This is probably a really stupid suggestion but just in case.
Do you and your wife drink alcohol a bit? If so might it be worth having a couple of drinks in a quiet setting with her one evening with microphones running? I'm not suggesting getting wasted! I'm just wondering whether it might help to catch her getting more animated or "natural" in conversation. I was thinking this might help make the resulting synthesized speech capture even more of her personality than reading children's books or subsets of AI corpora etc.
