In Left 4 Dead 2 you can make your character speak by clicking in the thumbstick on controller, or pressing Z or X when using a keyboard.

When looking at an item the quick voice line changes from generic "look" to a more specific "ammo here", "weapons here" or similar. This can be useful on multiplayer campaigns where it can be used to communicate with other players if a microphone isn't available.

But on single player campaigns it doesn't seem to serve a purpose. Identifying an object doesn't immediately give a voice response and there isn't much else in the way of feedback.

Is there any benefit to using quick chat in single player?

It has no effect on their behavior, other than sometimes they respond to you with vocalizations. However, with Left 4 Bots, you can give them vocal commands.

  • Let's go. Hurry. Ready. - those are the commands that make them talk to each other. Making Cortana complain about stuff is half the fun.

  • Interesting. I didn't know that modding (Left 4 Bots mod) could allow bots to be commanded until I've read this answer. May 23 at 1:09
