Abstract

A method for providing a portable phone service by using a natural language speech function is provided to specify functions of the portable phone and to implement the functions rapidly requested by a user by determining a service menu or subordinate menus via a natural language process in case that the user inputs usually used natural language. A method for providing a portable phone service by using a natural language speech function comprises the following several steps. The portable phone checks whether it is located under environment where natural language speech is properly realized(S101). In case that surrounding noise is severe, the portable phone displays a message that a portable phone service via the natural language speech recognition is impossible(S111) and guides the user to input instructions via a keypad(S112,S113). In case that the natural language recognition is possible, the user inputs the natural language speech(S102). The portable terminal checks whether the natural language speech is a proper instruction regarding implementation of a portable phone function(S104). If so, the portable phone checks whether the instruction is for making a call connection(S105). If not so in the step S104, the portable phone performs an exception processing routine(S106). If the instruction is for making a call connection in the step S105 and the user has to input a phone number directly, the portable phone attempts to make a call connection to a terminal with the directly inputted phone number(S110). If the natural language speech includes a name and a phone number of a callee, the portable terminal performs corresponding routines(S108). If the natural language speech includes only a name of the callee, the portable terminal performs corresponding routines(S109).

Description

Cell phone service using natural language speech recognition {CELLULAR PHONE SERVICE METHOD USING NATURAL LANGUAGE SPEECH RECOGNITION}

The present invention relates to a mobile phone service method, and more particularly, to a mobile phone service method for implementing a mobile phone function using a natural language voice recognition function of the mobile phone.

With the recent development of wireless communication technology, mobile phones are now recognized as necessities of life.

In particular, mobile phones are equipped with various functions such as music file playback, alarm, schedule management, Internet access, and games as well as basic functions such as telephone calls.

With the advent of mobile phones having many functions as described above, in order for a user to be familiar with various functions of such mobile phones and to use them properly, it is necessary to facilitate inquiry and selection of mobile phone functions.

Regarding the function of the mobile phone or the display of the service, in the related art, similar functions are grouped into one category to create a higher concept (hereinafter, referred to as a 'service menu'). For example, services such as "Find phone number", "Add phone number", "Edit phone number", "Phone business card", and "My number / information" are registered in the service menu called "Phone book".

Therefore, as a user, for example, when selecting "phone number search", the user could select a higher level "phone book", select a corresponding service, and then, for example, make a call to the phone number.

However, according to the conventional mobile phone service method, there is a problem in that the process of achieving the desired mobile phone function is cumbersome because the service selection always requires starting with the upper concept and selecting the service of the lower concept.

In addition, there is a problem that it takes a lot of time to find if the user does not know which service menu the mobile phone function desired. In particular, the settings of the service menu and its submenus may vary depending on the manufacturer of the mobile phone, so that the user may feel more confused when searching for the mobile phone function.

Accordingly, it is recognized that the user can easily and easily use various functions provided in the mobile phone.

On the other hand, the mobile phone has a product provided to recognize the user's natural language voice according to the type to perform the mobile phone function that the user requests. However, a mobile phone having such a voice recognition function has a higher concept enumerating a plurality of menus step by step from the selection of a service menu to the lowest menu so that the user can finally select a mobile phone function to be selected by a user's alternative method. do.

Therefore, since the selection process is repeated step by step, the implementation of the mobile phone function using natural language voice takes much more time than the case of selecting the mobile phone function through key operation.

SUMMARY OF THE INVENTION An object of the present invention is to provide a mobile phone service method that enables a user to easily and easily find and use a desired function among various mobile phone functions. More specifically, the present invention provides a mobile phone service method for recognizing a user's natural language voice so as to quickly find and implement a mobile phone function desired by the user.

In order to achieve the above object, the present invention provides a plurality of service menus having jurisdiction over different categories regarding the implementation of mobile phone functions, and having a plurality of sub-menus for implementing different mobile phone functions within the same category. Setting up; Recognizing a natural language voice of a user and determining a meaning of the natural language voice through natural language processing of the natural language voice; Determining a service menu corresponding to the semantic meaning of the natural language voice among the plurality of service menus; Determining a submenu when one of a plurality of submenus belonging to the determined service menu corresponds to the sense of the natural language voice; And implementing a mobile phone function specified by the determined service menu and the sub-menu.

