Book Introduction
"Can you speak English roughly?"

This is the question I've heard most often since I created the "Rough English" program 10 years ago.
Then I smile and answer like this.

"Yes, English is originally a rough language.
Learn to have fun, every day, roughly.

I've liked English since middle school.
But sitting at a desk, memorizing grammar and solving problems was stiff and boring.
'I have to study anyway, so can't I make it a little easier and more fun?' That question was always on my mind.
So, like a frog, I jumped out of the textbook.
I read English novels for six hours a day, imitated movie lines, and sang along to song lyrics, believing that "English is not a study, but a game."


Thanks to that, I was more confident in English than anyone else, and curious about the wider world of language, I went on to study Chinese Literature at Seoul National University.
Then, during the period when diplomatic relations between Korea and China were established, I became a civil servant through special recruitment in Chinese and worked as a diplomat in Hong Kong and Beijing.
Although I always worked in English, I felt the 'English wall'.
I couldn't hear the rapid conversations between my foreign colleagues clearly.
"Can't I listen to fast English? Can't I just open my ears to English?"

From this time on, I started to think seriously about ‘listening.’
And finally, I came across a method called 'English Speed ​​Listening'.
In just one month, I had the miraculous experience of being able to listen to all the news in English and solving the difficult TOEIC listening problem.
Since then, I have had a desire to share this experience with countless young people and students.
That was the beginning of the current 'rough English' learning method.

Into the book
The word 'roughly' does not mean laziness, but rather an attitude of letting go of unnecessary perfectionism and focusing on the essence.
The author found true joy in experiencing English outside of textbooks, and transformed the frustration of rote learning into new energy for learning.
As I delved into something I loved, a dreamlike opportunity came my way, and when I was faced with the crisis of not being able to understand English even after becoming a diplomat, I came across 'Speed ​​Listening English'.
Through the experiences of those around me, I became convinced of the effectiveness of listening, and reached a turning point where I moved forward with a new mission.
Furthermore, you will realize that learning through listening to Korean words can be surprisingly effective in learning English.

English, why should you do it roughly?

In Silicon Valley, imperfect English, or so-called "Broken English," is the basis of communication.
But why do Koreans struggle to master English despite decades of investment? The case of an American program that cured dyslexia in just four weeks, and the reality that even Seoul National University English Department students struggle to converse in English, highlight the problems inherent in Korean English education.
The truth that repeating key vocabulary is more important than parroting, and the example of Finland, where English is spoken 'haphazardly' and with enjoyment, provides us with profound insight.
In this global trend, the “Daecheong English” program, developed as a Korean solution, appears.
--- 「PART 2.
The world is already in the era of rough English!

English should be a tool to tell my story, not something to memorize.
Listening to Korean quickly opens your ears to English, shadowing at 4x speed awakens your brain, and learning with enjoyment rather than striving for perfection releases dopamine.
Actual students leave miraculous reviews such as, “I solved my lifelong struggle with English,” “I found my youth again through English,” and “I changed from ‘Can I do it?’ to ‘Yes, I can do it.’”
This experience highlights that change is possible for anyone.
--- 「PART 3.
From the 3 principles of rough English: be rough, don't memorize, be brief

Korea has a historically strong national background that makes it difficult to speak English well.
The importance of forming a 'native ear' at 12 months of age, the ability to block out foreign language sounds, and easy English input (comprehensible input) is supported by brain science research.
In particular, the power of fast listening, which has been clinically proven by neuroscientists, leads not only to learning effects but also to improved brain function and potential development.
It also turns out that the keys to achieving optimal English condition lie in sleep, rest, and immersion.
--- 「PART 4.
From "Learning English in Rough Terms Proven by Brain Science and History"

