This paper investigates the use of discriminative schemes based on the maximum mutual information (MMI) and minimum phone error (MPE) objective functions for both task and gender adaptation. A method for incorporating prior information into the discriminative training framework is described. If an appropriate form of prior distribution is used, then this may be implemented by simply altering the values of the counts used for parameter estimation. The prior distribution can be based around… CONTINUE READING
