    Hi, Daniel Povey

    I run this command "online-audio-server-decode-faster" at server, and i run this command "online-audio-client --htk --vtt localhost 5010 scp:test.scp" at client.

    So, i can get the result and time information.

    But i want to get alignment score.

    So, How can i get the alignment score by kaldi recognizer? thanks.

      You would have to change the code; you can do something like

           decoder.GetBestPath(&out_fst);

      Lattice::Weight total_cost = fst::ShortestDistance(out_fst);
      BaseFloat graph_cost = total_cost.Value1(),
          acoustic_cost = total_cost.Value2();

    Hi, Daniel Povey

    Thanks.

    The score get from acoustic model.

    But i dont have transfer the standard answer from client to server.

    I want to ask how to do transmission of wav data and the answer from client to server.

    And then, i can get the score of alignment from server. Thanks.

    Hi, Daniel Povey

    Sorry, my english is very poor.

    Such as htk, the cammand "HVite -l * -b silence -C config -a -H hmm7/macros-i aligned.mlf -m -t 250.0 -y lab -I words.mlf -S train.scp dict monophones1" can get some information. The information contain time information, phone, alignment score and word.

    An example of the results is as follows:

    !MLF!

    "*/F110101_0_01.lab"
    0 480000 sil -218.591125 k00000000
    480000 1440000 j -454.224609 k00000001
    1440000 3840000 in -1066.226440
    3840000 5280000 sh -701.459900
    5280000 7520000 eng -1081.869141
    7520000 10080000 er -1328.646362 k00000002
    10080000 11200000 h -573.749634
    11200000 13600000 ao -1128.040161

    How do i get the similar result in online recognizers at kaldi? Thanks.

      I think what you're talking about is aligning transcribed data.
      The top-level script you should look at is steps/align.sh or
      steps/align_si.sh, although the output it produces (e.g.
      exp/tri4a_ali/ali.1.gz) is also produced by the standard training scripts
      such as steps/train_lda_mllt.sh.
      The program show-alignments can be used to view the alignments in a
      human-readable form, and ali-to-phones has various options for converting
      it to phones in a more computer-readable form; you might find the command
      utils/int2sym.pl -f 2- data/lang/phones.txt < (input) > (output) useful
      here.
