An improved method for voiceprint recognition

Abstract

In order to ensure the safety of the cloud, voiceprint recognition technology (VPR) has been more and more widely used. Voiceprint recognition technology judges the identity of the speaker according to the acoustic features of him or her. Therefore, if people have the accurate voiceprint recognition technology, then they can obtain the speaker’s identity information accurately. And it is obvious that the accurate voiceprint recognition technology has important significance for improving the performance of cloud security. However, there is relationship between the accuracy and the intensity of the interference signal of voiceprint recognition. To suppress the interference signal’s strength can improve the accuracy of voiceprint recognition. Based on this, the method of microphone array is selected to suppress the interference in the environment. The author hope that this method can significantly suppress the interference signals in the environment, in order to improve the accuracy of voiceprint recognition. The experimental results show that this method can realize the purpose of interference suppression. Besides, it plays a role in improving the accuracy of voiceprint recognition. In conclusion, this VPR method based on microphone array noise reduction has achieved higher accuracy, which can enhance cloud security.
