Q. If I made a shevuah and use Hashem’s name A’’D, but I pronounce it as adinoy. i.e. (The daleth was pronounced with a chiriq). I am obligated to keep the shevuah ”“ is this a shevuah according to the Torah?

A. Any oath and promise has to be kept regardless of having been said with Hashem’s name or not.
Rambam (Sefer Hamitzvos 62), Shulchan Aruch (Y. D. 203),warn us sternly not to swear an oath that has no purpose. This mitzvah is derived from the words of the Aseres Hadibros, “You shall not take the Name of Hashem, your G-d, in vain.” Aruch HaShulchan (H.M. 92: 15) mentions that in our days we abstain from making any oath even in Beis Din.
Horav Shlomo Miller’s Shlit’a opinion is that one has to be extremely cautions not to incur in the great transgression of expressing a vain or false oath with Hashem’s name, even when not spelled or pronounced properly. Often different communities and traditions differ in their ways of pronunciation, and it likely is counted as His name in other locations. See question 808 and 809 in regards to answering omein and complying one’s obligations with such names.
