Itunes/Ipod help

I have a chinese midterm speech tomorrow and my gf recorded my speech and some of the words that I have a hard time saying, in chinese. The files are a .wav and I added them to itunes and to my ipod, however, the ipod doesn't play them. It shows them in the library but it just skips to the next track (in the playlist) when I select them.

Do I need to change their file status or anything?

Thanks!

*edit* Delete me! I didn't notice this was answered on another post by the same author.

Convert to an *.mp3 file and you should be good to go. Here are a bunch of encoders from download.com if you don't have any:
