About the Callhome Egyptian Arabic Corpus
  
    The CALLHOME Egyptian Arabic corpus of telephone speech consists of 120 unscripted 
    telephone conversations between native speakers of Egyptian Colloquial Arabic (ECA), 
    the spoken variety of Arabic found in Egypt. The dialect of ECA that this 
    dictionary represents is Cairene Arabic.
  
    This recipe uses the speech and transcripts available through LDC. In addition, 
    an Egyptian arabic phonetic lexicon (available via LDC) is used to get word to 
    phoneme mappings for the vocabulary. This datasets are:
  
    Speech : LDC97S45
    Transcripts : LDC97T19
    Lexicon : LDC99L22
  
  
  Each subdirectory of this directory contains the
  scripts for a sequence of experiments.
  
    s5: This recipe is based on the WSJ s5 recipe. It works with the 
        romanized version of the transcripts (available along with the
        script in LDC97T19). In addition, it uses a phonetic lexicon. 
        The recipe follows the Triphone+SGMM+SAT+fMLLR pipeline. It uses data
        partitions as specified by LDC in the corpora description.
