I doubt they'd include a voicebox inside of a Pokedex.

I think it might act like Goombella and Goombario (from the Paper Mario series), and that it will tell you a bit about the foes. Not as much as what the "Tattle attack" (not really an attack, it really is just there for you to know a bit about the stats) would tell you about the Paper Mario foes, but some of the information?