The mobile phone service method may further include: requesting an additional input of a child voice for further specification when a plurality of mobile phone functions specified by the determined service menu and sub-menu exist; Recognizing a user's additional natural language voice for the additional specification and determining a meaning of the additional natural language voice through natural language processing of the additional natural language voice; And specifying a mobile phone function related to the meaning of the identified additional natural language voice among the plurality of mobile phone functions.

The mobile phone service method may further include specifying a mobile phone function set as a default among the plurality of mobile phone functions when there is no natural language voice of the user for specifying the mobile phone function for a predetermined time. .

In addition, the mobile phone service method may request confirmation of whether to implement the specified mobile phone function, and if there is no confirmation by the user's natural language voice or key input for a predetermined time, the mobile phone service method may be implemented. Can be.

The mobile phone service method may further include presenting all of the plurality of submenus belonging to the determined service menu when none of the plurality of submenus belonging to the determined service menu corresponds to the sense of the natural language voice. ; The method may further include determining a submenu from the natural language voice by determining a meaning of the natural language voice of the user for determining any one of the presented plurality of submenus through natural language processing.

In addition, the mobile phone service method, it is determined whether or not the environment is possible to recognize the natural language voice, if it is determined that the environment is not possible to recognize the natural language voice, the user is required to input the key and the mobile phone according to the user's key input thereto You can also specify a function.

In this case, the mobile phone service method may determine whether the natural language voice can be recognized, and if it is possible to recognize the natural language voice, collect the keyword command from the natural language voice of the user to specify the mobile phone function.

On the other hand, to achieve the above object, the present invention provides a mobile phone service method comprising the steps of: setting one or more service menus that govern different categories related to the implementation of a mobile phone function; Recognizing a natural language voice of a user and determining a meaning of the natural language voice through natural language processing of the natural language voice; Determining a service menu corresponding to the semantic meaning of the natural language voice among the plurality of service menus; And when there are a plurality of methods for implementing the mobile phone function specified by the determined service menu, when there is no natural language voice of the user regarding the method for implementing the specified mobile phone function for a predetermined time, the method set as default. According to the present invention, there is provided a mobile phone service method comprising the step of implementing the specified mobile phone function.

According to the present invention as described above, even when a user inputs a natural language commonly used in a mobile phone, the mobile phone function associated with them is identified by quickly determining a service menu and one or more sub-menus belonging to it through natural language processing thereof. As a result, the mobile phone functions required by the user can be quickly implemented.

In the mobile phone service method according to an exemplary embodiment of the present invention, as shown in FIG. 1, the mobile phone 1 recognizes a natural language of the user 2 through natural language processing, and performs a mobile phone according to the natural language voice. It is done by implementing the function.

In the implementation process, the mobile phone 1 sends out a comment requesting to confirm a synthetic voice or a more specific natural language voice as a command for recognizing the user's natural language voice and implementing the corresponding mobile phone function. The detailed natural language voice of the corresponding user may be recognized to implement the corresponding mobile phone function. In short, the function implementation of the mobile phone 1 can take the form of talking with the user 2.

A detailed implementation process of the interactive cellular phone function will be described later.

2 is a conceptual diagram exemplarily classifying various functions of the mobile phone 1 by category. As shown in the figure, the user 2 wants to achieve through the mobile phone 1 is largely 'call', 'send message', 'schedule management', 'wake-up / alarm management', 'MP3', ' Received message / telephone management ”.

Each service menu 11 again has one or more submenus 12.

For example, for 'Call phone', '1. Call by phone number ',' 2. Dial by type of incoming number ',' 3. Call without type of receiving number '.

The generation and division of the category of the service menu 11 can be set according to a user's request, and which of the service menus 11 refers to the mobile phone 1 automatically recognizing the user's natural language voice. In order to match, it is desirable to link synonyms, synonyms, and the like of the service menu 11 (also referred to as 'table control') together.

