Why would she leave the house? There's the old joke that women belong in the kitchen. In traditional roles which are still not questioned because they work in some cultures, she really wouldn't need to or likely be encouraged to wander the park. Little olds ethnic grandma's food taste so good because she only knows how to take 5 hours to build and treat a full dinner.
As for voices, try this; do an impression of a big important person. You're king, decree it. Feel that vibration in your chest? That's the vibration that travels. Now do an impression of a mouse, it's your head that vibrates now, doesn't it? You might make a shape to cut more like that but your voice burns up before anyone can hear it. Between women and men, women use the head voice more and really does make them hard to hear sometimes. The chest voice makes men too easy to hear clear through walls and all.