〈Rough English〉 starts with high-frequency words that account for 80% of everyday conversation.
Based on 50 key words that open your English ears, we design a process for the brain to recognize patterns on its own.
The 30-day short-term project roadmap begins with preparation, rapid listening study, speed shadowing, intensive training, and performance verification. The long-term project culminates in simultaneous listening and speaking training, strengthening reading and speaking muscles, phonetic composition, and a one-minute speech.
At the end of it all lies the true goal of English independence, that is, bringing English into everyday life.
--- 「PART 5.
From "30 Days of Practical Training, Time to Open Your Ears"

The problem of 'garbage noise', that is, MP3 compressed audio that puts children's brains to sleep, has now become a hot topic in education.
It has been scientifically proven that sound lost during the compression process has a negative effect on the brain, while lossless sound sources, on the other hand, awaken the brain and enhance learning ability.
Therefore, the message is emphasized that in order to protect our children's English ears and brain health, we must stop listening to MP3 audio sources and create a brain-friendly sound environment.

The environment in which you listen to English determines your learning.

Publisher's Review
A diplomat who doesn't speak English

I never doubted that English was my weapon.
During my time at Seoul National University, I spoke English better than anyone else, earned some extra money through tutoring, and always shined thanks to my English.
Language also supported me during my diplomatic career in Hong Kong and Beijing, and I prided myself on being a "language-armed person."

Then one day, something unforgettable happened.
It was after a meeting with friends from the German embassy that we ended up having dinner together.
As always, the meeting went smoothly without a hitch.
The English spoken in the meeting was not difficult because it was spoken slowly and clearly.
The problem was after that.

As we moved to the dining table, two German diplomats began to have a quick conversation in front of us.
The conversation was exchanged at such a speed and intonation that it was difficult to tell whether it was business talk or a personal joke.
I froze for a moment.
I couldn't understand a single word.
The shock was indescribable.
Even at Seoul National University, I was better at English than anyone else, and I was always recognized for it, and it was thanks to it that I was able to shine. But I was completely unable to understand the natural conversations between native speakers.

"Why can I speak English in meetings, but can't speak English fluently in everyday conversation?"
'What English have I been learning so far?'
At that moment, I felt the wall of English with my whole body.

The same thing happened when watching movies or media.
Subtitles were always needed.
I hesitated for a while about whether or not to turn on the subtitles, but in the end I couldn't help but turn them on.
English was something I loved more than anyone else and was confident in, but it remained a constant source of thirst for me and a homework I could never completely overcome.

My first encounter with English in a time of crisis

At a time when my thirst for listening to English was at its peak, I had no trouble conversing in English for work, but I couldn't listen to English spoken at a native speaker's speed, such as on the news, American TV programs, or CNN.
It was a time when I was constantly looking at good books and looking for something to study that would keep me from getting bored and help me improve my current English skills.
Around that time, I happened to learn about a program called 'Speed ​​Listening English', and after much deliberation, I ended up spending a considerable amount of money, 450,000 won, to purchase it.
This is the second time I've invested a significant amount of money in my English studies, after purchasing the English 900 tapes.

It was a program that consisted of three CDs and three thin books, simply listening to English conversations at double, triple, and quadruple speed.
It looked a bit flimsy on the outside, but I had a gut feeling that 'this might be the one that pierces my ears.'
In the end, I think I decided to buy it with the mindset of 'I'll know once I try'.
At that time, I was a beginner driver, so I practiced listening in the car every morning while going to work early.
I turned on the English traffic broadcast on 〈FM 101.3MHz〉 and practiced speaking English quickly for 30 minutes to an hour.
At 7 a.m., when the English news came on, I could still only hear a few words, and the content was barely understandable.
But one day, something unbelievable happened.
One by one, the sentences from the news I always heard entered my ears.

It started coming in, and at first I thought it was a coincidence.
The moment I arrived at the company and started solving Hackers TOEIC listening problems in the English study group, I was certain that my blocked hearing had been cleared.
As the text entered my ears, the sentence structure and meaning were organized in my head as if I was reading it with my eyes.
The sentences in TOEIC LC options 1, 2, 3, and 4 were automatically connected in content, and I had the amazing experience of reading through sound.
In just one month since I started learning English through listening, I've experienced amazing changes, such as being able to hear English news and simultaneously connect listening and reading comprehension.

