1. A computer implemented method for updating a face glossary repository with face glossary data, the computer implemented method comprising: detecting an acquisition condition, wherein detecting the acquisition condition comprises detecting a presence of a set of face images in a raw data queue, wherein the set of face images are images recorded by a camera; responsive to detecting the acquisition condition, identifying a source of the face glossary data; retrieving the face glossary data from the source, wherein retrieving the face glossary data from the source comprises retrieving a voice command that refers to at least one face image in the set of face images from the source, wherein the voice command includes a timestamp that identifies a time the voice command was given; identifying, by a processing unit, the at least one face image in the set of face images referred to by the voice command by matching the timestamp for the voice command with a timestamp that identifies a time the at least one face image was recorded by the camera to form identification information; and storing, in the face glossary repository, the face glossary data in association with the identification information.
