Problems solved by technology

However, because Chinese syllables are shorter than English syllables, the application of this method in Chinese voiceprint verification will lead to an increase in the voiceprint verification error rate FAR/FRR (False Accept Rate/False Reject Rate), which cannot meet the accuracy requirements of voiceprint verification
If the random number string is increased, the user

Embodiment Construction

[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0014] figure 1 Disclose a flow chart of a method for verifying Chinese voiceprints using simple arithmetic in the present invention, the steps are as follows:

[0015] Step S101, when performing voiceprint registration, the user is required to say zero to nine, and randomly say one of the four basic mathematical symbols addition, subtraction, multiplication, and division, and say equal;

[0016] Step S102 , when performing voiceprint verification, the user is required to follow and read a randomly generated simple algorithm question, such as 11+12=23, to perform voiceprint verification.

[0017] The present invention uses simple arithmetic to verify the Chinese voiceprint. Compared with the text-related random mode (Text-Prompted), since the user s...

Abstract

The invention relates to a method for performing voiceprint verification of Chinese through single arithmetic. The method comprises the following steps that: when the voiceprint enrollment is performed, a user is required to speak from zero to nine, randomly speak one of arithmetic operation symbols, namely plus, minus, multiplication, division, and finally speak equal; and when the voiceprint verification is performed, the user is required to read after a randomly generated simple arithmetic problem for voiceprint verification. By the technical scheme, compared with a text-dependent random mode (Text-Prompted), the method has the advantages that: the arithmetic operation symbol is added during voiceprint enrollment, the content and character strings which are read after by the user during voiceprint verification are increased, and the accuracy rate of voiceprint verification of Chinese is improved; and the user reads after the simple arithmetic problem, and the definite correlation exists among figures so as to facilitate the memorization of the user, so that a user experience of the voiceprint verification can be improved.

Description

technical field [0001] The invention relates to the field of biological feature identification, in particular to a method for verifying Chinese voiceprints by using simple arithmetic. Background technique [0002] Voiceprint verification is a way to verify identity based on the uniqueness of personal voice biometrics. Voiceprint verification has two links: registration (Voice Enrollment) and verification (Voice Verification). According to the correlation between the content of verification and registration, voiceprint verification technology is divided into two categories: Text-Dependent and Text-Independent; Text-Dependent is based on Whether the speech content during verification is completely consistent with that during registration is divided into Classic mode and Text-Prompted mode. [0003] The text-independent mode (Text-Independent) needs to collect more voice data during registration, and requires more user voice data during verification. At the same time, the ver...
