i need to learn to do that
1. get a program called GCFScrape
2. use it to open "Steam\SteamApps\portal english.gcf"
3. In GCFScrape navigate to "Root\portal\sound\npc\"
4. Right click the folder "turret_floor" and left click extract.
5. Exit GCFScrape and go to where you extracted it, all the sounds will be their.
6. the sounds all have nondescript names so it pays to listen to each one and rename it so you know which is which.
7. Next go to the "control Panel" and open "Sounds and Devices" (make sure its in classic view if using vista or win 7) and go to the "Sounds" tab.
8. Select an event to assign a sound to, left click "browse...", open the sound file you want to attach, then click the little arrow to make sure you picked the right one.
9. Repeat the step 8 until you have assigned all the sounds you want. (you don't need to put a sound to every event.
10. Click "Apply"
and your done
