If you are not confident in your English pronunciation
Start with vocal training.

Many people study English with the dream of speaking it well, with the ultimate goal of improving their quality of life by communicating fluently in English.
While consistent effort is important to achieve your goals, the first step is to find your English voice.
Speaking in every language in the world begins with vocalization, that is, the voice, not pronunciation.
Just as there are familiar pronunciations that come to mind when you think of 'German' and familiar pronunciations that come to mind when you think of 'Japanese', the same goes for Korean and English.


The idea is that you can find an English voice that suits you by using the speaking muscles you already have.
To do this, you need to train your muscles using the 12 basic vowel sounds of English.
This will allow you to expand your English pronunciation range and improve your pronunciation of English vowels.
I hope that everyone who is struggling with speaking English will gain confidence in speaking English through this book, with its message of hope and positivity.