For example, a natural language voice referring to a message in 'send a message' recognizes a user's pronunciation as the same as the 'message', or a natural language voice referring to a 'schedule' in a 'schedule management'. The pronunciation of 'schedule' can be recognized together with the same as the 'schedule'.

As described above, various functions of the mobile phone are divided into a plurality of categories, and the service menu 11 and the sub-menu 12 are matched for each category, so as to be described later. After distinguishing the service menu and the sub-menu to recognize, as described later, to implement the mobile phone function associated with the sub-menu.

Service categories and their subdivisions as shown in FIG. 2 for cellular phone functions may be set or modified by the user to allow the user to design them to their liking.

3 is a conceptual diagram illustrating an execution process of a mobile phone service method according to an embodiment of the present invention.

The user 2 inputs natural language voice related to the mobile phone function to be implemented. The natural language voice takes the form of a command in natural language, for example, "Call Hong Gil Dong." By allowing natural language voice to be input as it is, it is possible to use everyday language as a command of a mobile phone, so that it is not only convenient to use, but also allows the user to feel like talking with a mobile phone. have.

When the natural language voice of the user 2 is input, the cellular phone 1 first performs automatic speech recognition 21. This automatic recognition may simply take the form of keyword spotting to check whether the user's 'service menu' and 'submenu' are included in the natural language voice of the user, or as a more advanced form, By recognizing the user's natural language voice as a whole sentence, a method of text understanding may be taken.

For example, according to the keyword spotting, the keywords 'hong gil dong' and 'telephone' are recognized from the user's natural language voice of "call me hong gil dong". In response to the submenu 12 called 'dial without type of receiving number' in the service menu 11 called 'Hong-Gil-Dong', a mobile phone function called dialing can be implemented.

Meanwhile, according to the text understanding method of recognizing a natural language voice as a whole sentence, the user's natural language voice of "Call Hong Gil Dong" is literally texted and analyzed and analyzed by a parser. It grasps the intention of the user and makes a call to Hong Gil-dong as the user requests.

After the automatic recognition of the natural language voice input from the user 2, the meaning of the natural language voice is recognized (22).

If automatic recognition is performed by the keyword spotting, the semantic grasp spotting keywords of 'Hong Gil-dong' and 'telephone' to find Hong-Gil-Dong from the number stored in the mobile phone. It can be understood that.

Meanwhile, according to a text understanding method of recognizing the natural language voice as a whole sentence, it is possible to grasp the overall user's intention by analyzing the meaning of the textized sentence "Call Hong Gil Dong." To understand the meaning of the command.

When the meaning is determined from the user's natural language voice, a process of matching a service menu and a submenu corresponding thereto is performed (23). Accordingly, the service menu 11 and the submenu 12 associated with the keyword spotting or the natural language voice are determined based on the meaning of the natural language voice determined according to the method of recognizing the natural language voice as a whole sentence.

When the service menu 11 and the submenu 12 are determined, it is determined whether to implement a mobile phone function related thereto (24). That is, according to the above example, a text or synthesized voice asking whether to actually call Hong Gil-dong, such as "Do you call Hong Gil-dong?" On the other hand, if there is a positive answer from the user 2, such as "yes", "yes", "yes", etc., to implement the corresponding mobile phone function (dial Hong Gil-dong) (25).

If there are several numbers stored under the name Hong Gil-dong or two or more people named Hong Gil-dong, more specific designation is required. In this case, the user is asked to send a comment requesting additional natural language voice as a synthetic voice. Induces additional natural language speech input (24). In this regard, a new cycle 21 to 24 takes place by the user re-entering additional natural language voices for the requested matter.

The construction of process scenarios (flows) in service menus and submenus, automatic recognition of natural language speech, grammar and language characteristics recognition for semantics, matching with service menus and submenus, and creation of synthesized voices It is made based on the base 3.

Hereinafter, a process in which the mobile phone service method is actually implemented on the mobile phone through the above process will be described in detail.

