1.Install WoW again (old disk, no BC) *NOTE: you wont have to keep it on ur comp, just belive me*
2. There are 2 ways to do this:
1.Copy all the .mpqs to another folder such as 'OldWoWMPQs'
2.go to an uploading site and Upload all the MPQs in packages
(this helps if u want to share the MPQs with MMowned)
3. Open up MyWarcraftStudio (older verion will work)
4. Save the new MPQ archive in a 'model edits' folder*
5. When u want to use you can do 2 things:
1.Make Speech.mpq or speech2.mpq or somethin

**
2.Convert it into an addon thing so u can keep in ur addon's folder***
6. There you go!!!

Now you are done u can delete the nwe WoW, but make sure to keep the MPQs if u put in a new folder.
*make sure u can keep track of what moedl edit it is (for example, name it: 'DbeartoBE' (which stands for Druid Bear to Bloodelf))
**sometimes the speech2.mpq works, and sometimes it doesnt : / dont ask why
*** im not sure how to do this, but i will try to get my friend to tell me
