This .ogg reader will allow one to hear sounds on this:
http://en.wikipedia.org/wiki/International_Phonetic_Alphabet

You need to unpack it, and then on clicking on wiki, click 'open', and then browse and associate the file with Zinf (go to C: program files, zinf folder, zinf player and click it). Next tell window (click it) to 'always associate with this program' box.

Zinf will ask to 'always accoiate with music' etc. Clcik cancel, as you only want it for wikipedia, not for playing mp3s or CDs
