1. A method of enforcing compliance, comprising: receiving, by a computer system, a VoIP communication; comparing, by a computer system, at least a first portion of the communication to a lexicon stored in a storage device comprising a plurality of auditory representations to determine if a first auditory representation is absent from the first portion of the communication, wherein the comparison of the first portion of the communication to the lexicon occurs at the time the auditory VoIP communication is being received; storing, by a computer system, the determination in a storage device if the first auditory representation is absent from the first portion of the communication; generating, by a computer system, metadata based on the VoIP communication, wherein the metadata is stored in the storage device; and quarantining, by a computer system, the communication if the first auditory representation is absent from the first portion of the communication, wherein the absence indicates that the communication is not compliant.
