Embodiment 1

[0023] This embodiment provides a voiceprint verification method. figure 1 is a flow chart of the voiceprint verification method according to the first embodiment of the present invention. The execution subject of this embodiment is a terminal device.

[0024] Step S110, collecting voice information to be verified.

[0025] After the voiceprint verification function is started, the voice information input by the user is collected, and the voice information is the voice information to be verified. In this embodiment, the voice information may be a voice password input by the user.

[0026] Collecting voice information may include the following steps:

[0027] Step 1: Start the voiceprint verification function and prompt the user to input the voice password. The voice password can be a text or a number, and the user can read the text or number through a microphone.

[0028] Step 2, collect the voice password input by the user through the microphone. The voice signal is the...

Embodiment 2

[0045] A more specific embodiment is given below to illustrate the voiceprint verification method of the present invention.

[0046]In this embodiment, the voice waveform is firstly matched with the pre-stored standard voice waveform; if the waveform matching is successful, then the voiceprint features are matched with the pre-stored standard voiceprint features; otherwise, the voiceprint verification fails ; If the feature matching is successful, the voiceprint verification is passed, otherwise, the voiceprint verification is not passed. Of course, it is also possible to perform feature matching on the voiceprint feature and the pre-stored standard voice-print feature first; if the feature matching is successful, then perform waveform matching on the sound waveform and the pre-stored standard sound waveform, otherwise, the voiceprint verification fails; if the waveform If the matching is successful, the voiceprint verification is passed; otherwise, the voiceprint verification...

Embodiment 3

[0065] This embodiment provides a voiceprint verification device. image 3 is a structural diagram of a voiceprint verification device according to a third embodiment of the present invention. The apparatus in this embodiment may be set in a terminal device.

[0066] The unit includes:

[0067] The collection module 310 is used to collect voice information to be verified.

[0068] The extraction module 320 is configured to extract voiceprint features from the sound waveform corresponding to the voice information.

[0069] The verification module 330 is configured to perform waveform matching on the sound waveform and the pre-stored standard sound waveform, and perform feature matching on the voiceprint features and the pre-stored standard voiceprint features; if the waveform matching and the feature matching both match If successful, the voiceprint verification is passed.

[0070] In one embodiment, the collection module 310 is further configured to intercept a voice segme...

Abstract

The invention discloses a vocal print verification method and device. The method comprises the following steps of collecting voice information to be verified; in a sound waveform corresponding to thevoice, extracting vocal print features; performing waveform matching on the sound waveform and the prestored sound waveform; performing feature matching on the vocal print feature and the prestored standard vocal print features; if the waveform matching and the feature matching are both successful, recording that the vocal print verification is passed. The method and the method have the advantagesthat the vocal print features are subjected to matching verification; on the sound waveform, the vocal print verification can be regarded to be passed only when the two matching verifications are passed. Therefore even when the vocal print features of a user are viciously simulated, the condition that the vocal print features and the sound waveforms are simultaneously simulated cannot occur; theproblem of identity verification pass through vicious simulation of the vocal print features of the user can be solved by the method and the device.

Description

technical field [0001] The invention relates to the technical field of identity verification, in particular to a voiceprint verification method and device. Background technique [0002] With the gradual maturity of speech technology, many technologies such as speech recognition, TTS (Text To Speech, from text to language) synthesis, language recognition, and voiceprint recognition have been applied. Wherein, since the voiceprint is unique, after the voiceprint model is established, the user's identity can be verified by matching the voiceprint input by the user with the voiceprint model. [0003] Although the voiceprint is unique, malicious simulation cannot be avoided. For example, if the user's voiceprint is simulated by means of recording, it can successfully pass the identity verification, causing security risks. Contents of the invention [0004] The invention provides a voiceprint verification method and device, which are used to solve the problem that the voiceprin...
