If you've watched a good amount of anime, you'll begin to recognize a few familiar voices in past anime you've watched. Especially if the anime they're working on is a hit, they're bound to star in other shows. Here are some of the easily recognizable voices in anime.
Known for his roles as Emiya Shirou (Fate), Uchiha Sasuke (Naruto), and Uryū Ishida (Bleach). His voice stands out because of how it changes depending on the character he plays and the emotions needed. When he played Emiya Shirou, he had a rather high-pitched voice, but as Uchiha Sasuke, he talked in a much meaner and deeper voice.
