Help from any ASL-fluent DUers

[realisticphish]

I'm currently in my 4th level ASL class in college, and I'm having trouble finding resources that accurately describe mouth shape/oralized NMS's. I.e., "oo" "mm" "fsh" etc. My teacher has explained the different applications for the different NMS's several times, but I just can't seem to get it, so I've been trying to track down an independant source that explains it. Any help would be greatly appreciated.

And if nothing I wrote made ANY sense whatsoever, I'll be glad to rephrase it ;)

1. Try lipreading resources
