Kari: (describing the reality of voice over work) It’s very unglamorous and a lot of times with video games or anime you’re the only person in a very small booth — a small dark booth. In the room next to you sometimes there’s only a director and an engineer. You could spend two, three, four days really not talking to anyone which is kind of ironic. You’re just in a small dark room recording lines with only an engineer and a director behind thick glass to talk to. It’s a very bizarre world. It’s very strange.
