Description:
[0001]    The present disclosure relates to the subject matter contained in Japanese Patent Application No. 2002-143564 filed on May 17, 2002, which is incorporated herein by reference in its entirety.  
         BACKGROUND OF THE INVENTION  
         [0002]    1. Field of the Invention  
           [0003]    The invention relates to a navigation apparatus and, more particularly, a navigation apparatus to which a communication device can be connected.  
           [0004]    2. Description of the Related Art  
           [0005]    In the navigation apparatus according to the related art, there are a system to which a communication device such as a mobile phone can be connected to execute communication (including speech) with the outside, and a system which has a hand-free communication function to execute speech during running safely and comfortably.  
           [0006]    In the navigation apparatus to which such a communication device is connected, when the navigation apparatus detects an incoming call or an outgoing call of the mobile phone and then enters into a call mode, the speech of the other person in communication is output from a loudspeaker connected to the navigation apparatus and also the speech picked up by a microphone connected to the navigation apparatus is transmitted via the communication device, so that user can speak with a person who issues/receives the call.  
           [0007]    In such navigation apparatus in the related art, the speech while driving can be executed safely and comfortably by the hand-free communication function, etc. However, such systems do not deal with a case where user wishes to take notes of the content of the speech. Therefore, in order to take notes during speaking, a writing paper, a writing tool, etc. must be taken out. But it is difficult for a driver to prepare them while driving, and such motion of the driver leads to careless forward looking and is undesirable for safety.  
           [0008]    Also, it is troublesome even in the stopping state to take notes by taking out the writing paper, the writing tool, etc. every time while speaking. In addition, it is impossible to take notes at once unless the writing tool, etc. are prepared previously. Thus, there is such a problem that such navigation apparatus is inconvenient.  
           [0009]    Also, in some cases, a driver talks while looking at map information displayed on a screen according to situations. Thus, in such states, the driver would like to take notes of information such as a location of a destination, surrounding buildings, where to make contact, etc., which are heard from the other person in communication. In this case, there is such a problem that the driver cannot easily take notes of the information while looking at the map.  
           [0010]    In addition, in the navigation apparatus according to the related art, such a system has not been provided that speech contents, memo contents, etc. can be automatically registered in a database such as an address book and a phone book. Thus, user must input necessary registration contents separately once again. Hence, there is such a problem that an operation becomes cumbersome and troublesome.

Then, when the “OK” button is touch-input, the contents of the database are updated automatically according to the setting after the change. Then, the display screen  18   a  is switched from the split display screen consisting of the memo screen  32  and the navigation screen  33  to one display screen consisting of the navigation screen after the updating process of the database.  
         [0089]    Also, the memo information stored in the memory  23  can be read later. When a “memo information” button provided in the “menu” screen shown in FIG. 7 is touch-input, the screen is shifted to a “memo information list display” screen shown in FIG. 8.  
         [0090]    In the “memo information list display” screen shown in FIG. 8, communication date, communicated person (if the other person in communication is identified), and the memo that is subjected to the character recognition are displayed. The memo information can be displayed in order of the data by operating a scroll key  34 . Also, function switches such as “cancel”, etc. are provided at the bottom of the screen. For example, the unnecessary memo can be erased easily by designating the memo information, which are to be cancelled, by the touch operation and then touch-inputting the “cancel” button.  
         [0091]    Also, the information of the database stored in the memory  23  can be corrected later. If a “database correction” button provided on the “menu” screen shown in FIG. 7 is touch-input, the screen is shifted to a “correcting-database selection” screen shown in FIG. 9.  
         [0092]    In the “correcting-database selection” screen shown in FIG. 9, a list of the databases stored in the memory  23  is displayed and the database containing information to be corrected can be selected. Then, a button of the database containing the information to be corrected (in this case, “phone book database”) is touch-input, the screen is shifted to a “phone book database correction” screen shown in FIG. 10.  
         [0093]    In the “phone book database correction” screen shown in FIG. 10, a screen on which the name of the person containing the information to be corrected is selected is displayed. When the name of the person containing the information to be corrected is displayed and then a name button that is being displayed (in this case, “Yamashita . . .” button) is touch-input, the screen is shifted to a “correcting item selection” screen shown in FIG. 11.  
