System and method for detecting identity impersonation in telephone satisfaction survey

Abstract

The invention provides a system and a method for detecting identity impersonation in telephone satisfaction survey and provides a solution for the following problems: identity impersonation detection can be carried out only for single-channel telephone speech in previous telephone satisfaction surveys, the method for speech processing is rough, telephone survey speech contains a variety of non-effective speeches such as noise and ring-back tone, and the like. The system of the invention is composed of a to-be-detected speech library 101, a preprocessing module 102, a speaker speech segmentation module 103, a respondent voiceprint library 104, a voiceprint training module 105, a respondent speech database 106, a verification speech selection module 107, a respondent verification speech library 108, a voiceprint verification module 109, a score statistical analysis module 110 and a detection report generation module 111. Identity impersonation is detected by using the voiceprint recognition technology and the speaker speech segmentation technology, and a clear and readable identity impersonation detection report is given finally to be reflected on the authenticity of survey data in telephone satisfaction survey.

Description

technical field [0001] The invention relates to the technical field of voiceprint recognition, in particular to a system and method for detecting identity impersonation in telephone satisfaction surveys. Background technique [0002] In the telephone satisfaction survey, there is a situation that the survey object pretends to be one and many identities, that is, the survey object A pretends to be B, C, D and other identities in different telephone surveys. Such a situation will directly affect the credibility of the survey data and damage the interests of the commissioning party. Take the car user satisfaction survey as an example. One of the tasks of automakers in channel management is to conduct satisfaction surveys on dealers. The assessment results are directly related to the interests of dealers, because if the assessment scores are high, the manufacturers will give appropriate rebates to dealers. And some surveys of car owners who have conflicts with the dealer or ar...

Problems solved by technology

[0009] The present invention proposes a system and method for detecting identity impersonation in telephone satisfaction surveys, which solves the problem that identity impersonation detection in previous telephone satisfaction surveys can only detect single-channel telephone voices and the way of processing voices is relatively rough. There are many non-effective voice problems such as noise and ringback tone
