##Building against Kaldi

OpenDcd has a set of Kaldi interoperability tools and the decoder can built against a Kaldi to give full to all for the Kaldi libraries. Building against Kaldi is extremely simple:

export KALDI_ROOT=/path/to/kaldi-trunk/
cd  opendcd/src/kaldibin
make

This process will build the following:

  • dcd-recog-kaldi - The main decoding command
  • make-arc-types - Tool to build the arcs
  • lattice-to-far - Convert a Kaldi lattice archieve to OpenFst far format
  • lattice-filter - Apply a series of OpenFst commands to every lattice in an ark
  • split-self-loop-states - Split self loops in HCLG cascade without explicitly adding the loops
