hahaha I actually cringe too hearing my voice but I used to be an MC and works as radio jockey when I was 15. I am just trying to get back into these thing again hehe. There's a channel where I learn how to improve my vocal and it's part of my daily routine now and trying to make it a goal to improve my voice.
There are a lot of japanese concept that I think very helpful and I think it should be explored a lot more.
That's fantastic! I was wondering why you sounded so calm and natural.
