Title:
VOICEPRINT RECOGNITION METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/107810
Kind Code:
A1
Abstract:
Provided are a voiceprint recognition method and apparatus, and an electronic device and a medium, wherein same are applicable to the technical field of identity authentication. The method comprises: pre-processing an input voice to acquire a valid voice in the voice; extracting an MFCC acoustic feature of the voice and outputting first and second feature matrices containing an MFCC dimension and a voice framing number; constructing a long short-term recurrent neural network model and taking the first feature matrix as an input; training feature extraction matrices by using a training parameter of the neural network model and a speaker feature of the voice, with each of the feature extraction matrices corresponding to one speaker model; and selecting a speaker model matching the second feature matrix, with a speaker output corresponding to the matching speaker model being a voiceprint recognition result. Thus, a more appropriate acoustic feature can be mined from a training voice, so that the distinguishing features of speakers can be recognized more accurately, a speaker model with higher robustness can be learnt, and a better voiceprint recognition result can be acquired.
