LDC-Online is a free service for LDC current year members.
An interactive tutorial is available to everyone, as is a guest account permitting access to the Brown text corpus, the TIMIT speech corpus and the Switchboard corpus.
All LDC text and speech resources are indexed for convenient online access, as long as no copyright or other restrictions prevent it. You can browse (where the copyright owner permits), or search by word, lemma or part-of-speech, or search with (limited) regular expressions combining these elements. Statistics such as word frequency and mutual information between words are also available.
Anyone from an LDC current year member organization has the right to access all the online resources. Because of our agreements with information providers, LDC-Online access is subject to the same individual user agreements that apply to access at the individual's own site.
To use LDC-Online, you need an individual user account. If you don't have an account yet, press here to get one. Even if your organization is not an LDC member, you can get a guest account with access to the Brown Corpus, the TIMIT speech corpus and Switchboard corpus.
For further information about LDC corpora, including some that are not yet available online, see the LDC Catalog or (for some cases) the available online documentation.
