N2wxb Here, hello. I use AT&T voices also, Crystal Is a very good choice. I found that you have to use the setting for Crystal no 2-d lipsync, and you should get lipsync in 3-d to work. I got Crystal, julia, and lauren. They do sound real! Did you install both disks(mike and crystal)I know that its a 2 disk install and I never tried to do the install with just the crystal disk.I just don't use the Male voice. I also am usiing XP-SP2 and have no problems.I set Crystal as my default voice. question, do your other voices work? If so you might want to uninstall, then reinstall the AT&T voices. I hope thats some help.
