In addition, in the description of the present invention, when it is determined that a detailed description of related commonly used technology may obscure the gist of the present invention, the description thereof will be omitted.

[0031] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0032] FIG. 1 is a control block diagram illustrating a voice verification and restriction method of a voice terminal according to an embodiment of the present invention, and is a diagram illustrating a voice storage procedure, and FIG. 2 is a control block diagram illustrating the voice verification and restriction method of the voice terminal according to the embodiment of the present invention, and is a diagram illustrating a voice verification procedure.

[0033] The illustrated figures are control block diagrams illustrating the voice verification and restriction method of the voice terminal according to the embodiment of the present invention, and include a) voice storage step and b) voice verification step.

[0034] First, as illustrated in FIG. 1, this figure is the control block diagram illustrating the voice verification and restriction method of the voice terminal according to the embodiment of the present invention. The voice storage procedure will be examined as follows. The a) voice storage step includes steps S10 to S12 of inputting and registering voice of a user through a microphone 110 of the voice terminal 100, steps S13 to S16 of receiving and analyzing the input voice using a language processing module, steps S17 to S19 of transmitting the analyzed voice to a plurality of voice authentication servers 200 and 210 to verify and store each voice, and step S20 of learning the stored voice using an AI processor.

[0035] In steps S10 to S12 of inputting and registering the voice of the user, it is preferable to input and register by designating and selecting a specific user. For example, a specific user such as the user, mother, father, son, daughter, or acquaintance may be designated and selected as the user.

[0036] In addition, in steps S13 to S16 of analyzing the voice using the language processing module, it is more preferable to classify the voice of the user according to pronunciation, speed, respiration, rhythm, and vocal features, determine each emotional state, and store and analyze the voice for each emotional state.

[0037] In addition, as illustrated in FIG. 2, this figure is the control block diagram illustrating the voice verification and restriction method of the voice terminal according to the embodiment of the present invention. The b) voice verification step includes step S21 of mutually comparing the voice input in the step a) with voice stored in at least one server among voices stored in the plurality of voice authentication servers 200 and 210 and verifying the voice, steps S22 to S24 of performing approval and a voice command when the input voice matches the stored voice, and a step of setting restrictions on all or some of functions of the voice terminal and executing a step-by-step action designated by the user when the input voice does not match the stored voice.

[0038] In this case, a specific guidance message according to non-approval may be output, and a setting lock or non-setting operation may be performed.

[0039] In step S21 of mutually comparing and verifying voices stored in the plurality of voice authentication servers 200 and 210, it is preferable to mutually compare voices stored in two different servers 200 and 210, thereby being able to more accurately verify reliability based on whether or not the stored voices match each other.

[0040] In addition, in step S28 of setting function lock of the voice terminal, after initial lock setting for all or some of the functions of the terminal 100, when voice is repeatedly mismatched upon re-entry, the user executes the step-by-step response action designated in advance. In step 1, an authentication message may be transmitted to a user terminal, in step 2, a warning message may be transmitted to a terminal set in advance by the user, and in step 3, a location tracking and emergency notification message may be transmitted to a mobile operator or a police station.

[0041] That is, after the initial lock setting for all or some of the functions of the terminal, when voice is repeatedly mismatched upon re-entry, the step-by-step response action designated in advance by the user is executed. However, the step-by-step action may be different in the order of each action depending on the selection of the user.

[0042] The voice terminal may be applied to various mobile terminals having a mobile or portable form or a stationary form, more specifically, to various mobile terminals such as vehicles, ships, and airplanes in addition to mobile phones, notebooks, tablet computers, computers, headsets, earphones, Bluetooth devices, speakers, and IoT products.

[0043] In addition, one or more languages, such as Korean, English, Japanese, and Chinese, may be selected in the a) voice storage step and the b) voice verification step.

[0044] In addition, FIGS. 3 and 4 are diagrams illustrating examples of use of the voice verification and restriction method of the voice terminal according to an embodiment of the present invention, and FIG. 5 is a control block diagram illustrating a command processing step through a voice input by a specific user when one or more users are preset according to an embodiment of the present invention.

[0045] As illustrated in the figures, in the case where one or more users are preset, when a specific user gives a command through voice input, voice of the user stored in the voice authentication server is checked. When a preset user matches, a name of the user is called (which may be deleted in actual product implementation), and the command is executed.

[0046] In addition, the voice verification and restriction method of the voice terminal is provided and has the following characteristics. A name of the user is called and a command is executed. Alternatively, a command is executed after a procedure of confirming the user, and when the user does not match, a comment about the fact that the user does not match is made, or the operation returns to an initial stage again after a procedure of confirming that the user does not match. When the voice of the user is not set, a command according to the voice of the user is executed without a separate voice authentication procedure.

[0047] On the other hand, when the voice of the user stored in the voice authentication server is checked, and the preset voice of the user does not match, a comment about the fact that the user does not match is made, and the operation returns to the initial stage again.

[0048] When the voice of the user is not set, a command according to the voice of the user may be executed without a separate voice authentication procedure.

[0049] A voice verification and restriction method of a voice terminal according to the present invention configured as described above has an effect of effectively addressing loss or theft of a terminal by setting restrictions for all or some of functions of the terminal and then executing a step-by-step response action designated by a user when voice does not match repeatedly in order to prevent unauthorized use by others and leakage of personal information.

[0050] In addition, there is an effect of accurately and safely recognizing and verifying voice of a user by storing voice of the user in a plurality of authentication servers to mutually compare and verify the voice and by storing user voice for each emotional state using a language processing module.

[0051] Effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the above description.

[0052] The embodiments of the present invention described in this specification and the configurations illustrated in the drawings relate to preferred embodiments of the present invention, and do not encompass all the technical spirit of the present invention. Therefore, it should be understood that various equivalents and modifications may be present to substitute therefor at the time of filing. Accordingly, the present invention is not limited to the above-described embodiments, and various modifications can be implemented by anyone with ordinary skill in the art to which the invention pertains without departing from the gist of the invention as claimed in the claims. Further, such changes are within the scope of the claims of the present invention.