4A to 4C are flowcharts illustrating a mobile phone service process according to the 'call' service menu 11 of FIG. 2.

First, the mobile phone 1 determines whether the environment is suitable for the natural language voice recognition (S101). That is, when the ambient noise is severe, for example, when the ambient noise level exceeds a predetermined level, a display indicating that the mobile phone service is not possible through natural language voice recognition is displayed (S111) through the keypad. Induces a command input (S112-> S113).

In response to this, the user may input a command using a keypad or move to a quiet place to input natural language voice.

If the user inputs a natural language speech (Speech) in the natural language (S102) under the environment capable of recognizing the natural language voice (S102), the mobile phone 1 performs natural language processing on this to grasp the meaning of the input natural language voice. The natural language processing is performed by keyword spotting described above, a method of recognizing a natural language voice as a whole sentence, and the like.

Thereafter, after determining whether the natural language voice is a correct command for implementing a mobile phone function (S104), if it is a correct command, it is determined whether the command is related to the 'call' service menu 11 (S105). If the correct instruction is not executed, an exception handling routine is performed (S106). An exception handling routine will be described later.

If it is determined in step S105 that the command is related to the 'call', and if the phone number is directly input command form (S107) and performs a call to the corresponding number (S110).

On the other hand, if the user's natural language voice includes the recipient (Hong Gil-dong) and the type of receiving number (mobile phone), such as "Call me to Hong Gil-dong's mobile phone", go to step S108 and go to <1-1> Routine ( 4b).

On the other hand, if there is only a recipient (Hong Gil-dong) and does not include the type of receiving number (mobile phone, home phone, or work phone), such as "Call Hong Gil-dong", go to step S109 and go to <1-2> routine. (FIG. 4C).

Therefore, as described above, when the user's natural language voice corresponds to 'calling', which is a service menu, and also corresponds to any one of the submenus S107 to S109, the corresponding service menu and its submenu are requested by the user. The mobile phone function (here, dialing) specified by the determined service menu and submenu is automatically implemented.

4B is a flowchart showing the <1-1> routine determined by the step S108 in more detail. When the recipient (Hong Gil-dong) and the receiving number type (mobile phone) are determined as sub menus such as "Call me to Hong Gil-dong's mobile phone" from the user's natural language voice, first check whether there are multiple sub-menus of 'Hong Gil-dong' (S120). In other words, it checks by checking whether two or more persons are stored with the same name. As a result of the check, if there is only one 'Hong Gil-dong' (S121), the user obtains a confirmation such as "Choose to call Hong Gil-Dong" by synthesized voice or text display (S122). On the other hand, if the user has a positive natural language voice such as "yes", "yes", "yes", and performs the call to the corresponding number (S123). In addition, when no natural language voice is input from the user, that is, in the case of silence, the voice is recognized as a positive answer, and the corresponding function is performed after a predetermined time elapses (S123).

As a result, the user can simply call Hong Gil-dong's mobile phone by simply saying a natural language voice, "Call me to Hong Gil-dong's mobile phone."

On the other hand, as a result of the check, if there are two or more people stored as 'Hong Gil-dong', the phone numbers of the searched 'Hong Gil-dong' are listed and displayed in a list (S124). In this case, there are a plurality of mobile phone functions specified by the service menu 'Call phone' and its submenus 'Hong Gil-dong' and 'Mobile phone', wherein the mobile phone 1 additionally has a user call. To select the intended recipient (S125). The selection of the recipient may be by a method of calling the number of the list as a natural language voice (ie, additional input of the natural language voice) or by pressing a corresponding number through a keypad. If the receiver is selected, a confirmation is made whether or not to implement a call function to the receiver (S126). Even in this case, when the user answers affirmatively or keeps silence for a predetermined time, the caller function is executed, and when the user answers a negative answer, the user returns to the original main mode (S128-). > <1>).

In addition, when the user does not select a receiver from the list for a predetermined time in step S125, it is assumed that the default value, that is, in this embodiment, 1 is selected as the receiver (S127), and then steps S126, S128, and S123 are performed. Make a call to the intended recipient.

