How to make your voice sound the same as when you speak?

I feel the same way. Listening to myself is relatively stable and heavy, so I only like to sing by myself. I was trapped when I got to ktv. . . The voice is not bad, but it's weird, and because I sing a lot, I always like lower songs, but I know it's only suitable for myself to sing to myself. . 、

At present, my method is to open my mouth as wide as possible and let the sound come out, so that the sound is closer to the sound that bone conduction hears itself. It's hard to estimate the exact same, but at least it's nice to sing it to yourself.
