There is an established trope of female voice-over for narration like this, maybe linked to the idea of computers having female voices going all the way back to Star Trek? It's probably just cultural programming, but we tend to trust the female voice more than a male one. Maybe some genetic Mother imprinting?
Anyway, I don't care and the voice acting I've heard for the narrator is very good so far, nicely nuanced. I don't think Larian needs to spend more money on this part of the game.
