Anyone can have a good voice.
I was convinced as I experienced my voice changing and the voices of my students changing.
We speak and live constantly.
That's why you need to have a good voice.
My voice is my means of expressing myself.
I use my voice to express who I am, what kind of person I am, and what I am thinking.
As a result, a good voice brings positive changes to life.
Especially, work life is a series of reports, meetings, and presentations.
If you report in a small, trembling voice, it sounds uncertain.
The project doesn't seem to be going smoothly and its results seem uncertain.
On the other hand, speaking in a clear and confident voice builds trust.
I feel like I'm doing a good job and my boss notices me.
That impression lingers long after the presentation is over.
Naturally, promotion also becomes faster.
I have had students who took my voice lessons and were promoted to executive positions within a year.

While breathing deeply, say 'Ah~' and then change the shape of your mouth to say 'Hello'.
It's like saying 'Ah, hello' with just one breath.
He even says 'hello' in a low voice without changing his tone.
The stomach slowly goes in as if doing abdominal breathing.
Practice maintaining the volume and tone of the sound until the last letter 'yo', and without the sound getting smaller or the tone getting higher.
One thing to be careful of is not to hold your breath while saying 'Ah~' and then say 'Hello'.
You have to say it in one breath.
'Ah~' is often said in a low tone, but in 'Hello' the tone sometimes rises.
This is where the habit of speaking in a high pitch comes from.
Let's be careful to keep the tone of 'Ah~' intact.
Place your hand on your stomach and check that your stomach is gradually sinking in until you reach the last letter.

One student said that he records every meeting with the company representative without fail.
It is difficult to understand because the representative speaks quickly and has imprecise pronunciation.
He said that after the meeting, he listens to the recording with his team members and understands the instructions.
How inefficient.
If the CEO had a good pronunciation, the employees would have been able to work more during that time and contribute to generating profits.
How does pronunciation affect the delivery of your message? No matter how well-crafted your presentation is, if your pronunciation isn't good, it won't reach your audience.
In other words, delivery comes first, and understanding the content comes next.
Even if you have a high level of intelligence, if your pronunciation is not good, you will not appear to be knowledgeable.
No matter how great your business skills are, if your pronunciation is not good, you will lose your persuasiveness.
Before you can determine your abilities, you will first notice that your pronunciation is not good.
In this way, pronunciation is the primary means of conveying what you want to say.

---From "Step 2, "People look different just by having good pronunciation"

If the first syllable is harsh, lower the tone.
Let's pronounce 'vegetable'.
The tone of [Chae] will be high.
The strong sound is a letter created by adding 'ㅎ' to the ordinary sounds 'ㄱ, ㄷ, ㅂ, ㅈ'.
The sound of wind is created by combining 'ㅎ'.
Therefore, the loud sound has a light sound value, so the tone rises when it comes to the first syllable.
People with high-pitched voices speak louder.
This will raise the tone of the entire sentence, reducing its power of delivery.
When a strong sound appears at the first syllable of a word, deliberately lower the tone and pronounce it.
The tone increases from the next letter after the loud sound.
When lowering the tone of the first syllable, do not reduce the volume of the sound.
The sound of the letters must be consistent to ensure effective communication.
If only the sound of a specific letter is loud, only that letter will stand out and the transmission power will decrease.

A sentence should be read in one breath to convey its message effectively.
But if the sentence is long, you have to take a breath in the middle.
At this time, the breathing area is indicated with a slash (/).
There are three places where slashes can be used:
First, it indicates where sentences are connected by connective endings such as '-de', '-go', '-seo', '-myeo', and '-a'.
Take a breath at the point where two or more sentences are combined.
Next is where the subject is.
Breathing after the subject has the effect of emphasizing the subject.
Finally, breathe after phrases that can be deleted without affecting the meaning, such as adverbs or adjectives.
One or two slashes per sentence is appropriate.
In other words, the less you breathe, the higher the transmission power.
If you take frequent breaths within a sentence, the content becomes abrupt and the delivery is reduced.
Because you need to rest as much as you breathe.
Let's split long sentences into pieces.
---From "Step 3: "Just by changing your tone of speech, your words will start to make sense"

Speak in the same tone you use in everyday conversation.
Don't you use the formal style when meeting people at work?
Don't you use the formal form even when eating or drinking tea with your superiors?
You can just say it in that tone.
It was already difficult to give a presentation, but now that I have to change my tone to Tanaka style, which I don't usually use, it doesn't feel right and I feel uncomfortable, which makes me even more nervous.
A presentation is a conversation.
You have to face the audience one-on-one and talk to them.
If you want them to listen to your story and follow your opinions, present it with the audience in mind.
The audience sees the presenter one-on-one.
So we need to talk.
It is no different from a conversation, except that the presenter stands and talks for a long time.
Talk face to face
---From “Step 4: Anyone Can Make a Persuasive Presentation”

Nonverbal factors are pervasive and have a huge impact on decision-making.
His appearance, image, and atmosphere tell us what kind of person he is.
Habits combined become personality.
Behavior is an indicator of character.
Therefore, you need to think carefully about what posture you will use when speaking, what kind of gaze you will have when looking at the other person, what attitude you will adopt, what facial expression you will make, and what gestures you will use to convey your message.
The audience listens and watches the presenter.
This is why we need to train nonverbal elements.
