I remember asking a lot of people if Ventus sounded different than Roxas, but a lot of people couldn't tell the difference. I anaylzed comparisons and I KNEW after playing BbS and Days that there had to be a difference. People said they were voiced by the same person (Duh) but it would be odd to have the same voice, right? A little bit of spoilers here Well, in 3D - there are scenes of Roxas and Ventus talking. Roxas has a lower pitch while Ventus has a higher pitch. Something I thought was true since the start. So Yes... THEY SOUND DIFFERENT.
