摘要翻译：
识别系统通常被设计成在系统的访问控制级别对用户进行身份验证。许多使用基音估计的语音识别方法在低信噪比(SNR)环境中非常脆弱，因此这些程序不能提供所需的准确性和鲁棒性。此外，大多数与文本无关的说话人识别程序无法应对通过篡改样本或参考数据库来获得访问的未经授权的尝试。本文提出的与文本无关的语音识别系统利用多级密码技术来保持数据在传输或存储过程中的完整性。加密和解密采用基于变换的伪随机噪声叠加方法，而基音检测采用改进的自相关基音提取算法。实验结果表明，在信噪比不断增大的范围内，该算法能够以指数级减小均方误差的方式对待测信号进行解密。而且，在实际的识别任务中，即使在噪声环境中，它也优于传统的算法。将该方法与其它常用的说话人识别方法进行了比较。

英文摘要：
  Recognition systems are commonly designed to authenticate users at the access control levels of a system. A number of voice recognition methods have been developed using a pitch estimation process which are very vulnerable in low Signal to Noise Ratio (SNR) environments thus, these programs fail to provide the desired level of accuracy and robustness. Also, most text independent speaker recognition programs are incapable of coping with unauthorized attempts to gain access by tampering with the samples or reference database. The proposed text-independent voice recognition system makes use of multilevel cryptography to preserve data integrity while in transit or storage. Encryption and decryption follow a transform based approach layered with pseudorandom noise addition whereas for pitch detection, a modified version of the autocorrelation pitch extraction algorithm is used. The experimental results show that the proposed algorithm can decrypt the signal under test with exponentially reducing Mean Square Error over an increasing range of SNR. Further, it outperforms the conventional algorithms in actual identification tasks even in noisy environments. The recognition rate thus obtained using the proposed method is compared with other conventional methods used for speaker identification.
