Antiterrorist forewarning method and device based on telephone monitoring

Abstract

The invention provides an antiterrorist forewarning method and device based on telephone monitoring. The antiterrorist forewarning method comprises the steps that communication voice of a monitored user is obtained; to-be-verified voiceprint information in the communication voice is extracted, the to-be-verified voiceprint information is compared with preset voiceprint information in a voiceprintlibrary, wherein the preset voiceprint information is voiceprint information of prerecorded voice of a target suspect in a preset case; and after the monitored user is determined as the target suspectaccording to the comparison result, voice contents in the communication voice are extracted through a semantic recognition technology, whether the voice contents are related to the preset case or notis judged, and if yes, forewarning is executed. According to the antiterrorist forewarning method and device based on telephone monitoring, whether the monitored user is the target suspect or not isdetermined through voiceprint recognition, if yes, the voice contents of the monitored user are extracted through semantic recognition, then the case involved by the target suspect is determined, antiterrorist forewarning can be achieved in time, manual operation is reduced, and the working efficiency and accuracy of case monitoring are improved.

Description

technical field [0001] The invention relates to the technical field of voiceprint recognition, in particular to a method and device for anti-terrorism early warning based on telephone monitoring. Background technique [0002] In the field of public security criminal investigation, telephone monitoring of criminal suspects has become a common technical means. The popularity of mobile terminals has led to more and more mobile phone users, and the personal user information involved has become more and more complicated. Therefore, in In the process of telephone monitoring, determining the identity of the monitoring object becomes the focus. [0003] At present, the technology of telephone monitoring is carried out manually. If there are 10 suspects who need to be monitored manually during the investigation of a certain case, it will require a lot of manpower and time, and manual work cannot accurately confirm that the caller is a criminal suspect. In itself, it has caused certa...
