Santa Barbara Corpus of Spoken American English Part IV was produced by Linguistic Data Consortium (LDC) and contains approximately 5.5 hours of conversational and prepared English speech and associated transcripts. The corpus was collected by the University of California, Santa Barbara (UCSB) 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)).

The corpus 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 gender breakdown for speakers in this corpus was: 33 male, 25 female. In addition, the following metadata is included: age, dialect of english, dialect state, current state, highest level of education, years of education, occupation, ethnicity.

The audio data consists of 14 WAV format speech files, recorded in two-channel PCM, at 22050 Hz, representing over 58,000 words and over 6,000 unique words in the transcribed text. The corpus also includes transcript files in TXT format, as well as files specifying spans in each audio file that have been filtered to remove personal identifying information.


For an example of the data in this corpus, please examine this audio sample (WAV) and its transcript (TXT).


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.
