TalkBank Switchboard Corpus, Version 0.1

Speech data and text transcription is Copyright (C) 2000 University of
Pennsylvania.  Other transcriptions and annotations are the copyright of
their individual authors (as identified below).

Permission is granted for use of this material in accordance with the
Open Content License [http://opencontent.org/opl.shtml], a copy of which is
included on this CD-ROM.

This CD-ROM contains speech files, transcripts and annotations for 36
calls from the Switchboard Corpus [www.ldc.upenn.edu/Catalog/LDC93S7.html].

The Switchboard corpus has been enriched with various kinds of annotations
since it was first published.  Full details are found in [1], which is
included on this CD-ROM.

From the original set of 2438 calls, 36 calls were selected which had
complete discourse and treebank annotations and significant phonetic
annotation.

The TalkBank project [www.talkbank.org] seeks to enrich these annotations
with as many new kinds of annotation as possible, and also to complete the
partial phonetic transcription.  A subsequent version of this CD-ROM will
include the annotations that others provide to us.  We earnestly hope that
interested members of the community will contribute annotations,
exemplifying their models on a common set of data, leading to a better
understanding of the models, and of their similarities and differences.

Where maximal overlap with existing phonetic annotation is required, please
begin by annotating calls which have the most ICSI phonetic annotation
(2830, 2887, ...).  For details on annotation coverage, please see
tables/annot-summary.tab.
