Ask how to pronounce advisor's last name? I am an undergraduate working with an advisor, but I do not know how to pronounce his/her last name. I have talked with several different people who work in the department, and have heard the name pronounced several different ways.

Is there a polite way of asking an advisor how to pronounce his/her last name?
By the way, I have heard your last name pronounced a few different ways and I want to make sure I get it right. Can you teach me the correct way to pronounce it?
