If a student does not feel welcome in a class, as an instructor, you are swimming against the tide, and not addressing them as they prefer, is swimming against the tide.
I always confirm, not only the pronunciation of a student's name, but a preference for how they would like to be addressed. I have seen some unusual name swaps. No matter what the roster states as the name, go with what the student states. Building a rapport with a student begins with using their name, what they respond to, whether the data on the course roster or not.
