Gotcha. So there are two characters that I'm currently looking for voices. Jesse (protagonist), and Jack (side character). 

Here's a conversation between the two characters, written in my garbled version of a script:

Jack (casual) "Hey, Jess! How ya doing?" 

Jesse (Distracted) "Yeah...uh, good.... Do you know what happened to Mark?"

Jack (Humorous) "Jesse, unlike you I am not bound to any one section of the company, but, I know three Marks that work here and as far as I know, nothing has happened."

Jesse (Confused) "Well, then you don't know the one I'm talking about: Mark Halfor."

Jack (Laughing) "Yeah, I know him. I saw him just earlier. What's the matter with him?"

Jesse (Angrily Confused) "He's been replaced! How could you not see that? There's some sort of automaton in his place."

Jack (Concerned yet Humorous) "Well, okay. Well I'm busy right now-" (whispers) "Got a meeting in 10 minutes-" (normal volume)  "But I'll take a look at him and tell you what I see later okay?"

Record as much or as little as you want. I just want a sample of each character to see which you can play better.
