Directory Structure
-------------------
This document describes the directory structure of this
release. 

Following is a written description of the directory
structure in this release:

  readme.txt	General information regarding the corpus.

  docs/		The documentation directory. This
		directory contains further documentation for
		the Speaker Recognition corpus.

  labels/	Phonetic labeling directory. This directory
		would contain phonetic labeling information
		if it existed. For this corpus, it is empty.

  misc/		Miscellaneous directory, possibly
		containing software tools and scripts.

  speech/	The speech directory contains the actual 
		.wav files. There are many numbered
		subdirectories within the speech directory.

  trans/	The transcriptions directory. This directory
		contains non-time-aligned word-level
		transcription of each of the speech files.

This corpus requires approximately 4.8GB of disk space.

Visually, the directory structure looks something like this:

readme.txt   /docs   /labels   /misc   /speech   /trans

This release contains a /speech directory that contains all
of the recorded utterances.  In the /speech directory are
subdirectories for each speaker.  Within those
subdirectories are *another* layer of subdirectories for
each recording session.  The files themselves are 
encoded with the id and session number as well. See the
formats.txt file in the /docs directory for more information.

Along with the speech files, Release 1.1 contains
transcriptions of nearly all of the utterances and gender
and age information for each speaker.  All of this
information is found in the trans.txt file in the docs
folder. In addition, the individual transcriptions have
been placed in the /trans directory, which uses a structure
that exactly parallels the structure of the /speech
directory.
