1) Please listen on a computer in Murphy and Tyl to hear these sounds. Click on each of the four types of sound.  On each page will be an example.  Please click on it to see if you can hear it.  Of the 4 sounds I think "qualcomm" will should work and will be the best.

2)  Then click on the two example pages below to see if they work.  They were created using "qualcomm".  You have to use your back button to return to this page.

alphabet days of the week    

If you can hear the example pages I will start converting the files so that you can use them.  If you can tell me on Monday, I might have them done in a couple of days.
