Abstract：In the police wirelesscommunication system，there are information security risksdue to the lack of identity authentication mechanism forcommunicationterminal users.Therefore，this paper proposesavoiceprintauthenticationmethod for police wirelesscommunication systembased on ERes2NetV2.This method uses multi-scale residual structure to extract voiceprintfeatures，hichectivelyimprovestheaccuracyofviceprintrecognition.Inpolicecommunication，espealyinthe applicationscenariosoffastspechspeandshortspeechduratio，itsowsgoodrobustnessExperimetsarecarredoutonthe speech datasetof the actualpolicelaw enforcementscene.Theresultsshowthatthe voiceprint matching acuracyofthis method canreach 96.0% .Atthe same time，combined with theabnormal voiceprint alarm mechanism，itcan provide amoreeconomical and efficient safety control method for the safety protection of police systems.
