Would you care to elaborate a bit?

What exactly do you mean by exctracting the human dragon shouts?
Well, you would extract the shouts from the Voices.Bsa, and if you want the Human Male shouts, I'm thinking that it would be the
sound\voice\skyrim.esm\maleeventoned\voicepowers_shout01_23746423.fuz (made up the numbers in the file, the files are named like voicepowers_shout01_"numbers".fuz, voicepowers_shout03a_"numbers".fuz)
You'd have to extract those, and rename each one to the same file name that the dunmer use.
(It'd be nice if the shouts were named for the shout and word they were....)
That's the very very very basics of it, being able to play each file and hear each shout so you knew which each file was would require converting the fuz to wma (IIRC),
