How would you improve Teens?

I would like to have unique voice actors for teens ... I think teens, children, and elders all deserve unique voice acting and those exaggerated styles. Like for children, their voice is fine. For teens, they should whine more, and have a more immature sort of tone. Something that just separates them not only visually but also audibly. And elders of course should sound very "old" with those raspy voices. Like the typical old guy with a cane trope. It should embody those things in my opinion.