4C is a flowchart showing in more detail the routine <1-2> determined by step S109. In other words, the user's call function specified by 'Hong Gil Dong' submenu of 'Call Phone' such as 'Call Hong Gil Dong' is called 'Call Hong Gil Dong's Mobile Phone', 'Call Hong Gil Dong's Home', This is a routine when there are a plurality of things such as 'calling Hong Gil-dong's office'. Of course, at this time, there may be a plurality of search results of 'Hong Gil-dong'.

Therefore, when there are several results confirmed through the recognition of the user's natural language voice, the mobile phone 1 first displays the results in a list (S130-> S136) and allows the user to select among them (S137). . The user implements a specific dialing function by additionally inputting a corresponding number (receiver) and a received number type (mobile phone, home, office) as natural language voice (S138) (S141-> S142-> S135).

On the other hand, even in this case, when there is no additional specification of the user for a plurality of confirmation results, a call is made to the default number of the first receiver S140 (that is, the first telephone type, S139) which is the default.

5A through 5C are flowcharts illustrating a mobile phone service process according to the 'send message' service menu 11 of FIG. 2.

First, referring to FIG. 5A, it is determined whether the service process of the service menu 11 of 'send a message' is also a command related to the 'send message' service menu 11 through the same steps as the service process of the 'call'. It is determined (S201).

If it is determined in step S201 that the command is related to the 'send message, first enter the message content, and then specify the recipient (S202-> <2-1>) whether or not to specify the recipient first and then enter the content It is determined whether to select (S203-> <2-2>).

The selection of this method is made based on grasping the meaning of the user's natural language voice.

That is, for example, if the user simply says "send a message", since there is no receiver in the natural language voice, the method of inputting the content first is determined (S202-> <2-1>), and the user sends a message to "Hong Gil-dong." ", Since the receiver is specified as 'Hong Gil-dong', a method of sending a message to the recipient specified as 'Hong Gil-dong' (ie, S203-> <2-2>) is determined.

The service process of <2-1> relating to the method of first inputting content starts with outputting a message creation screen, as shown in FIG. 5B (S211). Accordingly, after the user inputs a message (S212), the receiver is specified in a natural language voice (S213) or the receiver number is directly input (S221).

The voice input method of the receiver proceeds similarly to the method described in the telephone call of Figs. 4B and 4C. That is, when the user 2 inputs the recipient's name, number, etc. in natural language voice, the mobile phone 1 searches for the corresponding name, number, etc. (S213). After obtaining confirmation (S215), a message is transmitted (S219). At this time, if the user 2 does not confirm in natural language voice for a predetermined time, the message transmission function is automatically performed.

If there are two or more corresponding recipients, the result is output (S217) and the user 2 is selected (S218). In this case, if the user 2 does not make a selection for a predetermined time, the mobile phone 1 automatically determines that a default value (recipient 1 in FIG. 5B) is selected and performs a message transmission function.

The service process of <2-1> relating to the method of first inputting content starts with outputting a message creation screen, as shown in FIG. 5B (S211). Accordingly, after the user inputs a message (S212), the recipient is inputted in natural language voice (S213) or the recipient is specified in a manner of directly inputting a received number (S221).

The service process related to the method for sending a message to a specified recipient proceeds in the reverse of the case of FIG. 5B, as shown in FIG. 5C. That is, the receiver specified by the user's natural language voice is searched (S231), and if the corresponding receiver is searched by one person, the result is output (S232-> S233), and the confirmation is obtained (S234). S237). Subsequently, the message creation screen is output (S238), the user inputs a message, and then a message is transmitted (S239).

If there are two or more recipients specified from the user's natural language voice, the result is output (S235), the user 2 is selected (S236), the recipient is designated (S237), and the message composition screen is output ( S238) The user inputs a message to perform a message transmission (S239).

6 to 8 are flowcharts illustrating a mobile phone service process according to the 'schedule management', 'wake-up call / alarm management' and 'incoming message / telephone management' service menus 11 of FIG. 2, respectively.

