I don't always pay attention very well when an NPC is talking (In fact, there's one talking to me in the background while I'm typing this question). Usually, it's because I'm thinking about the words the character is saying rather than looking at the screen. This means that I often miss the personality indicators lighting up to tell me whether a person is an alpha, beta, or omega personality type, and when I get to a speech challenge, I often need to guess to figure out which personality the person has.
It would be nice if there was a way to identify what sort of person I'm talking to based on their words and voice rather than looking at an indicator. I presume Human Revolution is the kind of game where the designers took something like that into account and made the various personalities fit. With that in mind...
How can you tell just by listening to a person's dialogue if they are an Alpha, Beta, or Omega?
