Increase your life efficiency by 38%.
By announcer Yoojin Koo,
Voice - Coordinating -
First impressions
Are determined by
55% visual, 7% verbal.
38% = Voice.
Nasal, high-pitched, childlike voice, muffled pronunciation.
Because of habits you didn't even know you had,
You've been losing 38% of your life.
You've been missing out.
Even if you can't change your natural appearance,
If only your voice changes 'properly',
Life efficiency UP by 38%!
When your first impression improves,
Success naturally follows,
Successful meetings / client consultations / relationships.
There are even research results,

"CEOs with good voices
Have higher salaries."
-Duke University research results

"With the other person's voice
We determine trustworthiness, competence, and likability."
-Harvard University research results
Teachers, instructors
Executives at large corporations, lawyers,
Creators with 1 million views
And even ordinary office workers.
Already with me,
They are living life more easily.

"Speak more accurately so that listeners can understand
I am very excited because I think I will be able to have a great voice. Haha.
With consistent training, my voice is gradually changing into the one I want. :)
My voice, which used to sound like an ant, has turned into a deep cave.
*This is a review from a previous version.
"Because you are an announcer,
Wasn't your voice always good?"
No!
Books, lectures, vocal music, even singing techniques,
The amount of money I spent on my voice alone,
Over 15 million won,
Only then,
Did my voice finally change.
Now,
I am sharing that method,
For the first time.

Maker introduction
Actually, I didn't have a good voice from the beginning either.
When I was in elementary school, my homeroom teacher even called my mother and said, "I think Yujin's voice sounds a bit strange." Even when I knocked on the door of an academy saying I dreamed of becoming an announcer, the teacher's reaction was not what I expected.
Still, I didn't give up and practiced hard as I was taught, but what I got in return was vocal nodules.
Whenever I asked my teacher, the answer was always the same: "If you keep practicing, you'll get there." No one clearly explained why it wasn't working or how to fix it.
So I set out to find the answers myself—books, lectures, classical singing, even vocal techniques for singing. Only after spending 15 million won did my voice finally start to change, and now everyone tells me I have an 'announcer's voice.'
I didn't want the materials I made back then to go to waste, so I started sharing them with people around me. That turned into one-on-one coaching, and I saw firsthand how the voices of over 200 people changed.
Your voice can definitely change. I am proof of that.

FAQ
Q1. My voice is not particularly bad. Do I still need a diagnosis?
Many people think that only problematic voices need correction.
However, in reality, every voice has its own unique characteristics and patterns.
Personal Voice is not just a service for those who need correction,
-It helps you understand the strengths and type of your voice,
-And provides a diagnosis to help you use it more persuasively and effectively.
-What kind of impression your voice gives,
-And in what situations it becomes weaker,
Just knowing how to use it better can greatly change your image and influence.
Q2. How is this different from voice lessons or speech training?
Traditional training is usually conducted like this.
"Try lowering your tone."
"Speak clearly and distinctly."
However, each person has
different vocal structure, resonance, pronunciation habits, speaking speed, and tension patterns.
Personal Voice first conducts a diagnosis to
-Analyze individual voice/vocalization/delivery patterns,
-And suggest training directions tailored to them.
In other words, Personal Voice is
the 'voice diagnosis stage' needed before training.
To use an exercise analogy,
it is like a body type analysis before personal training.
Q3. Is it possible to get an accurate diagnosis with only online voice submission?
Yes, it is possible. The Personal Voice diagnosis is not just a simple recording file,
but is based on speech tasks designed to identify characteristics of your voice, pronunciation, and delivery.
-Reading speech
-Natural speech
-Tasks to check vocalization patterns
We comprehensively analyze vocalization, resonance, pronunciation, delivery, and speech habits.
Q4. Can my voice actually improve after receiving a diagnosis?
Personal Voice provides not just a simple evaluation report, but a voice report that includes improvement directions and training methods.
The reason many people do not improve their voice, pronunciation, or delivery is
because they do not know what needs to be corrected.
In the Personal Voice report,
-Current voice type
-Strengths and weaknesses
-Improvement priorities
-Customized speech training are presented.
In other words, instead of vague corrections, you can clearly understand the direction of change you need.
Q5. How is the voice diagnosis conducted?
The Personal Voice diagnosis is conducted based on completing a diagnostic form and submitting a voice file.
Following the instructions, participants
-Fill out the voice diagnostic form
-Submit a recorded speech task,
A professional with announcer experience, trained internally, directly analyzes your voice, pronunciation, delivery, and vocalization characteristics.
After that,
-Personal voice characteristic diagnosis
-Analysis of the causes of problems
-Improvement Direction
-Customized Training Solution
A diagnostic report including this will be provided.
Since an expert conducts a 1:1 analysis and prepares the report, it may take about 5 to 10 days after submitting the diagnostic form. (Usually, you will receive it within a week.)
