Abstract: A mail sorter (22) includes an imaging device (60) to generate a plurality of images each corresponding to one of the plurality of mail pieces (36). The mail sorter (22) performs a character recognition routine on each of the images to sort a number of the mail pieces (36) and identify one of the mail pieces as being unsortable by the routine. An operator input processing subsystem (24) includes a number of stations (74). These stations (74) each include a display and a voice input device. The subsystem (24) responds to the mail sorter (22) to route the images to the stations (74). One of the stations (74) is operable to display one of the images on its corresponding display device and receive vocal input from an operator with its corresponding voice input device in response to viewing the image. The subsystem (24) executes a voice recognition routine to determine address information from the vocal input and provides this information to the mail sorter (22) to sort a corresponding one of the mail pieces (36).
