Voice of America provides a pronunciation guide for names of foreign leaders and dignitaries. Type in a name or choose from an alphabetical list.
Example of Sergio Viera de Mello from the VOA site. In addition to the written phonetic spelling, the site also provides an audio file of name being spoken in translation.
