Correct. We considering such but it quickly became a moot point, one of many, many ideas simply dropped for lack of time and resources.
In the end, PC VO was done so late in the process that we had to go with what we got, which a number of us weren't happy with (Ysuran in particular). Things were too hectic for me to make that recording session, though I'm not sure my presence would have helped any.
All things considered, though, I'm quite pleased with how BGDA2's VO turned out.

The possibilities of the whole "dialog as a cut scene" where the entire sequence--PC responses included--is scripted have often intrigued me, but whether that's "appropriate" (whatever that means) for PC RPG's or not... that's a matter for debate.
There's also the idea of third-person PC responses, less "'Move it or eat my fist!'" and more "Threaten the guard," allowing the player to imagine exactly what he or she is saying or doing while getting the intended action across to the game... but that brings a whole new set of problems to the table. It's likely that there's a NWN module or something like that out there now... if not, I suppose one could be made as a sort of testbed for that mechanic.
