Abstract: Techniques for monitoring of communication in a physical environment are disclosed. The techniques include receiving a textual representation based on verbal communication from one or more users relating to a physical environment. The techniques further include generating a communicated state of the physical environment based on the textual representation and determining an actual state of the physical environment based on one or more measured characteristics of the environment. The techniques further include automatically providing an alert to at least one of the one or more users, based on comparing the communicated state of the physical environment with the actual state of the physical environment.
