            This paper describes the release of a set of English translations (obtained
            on <a href="http://mturk.com">Amazon's Mechcanical Turk</a>) and ASR lattice output
            (produced with <a href="http://kaldi.sf.net">Kaldi</a>). 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&ndash;English spoken language
            translation. 
          </p>

          <p>
            The LDC datasets that this dataset extends are as follows:
