Computer-implemented system and method for masking special data |
| 摘要 |
A computer-implemented system and method for masking special data is provided. Speakers of a call recording are identified. The call recording is separated into strands corresponding to each of the speakers. A prompt list of elements that prompt the speaker of the other strand to utter special information is applied to one of the strands. At least one of the elements of the prompt list is identified in the one strand. A special information candidate is identified in the other strand and is located after a location in time where the element was found in the voice recording of the one strand. A confidence score is assigned to the element located in the one strand and to the special information candidate in the other strand. The confidence scores are combined and a threshold is applied. The special information candidate is rendered unintelligible when the combined confidence scores satisfy the threshold. |

1. A computer-implemented method for masking special data comprising:
identifying speakers of a voice recording; separating the voice recording into strands corresponding to each of the speakers, wherein one strand is associated with one of the speakers and another strand is associated with a different speaker; applying to one of the strands, a prompt list comprising elements that prompt a speaker associated with the other strand to utter special information; identifying at least one of the elements of the prompt list in the one strand using automatic speech recognition; identifying via the automatic speech recognition a special information candidate in the other strand directly after a location in time where the element was found in the voice recording of the one strand; assigning a confidence score to the element located in the one strand and to the special information candidate in the other strand; combining the confidence scores and applying a threshold to the combined confidence scores; and rendering utterances corresponding with the special information candidate unintelligible on a special purpose digital recorder when the combined confidence scores satisfy the threshold. |