Referring to FIG. 6, when the user makes a natural language voice, for example, "I want to register a schedule," the mobile phone service process routine (<3-1>) regarding the schedule registration proceeds directly from step S301 to step S302. The contents are omitted).

In the same way, when the user requests the schedule check, the process proceeds in the order of S301-> S303 to execute the service process routine (<3-2>, details are omitted) regarding the schedule check, and the schedule can be deleted in the order of S301-> S304. The schedule editing is performed in the order of S301-> S305 to execute the corresponding service process routines (<3-3> or <3-4>, details are omitted), respectively.

Referring to FIG. 7, when the user speaks a natural language voice, for example, "Let's check the alarm", the mobile phone service process routine (<4-2>) regarding the alarm check is proceeded directly to step S401 to step S403. Will be omitted).

In the same way, when the user requests registration of an alarm or a wake-up call, the procedure proceeds from S401 to S402 to execute a service process routine (<4-1>, details are omitted) relating to the alarm or wake-up call, and the alarm or wake-up call. Deletion proceeds in the order of S401-> S404 to execute the corresponding service process routine (<4-3>, details are omitted).

FIG. 8 is an execution process of the “received message / telephone management” service menu 11, and when a natural language voice is input from the user 2, for example, “let's check the received message” or “delete the received message”. In step S501-> S502, the service process routine (<5-1>, details are omitted) is executed immediately.

In addition, in the case of receiving a natural language voice such as, for example, “Are you not calling?” Or “Let me store the received call” from the user 2, the process proceeds directly to S501-> S503, and the corresponding service process routine ( <5-2>, details are omitted).

9 is a flowchart illustrating a mobile phone service process according to the 'MP3' service menu 11 of FIG. 2.

For example, when the user receives a natural language voice of "Please turn on the song Yong-pil song" from the user, after confirming that the MP3-related command in step S601, and outputs the song list of "Joe-pil" through the keyword search (S602) (S603). Thereafter, when the user selects from the list (S604), the selected song is played (S605). If the user does not select from the list for a predetermined time, songs are played by default, for example, in list order (S605).

On the other hand, when the user simply does not have a specific submenu (eg, 'Joy Phil'), such as "Play Music," there are various submenus of music. In this case, all lists can be displayed. When no more user natural language voice is input, music can be played in the order of the list.

Therefore, according to the mobile phone service process as shown in FIG. 9, the user can automatically play the MP3 music by simply making a natural language voice of "music".

FIG. 10 is a process routine related to 'exception processing' shown in each service process of FIGS. 4A (S106), 5A, and 6 to 9, and the mobile phone 1 recognizes that the user's natural language voice is not a correct command. The processing method in the case of judgment is shown.

First, when it is determined that the user's natural language voice is different from the upper menu 'service menu', the user is induced to branch to another 'service menu' (S701), and accordingly, the optimal 'service' recognized through the user's natural language voice. Menu '(S702-> S703-> S704-> S706). If, in the middle, the user wants to return to the originally selected 'service menu', the user returns to the main screen of the corresponding 'service menu' after the confirmation process (S704) (S705).

Even in this case, when there are a plurality of optimal 'service menus' recognized through the user's natural language voice, the result is output (S707) and the user is selected (S708) to branch to the selected 'service menu' (S708). S706). Of course, if there is no user selection for a predetermined time, it is regarded as being selected as a default value (service number 1 in the drawing) (S709) and branches to the corresponding service menu (S706).

On the other hand, if the natural language voice related to the user's 'service menu' is input to a degree that is insufficient for the mobile phone 1 to recognize, the cause is output (S710-> S711), and in this regard, the user can set the voice recognition function of the mobile phone. Allows the user to check, change settings, and provide help (S712-> S714). In this case, if there is no user input, the screen returns to the main screen of the corresponding service menu (S713).

The above-described mobile phone service method is only one embodiment for describing the present invention and should not be understood as being limited to the technical scope and the scope of the present invention, and the technical scope and scope of the present invention will be described later.
