Computer-implemented system and method for reducing voice transcription error

摘要

A computer-implemented system and method for reducing voice transcription error is provided. Audio data is received during a call and parsed into utterances. A transcribed value and confidence score are assigned to each utterance. Those utterances with low confidence scores are identified as questionable utterances. One of the questionable utterances is selected from the audio data and a pool of questionable utterances is formed. The pool includes the selected questionable utterance and other questionable utterances, from other calls, that are similar to the selected questionable utterance. A size threshold is applied to the pool of questionable utterances. All the questionable utterances in the pool are provided to at least one human transcriber when the pool fails to satisfy the size threshold. Further transcribed values are received from the transcriber for each of the questionable utterances in the pool.

1. A computer-implemented system for reducing voice transcription error, comprising:
a mobile device configured to collect audio during a call, and configured to generate audio data from the collected audio; and a server comprising a central processing unit, memory, an input port that receives the audio data and an output port, wherein the central processing unit is configured to;
parse the audio data from the mobile device into utterances;assign a transcribed value and confidence score to each utterance;identify utterances with low confidence scores as questionable utterances;select one of the questionable utterances and form a pool of questionable utterances comprising the selected questionable utterance and further comprising other questionable utterances, from other calls, that have transcribed values similar to the transcribed value of the selected questionable utterance;apply a size threshold to the pool of questionable utterances;provide each questionable utterance in the pool to a human transcriber when the pool fails to satisfy the size threshold; andreceive from the human transcriber a further transcribed value for each of the questionable utterances in the pool.
