As a session chair, how to familiarise oneself with the pronunciation of speakers' names? The organisers of a conference have informed the session chairs what is expected from them.  On the list of duties listed is for chairs to familiarise themselves in advance with the pronunciation of the speakers' names.

In practice, how do I do this?  Speakers come from all the countries in the world.  It's not practical to contact the speakers in advance.  Is there any way to try this systematically?
When I am chairing a session, I always check a few minutes beforehand to ensure that all of the speakers are there.  That's also a good time to check on  pronunciation of names.  Just say something like:


  Can you please say your name for me? I'd like to pronounce it right when I introduce you.


Then it will be fresh in your mind, there'll be a decent chance of getting it right, and the speaker will know that you cared to consult them and try, even if you do end up screwing it up.
