Introduction
The Linguistic Data Consortium (LDC) at the University of Pennsylvania
distributes a wide and growing assortment of resources for researchers,
engineers and educators whose work is concerned with human languages.
Historically, most linguistic resources were not generally available to
interested researchers but were restricted to single laboratories or to
a limited number of users. Inspired by the success of selected, readily
available and well-known data sets, such as the Brown University text
corpus, LDC was founded in 1992 to provide a new mechanism for
large-scale corpus development and sharing of resources. With the support of its members, LDC is
able to provide critical services to the language research community.
These services include: maintaining the data archives, producing and
distributing data via media (DVD-ROM or CD-ROM) or web downloads,
negotiating intellectual property agreements with data providers and
maintaining relations with other like-minded groups around the world.
Resources available from LDC (http://www.ldc.upenn.edu) include speech,
text and video data and lexicons in multiple languages, as well as
software tools to facilitate the use of corpus materials. For a
complete view of LDCs publications, a searchable catalog is available
at
http://www.ldc.upenn.edu/Catalog/.
Data
The Asian Spoken Language Sampler provides a variety of speech and
transcript samples from various corpora and is designed to illustrate the variety and
breadth of the speech-related resources available from LDCs Catalog. Further information about each data set can be obtained by clicking the links in the table below.
The sample files provided in this release have been modified in various ways
relative to the original data as published by LDC:
-
most excerpts are truncated to be much shorter than the original
files, excerpt duration is typically one minute and thirty seconds
-
signal amplitude has been adjusted where necessary to normalize
playback volume
-
some corpora are published in compressed form, but all samples here
are uncompressed
-
LDC frequently uses NIST SPHERE file format for audio data, but the
audio files in this sampler have been converted to MS-WAV/audio
(RIFF) file format for compatibility with typical browser audio
utilities.

2005 NIST Language Recognition Evaluation
|
The goal of the NIST Language Recognition Evaluation is to establish
the baseline of current performance capability for language
recognition of conversational telephone speech and to lay the
groundwork for further research efforts in the field.
|
|
2007 NIST Language Recognition Evaluation Test Set
|
The most significant differences between previous NIST evaluations
and the 2007 task were the increased number of languages and
dialects, the greater emph asis on a basic detection task for
evaluation and the variety of evaluation conditions.
