# Key Phrase Expert - Deployed
The KeyPhraseExpert is able to respond to specific phrases. For example: “help me”, “restart the simulation”, “quit”. This expert is used to map user utterances matching (or similar to) their corresponding keyphrases to simulation actions. It is common to use this expert in all applications and often works in tandem with the HMGraphExpert to handle unscripted actionable inputs. Any reaction to a phrase can be managed by this expert whether it is feedback to the user directly, a change in an object's state, direction to an npc, etc.
