In the demo Astarion (who Sven plays as) seems to be doing his own narration...
This may interest you:
It is interesting stuff. With it I might make lean toward a belief that "Full Voice acting" meant different narrators for each origin, and tadpole lady for custom. However, I skimmed through the videos and they all seem to be using past tense, which indicated to me it's all pre-EA-release stuff. Perhaps originally EA was to launch with playable origins, and it was scrapped when they decided to change writing style based on feedback. It would explain why in their first showace they played as an origin - it is something that they have never done again. It might still be plan, and perhaps they are waiting closer to release to record Origins, as it is cheaper to re-record one VO, then all of them as changes are made.
