Abstract

The present invention is applicable to the field of computer technology, and provides a voice verification method, device, computer equipment and storage medium. The voice verification method includes the following steps: obtaining voice information to be verified; Describe the effective voice information in the voice information to be verified; based on the preset linear prediction function, extract the voiceprint vocal organ feature vector of the effective voice information, and determine it as the voiceprint vocal organ feature model to be verified; obtain at least one Preset voiceprint vocal organ feature comparison model, and determine the voiceprint vocal organ feature comparison model with the largest logarithmic likelihood function value of the voiceprint vocal organ feature model to be verified; according to the logarithmic likelihood function The voiceprint vocal organ feature comparison model with the largest value determines the voice verification result. The voice verification method can improve the accuracy of voice verification and is applicable to text-independent voiceprint recognition.

Description

Technical field [0001] The invention belongs to the field of computer technology, and more particularly to a speech verification method, a device, a computer device, and a storage medium. Background technique [0002] People's voice contain semantic information and speaker information, which contains the ingredients of speaker information, called "sound", just like fingerprints, belongs to biometric information. In terms of popularity, the sound pattern is a generality of speech sound wave maps with speaker language feature information. In the language circulation, it is called a language in judicial identification, and people are called sound pattern than the reference fingerprint. As a "visible language" or "second fingerprint". The use of voiced graphics is known as sound pattern recognition, also known as speaker recognition. [0003] Voice identification technology is an analytical process for analyzing speaker speech signals, and performs a personal identification technolog...