The shock of that time changed the direction of my life.
And with this single thought in mind, 'If everyone could have this experience, they wouldn't have to study so hard,' I embarked on a path to study English education and language education.
The emotion and conviction of that day still motivates me to this day.

Be rough, don't memorize, be brief

Just do it roughly.
There are many people who try to perfect their English but never manage to do so in this lifetime.
The 'do it roughly' that 'roughly English' talks about does not mean to do it lazily.
Let go of the weight of perfectionism and just get started.
It doesn't matter if you come across unfamiliar words or if your grammar is wrong.
Simply throwing yourself into the flowing rhythm of English is the first step to developing a sense of English.
If you try to do well, your mouth will close, and if you try to do it roughly, your mouth will open.
In English, it's not the person who is good at it, but the person who keeps at it who wins.

Don't memorize it.
The moment you memorize English, English dies.
Memorization is a test-taking technique, not a way to acquire language.
It's not a short-term memory that is forgotten after the test is over,
Automatic memory is needed, which is imprinted on the subconscious through repetition and rhythm.
You need to practice repeatedly listening quickly with speed listening and speaking at the same time with speed shadowing so that your ears and mouth work together.
At this time, English is learned sensorily in the auditory circuits of the brain, not in the head.
Even if you don't memorize it, if you keep listening and repeating it, at some point it will just come out of your mouth.
This is real English training that moves from 'memorization to acquisition'.

Lastly, keep it short.
Studying for a long time does not mean that you will remember it for a long time.
The human attention span is limited to five minutes.
Eric R. Kendall, Nobel Prize winner in Physiology or Medicine
According to the learning mechanism revealed by Kandel, the brain maximizes learning efficiency through short, repetitive stimuli.
10 minutes a day, three times.
The habit of listening and speaking briefly changes your day, and if you do it consistently, it changes your life.
In just 10 minutes, your ears open, your mouth responds, and your memory becomes automatic.
It doesn't have to be long.
You just have to do it often.
Language is not learned by those who sit still for long periods of time, but by those who move frequently.

The miraculous experience of opening your ears to English is no exception for you.

'Will it really work?'
The doubts and perspectives still remain.
That's understandable, because we've been accustomed to grammar- and test-focused English for so long.
I don't believe in all these learning methods.
However, during this time, learners of various ages and backgrounds have shared in this miraculous experience, and the students who are still training in their respective positions today are proving that this is not just a simple learning method, but a life-changing experience.

An elementary school student who used to burst into tears under the pressure of having to memorize 100 words a day at an English academy said, "The world is pink," just 30 days after starting to learn English.
He said, 'I'm happy.'
This was an example of how powerful it is to break away from the oppressive, rote learning of language and experience the joy of learning it.
After a fifth-grade elementary school student in Daechi-dong mastered the 6x speed shadowing exercise, he asked, "Teacher, is there no 7x speed?"
I felt the joy of learning through young children as I watched them set higher goals and take on challenges on their own, even though no one had asked them to.

The thrill of starting to hear sounds you couldn't hear before as you conquer a quest in a game and progressing through the levels at 2x, 4x, and 6x speeds is something that only those who have experienced it can understand.

A student in his 50s shed tears when he heard a classical music melody he had never heard before after his hearing became sharper through deep listening training, a 20-something aspiring pilot who felt limited while studying English in the United States, and an international student who was struggling with English presentations during his doctoral studies. Helping these individuals, each of whom felt a desperate need in their respective fields, is a very valuable mission for me.
It is the driving force behind my 20 years of research in language education.
If English, which has been a lifelong homework, could become a fun tool for communication, wouldn't it be a 'life-changing English experience'?
