Hi, i am 21 years old and i am facing underbite problem. i've thicker voice. i can't speak clearly. sometimes i feel like i am mumbling. while i am speaking it feels like my nose is blocked and i can't pronounce words properly. but in real my nose is not blocked. i want to ask is that after surgery would i be able to speak clearly and would i be able to get rid of this mumbling. i want to have normal voice like other human being.
