"Every first lesson started the same way:
finding out what kind of voice you have."

I have worked with voices for about twenty years and taught music for much of that time. Every lesson began the same way: we found out what kind of voice a student naturally had, then chose songs and practice that fit it. That is the foundation of voice training.

But even professionals find it hard to judge their own voice objectively, and there were few objective measures to help. As AI arrived, I saw that we could finally look at voices in numbers and group them in a meaningful way.

So that anyone can discover their voice easily and enjoyably, and grow. So that students preparing for auditions and working coaches can practice and teach with more precision.

Your voice plays a big part in first impressions and in how you express yourself. It can earn trust like a news anchor's, or put people in a good mood like a comedian's or a host's. When we meet older relatives in Korea, we say "What a strong voice, you must be in good health." I believe that using your voice well and keeping it clear supports a healthy life.

Far more people want to sing well than you might expect. That is why Bureum's first service, VocalDNA, sorts voices into 16 types in a friendly, easy and fun way, so everyone can find a way of enjoying life that suits them.
