Jews, How Do You Directly Address God?

I know that many devout Jews refrain from speaking the name of God, and often from even writing it. I have heard of the phrase Ha-Shem (The Name) being used in place of the name of God when speaking of God, but what is used when devout Jews address God? Thanks for your thoughts.
Update: Jew is a nouns, Jewish an adjective, Jewish People a compound noun phrase. My sister who converted to Judaism calls herself a Jew as does her husband who is Jewish by birth. I mean no disrespect. Thanks.
