunciation improves / gets better.

In your sentence, the point is not just that the pronunciation is good now, but that it changes in a positive direction as practice increases.

It comes from 좋아지다, which means to become good or to improve.

Breakdown:

• 좋다 = to be good
• 좋아지다 = to become good, to get better
• 좋아져요 = polite present form of 좋아지다

The 아/어지다 pattern is very common for becoming something:

• 커지다 = to become big
• 작아지다 = to become small
• 빨라지다 = to become fast
• 좋아지다 = to become good / improve

So 발음이 좋아져요 literally means pronunciation becomes good.

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

So this sentence can naturally mean:

• The more you practice, your pronunciation gets better.
• The more I practice, my pronunciation gets better.
• The more one practices, pronunciation gets better.

In real conversation, the listener usually understands whose pronunciation is being discussed from context.

If you wanted to make it explicit, you could say:

• 연습할수록 제 발음이 좋아져요. = The more I practice, my pronunciation gets better.
• 연습할수록 발음이 좋아져요. = The more you/I practice, pronunciation gets better.

Yes. 연습하면 할수록 is a very common and natural alternative.

Both mean roughly:

• the more you practice, the better your pronunciation gets

The difference is mostly style and emphasis:

• 연습할수록 = slightly more compact
• 연습하면 할수록 = very common in speech, often feels a bit more emphatic or explicit

Examples:

• 읽을수록 재미있어요.
• 읽으면 읽을수록 재미있어요.

Both mean The more I read it, the more interesting it is.

Not exactly.

연습할수록 does not simply mean while practicing. It means as practice increases or the more one practices.

So it expresses a correlation between two changes:

• more practice
• better pronunciation

If you wanted to say while practicing, you would use a different structure, such as:

• 연습하면서 = while practicing

Compare:

• 연습하면서 발음을 들었어요. = I listened to the pronunciation while practicing.
• 연습할수록 발음이 좋아져요. = The more I practice, the better my pronunciation gets.

좋아져요 is in the standard polite style, which is very common in everyday Korean.

Levels here:

• 좋아져요 = polite, natural, everyday
• 좋아진다 = plain style, often used in writing, explanation, or casual speech
• 좋아집니다 = formal polite

So you might also see:

• 연습할수록 발음이 좋아진다.
• 연습할수록 발음이 좋아집니다.

All are grammatically fine; the difference is mainly politeness and style.

Yes, to some extent. Korean word order is flexible, especially when particles make the roles clear.

The most neutral version is:

• 연습할수록 발음이 좋아져요.

You could also hear:

• 발음이 연습할수록 좋아져요.

But the original order sounds more natural because it presents the condition/trend first and then the result.

So for learners, the best pattern to remember is:

• Verb + -ㄹ/을수록 + subject + change/result

Example pattern:

• 공부할수록 실력이 늘어요. = The more you study, the more your skills improve.

Yes. 발음 means pronunciation, and in this sentence it refers to pronunciation ability or quality in a general sense.

So 발음이 좋아져요 can mean:

• your pronunciation becomes clearer
• your pronunciation improves
• your pronunciation gets better

It does not have to refer to just one sound or one word. It can describe overall pronunciation ability.

Very natural related expressions are:

• 발음이 좋아요. = Your pronunciation is good.
• 발음이 많이 좋아졌어요. = Your pronunciation improved a lot.
• 한국어 발음이 좋아졌어요. = My Korean pronunciation improved.
