　　Dear Jimmy，You ask me why our singing and speaking voices are different. It's a very good question relating to the scientific study of sound.

　　When a person speaks, he uses a bunch of different structures inside his body: his lungs, the muscles around his lungs, his larynx (喉头) (voice box), his vocal folds (声带), and the spaces above his vocal folds. When a person sings, whether he is a professional opera singer or your little brother singing “Jingle Bells, Batman Smells”， he uses a bunch of different structures inside his body: his lungs, the muscles around his lungs, his larynx, his vocal folds, and the spaces above his vocal folds.But your singing voice does sound different from your speaking voice. One reason is that you do not use as much huge pressure when you speak as when you sing. Another reason is that you use more of the spaces above your vocal folds when you sing than when you speak. This allows more echoing (回声) and makes your singing sound more resonant (洪亮的)．
