The TED-LIUM corpus was made from audio talks and their transcriptions
available on the TED website. We have prepared and filtered these data
in order to train acoustic models to participate to the International
Workshop on Spoken Language Translation 2011 (the LIUM English/French
SLT system reached the first rank in the SLT task).

Contains 1495 talks and transcripts.

This new TED-LIUM release was made through a collaboration between the
Ubiqus company and the LIUM (University of Le Mans, France)

Contents:

- 2351 audio talks in NIST sphere format (SPH), including talks from
  TED-LIUM 2: be careful, same talks but not same audio files (only
  these audio file must be used with the TED-LIUM 3 STM files)
- 452 hours of audio
- 2351 aligned automatic transcripts in STM format
- TEDLIUM 2 dev and test data: 19 TED talks in SPH format with
  corresponding manual transcriptions (cf. 'legacy' distribution below).
- Dictionary with pronunciations (159848 entries), same file as the one
  included in TED-LIUM 2
- Selected monolingual data for language modeling from WMT12 publicly
  available corpora: these files come from the TED-LIUM 2 release, but
  have been modified to get a tokenization more relevant for English
  language

Two corpus distributions:
- the legacy one, on which the dev and test datasets are the same as in
  TED-LIUM 2 (and TED-LIUM 1).
- the 'speaker adaptation' one, especially designed for experiments on
  speaker adaptation.
