A method of recognizing speech, comprising: presenting an utterance to a speech recognition system; determining, via the speech recognition system, that the utterance contains a particular expression, the particular expression capable of being associated with at least two different meanings; splitting the utterance into a plurality of speech frames, each frame being assigned a predetermined time segment and a frame number; indexing the utterance to i) a predetermined frame number, or ii) a predetermined time segment, the indexing identifying that one of the plurality of frames includes the particular expression; and re-presenting the one of the plurality of frames including the particular expression to the speech recognition system to verify that the particular expression was actually recited in the utterance.
