Gotta say, it's pretty nice to have voicelines since it helps make the characters feel more fleshed out. Maybe it's too early for me to think this, but, like a comment I saw somewhere, they sometimes feel like they don't fit the situation or are just simply jarring to hear. I'm fine with the current setup(Few dialogue boxes have voices), but if you don't like it, I think the more generic voicelines will work just as well.
This is mostly a nitpick though, I'm thoroughly enjoying the story. The voices really help make FVN feel more real. Hope you keep up the good work!
