5 (b), when the user 20 of the other mobile terminal 200 reads the voice feature information extraction statement, the voice of the user 20 of the other mobile terminal 200 reads the above- And is received by the mobile terminal 100 through the wireless communication unit 110 as a signal. 4, the control unit 180 may update the contact information through the voice feature information of the user of the other mobile terminal 200. [

Next, a method of outputting a notification phrase as a voice by using the voice feature information stored in the mobile terminal 100 will be described.

FIG. 6 is a diagram illustrating a method in which a mobile terminal 100 according to an exemplary embodiment of the present invention outputs sound using voice feature information. Referring to FIG. As shown in FIGS. 6 (a) and 6 (b), the mobile terminal 100 may receive a call of at least one other mobile terminal 200.

For example, if the identification information of the other mobile terminal 200 to which the call originated is 010-1234-4321 and the " John Park " in which 010-1234-4321 stored in the contact information of the mobile terminal 100 is stored in the telephone number exists , The mobile terminal 100 can notify the user 10 that the telephone is received from " John Park ".

The control unit 180 can display the identification information 600 of the other mobile terminal 200 and the user 20 of the other mobile terminal 200 that has issued a call to the display unit 151. [ Further, the control unit 180 can display on the display unit 151 a phrase 602 indicating that the telephone call is received. The control unit 180 may further display an object connecting a call with another mobile terminal 200.

At this time, if the contact information matching the identification information of the other mobile terminal 200 is stored in the memory unit 160, the control unit 180 can output the notification text to the ringing tone through the sound output module 152. Here, the ringing tone may be a ring tone output to the sound output module 152 when a call is received.

The control unit 180 can output the previously stored notification text using the voice feature information stored in the contact information corresponding to the identification information of the other mobile terminal 200 in which the call is received.

For example, as shown in FIG. 6 (a), the control unit 180 may apply the voice feature information of " John Park " to the notification text and output it through the sound output module 152 as the voice 606. [

6 (b), if the identification information of the other mobile terminal 200 that has originated the call is 010-4321-1234, the control unit 180 determines that "Sophia Kim Quot; can be applied to the notification phrase and output through the sound output module 152 as the voice 608. [

Next, the functions that can be performed using the voice feature information of the user 10 of the mobile terminal 100 will be described with reference to Figs. 7 and 8. Fig. The mobile terminal 100 may be configured to restrict the access of the other user 10 to the information in the SIM card provided in the mobile terminal 100, the information stored in the memory unit 160, and the mobile terminal 100 itself .

Hereinafter, a file and a lock screen stored in the memory unit 160 whose access is restricted using the voice feature information will be described.

FIG. 7 is a view illustrating a method in which the mobile terminal 100 according to an exemplary embodiment of the present invention displays information restricted in access through voice feature information. FIG. 100) releases the lock screen through the voice feature information.

As shown in FIG. 7 (a), the control unit 180 may display an execution screen 700 of an application program for displaying at least one file stored in the memory unit 160. The control unit 180 may display the object 702 corresponding to at least one file. At this time, the file 704 having the lock function set by the voice feature information of the user 10 may exist in the memory unit 160. Then, the controller 180 may display an indicator 706 indicating that the file is a locked file in an object corresponding to the file in which the lock is set.

Next, when the indicator receives an input touching the displayed object, the controller 180 may display an alert window 708 indicating that the file is a locked file, as shown in FIG. 7 (b) .

Then, as shown in Fig. 7 (c), the user 10 can input the unlocking voice to the mobile terminal 100. [ In one example, the user 10 can input the unlock statement 710 to the microphone 122 by voice.

Then, the control unit 180 can extract the voice feature information from the received unlocked voice. If the extracted voice feature information matches the voice feature information that sets the lock function to the file, the control unit 180 displays the file as shown in FIG. 7 (d) and displays an indicator 712) can be displayed.

8 (a) is a view showing a lock screen 800 of the mobile terminal 100. As shown in FIG. When the control unit 180 receives the input touching the unlock object 802 displayed on the lock screen, the control unit 180 can activate the microphone 122 and receive the unlock statement with the voice of the user 10 speaking.

As shown in Fig. 8 (b), the user 10 can input an unlocking voice to the mobile terminal 100. [ In one example, the user 10 may input the unlock statement 804 to the microphone 122 by voice.

Then, the control unit 180 can extract the voice feature information from the received unlocked voice. If the extracted voice feature information matches the voice feature information set on the lock screen, the control unit 180 displays the home screen 806 as shown in FIG. 8 (c), and displays an indicator 808 ) Can be displayed.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
