  • SphinxTrain 1.0 Released

    SphinxTrain is the acoustic model training system for the Sphinx family of continuous speech recognition systems.After years of not having an actual release of SphinxTrain, it was time to make one, in anticipation of potentially restructuring the training code. This trainer can produce acoustic models for all versions of Sphinx, and supports VTLN, speaker adaptation and dimensionality reduction.Future releases will support discriminative and speaker-adaptive training, and will be more closely integrated with the Sphinx decoders.
