“There are certain rules to speaking well.

“The best practical book on business communication!”

People who are good at speaking have one thing in common: their stories are logical.
Logical, clear language can persuade others in a pleasant way, help you get what you want, and sometimes even muzzle the mouths of illogical opponents.
So, everyone wants to learn to speak logically, but it is not easy with just short-term training.
The recently published book, "You Can Speak Logically Too," is a book in which the author, who has won 68 prizes in the Toastmasters Japan Contest, a speech competition, and holds the highest record in Japan, including first place and national champion positions, introduces in detail the "PREP technique," a logical speaking formula.


PREP is a speaking technique that is an acronym for Point, Reason, Example, and Summary.
This is a method of first stating the conclusion of the story you want to tell (P), then presenting the reason (R) and example (E) for it, and then summarizing it again at the end (P).
Whether you're selling something to a customer, reporting to your boss, presenting an agenda at a meeting, or conducting an interview, the PREP technique is as easy to use as a formula when you want to logically persuade someone.
This is a must-read, especially for hard workers who want to be recognized for their hard work.
Because it is the most specific and convenient way to logically and without hesitation answer the question, “What is the conclusion?”


“I’ve found a book I can confidently recommend on how to speak logically.” Bok Joo-hwan, CEO of Thought Organization Class, Korea’s leading thought organization consultant, strongly recommends this book and willingly volunteered as a reviewer.
If CEO Bok were to recommend just one method to people who ask him about "logical thinking and speaking skills," he would recommend the PREP technique.
In that respect, this book was recommended as the 'best practical book in the field of business communication' as it clearly organizes the PREP technique and explains the principles in an easy-to-understand manner.

We must learn to speak and think logically so as not to be swayed by the illogical people around us.
During meetings, you may encounter colleagues who insist on their own opinions with illogical arguments, or you may encounter customers who give you unreasonable assignments or make unreasonable demands simply because they are your superiors.
How great would it be if we could silence the other person with logical, clear words, persuade them nicely, and defeat them in one fell swoop?
These are the crucial moments when logic determines the outcome.

The way to convey a story in a way that is easy for the other person to understand is simple.
The first of these is ‘making one sentence shorter.’
In short, it is splitting the sentence.
'Sentence splitting' can be applied to any writing.
For example, what if a book had 100 pages, each with its own chapters? It would be incredibly boring, not to mention disorganized.
It is much better for conveying and understanding the content if you divide the 100-page content into 10 chapters of 10 pages each.
The same goes for speaking.
No matter how interesting a story is, if it goes on endlessly, it is difficult for the listener to understand all of it even if they are focused.
However, if the speaker summarizes the story in short, key points, it becomes easier for the listener to understand and focus more on the content.
In other words, if the speaker feels like the story he or she wants to tell is going to be long, it is better to split the story into parts and then move on to the next story.

No matter how logical it is, if you speak dryly, it will be difficult for the listener to fully accept it.
If you focus only on logic without knowing these facts, you will hear a reaction different from what you expected.
I often hear responses like, "The words are logical, but the content strangely doesn't resonate," or, "I heard it, but I can't quite remember what it was ultimately trying to say."

When you hear the word 'memory', some people may think back to the times when they struggled to memorize things before a school exam.
You may also remember struggling to memorize English words.
You probably memorized it over and over again, writing it out by hand, looking at the flashcards, and highlighting it with a highlighter.
The most important thing to memorize even one short word is ‘repetition’.

If you want to speak logically using the PREP technique, you must choose the most appropriate R (reason) among numerous Rs.
Thinking about it another way, the more Rs you can find, the more room you have to progress the story.
Depending on which R you choose, the way you choose the E (evidence or example) that follows it also changes.
It's like playing a game with multiple cards in hand.
To increase logic, you must eliminate reasons based on personal feelings or beliefs from among numerous choices and choose something that everyone can agree on.

It makes sense to repeat what was said earlier at the end.
Because people remember best what they heard just before.
Usually, memories become blurred over time.
Everyone remembers what was for lunch today, but it's confusing when you go back to what was for lunch yesterday or the day before.
Likewise, what we remember most clearly after a conversation is what we heard just before it ended. The PREP technique involves stating the main point at the beginning, but as the conversation progresses, the main point naturally becomes blurred.
Reiterating a key point at the end of a story increases the likelihood that the other person will remember it after hearing the entire story.

Presentations and speeches may seem similar, but there is a big difference.
When conveying data or manuscript content, a presentation should be more appealing and easier to understand than a speech.
Attendees listen to presentations with the expectation that they will gain a deeper understanding of the content and be able to agree with the arguments made by the speakers than if they had simply read the material.
In particular, I expect that I will be able to make many people understand at once and persuade them by leading them to a conclusion.
Therefore, you need to speak in a way that meets those expectations, and the best way to do so is through the way you structure your presentation.
