The Linguistic Data Consortium (LDC) is pleased to announce the
availability of the Switchboard-2 Phase III Audio.  This twenty CD-ROM
publication contains audio speech data suitable for research,
development, and evaluation of automatic systems in:

speech-to-text conversion
talker identification
language identification
speech signal detection

The Switchboard-2 Phase III collection focused primarily on the American
South. The project's goal was to target native speakers of
English in the American South, balanced by gender, to participate in
(10+) 5-6 minute conversations on a variety of telephone (land line)
handsets. The LDC collected a total of 2,657 calls, or 5,314 sides, from
640 participants (292 Male, 348 Female), under varied environmental
conditions.

The Switchboard-2 Phase III Audio release contains speech data files
only, along with documentation describing speaker information, call
information, and audit information. The data files are not compressed.
