System and Method for Efficiently Reducing Transcription Error Using Hybrid Voice Transcription
First Claim
1. A system for efficiently reducing transcription error via hybrid voice transcription, comprising:
- a parser to parse a voice stream from a call into utterances and assigning an initial transcribed value and corresponding recognition score to each utterance;
a message generator to generate a transcribed message for the call comprising the initial transcribed values;
a threshold module to apply a threshold to the recognition scores to identify those utterances with recognition scores below the threshold as questionable utterances;
a comparison module to compare at least one questionable utterance to other questionable utterances from other calls and forming a group of similar questionable utterances; and
an assignment module to select one or more of the similar questionable utterances from the group, to receive a common manual transcription value for the selected similar questionable utterances, and to assign the common manual transcription value to the remaining similar questionable utterances in the group.

Abstract
A system and method for efficiently reducing transcription error using hybrid voice transcription is provided. A voice stream is parsed from a call into utterances. An initial transcribed value and corresponding recognition score are assigned to each utterance. A transcribed message is generated for the call and includes the initial transcribed values. A threshold is applied to the recognition scores to identify those utterances with recognition scores below the threshold as questionable utterances. At least one questionable utterance is compared to other questionable utterances from other calls and a group of similar questionable utterances is formed. One or more of the similar questionable utterances is selected from the group. A common manual transcription value is received for the selected similar questionable utterances. The common manual transcription value is assigned to the remaining similar questionable utterances in the group.

11. A system for hybrid voice transcription error reduction, comprising:
-
a parser to parse a call into speech utterances; a message generator to generate a transcribed message for the call by assigning an initial transcribed value and corresponding recognition score to each utterance; a threshold module to apply a confidence threshold to the recognition scores and to select those utterances with initial transcribed values that fall below the threshold as questionable utterances; a sample module to generate a sample for at least one of the questionable utterances comprising identifying other questionable utterances from other calls that are similar to the at least one questionable utterance, grouping the at least one questionable utterance and similar questionable utterances as related utterances, and selecting one or more of the related utterances as the sample; and a module to receive a common manual transcription value for each of the related utterances in the sample and assigning the common manual transcription value to the remaining related utterances in the group. - View Dependent Claims (12, 13, 14, 15)
