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
The present invention relates to biological characteristic and distinguish the field, be specifically related to a kind of method of utilizing simple arithmetic to carry out the checking of Chinese vocal print.
Background technology
The vocal print checking is the mode according to personal voice biological characteristic uniqueness identity verification.The vocal print checking has registration (Voice Enrollment) and checking (Voice Verification) two links.The correlativity of the content of saying during with registration according to when checking, the vocal print verification technique is divided into the relevant uncorrelated mode with text of mode (Text-Dependent) (Text-Independent) two of text class greatly; Whether its Chinese version relevant (Text-Dependent) content of speaking during according to checking is consistent during fully with registration, is divided into classics (Classic) pattern and points out (Text-Prompted) pattern at random.
The speech data that the uncorrelated mode of text (Text-Independent) need be gathered when registration is more; The user voice data that needs during checking is also more; The process of simultaneous verification is also long, and the backstage that generally is applied in user and the manual position communication process is detected.This mode is not suitable for real-time and requires situation high, that user's vocal print password is short.
The be correlated with classical mode (Classic) of mode (Text-Dependent) of text the time must be said identical content in checking, the security risk that the content that exists the user to speak is reset by the back of being recorded at every turn.Though vocal print checking manufacturer provides recording playback measuring ability; But what this recording playback measuring ability only detected is the content that the user once said in its system; And can there be the defective that can't all store greatly because of historical data in the playback measuring ability, and the playback measuring ability can't distinguish also the content of being recorded through which kind of channel is recorded.
The prompt modes at random (Text-Prompted) that text is relevant requires the user to say certain voice content when registration, when checking, randomly draw content please the user with reading, the randomness through content can solve the content playback problem.The general realization of the relevant prompt modes (Text-Prompted) at random of text is the checking of English digital string vocal print at present.When registration, can require the user to nine, to say four numerals (4-Digit Challenge/Response) at random from the zero of English; Like " six five nine two "; Can ask the user to say in the different permutation and combination of these four numerals during checking, like " nine five six two ".But because Chinese character syllable is shorter than english syllable, this kind mode is applied in the checking of Chinese vocal print and can causes vocal print authentication error rate FAR/FRR (False Accept Rate/False Reject Rate) to increase, and can't satisfy the accuracy rate requirement of vocal print checking.If increase the random number word string; When registration and checking, need the user to say more word; Though the error rate in the time of can improving the vocal print checking; But the user remembers not too easily and with reading a string random number word string that has no rule, causes memory disorders to the user the user when reading, and then reduces the user experience of vocal print checking.
Therefore, be necessary to provide a kind of method that realizes the checking of Chinese vocal print really, to overcome above-mentioned defective.
Summary of the invention
The technical matters that the present invention will solve is: a kind of method of utilizing simple arithmetic to carry out the checking of Chinese vocal print is provided, can guarantees the accuracy rate and the security of the checking of Chinese vocal print, and can be user-friendly to.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method of utilizing simple arithmetic to carry out the checking of Chinese vocal print is characterized in that may further comprise the steps:
1.. require the user to say zero carrying out vocal print when registration, and add, subtract, say one at random the multiplication and division, say at last to equal from the mathematical operation symbol to nine;
2.. when carrying out the vocal print checking, generate the simple algorithm topic at random, ask the user with reading, so that carry out the vocal print checking.
The invention has the beneficial effects as follows: the mathematical operation symbol that when carrying out the vocal print checking, adds when registering based on the user generates algorithm topic at random; Make the user carry out vocal print when checking many with the content of reading the at random prompt modes (Text-Prompted) more relevant with the character string of reading than text, content is long, thereby guaranteed the accuracy rate that vocal print is verified; And the algorithm topic that when checking, generates is fairly simple, and clear and definite relevance is arranged between numeral and the numeral, makes things convenient for the user to remember, thereby the user who improves the vocal print checking experiences.
