• responsive to the transcription confidence score being below a threshold, comparing, by the one or more processors, phonemes in the utterance to phonemes in at least one term from a high frequency term list;
• generate a sounds similar score for phonemes in the at least one terms from a high frequency term list, based on the comparing;
• and
• replace the transcription with the at least one term from the high frequency term list, if the sounds similar score is above a threshold.
