As I have told you in my previous question, I have heard the CBS news about the Bulgarian president visiting the US here. I don't know why, but the way the reporter has pronounced his name makes me smile. I know that that isn't an issue since we speak different languages, but I was wondering why she pronounced it that way. His name is Rosen Plevneliev. In Bulgarian there are duplicate consonants like s in sauce and z in zebra. In Bulgarian we pronounce it with clear s sound while this reporter has used the z sound.
My question is: What is the rule in English that makes her pronounces it that way.