         [0094]    In the “correcting item selection” screen shown in FIG. 11, a list of the set items of the database is displayed, and the set item containing the information to be corrected can be selected. Then, a button of the set item containing the information to be corrected (in this case, “phone number” button) is touch-input, the screen is shifted to a “item correction” screen shown in FIG. 12.  
         [0095]    In the “item correction” screen shown in FIG. 12, the registered information can be corrected. In this case, the phone number can be corrected into the correct phone number by touch-inputting the numeral button. If an “end” button is touch-input after the correction, the phone number is corrected to the corrected content. Then, the screen returns to the menu screen shown in FIG. 7.  
         [0096]    Next, processing operations of the memo function executed by the navi control portion  10  in the navigation apparatus according to the embodiment (1) will be explained with reference to a flowchart shown in FIG. 13 hereunder.  
         [0097]    First, in step S 1 , it is decided whether or not the “outgoing call” or the “incoming call” of the communication portion  19  is detected. If it is concluded that the “outgoing call” or the “incoming call” of the communication portion  19  is detected, the process goes to step S 2 . In contrast, if it is concluded that the “outgoing call” or the “incoming call” of the communication portion  19  is not detected, the process is ended.  
         [0098]    In step S 2 , the display indicating that the outgoing call or incoming call is detected as shown in FIG. 2 is executed. Then, the process goes to step S 3 .  
         [0099]    In step S 3 , it is decided whether or not the navigation apparatus has entered into the call mode, i.e., the system is in a call mode. If it is concluded that the system has entered into the call mode, the process goes to step S 4 . In contrast, in step S 3 , when it is concluded that the system has not entered into the call mode, the process is ended.

         [0105]    In contrast, in step S 10 , if it is concluded that the “OK” button is not touch-input, the process goes to step S 20 . In step S 20 , it is decided whether or not a “correction” button is touch-input. If it is concluded that the “correction” button is touch-input, the process goes to step S 21 . In step S 21 , the recognized character correcting process, i.e., the process of correcting the recognized characters is executed. Aster the correcting process, the process goes back to step S 10 . In contrast, in step S 20 , if it is concluded that the “correction” button is not touch-input, the process goes back to step S 10 .  
         [0106]    In step S 11 , the process of storing the communication date, the other person in communication, and the recognized characters into the memory  23  as the memo information is executed. Then, the process goes to step S 12 .  
         [0107]    In step S 12 , the process of searching whether or not the update information, which correspond to the set item of the database stored in the memory  23 , are contained in the memo information is executed. Then, the process goes to step S 13 .  
         [0108]    In step S 13 , it is decided whether or not the update information are contained in the memo information. If it is concluded that the update information are contained, the process goes to step S 14 . In contrast, in step S 13 , if it is concluded that the update information are not contained, the process goes to step S 19 .  
         [0109]    In step S 14 , the process of displaying the update indication screen of the database update information shown in FIG. 5 on the memo screen  32  is executed. Then, the process goes to step S 15 . In step S 15 , it is decided which one of an “update” button, which is used to update the information to the recognized characters, and a “not update” button, which is used not to update the information, is touch-input. If it is concluded that the “update” button is touch-input, the process goes to step S 16 . In contrast, in step S 15 , it is concluded that the “not update” button is touch-input, the process goes to step S 19 .  
         [0110]    In step S 16 , the process of displaying the “update information check” screen shown in FIG. 6 on the memo screen  32  is executed. Then, the process goes to step S 17 . In step S 17 , it is decided whether or not an “OK” button for updating the database by using the contents displayed on the memo screen  32  is touch-input. If it is concluded that the “OK” button is touch-input, the process goes to step S 18 .  
         [0111]    In contrast, in step S 17 , if it is concluded that the “OK” button is not touch-input, the process goes to step S 22 . In step S 22 , it is decided whether or not a “change” button that is used to change the displayed contents is touch-input. If it is concluded that the “change” button is touch-input, the process goes to step S 23 . In step S 23 , the process of changing the update person, the update item, etc. in compliance with the screen display is executed. After the change is ended, the process goes back to step S 17 . In contrast, in step S 22 , it is concluded that the “change” button is not touch-input, the process goes back to step S 17 .  
         [0112]    In step S 18 , the database updating process of updating the contents of the update items of the update person, which are displayed on the memo screen  32 , into the recognized character data is executed. Then, the process goes to step S 19 . In step S 19 , the process of switching the display screen  18   a,  which is split/displayed into the memo screen  32  and the navigation screen  33 , to one display screen of the navigation screen is executed. Then, the process is ended.  
