Voiceprint-based target person recognition method, system and device and storage medium

Abstract

The invention discloses a voiceprint-based target person recognition method, system and device and a storage medium, wherein the method comprises the steps: obtaining a to-be-compared audio containing the speaking of a target person, obtaining a corresponding first voiceprint feature, searching a voiceprint feature library for similar voiceprint features, determining a plurality of similar audios, searching in a voiceprint information library according to the encrypted file names of the similar audios, and determining audio information corresponding to the similar audios, wherein the audio information comprises a mobile phone number of a speaker in the similar audios. According to the voiceprint-based target person recognition method provided by the embodiment of the invention, an investigation department can determine the mobile phone number of a person possibly being the target person according to the audio of the target person, so that the effect of narrowing the investigation range or carrying out key monitoring on the target person is achieved.

Description

technical field [0001] The present application relates to the field of voiceprint recognition, in particular to a method, system, device and storage medium for target person recognition based on voiceprint. Background technique [0002] With the development of communication technology, mobile terminals such as mobile phones have become very popular. While enjoying the convenience brought by mobile communication, people are also threatened by telecommunications network fraud. Vulnerable groups such as children commit fraud, and criminals often change multiple mobile phone cards of different operators when committing fraud, which makes it difficult for relevant departments to detect criminals' relevant information. In more new types of illegal and criminal activities, criminals may directly commit fraud through social platforms or chat software without leaving personal information such as mobile phone numbers, making it more difficult for relevant departments to investigate. ...

While enjoying the convenience brought by mobile communication, people are also threatened by telecommunications network fraud. Vulnerable groups such as children commit fraud, and criminals often change multiple mobile phone cards of different operators when committing fraud, which makes it difficult for relevant departments to detect criminal information

In more new types of illegal and criminal activities, criminals may directly commit fraud through social platforms or chat software, without leaving personal information such as mobile phone numbers, and it is becoming more and more difficult for relevant departments to investigate

[0003] In related technologies, there is a solution to trace the identity information of the target person through voiceprint recognition technology. However, since the identification and query systems owned by each operator are independent of each other, it is difficult to link them in actual work. Therefore, the investigation and law enforcement work of relevant departments limited help
