Abstract
A method and device for fusing voiceprint features. The method includes: obtaining at least two voiceprint features of a voice sample of a target speaker (S3; S4); fusing the at least two voiceprint features on the basis of linear discriminant analysis (S5). The present method introduces a technique employing linear discriminant analysis to fuse various voiceprint features, so as to improve complementarities between the various voiceprint features and distinctions between the fused features, thereby increasing the recognition rate for target speakers and reducing the misrecognition rate for non-target speakers in voiceprint authentication scenarios, and providing personalized and improved user experience.
