Speaker confirmation method and device based on residual time delay network, equipment and medium

Abstract

The invention discloses a speaker confirmation method and a speaker confirmation device based on a residual time delay network, equipment and a medium. The method comprises the steps of constructing the residual time delay network, and carrying out the training of the residual time delay network; acquiring a registered audio and a test audio of a test user; preprocessing the registered audio and the test audio, and then performing feature extraction to obtain the Mel-frequency cepstrum coefficients of the registered audio and the test audio respectively; transmitting the Mel-frequency cepstrumcoefficient of the registered audio / test audio to the trained residual time delay network, and obtaining a feature vector output by the residual time delay network at a session slice level as a registered feature vector / to-be-tested feature vector; and inputting the registration feature vector and the to-be-tested feature vector into a probability linear discriminant analysis model, and outputting a speaker confirmation result according to a score output by the model. The problem that an existing text-independent speaker confirmation method is poor in accuracy in the aspect of short audios issolved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a speaker confirmation method, device, equipment and medium based on a residual time delay network. Background technique [0002] Voiceprint recognition, also known as speaker recognition, is a kind of biometric technology. Voiceprint recognition mainly solves two types of problems, namely speaker identification and speaker confirmation. Speaker recognition technology is used to judge which of several speakers a certain voice comes from, which is a "many choice one question", while speaker confirmation technology is to determine whether a certain voice belongs to the designated person to be detected. "One-to-One Questions". The speaker confirmed that it is widely used in many fields, and has a wide range of needs in industries and departments such as banking, non-bank finance, public security, military and other civilian safety certification. [0003] Speaker conf...
