CMUSphinx with custom features


I'm trying to train a new accoustic model for speechrecognition, with custom features. Is it possible to feed the feature matrix instead of wav file into CMUSphinx for training? I have tried searching on google and the tutorial page and can't find any information about it. Am i missing something?

  • Is it possible to feed the feature matrix instead of wav file into CMUSphinx for training?

    It is better to train with more modern toolkit like Kaldi.

    You just prepare mfc files yourself and skip first feature_extraction step. You have to write code for that like described here:

    In kaldi you just prepare ark files yourself:
