So I'm a teen and whenever I look through videos or my friends make me repeat what I say I get really pissed off because every time when I talk I mumble and It doesn't seem as I am it's quite annoying as everyone looks at me like WTF is he saying? So has anyone had this problem before? I have a really deep voice always stand up straight good eye contact enough air I don't talk to fast but sometimes I do. I'm sometimes the quiet person. So Has anyone been through this were you've been mumbling it's just getting so bad now I'm angry at myself? Anyway to fix this?
