Embodiment Construction

[0028] The principles and embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Such as Figure 1 to Figure 3 As shown, the voiceprint-based verification method of the present invention includes two parts: registration and verification.

[0030] During registration, the present invention collects the user’s voice information and extracts the user’s voice features and stores them in the model library. When a specific individual user is registered, the user needs to speak at least twice as required for model training and extract the user’s biological Features, establish the user’s voice model and save it in the local model library. The present invention can specifically build a model for one or more users through the following steps.

[0031] (A) Wake up the verification device and then start registration;

[0032] (B) Record the current user, record at least twice, and obtain at least two voice messages as input s...

Abstract

The invention discloses a voiceprint-based verification method and device. The voiceprint-based verification method comprises the following steps of collecting voice information of at least one user,and extracting voice characteristics of the users to be stored in a model library; randomly generating verification passwords for reading by the users to be verified, and acquiring reading voices; extracting the contents to be verified and the voice characteristics in the reading voices, verifying the contents to be verified and the voice characteristics according to the model library and the verification passwords, and obtaining verification results. The method is a voiceprint recognition method based on local off-line processing; the recognized contents at each time are randomly changed; andverification voice signals are subjected to living body detection, so that the security of user verification is greatly improved.

Description

Technical field [0001] The present invention relates to identity verification technology, such as financial payment, access control, electronic lock equipment, etc., and particularly relates to voiceprint-based identity verification technology, and computer equipment and storage devices loaded with the identity verification technology. Background technique [0002] Voiceprint recognition is currently used in many fields. For example, in voice control, the user can speak a specified instruction to perform a corresponding action in response to the specified instruction. That is, the voice control is based on content. Some voice recognition is done by recording the audio in advance. After the same user speaks the audio of the same content, the recognition is passed. However, this kind of pre-recorded audio is easier to crack, and some cloud-based verification technologies require first Uploading voice to the network may be attacked by hackers in the process, so this voice recognitio...
