The invention comprises a method and apparatus for predicting word accuracy. Specifically, the method comprises obtaining an utterance in speec h data where the utterance comprises an actual word string, processing the utterance for generating an interpretation of the actual word string, processing the utterance to identify at least one utterance frame, and predicting a wor d accuracy associated with the interpretation according to at least one stationary signal-to-noise ratio and at least one non-stationary signal to noise ratio, wherein the at least one stationary signal-to-noise ratio and the at least o ne non-stationary signal to noise ratio are determined according to a frame energy associated with each of the at least one utterance frame.
