LDC (Linguistic Data Consortium) Spoken Language Sampler - Second Release contains samples from 20 different corpora published by LDC between 1996 and 2013.
LDC 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 or web downloads, negotiating intellectual property agreements with potential information providers and maintaining relations with other like-minded groups around the world.
Resources available from LDC include speech, text, video data and lexicons in multiple languages, as well as software tools to facilitate the use of corpus materials. For a complete view of LDC's publications, browse the Catalog.
This sampler is available as a free download.
The LDC Spoken Language Sampler - Second Release provides speech and transcript samples and is designed to illustrate the variety and breadth of the resources available from the LDC Catalog. The sound files included in this release are excerpts that 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, typically between 1.5 and 2 minutes.
- Signal amplitude has been adjusted where necessary to normalize playback volume.
- Some corpora are published in compressed form, but all samples here are uncompressed.
- Some text files are presented as images to ensure foreign character sets display properly.
- In some publications, NIST SPHERE file format is used for audio data, but the audio files in this sampler are MS-WAV/audio (RIFF) file format for compatibility with typical browser audio utilities. FLAC files have been expanded into their wav form as well.
