Digital Talking Book Machine
The digital-talking book player is used to play audiobooks stored on USB
flash-drive cartridges. These players are supplied to eligible patrons
through a network of co-operating libraries under the program administered
by the National Library Service for the Blind and Physically Handicapped,
Library of Congress in executing United States Public Law 89-522.
The player is able to play digital-talking books (DTBs) structured in ANSI/NISO Z39.86-2002,
DAISY 2.02, or CEA-2003 formats. The player can play audio files stored as AMR-WB+, MPEG I/Layer 3
(MP3) and RIFF WAV format, either as part of a talking book or as stand-alone audio files.
The user operates the player using a number of buttons located on the top surface. In addition
several player functions occur automatically in response to patron actions or inactions. The
player automatically powers on and gives an audible greeting when the patron plugs the power cord
into a live AC power outlet. When powered on, the player will start or resume the playing of a DTB
automatically when the cartridge is inserted into the player. When operating on battery power and
not playing a book, the player will turn off after 30 minutes of inactivity.
There are two models of the digital-talking book player, the Standard Model (DSl)
and the Advanced Model (DAl).
