1. A method for voiceprint based location awareness comprising:

  • receiving a speech from a speaker proximate to at least one of a plurality of microphones within an environment;

    processing the speech to produce an utterance to determine the identity of the speaker, wherein the identity of the speaker is associated with a voiceprint, wherein the identity is associated with a user credentials of a computing system, wherein the user credentials uniquely identifies the user within the computing system;

    analyzing the utterance to establish a zone in which the speaker is present, wherein the zone is a bounded region within the environment, wherein the analyzing comprises of at least one triangulation computation that determines a user location based in part upon acoustic echoes unique to the bounded region resulting from the speech or from ambient noise in the environment; and

    mapping the zone within the environment to determine a location of the speaker.