         [0113]    Next, processing operations in the database correction executed by the navi control portion  10  in the navigation apparatus according to the embodiment (1) will be explained with reference to a flowchart shown in FIG. 14 hereunder.  
         [0114]    First, in step S 31 , in the “menu” screen shown in FIG. 7, it is decided whether or not a “database correction” button is touch-input. If it is concluded that the “database correction” button is not touch-input, the process is ended. In contrast, if it is concluded that the “database correction” button is touch-input, the process goes to step S 32 .  
         [0115]    In step S 32 , the process of displaying the correcting-database selection screen shown in FIG. 9 is executed. Then, the process goes to step S 33 . In step S 33 , it is decided whether or not the correcting database is touch-input. If it is concluded that the correcting database is not touch-input, the process is ended. In contrast, if it is concluded that the correcting database is touch-input, the process goes to step S 34 .  
         [0116]    In step S 34 , the process of displaying the correction screen of the database shown in FIG. 10 (in this case, first a name selection screen) is executed. Then, the process goes to step S 35 . In step S 35 , it is decided whether or not the name of the person to be corrected is touch-input. If it is concluded that the name is not touch-input, the process is ended. In contrast, if it is concluded that the name is touch-input, the process goes to step S 36 .  
         [0117]    In step S 36 , the process of displaying the correcting item selection screen shown in FIG. 11 is executed. Then, the process goes to step S 37 . In step S 37 , it is decided whether or not the item to be corrected is touch-input. If it is concluded that the item to be corrected is not touch-input, the process is ended. In contrast, if it is concluded that the item to be corrected is touch-input, the process goes to step S 38 .  
         [0118]    In step S 38 , the process of displaying the item correction screen shown in FIG. 12 is executed. Then, the process goes to step S 39 . In step S 39 , the process of displaying the corrected content being input in the item correction screen is executed. Then, the process goes to step S 40 .  
         [0119]    In step S 40 , it is decided whether or not an “end” button is touch-input. If it is concluded that the “end” button is not touch-input, the process is ended. In contrast, if it is concluded that the “end” button is touch-input, the process goes to step S 41 . In step S 41 , the process of updating the content of the selected set item into the corrected content is executed. Then, the process is ended.  
         [0120]    According to the navigation apparatus according to the above embodiment (1), when the incoming call or the outgoing call of the communication portion  19  is detected, the display screen  18   a  is split/displayed into the memo screen  32  and the navigation screen  33  and then the memo contents can be drawn/displayed by the handwriting via the touch panel  18   b  on the memo screen  32 . Hence, the user is not required to take out the writing paper, the writing tool, etc. every time and to prepare them previously, in order to take the notes. Therefore, the user can take notes easily and the convenience in use for the user can be improved.  
         [0121]    Also, the drawing data are recognized as the character data by the voice recognition portion  22 , and then the recognized character data are displayed on the memo screen  32 . Therefore, the user can check whether or not the character recognition has been executed precisely. Also, the recognized character data are stored as the memo information in the memory  23 . Therefore, a memory capacity can be reduced rather than a case where the drawing data are stored. Also, the character data that are subjected to the character recognition can be used positively in the application such as the update of the database stored in the memory  23 . As a result, the availability of the drawing data can be enhanced.  
         [0122]    Also, the searching process of extracting the character data, which correspond to the contents of the set items, from the character data, which are subjected to the character recognition, based on the character extraction keywords that are set beforehand to correspond to the set items of the database. Thus, if it is concluded that the update information are contained in the character data, such update information can be registered in the predetermined database. Therefore, a labor that is required of the user to input registered items separately and register them in the database can be omitted, and the navigation apparatus becomes serviceable and convenient of use for the user.  
         [0123]    Also, even if the wrong data are registered in the database, such wrong data can be corrected in compliance with the database correction screen and also necessary contents can be added later. Therefore, a precision of the information that are registered in the database stored in the memory  23  can be enhanced.  
         [0124]    Next, a navigation apparatus according to an embodiment (2) of the invention will be explained hereunder. FIG. 15 is a block diagram showing schematically a pertinent portion of the navigation apparatus according to the embodiment (2). In this case, the same symbols are affixed to the similar constituent parts to those in the navigation apparatus according to the embodiment (1) shown in FIG. 1, and thus their explanation will be omitted herein.  
