I am not a professional speaker, however I was reared by a mother who thought correct pronounciation was important. My English (language arts) teacher was a real stickler for correct spelling, grammar, and pronunciation. As a result, I am very conscious of how a name or word is pronounced and spelled. It doesn't take much to learn the correct pronounciation of a name, especially if one's profession involves speaking to audiences or the public in general.
My life's work included working in a university's medical school. I was not trained in medicine. I made a point of learning the correct pronounciation of medical terms. Last month my husband received a phone call from his primary care physician's office. The woman on the phone stumbled repeatedly on the word podiatry. Do you think she was a good reflection on her employer? She was not.
