What does it mean to be eloquent? I believe that being eloquent is like possessing a powerful weapon, or an all-purpose free pass, that allows you to navigate life's challenges more smoothly than others.
Whether it's an important interview, a need to showcase your accomplishments at work, sharing ideas with team members to drive progress, or introducing yourself to someone you've just met, those who are good at speaking will be able to move forward more quickly and easily than others.
This book was written to help those who feel lost at such a threshold.
Those of you who pick up this book probably aren't the speaking masters you see on TV or YouTube.
I think these are people who are about to have an interview or presentation or who have been thinking, ‘I wish I could speak better…’
For those people, this book is a minimal speaking strategy that can be applied and implemented immediately.

No matter how good the content you are trying to convey is, if your pronunciation and enunciation are not good, it will be difficult to achieve the purpose of your speech.
On the other hand, if your pronunciation and enunciation are good, even if you say the same thing, it will be much more trustworthy.
A stable tone and accurate pronunciation make the message you want to convey clearer, and it also has the side effect of making you seem smarter.
It's about becoming a more attractive person.
Among celebrities, some with particularly attractive voices include actors Seo Hyun-jin and Oh Na-ra.
Both of you have very good pronunciation and enunciation.
Of course, there are people who are born with good vocal cords.
You can have a good voice without any special practice.
On the other hand, there are people who have developed an attractive voice that suits them through vocalization and pronunciation practice.
In my opinion, Seo Hyun-jin and Oh Na-ra are closer to the latter.
The good news is that with consistent practice, your pronunciation and voice will improve dramatically.
The more you practice, the faster you will improve, and once you have realized it and internalized it, it is not easily forgotten.
In fact, there are many announcers around me who have developed attractive voices not because they were born with good vocal cords, but through training.
The closest example is me.

The reason why you should use abdominal breathing when vocalizing is not only to produce a pleasant sound, but also to prevent damage to your throat due to incorrect vocalization.
If your vocal cords are damaged due to incorrect pronunciation, your voice will become increasingly unpleasant to hear.
A vicious cycle repeats itself where bad pronunciation leads to a bad voice.
Of course, this process requires patience.
At first, you won't be able to tell if I'm making noise with my stomach or not.
Since you don't feel the change right away, you might be wondering if you should keep doing this.
But once you get used to the correct pronunciation, it will be difficult to make sounds the wrong way from then on.
It is what is called 'embodied'.
If you consistently practice and develop proper pronunciation and thus a pleasing voice, you will gain more than you think.
In my experience, people with better voices than others are not judged harshly even if their work is a little unskilled.
You will have more opportunities to stand out in front of others and your chances of being recognized by others will increase.
It would be natural for confidence to rise.

Accurate pronunciation is a basic quality that broadcasters must have.
But I don't think that quality is only needed for broadcasters.
Among my students, there is one who succeeded in getting a job after struggling for over a year thanks to diligently practicing pronunciation.
There are people who diligently practiced their pronunciation as if they were eating a meal, and before they knew it, they had become presentation experts at their company and even been promoted.
Most of us believe that the reasons we struggle to speak or present well are because we lack confidence, lack logic, or are nervous.
But surprisingly, the cause lies elsewhere, and many people are unaware of this.
Especially the pronunciation.
Because I don't have a chance to check how I usually pronounce things and whether I'm pronouncing certain things wrong.
From now on, try to train your vowels consistently.
I encourage you to speak while being conscious of how you pronounce things.
After a month or two, you will be able to transform into someone who can convey what you want to say more accurately.

Now, I'm going to teach you some practice methods to avoid trailing off.
Try taking a picture of yourself with your smartphone.
"From this moment on, I will speak every sentence accurately." Say the sentence above out loud.
Try to speak as if you are talking to someone, rather than reading a sentence.
I hope you will speak with the feeling of shouting, of declaring.
At this time, try pronouncing the '-da' in 'I will say' correctly.
When I have students practice this, they either emphasize the final '-da' sound and raise the pitch, or lengthen the ending of the word like 'da-a-'.
It is better to say '-da', which ends a sentence, by slightly lowering the pitch compared to the sound before it.
Of course, there are exceptions.
When you first start talking, say hello, or introduce yourself, you can create a lively atmosphere by slightly raising the '-da' sound.
However, in general, the pitch of '-da' should be slightly lowered and the duration of the sound should also be slightly shorter.
But you have to pronounce it clearly so that it can be heard clearly.

“What should I do with someone who makes absurd claims?”
I want to tell that person, “You are wrong.”
But saying this is like losing my side.
To put it bluntly, it's a very aggressive way of pushing people away.
Actually, I was that kind of person.
I used to just point out mistakes and suggest solutions, thinking that I needed to fix the problem.
If you think about it carefully, it's not a big problem if the other person's logic is wrong.
There are many times when there are no problems.
But if you say, “You’re wrong!”, I’ll say, “That’s right.
I was wrong.
Few people will say, “Thank you for letting me know.”
This is because we perceive negative words like “no” and “wrong” as negations of ourselves.
You end up closing your heart before accepting the other person's advice.
But what if you need to point out the other person's mistake? Simply ask questions about the part of their story that's inaccurate.
For example, “What does this part of what you just said mean?” or “I’m curious as to why you think that?”
If you ask about the mistake two or three times, the other person will naturally realize it.
That there is a flaw in your logic, and yet the other person has hinted at it without directly criticizing you.
