---------------

Each utterance is stored as a sequence of  2  byte  short  integers,  each
short  integer  holding  a  signed 12bit speech sample.  Note: these files
have no CAMSED headers.

3. Structure

The database consists of directories for each of the speakers.  Each of
these  directories holds the spoken utterances for that speaker.  The name
of each speech file represents the word spoken and  the  repetition  index
for  the speaker and word (see the above table for translation between the
stored name and the actual spoken word).
