I pay attention to this. I try to avoid extreme highs and lows for both male and female Sims, because the really high ones annoy me and the really low ones I feel are pretty rare irl. I actually had to go edit a sim yesterday because I completely forgot to check her voice! As soon as she started talking in game I realized her voice was as high as it could go, so I had to go in to change it. She sounded like a mouse especially when I used fast forward ?
