I sure wish Bethesda, or someone else, had created a bunch of fairly generic dialog fragments that people could use to create simple greeting and so on by simply dragging the short fragment into your dialog scene. The statics and misc items are all drag and drop, why not simple bits of dialog? Having to run around to your acquantances looking for someone with the right voice every time you want your npc to say "hello" is ridiculous. Sure, because they couldn't record a hugh number of speech fragments what you could say and the voices you could use would be limited but it would be better than nothing.
