Cloud voiceprint recognition system and method for community access control

Abstract

The invention provides a cloud voiceprint recognition system and method for community access control. The method is characterized in that a user inputs a preset voiceprint password through a user terminal, and after successful voice recognition, the preset voiceprint password is transmitted to a cloud server for processing and storage; and then, the user can speak out a check voiceprint password at an access controller, and the access controller carries out voice recognition and voiceprint acquisition, and then, transmits the check voiceprint password to the cloud end for voiceprint modeling processing and comparison, and recognition is carried out by utilizing powerful computation ability of the cloud end. When the preset voiceprint password and the check voiceprint password are collected, voice recognition is carried out to improve recognition efficiency; and legality of the voiceprint is verified through asymmetric error rate, so that the user can pass through the access control more smoothly, and each opening action and record can be obtained. The method and system provide basis for deploying a voiceprint recognition system in a community in a large area, so that user learningcost is low, construction-side installation cost is low and operation-side maintenance cost is low, and passage convenience and passage efficiency of community access control can be improved effectively.

Description

technical field [0001] The invention relates to the field of community access control based on voiceprint recognition, in particular to a cloud voiceprint recognition system and method applied to community access control. Background technique [0002] At present, there are many kinds of access control products on the market, which can be divided into card swiping and biometrics in terms of application technology. Card swiping mainly includes magnetic cards, bar cards and IC cards, etc. Biometrics includes fingerprint access control, iris access control, etc.; Pedestrian passages and building unit doors are not private access control and have a semi-open nature, while fingerprint recognition, palmprint recognition, iris recognition and face recognition are private and do not match; traditional methods require users to bring keys, access cards or use It is inconvenient for community owners to open the door through the intercom. [0003] Voiceprint is the sound wave spectrum t...

Problems solved by technology

[0004] However, the traditional voiceprint recognition access control system is a closed system in consideration of security issues. Generally, only the access control controller and the host computer are required. Local range, and there are also defects such as inconvenient voiceprint recording, relatively fixed voiceprint, and low recognition efficiency. Moreover, traditional voiceprint recognition often directly performs voiceprint modeling and feature extraction. Whether it is input or comparison, text Relevant recognition also needs to complete all the calculation steps. It is not only inconvenient for users to use, but also increases the calculation amount of voiceprint recognition. The poor usability, low recognition rate and closed technical attributes seriously hinder the voiceprint recognition. Application of Identification Technology in Public Access Control

[0005] For the community, people usually don’t care about the illegal opening of pedestrian access control and unit access control. Relatively speaking, they pay more attention to the convenience and efficiency of traffic. The traditional local voiceprint modeling form has low recognition efficiency, closed system and Defects such as single function are not suitable for community access control, and the voiceprint application in the community needs to be improved and designed according to the application characteristics of the community. Therefore, this application proposes a cloud voiceprint recognition system for community access control and its method
