文章设计开发的基于声纹识别和语音识别的网络账号身份认证系统主要包含声纹录入、建库以及声纹判别两个部分。网络用户注册时，对用户的声纹进行采集；用户再次登录时，将用户的声纹与数据库中的声纹进行比较，通过声纹识别验证用户身份，确保用户的数据安全。系统建立在服务器端，安装方便快捷，安全性高。对用户要求低，仅需要一部麦克风即可完成注册。系统操作方便、简单，安全性、保密性好，市场前景广阔。

英文摘要：

The network account identity authentication system based the voiceprint recognition and the speech recognition proposed and designed in this paper includes the voiceprint entry and database construction model and the voiceprint discriminant model. When the user registers, the system collects the user＇s voiceprint. When the user registers again, the system compares the user＇s voiceprint with voiceprints in the database, validating the user＇s identity through voiceprint recognition to ensure the data security of users. The system is built on the server side with convenient installation and high security.The system has low request to the users, only needs a microphone to complete registration. The operation on the system is convenient and simple ,with high security and confidentiality .The system has wide market prospect.
