As nice as this would be, there are some people that are completely stubborn about how they pronounce things.
For example, one of my rl friends pronounces Xarcabard "ECKS-ka-bard"... when it should be pronounced "ZARK-a-bard"; I've corrected her dozens of times, but she refuses to say it right.
This is the reason why I don't like using skype or ventrillo, mispronounciations irk me.
