11. A computer-implemented method for transcription error reduction, comprising the steps of: assigning a transcribed value and a confidence score to each utterance in a stream of audio data; identifying those utterances with confidence scores that fall below a confidence threshold as questionable utterances; placing at least one of the questionable utterances into a pool of related utterances also determined to be questionable; determining whether the pool satisfies a size threshold within a predetermined amount of time; obtaining a sample of the questionable utterances in the pool when the pool satisfies the size threshold within the predetermined amount of time; and providing the sample of questionable utterances to at least one human transcriber for verification, wherein the steps reduce an amount of manual transcription required by a transcription system.
