If you are really a very active Jew then you would know that the Name itself is never pronounced aloud and that the Hebrew letters that comprise it could possibly be the literal spelling of neither Adonai nor haShem It is the ineffability of the Name that leads pious Jews to avoid fully spelling out God which in English also functions as a name for Him of sorts  Since the four letters of the Name are never pointed its pronunciation cannot be determined from texts and if there exists a Rabbinic tradition as to its pronunciation those who know of it have not chosen to reveal it As Tetragrammaton explains Yahweh is the standard scholarly pronuncuation which may or may not be actually correct Jehovah is certainly wrong whether the J is spoken as originally intended or not
