Santa Barbara Corpus of Spoken American English Part II was produced by Linguistic Data
Consortium (LDC) catalog number LDC2003S06 and ISBN 1-58563-272-4.
Santa Barbara Corpus of Spoken American English Part II 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), Associate Editors:
Wallace L. Chafe (UCSB), Charles Meyer (UMass, Boston), and Sandra
A. Thompson (UCSB)).
Santa Barbara Corpus of Spoken American English Part II 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 22,050Hz.
The speech files total ~six hours of audio (1.8GB), representing over 47K-words and over 5K unique words in transcription.
Each speech file is accompanied by two transcripts in which
intonation units are time stamped with respect to the audio recording.
The two types of transcripts are defined by the file extension: .trn and .ca. The
text and coding content of specific transcripts are identical. However, the transcripts with
the ".ca" extension are transcripts in the CHAT format for conversational analysis, formatted for use with the CLAN software, available from TalkBank.
The transcripts with ".trn" extension are structured according to the LDC Callhome format, for
use with a variety of annotation tools. (Please also note that transcript coding is not presented as in the ICE standard).
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. There are 4 .flt files which are empty because there was no information that needed
to be filtered out from the audio files.
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

The completion and release of this corpus was facilitated by funding extended by the TalkBank
project. TalkBank is an interdisciplinary research project funded by a
five-year grant (BCS-998009, KDI, SBE) from the National Science Foundation to
Carnegie Mellon University and the University of Pennsylvania.
There are no updates available at this time.
The cost of the first 100 copies of this publication (not counting the copies distributed to
LDC members) is covered by NSF Grant Number BCS-998009, and therefore free of charge;
a $30 shipping and handling fee applies. After these first 100
copies are distributed, additional copies will be available for the production cost of $100 per disc.
