9. A non-transitory, computer-readable medium comprising computer-executable instructions that when executed cause at least one computer processor to: receive a call-related event notification message indicating an existence of a call, the call-related event notification message comprising a call reference associated with the call; generate a call instance data structure associated with the call reference in response to receiving the call-related event notification message; receive at least one speech-related event notification message originating from a speech analytics module, the at least one speech-related event notification message comprising a first indicator of a semantic speech characteristic detected in speech audio of the call indicating a meaning of speech or uttered word made by at least one party on the call, a second indicator of a non-semantic speech characteristic detected in the speech audio of the call being pertinent to at least one party on the call or delivery of the speech by at least one party on the call that does not directly indicate the meaning of the speech or the uttered word made by at least one party on the call, and the call reference; in response to receiving the at least one speech-related event notification message, perform a first particular application; and store data indicating receiving of the at least one speech-related event notification message in the call instance data structure.
