16. The non-transitory computer readable medium of claim 14 , wherein the processing the utterance to identify the utterance frame, comprises: aligning the utterance to the interpretation; partitioning the utterance into the utterance frame; and classifying the utterance frame as one of: a speech frame or a silence frame.
14. A non-transitory computer readable medium storing a software program, that when executed by a computer, causes the computer to perform operations, the operations comprising: obtaining an utterance in speech data, wherein the utterance comprises an actual word string; processing the utterance for generating an interpretation of the actual word string; processing the utterance to identify an utterance frame; and calculating a prediction of a word accuracy associated with the interpretation based on a stationary signal-to-noise ratio and a non-stationary signal-to-noise ratio, wherein the stationary signal-to-noise ratio and the non-stationary signal-to-noise ratio are determined according to a frame energy associated with the utterance frame, and wherein the calculating comprises: computing the stationary signal-to-noise ratio for the utterance; computing the non-stationary signal-to-noise ratio for the utterance; and computing the prediction of the word accuracy associated with the interpretation using the stationary signal-to-noise ratio and the non-stationary signal-to-noise ratio.
