1. A method, comprising: accessing a plurality of parameters for a speech recognition module, the plurality of parameters including feature extraction parameters and acoustic model parameters; applying an objective function to the speech recognition module to determine an objective function value based on the plurality of parameters; adjusting at least one of the feature extraction parameters and at least one of the acoustic model parameters to increase the objective function value; and providing an adjusted speech recognition module as a function of the adjustment of the at least one of the plurality of parameters.
