This paper describes the release of a set of English translations (obtained on Amazon's Mechcanical Turk) and ASR lattice output (produced with Kaldi). Together, this data supplements existing LDC datasets (in the form of audio and Spanish transcriptions), yielding a four-way parallel corpus for research in Spanish–English spoken language translation.

The LDC datasets that this dataset extends are as follows:

Audio Transcripts
Fisher Spanish LDC2010S01 LDC2010T04
CALLHOME Spanish LDC96S35 LDC96T17
