    First of all, s2 supports several model types

    • s2-specific models (with chmm files like the default s2 one). the tool to convert semi-cont model to such format is available in old sphinxtrain

    https://sourceforge.net/projects/cmusphinx/files/sphinxtrain/1.0/SphinxTrain-
    1.0.tar.bz2/download

    • semi-continuous models as trained by today sphinxtrain with default setup
    • continuous models as trained by today sphinxtrain with default setup

    However, if you are talking about default hub4_wsj_8k model, you will not be
    able to use it because it uses specific feature extraction methods which are
    not supported by s2 (transform dct). Also it uses sendump file in specific
    format not supported s2. You need to get the version of this model with
    mixture weights.
