1. A computer-implemented system for transcription error reduction during a live call, comprising: a processor to execute modules, comprising: a transcription module configured to transcribe speech utterances from a speaker during a live call; a scoring module configured to assign a confidence score to each transcribed speech utterance from the live call; an identification module configured to identify one of the transcribed speech utterances with a low confidence score; a grouping module configured to attempt to generate a pool of related transcribed speech utterances for the identified transcribed speech utterance, comprising: a monitor submodule configured to monitor other speech utterances from other live calls for a predetermined amount of time; a similarity submodule configured to identify similar transcribed speech utterances with low confidence scores from one or more of the other live calls and to form a group comprising the identified similar transcribed speech utterances and the identified transcribed speech utterance; a group determination submodule configured to determine whether the group includes a predetermined number of transcribed speech utterances upon termination of the predetermined time; and a group designation submodule configured to designate the group as the pool when the group has at least the predetermined number of transcribed speech utterances within the predetermined time; and a sample processing module configured to process a sample of the transcribed speech utterances in the pool to verify a validity of the transcribed speech utterances in the sample and pool.
