I have no idea how to use the GECK, but I was thinking about purchasing the PC version and giving this thing a whirl. Is there a capabiliy to record and place voice tracks within the game for dialogues?

You'll have to use your own software to record tracks, but yes setting sound files for dialog is how it works. In fact, I'm pretty sure that if you DON'T have sound files, you need to hack it with silent ones (Or so it was back in Oblivion?)

Yes of course. You can even use the geck to record your own audio files, but you cannot edit them in any way so another program is recommended for doing so.

FYI, I've done it in the original GECK. Unless they made it easier, maybe they actually have a lipsync Generator, instead of having to import them from the TES:O v1.0?

Other wise it takes hours to do like 10 lines.

Nope, they did not fix lipsynch gen. You must still use the TES CS. D: I really wish they had.
