How to make my voice more girly?

My voice is so unfeminine when i listen to recordings it sounds like a straight out boy.please help! are there any foods that help your voice sound more feminine and my voice isn't that good too. i have a tiny lisp and sounds like i have a cold when i speak. my voice is watery too like my mouth is full of saliva. Plus my voice isn't adorable like some girls with more guyish voices. it is slow and annoying. is ther anyway to just get it a little more high pitched sweet and clear because like i said it sounds like i have a runny nose.
