Voice information verification method and device, electronic equipment and medium

Abstract

The invention relates to a voice processing technology, and discloses a voice information verification method, which comprises the steps of performing voice recognition, data labeling, text enhancement and probability calculation on an original voice data set to obtain a classification probability value and calculate a cross entropy loss value with a real probability value, and when the cross entropy loss value is smaller than a loss threshold, obtaining a standard text detection model; and performing probability calculation on the to-be-processed voice data, obtaining a prediction probabilityvalue set, summarizing the prediction probability values greater than a probability threshold, obtaining a prediction result list, extracting categories corresponding to the prediction probability values, and when the number of the categories is greater than or equal to a preset number threshold, determining that the to-be-processed voice data passes verification. The invention also relates to ablockchain technology, and the training data set and the like can be stored in the blockchain node. The invention further discloses a voice information verification device, electronic equipment and astorage medium. According to the invention, the content contained in the voice can be quickly and accurately verified.

Description

technical field [0001] The invention relates to the technical field of voice processing, in particular to a voice information verification method, device, electronic equipment and computer-readable storage medium. Background technique [0002] In some situations in life and work, recordings are made, and after the recording, whether the recording contains certain types of information is reviewed and checked. For example, when businesses communicate with users on the phone or face-to-face, they often record the content of the phone call or face-to-face conversation, and the verifiers judge whether the recording contains certain types of information. When the recording contains certain types of information, Determination of recording content as complete or incomplete when the recording does not contain certain categories of information. [0003] In the prior art, verification methods for this type of voice information often require the verification personnel to sort out keywo...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, verification methods for this type of voice information often require the verification personnel to sort out keywords, and then verify the voice information through keyword matching, but the process of keyword sorting is quite labor-intensive and inefficient , and because the keywords are often not exhaustive, if there is a lack of relevant keywords, the verification effect may not be accurate enough
