This document describes the file naming conventions used for this
distribution and gives a brief description of the various file formats
used.

File Naming Convention
----------------------
File naming follows the following convention:

           fcmg0-A1-t.wav

The first field ("fcmg0") is a prefix representing a unique ID number
for the speaker. The second field ("A1") indicates both which letter
was spoken for that particular file, and which of the two productions
the file represents (each speaker made two productions of each letter).

File Formats
------------
The data were recorded from an analog line using a Gradient Technologies 
analog-to-digital conversion box. The .wav file format used is the RIFF standard 
file format. This file format is 16-bit linearly encoded.
