ai_speechfilter is a point entity available in all Source games except Left 4 Dead series.

The entity allows to adjust how much an NPC will idle chatter to other NPC’s and the player. This is quite useful, especially if you have a script setup where idle chatter will seem out of place, or get in the way of a Face Poser scene. Speech patterns for NPCs are defined in Response System.
