Abstract

The invention is applicable to the technical field of computers, and provides a voice verification method and device, computer equipment and a storage medium. The voice verification method comprises the steps that voice information to be verified is acquired; based on a preset effective information extraction method, effective voice information in the voice information to be verified is extracted;based on a preset linear prediction function, a voiceprint sounding organ feature vector of the effective voice information is extracted to be determined as a voiceprint sounding organ feature modelto be verified; at least one preset voiceprint sounding organ feature comparison model is obtained, and a voiceprint sounding organ feature comparison model with the maximum log likelihood function value is determined from the voiceprint sounding organ feature model to be verified; and a voice verification result is determined according to the voiceprint sounding organ feature comparison model with the maximum log likelihood function value. The voice verification method can improve the accuracy of voice verification, and can be applied to text-independent voiceprint recognition.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a voice verification method, device, computer equipment and storage medium. Background technique [0002] Human speech contains semantic information and speaker information, and the component containing speaker information is called "voiceprint", which belongs to biometric information just like fingerprints. In layman's terms, voiceprint refers to the general term for the speech sound wave spectrum that carries the speaker's language feature information. It is called a language map in the linguistics field. As a person's "visible language" or "second fingerprint". The method of using voiceprint for identity authentication is called voiceprint recognition, also known as speaker recognition. [0003] Voiceprint recognition technology is an identification technology that analyzes and processes the speaker's voice signal, and identifies the speaker's identity accordin...
