All of the links on the previous page have a number next to them (14.4 & 28.8) or say "ISDN." Click on the 14.4 sound clips if you have a 14.4 modem in your computer. By the same token, click on the 28.8 clips if you have a 28.8 modem. ISDN users should click on either "single channel" or "dual channel" ISDN (depending on their connections--contact your service provider if unsure). If you do not know what type of modem you have inside your computer, experiment by clicking on all the links and decide which sound best.
If you receive a message that says your computer is not fast enough to play the recording, you have either clicked on a recording rate which is too fast for your connection, or you do not have the latest version of the RealAudio Player. Make sure you have Version 3.0 of the RealAudio Player.
