In addition, a part of the cellular phone 1 is provided with a TV signal processing unit 9 capable of tuning a TV broadcast signal to operate under the function control of the microcomputer 4, and at one end of the microcomputer 4 The ROM 10 and the RAM 11 for storing the data are connected, and the handset 12 is connected to the data signal processor 5. In addition, an operation switch 14 for controlling the operation of the cellular phone on / off is installed at one end of the cellular phone folder 13 junction part or flip part.

Here, the displays 6A-6D are plural, for example, four or more on the inner side of the folder 13 of the cellular phone with the key panel portion removed and the outside of the inner body 16 as shown in FIG. It is installed as LCD screen and also used as touch screen function.

Then, at one end of the microcomputer 4, if the user touches the displayed menu screen on the screens of the displays 6A-D by hand, the touch screen detects the signal and processes the signal and inputs it to the microcomputer 4. The detection sensor unit 17 is connected.

Next, the operation and effects of the embodiment of the present invention having the above configuration will be described.

According to one embodiment of the present invention, when the user opens the folder 13 of the cellular phone 1 of the present invention to execute a desired function as shown in FIG. 3, an operation switch installed at the junction of the folder 13 is shown. The microcomputer 4 recognizes this and executes the functions of the system because the operation 14 is activated.

That is, the microcomputer 4 of the cellular phone initializes the system when the operation switch 14 is operated as shown in FIG. 4, and then sets the menu command on the initial screen of each of the displays 6A-D of the cellular phone. For example, it displays a screen with logos or graphics. Then, after the initialization step (S1) and proceeds to the phone mode determination step (S2) and the current user has set the phone mode by voice, proceeds to the phone mode display step (S3) to call any one of the plurality of display screens It displays a logo indicating the mode setting and prompts you to set a phone number. After the telephone mode display step (S3), the process proceeds to the telephone number setting determination step (S4) to determine whether the current telephone number is set to voice from the user.

On the other hand, if the telephone number is set by the user as a result of the determination in the telephone number setting determination step (S4), it proceeds to the telephone function execution step (S5) to execute the normal telephone call function.

However, if the voice signal for setting the phone number is not input within a predetermined time as a result of the determination in the phone number setting determination step (S4), the process proceeds to the phonebook mode determination step (S6) and the phone is stored in the cellular phone. Determine whether to search the phone book. Therefore, if it is determined during the telephone book mode determination step S6 that the voice command signal for requesting the telephone book search is not input from the user within a predetermined time, the process returns to the initialization step S1 and repeats the loop.

However, if the voice command signal for requesting the phone book search is input from the user as a result of the judgment during the phone book mode determination step (S6), the process proceeds to the phone book menu execution step (S7) and the phone book according to the voice command signal. After executing the search, the process proceeds to the telephone function execution step (S5) and repeats the loop.

That is, when the user opens the folder to use the cellular phone of the present invention, the operation switch 14 installed in the folder junction is activated, and the microcomputer 4 which recognizes this operates the cellular phone. At this time, the microcomputer 4 displays, for example, a logo or a graphic screen on the plurality of displays 6A-6D formed through the data signal processing unit 5 according to the program stored in the ROM 10, and displays the display (6A-D) screen. One of the screens, for example, displays a text signal requesting to set a desired menu on display 1 (6A) or display (6D). Then, when the user wants to speak to the cellular phone by voice, for example, "telephone", the microphone 7 installed in a certain portion of the cellular phone 1 detects this and sends it to the voice recognition processing IC 8. Enter it. The voice recognition processing IC 8 analyzes the input voice signal of the user according to the built-in program, converts it into a digital voice data signal corresponding to the voice, and inputs it to the microcomputer 4. Thus, the microcomputer 4 judges the digital voice data signal input from the voice recognition processing IC 8 to recognize that the "telephone" menu is currently set and executes the phone menu function according to the program embedded in the ROM 10. Let's do it. Then, the microcomputer 4 requests to input a phone number from the user by voice on the display 1 (6A) screen through the data signal processor 5 according to the telephone menu function.

At this time, if the user inputs a phone number by voice, for example, when the phone number is "123-4567", the user voices each of these numbers by voice and then calls "call". 7) is input to the voice recognition processing IC (8). Then, the voice recognition processing IC 8 analyzes the voice signal corresponding to the input user's telephone number according to the built-in program, converts the voice signal into a digital voice data signal corresponding to the voice, and inputs it to the microcomputer 4. Therefore, the microcomputer 4 recognizes the digital voice data signal corresponding to the telephone number input from the voice recognition processing IC 8 and executes the telephone function according to the set telephone number. For example, the microcomputer 4 inputs a dialing signal according to a telephone number to the digital signal processing unit 3, and accordingly, the digital signal processing unit 3 digitally processes the input dialing signal and performs the wireless signal processing unit 2. Enter Then, the radio signal processor 2 loads the input dialing signal on the RF signal and emits it to the outside through the antenna 15. Then, a call is made through the handset 12 through a base station system (not shown) located in a cell to establish a call with the other party.

However, if the microcomputer 4 displays a screen requesting the user to input a phone number by voice on the display 1 (6A) screen, a signal for setting the phone number by voice is not input even after a predetermined time elapses. If not, a message is displayed on the screen of display 1 (6A) asking if you want to execute the phonebook search function. At this time, if the user utters "click" or "selection" by voice, the microcomputer 4 recognizes it through the voice recognition processing IC 8 and stores the phonebook previously stored in the ROM 10 or RAM 11 in the order in which they are stored. Display 1 (6A) is displayed.

