I thought about it for a while. There are three things you can do-
(1) Look up the where the person is from on wikipedia, then put his or her name in google translate, set the language accordingly and then hit listen. It works out quite often.
(2) Frovo claims to be largest pronunciation guide in the world. The pronunciation for Saharon Shelah is not availaible on google translate but it's on this site.
(3) Look up sites similar to Frovo. Also, if you can't find the pronunciation of a particular name, you can break it down, and then look it up. A famous person might share the same surname or the first name.
