Message 1: 1997 Mandarin Broadcast News Speech and Transcripts

From: LDC Office <ldcunagi.cis.upenn.edu>
Subject: 1997 Mandarin Broadcast News Speech and Transcripts



Announcing a NEW CORPUS from the LDC


***************************************************
1997 Mandarin Broadcast News Speech and Transcripts
***************************************************

This collection consists of 30 hours of recorded broadcasts
and transcripts that have been drawn from the following
sources: 

 Voice of America (VOA): United States Information Agency Radio
 People's Republic of China Television (CCTV)
 Commercial radio based in Los Angeles, CA. (KAZN-AM)

Of these three sources, the first two comprise the bulk of the
collection, and are represented in roughly equal amounts; only
a relatively small sample of KAZN-AM recordings are included,
owing to the relatively high proportion of unusable material
(commercials, local traffic reports loaded with California
place names, etc).

The transcripts were created by native speakers of Mandarin
working at the LDC; they are in GB-encoded form, with SGML
tagging to identify story boundaries, speaker turn boundaries,
and phrasal pauses; these tags include time stamps to align
the text with the speech data. Word segmentation (white-spacebetween words) is included. A working DTD is provided, and
the markup is consistent with that of the 1997 English and
Spanish Hub-4 collections. 

Because of restrictions imposed by the copyright holders, this
corpus is available to 1998 LDC members only. Members who wish
to receive this corpus must sign the 1997 Mandarin Broadcast
News license. This license can be retrieved from the LDC
website at:

Message 2: Voicemail Corpus - Part I

Date: Tue, 29 Sep 1998 12:12:24 EDT
From: LDC Office <ldcunagi.cis.upenn.edu>
Subject: Voicemail Corpus - Part I


	Announcing a NEW CORPUS from the LDC

*************************
Voicemail Corpus - Part I
*************************


The Voicemail Corpus - Part I was created by the following
researchers at IBM:

M. Padmanabhan, G. Ramaswamy, B. Ramabhadran, P.S.
Gopalakrishnan, and C. Dunn. 

This CD-ROM corpus consists of 1801 voicemail messages,
collected from volunteers at various IBM sites in the United
States, comprising the training data set and 42 messages in the
development test set. The average voicemail message is 31
seconds in duration, and has about 100 words. Approximately 38%
of the messages correspond to male speakers; the remainder
correspond to females. All messages were transcribed by IBM. 

During the collection period, volunteers were asked to forward
some of their voicemail messages to a local extension number set
up for the purpose of collecting this data. The messages were
then collected periodically from the voicemailbox of this local
extension and added to the database.

DirectTalk6000 (DT6K) software was used to transfer the
voicemail messages to the computer. DT6K is an application that
runs under the AIX operating system on a host computer, and can
interface to a phone line through special hardware on the host
computer. Note that the data was collected from IBM sites all
over the US whereas the host computer that the DT6K application
was running on was located at a single IBM site. Consequently,
when the application dialed into the phonemail system of an IBM
site in a different state, the voicemail messages were played
out over a long distance line before they were recorded on the
host computer.

The data was sampled at 8 KHz, and recorded in 8-bit u-law
compressed format onto a local disk of the host computer. The
messages were compressed by the proprietary compression
techniques used by the ROLM phonemail system, which is the
phonemail system in use at various IBM locations.

IBM would like to acknowledge the support of DARPA for funding
this data collection effort under Grant MDA972- 97-C-0012 and is
also extremely grateful to George di Simone and Ira Ellis
(Watson telephone system support) for their help in setting up
the data collection process. IBM would also like to thank Dr. 
Ellen Eide for helping with the verification of transcripts and
Dr. Salim Roukos, Dr. David Nahamoo, and Dr. Lalit Bahl for
their help and support. Finally, thanks are due to the various
volunteers who contributed their voicemail messages to the
database. 

Institutions that have membership in the LDC during the 1998
Membership Year will be able to receive this corpus in the same
manner as all other text and speech corpora published by the
LDC.

Message 3: 1998 Speaker Recognition Evaluation Test-Set

Date: Tue, 29 Sep 1998 12:10:48 EDT
From: LDC Office <ldcunagi.cis.upenn.edu>
Subject: 1998 Speaker Recognition Evaluation Test-Set



	Announcing a NEW CORPUS from the LDC

********************************************
1998 Speaker Recognition Evaluation Test-Set
********************************************

The 1998 speaker recognition evaluation is part of an ongoing
series of yearly benchmark tests conducted by NIST. These
tests are intended to provide a stable reference point for
measuring and comparing the performance of diverse methods for
text-independent speaker recognition over the telephone, and
should be of interest to all researchers working in this area
of speech technology development. The test sets and
evaluation protocols have been designed to be simple, to focus
on core technology issues, to be fully supported, and to be
accessible.

In 1996 and 1997 handset variation was featured as a prominent
technical challenge to be addressed. While handset variation
remains a formidable challenge, the 1998 evaluation directs
greatest attention toward speaker recognition performance for
the case in which both training and test data are from the
same source. The speech data were recorded by the LDC between
January and March, 1997; most of the speakers recruited for
this collection were college students from the Great Lakes
(Northern Mid-West) region of the U.S.

Institutions that have membership in the LDC during the 1998
Membership Year will be able to receive this corpus in the
same manner as all other text and speech corpora published by
the LDC. Nonmembers may purchase the 1998 Speaker Recognition
Evaluation Test-Set for $600.

If you would like to order a copy of this corpus, please email
your request to <ldcunagi.cis.upenn.edu>. If you need
additional information before placing your order, or would
like to inquire about membership in the LDC, please send email
or call (215) 898-0464.

Message 4: JURIS (Justice Department Retrieval and Inquiry System) Text Corpus

Date: Tue, 29 Sep 1998 12:12:59 EDT
From: LDC Office <ldcunagi.cis.upenn.edu>
Subject: JURIS (Justice Department Retrieval and Inquiry System) Text Corpus



	Announcing a NEW CORPUS from the LDC

*******************************************************************
JURIS (Justice Department Retrieval and Inquiry System) Text Corpus
*******************************************************************

The text data contained on this two-CD-ROM set
represent a release of the JURIS (Justice Department
Retrieval and Inquiry System) data collection that
has been made available to the Linguistic Data
Consortium (LDC) by the U.S. Department of Justice. 
The time span of the text ranges from the 1700's to
the early 1990's.

There are 1664 individual text files in the corpus,
1011 on the first CD-ROM, and 653 on the second. The
original archive consisted of 219 files ranging
between less than 1 MB and nearly 70 MB in size. In
order to make the data more accessible for research
use, we chose to divide the larger files into pieces,
such that the average file size was about 2 MB when
uncompressed (the largest uncompressed file size is
about 4.5 MB). Divisions of the files were done at
document boundaries, so all files contain whole
documents.

There are a total of 694,667 document units in the
corpus, and these can be categorized to some extent
with regard to their content. The following is a