At this time, when the user clicks or selects when the desired number of the phone numbers displayed on the display 1 (6A) is displayed on the screen, the microcomputer 4 generates the voice recognition processing IC 8. It recognizes through and executes call function with the selected phone number. However, the microcomputer 4 displays the initial screen on the display 1 (6A) or the display 4 (6D) when no telephone number is input by voice from the user even after a certain time elapses.

Here, the phone numbers stored in the phone book menu are data that the user has selected in the phone book menu function and stored in the RAM 11 by voice in advance.

On the other hand, if it is determined during the telephone mode determination step (S2) that the current user has not set the telephone mode by voice, the method proceeds to the additional menu determination step (S8) and displays additional menus sequentially on the display screen and the audio output signal. It is determined whether the submenu is selected by voice in time. As a result of the determination in the additional menu determination step S8, if the additional menu is not selected by voice within a predetermined time, the initial screen is displayed in the initializing step S1.

However, as a result of the determination in the additional menu determination step (S8), if the additional menu is sequentially displayed on the display screen within a predetermined time, for example, a voice message menu, an electronic notebook menu, a phone book menu, a bell / vibration / size menu, and personal information. If a voice signal for selecting any one of a menu, an Internet menu, a TV menu, and a game menu is input, the display proceeds to the sub submenu displaying step S9. For example, in the case of an electronic notebook menu, a submenu Display submenus such as schedule management, to-do management, electronic calculator and alarm. After the sub submenu display step S9, the process proceeds to the submenu setting determination step S10 to determine whether the user has selected one of the current submenus displayed as a voice within a predetermined time. Therefore, if it is determined during the sub-menu setting determination step (S10) that the voice signal is not input from the user within a predetermined time, the process returns to the previous step (S9) and repeats the loop.

However, if the voice signal for selecting the submenu is input from the user as a result of the determination during the submenu setting determination step (S10), the process proceeds to the setting menu execution step (S11) to execute the set submenu.

That is, when the user speaks "Additional Menu" while the initial screen is displayed on the displays 6A-6C, the microcomputer 4 recognizes this via the voice recognition IC 8 and then adds an additional menu, for example, a voice message. Menus, organizer menus, phone book menus, bell / vibration / size menus, personal information menus, Internet menus, TV menus, and game menus are displayed in sequence on display 1 (6A) or display 4 (6D). It is also output as a voice through the flower bed 12.

Here, since the type of the additional menu can be variously converted and added according to the program provider, the additional menu illustrated in the present invention is just one example of such a menu. In the above description, the menu screen is described as being displayed only on the display 1 (6A) or the display 4 (6D), but the present invention is not limited thereto and may be variously displayed on the plurality of displays 6A-D according to the designer. have.

On the other hand, if the user utters a voice of "Internet" within a certain period of time on the additional menu screen displayed on the display 1 phase 6A, the microcomputer 4 recognizes it through the voice recognition processing IC 8 to execute the Internet menu. In this case, the microcomputer 4 displays the Internet web browser screen on the display 2 (6B) screen. When the user sets a domain or IP for setting an Internet site by voice within a predetermined time, the microcomputer 4 recognizes it through the voice recognition processing IC 8 and externally recognizes the corresponding Internet site through the wireless signal processing unit 2. Connect to the internet network, display on the display 2 (6B) and execute the corresponding function.

If the user makes a voice with "TV" to set the TV menu in the submenu, the microcomputer recognizes it as the voice recognition processing IC 8 and displays the TV submenu on the display 3 (6C) screen. For example, the TV submenu screen displays screens related to other TV controls such as channel setting and volume control. At this time, when the user speaks the TV channel by voice, the microcomputer 4 recognizes it through the voice recognition processing IC 8 and turns on the TV signal processing unit 9. Then, the TV signal processing section 9 tunes the set broadcast channel and inputs the tuned signal to the data signal processing section 5. Accordingly, the data signal processor 5 separates the input TV broadcast signal into video and audio signals, displays the video signals on the display 3 (8C), and outputs the audio signals through the handset 12. FIG. Therefore, the user will watch the TV broadcast displayed on the display 3 (6C).

Here, when the user wants to switch to another menu while executing the additional menu function, the user only needs to sound a corresponding command signal by voice. For example, if the user wants to make a phone call while executing the TV menu, when the user speaks "telephone", the microcomputer 4 recognizes it through the voice recognition processing IC 8, thereby switching to the phone mode and making a phone call.

According to the present invention, the additional menus may be separately selected on the displays 6A-D, respectively.

In addition, when closing the folder 13 of the cellular phone of the present invention, the operation switch 14 is turned off and accordingly the microcomputer 4 recognizes the basic function of the cellular phone, for example, the other functions except the call waiting function off Done. Therefore, when a communication signal is input from another communication system, the microcomputer 4 notifies this to the outside through the bell alarm unit (not shown) as usual.

Meanwhile, another embodiment of the present invention has a touch screen function in addition to the voice processing function. In other words, the user sets the desired menu by hand on the menu screen displayed on the display 6A-D instead of setting the menu by voice, and the touch screen detection sensor unit 17 detects this. The detected data is then input to the microcomputer 4 as a digital signal. Then, the microcomputer 4 determines the detection data input from the touch screen detection sensor unit 17 to recognize the menu set by the user on the current display 6A-6D, and converts the corresponding menu into the above-mentioned voice processing function. The same process is followed.

As described above, the present invention eliminates the key panel portion of the cellular phone and incorporates a voice recognition processing block so that all control commands are processed as voice signals, thereby requiring the use of a hand to use an additional function of a telephone or other cellular phone. Therefore, it is possible to improve the convenience of use accordingly, as well as to control all the functions of the cellular phone by voice accordingly has the effect of significantly improving the functionality of the cellular phone.
