so that scene of yamato trying to imitate sasori's voice was anime-only, huh. Now that I think about it the manga never actually discussed what Sasori's voice sounds like, and there's no implication that his voice changes between Hiruko and his true form. So there's a good chance Hiruko has a funny twink-voice or Sasori has this big-guy-smoker-voice even in his true form.
