    Hey,

    I've successfully used the -kws in pocketsphinx with good results but I need to train my own model for 5 words using shinxtrain.
    My database is not huge and is manually collected.
    First issue I ran into was the "not enough data" so I duplicated my database to reach the required 1 hour.
    But still I got bad accuracy:
    TOTAL Words: 1260 Correct: 396 Errors: 864
    TOTAL Percent correct = 31.43% Error = 68.57% Accuracy = 31.43%

    Is there a special way to train small models for few words?

    PS: I cannot use model adaptation.

    Thanks.
