# This table defines the mapping used by the binary merge-vads to 
  # combine the output of compute-vad and compute-vad-from-frame-likes.
  # The first column corresponds to VAD decisions from compute-vad
  # and the second corresponds to VAD decisions from
  # compute-vad-from-frame-likes.  The labels "0" and "1" in the
  # first column represent (approximately) silence and nonsilence
  # respectively.  The labels "0," "1," and "2" in the second column
  # represent noise, speech, and music, respectively.  The third
  # column lists the resulting output labels: "0," "1," and "2" 
  # corresponding to silence/noise, speech, and music.
