Is it that you have a common last name that everyone pronounces it a certain way and you don’t? or you just want to tweak it for no apparent reason? e.g. the store Target. Most pronounce it as it is spelled. Tar-get. Others want it to sound fancy so they say Tar-shay (sort of a french twist).
I know someone with the surname “Frei” and they pronounce it Fry. Others in the family pronounce it Fray.
