Santa Barbara Corpus of Spoken American English Part III was produced by Linguistic Data
Consortium (LDC) catalog number LDC2004S10 and ISBN 1-58563-308-9.
Santa Barbara Corpus of Spoken American English Part III is based on hundreds of
recordings of natural speech from all over the United States, representing a
wide variety of people of different regional origins, ages, occupations, and
ethnic and social backgrounds. It reflects many ways that people use language in
their lives: conversation, gossip, arguments, on-the-job talk, card games, city
council meetings, sales pitches, classroom lectures, political speeches, bedtime
stories, sermons, weddings, and more.
The corpus was collected by: University of California, Santa Barbara Center for
the Study of Discourse (Director: John W. Du Bois (UCSB), Authors: John W. Du Bois and Robert Englebretson. Associate Editors:
Wallace L. Chafe (UCSB), Charles Meyer (UMass, Boston), and Sandra
A. Thompson (UCSB)).
Santa Barbara Corpus of Spoken American English Part III is also part of the
International Corpus of English (ICE) (Charles W. Meyer, Director), representing
the American Component.

The audio data consists of 16 wave format speech files, recorded in two-channel pcm, at 22050Hz.
The speech files total ~6 hours of audio (1.8GB), representing over 116K-words and over 9K unique words in transcription.
The the transcripts are in the following format:

A sample transcript file may be found here.
Personal names, place names, phone numbers, etc., in the transcripts
have been altered to preserve the anonymity of the speakers and their
acquaintances and the audio files have been filtered to make these portions
of the recordings unrecognizable. Pitch information is still recoverable
from these filtered portions of the recordings, but the amplitude levels in
these regions have been reduced relative to the original signal. A
separate filter list file (*.flt) associated with each transcript/waveform
file pair is provided to list the beginning and ending times of the
filtered regions. The file sbc040.flt is empty indicating there was
no personal information to filter out.
The filtering was done using a digital FIR low-pass filter, with the
cut-off frequency set at 400 Hz. The effect of the filter was gradually
faded in and out at the beginning and end of the regions over a 1,000 sample
region, roughly 45 milliseconds, to avoid abrupt transitions in the
