I still can't get it to work right. It seems to have affected the length of time that the NPCs lips are moving but not affected the subtitles themselves. Someone on Nexus suggested it might have to do with a bad uninstall/reinstall but thats not the case. This was the first mod on a clean GOTY/Morroblivion install. They also suggested that maybe the installer I used messed things up, but I actually installed it by hand (so to speak) - created the necessary folders and copied all three files according to the very, very brief readmes instructions. I've checked the green box on Wrye Mash to launch the game with OBSE and I've tried skipping bash and just using the OBSE launcher itself. Either way my other OBSE plugins work fine. Its just this one that isn't.
Any suggestions would be most appreciated.

If the lips are moving but it
If the lips are moving but it cuts out fast, I presume you're missing the 8 second silent voice file. Check if you have created the folders with the right name.