         [0125]    A difference between the navigation apparatus according to the embodiment (2) and the navigation apparatus according to the embodiment (1) is that a voice recognition portion  24  is connected to a navi control portion  10   a  in place of the character recognition portion  22 . The character data that are voice-recognized by the voice recognition portion  24  are displayed as a memo (conversation memo) on the memo screen that is displayed in the split display mode after the system entered into the call mode. Also, different symbols are affixed to the navi control portion  10   a,  a drawing/display control portion  17   a,  and a memory  23   a,  which have different functions from those in the embodiment (1).  
         [0126]    The voice recognition portion  24  executes a process of recognizing the voice data, which are received by the voice input portion  21 , and the voice data, which are received by the communication portion  19 , as the character data based on the instruction issued from the navigation control portion  10   a.    
         [0127]    In procedures in the voice recognizing process executed by the voice recognition portion  24 , first a voice interval indicating an interval in which an target voice to be recognized is present is detected. Then, the voice analysis for analyzing features of the target voice to convert the voice into feature parameters is executed. Then, the phoneme recognition for separating the target voice into the phonemes or the syllables as the recognition unit of the voice to collate them with the phoneme patterns is executed. Then, the word recognition for combining the words based on the recognized results obtained at a phoneme or syllable level to collate them with a word dictionary is executed. Then, the paragraph recognition for assembling the paragraph based on results of the word recognition with regard to the syntax rule is executed. Then, the text recognition is executed by utilizing the wide-range knowledge such as the context, the meaning, etc. According to such process procedures, the precise voice recognition can be carried out.  
         [0128]    The memo information displayed on the memo screen based on the voice recognition, the databases (the phone book database, the destination database, etc.) constructed by the predetermined set items, the voice operation keywords used to execute processes of the predetermined operations such as the memo display start and the like by the voice recognition, and character extraction keywords used to extract the update information of the database from the character data that are subjected to the voice recognition are stored in the memory  23   a.    
         [0129]    The navi control portion  10   a  causes the display device  18  to split/display the display screen  18   a  into the memo screen and the navigation screen, and then reads the voice operation keyword stored in the memory  23   a.  Thus, the voice that is received by the voice input portion  21  is subjected to the voice recognition by the voice recognition portion  24 . Then, if the navi control portion  10   a  decides the character data, which is subjected to the voice recognition by the voice recognition portion  24 , coincide with the memo display starting keyword in the voice operation keywords, the navi control portion  10   a  issues an instruction to the drawing/display control portion  17   a  to display the character data, which is subjected to the voice recognition by the voice recognition portion  24 , on the memo screen.  
         [0130]    The drawing/display control portion  17   a  starts the process of displaying the character data on the memo screen in a conversational form, based on the instruction issued from the navi control portion  10   a.    
         [0131]    Also, the navi control portion  10   a  executes the process of storing the memo contents displayed on the memo screen into the memory  23  as the memo information, then reads the character extraction keyword from the memory  23  after the storing process, and then executes the process of extracting the character data, which relates to the character extraction keyword, from the memo information. Then, if the related character data are extracted, the process of updating the contents of the database, in which the set item associated with the character extraction keyword is provided, into the contents of the character data is executed.  
         [0132]    Also, the navi control portion  10   a  executes the process of registering the voice operation keywords and the character extraction keywords, and can execute the display of the register screen, the setting of the register keywords, etc.  
         [0133]    [0133]FIG. 16 to FIG. 27 are views showing examples displayed on the display screen  18   a  to explain utilization modes of the navigation apparatus according to the embodiment (2).  
         [0134]    [0134]FIG. 16 shows a display example in which the outgoing call of the communication portion  19  is detected while the navigation screen is being displayed to execute the route guidance to the destination. Outgoing call information  31   a  indicating that the outgoing call is detected is displayed on the display screen  18   a.    
         [0135]    Then, when the navigation apparatus entered into the call mode, the display screen  18   a  is shifted to the split display screen shown in FIG. 17. In the split display screen shown in FIG. 17, the display screen  18   a  is split/displayed into a memo screen  32   a,  on which the character data that are subjected to the voice recognition process can be displayed, and the navigation screen  33 , and then the voice that is received by the voice input portion  21  is voice-recognized. Then, if the received voice coincides with the voice operation keyword used to start the memo display based on the voice recognition, the display informing the user of the start of the voice recognition memo, for example, “the voice recognition memo is started” is displayed on the memo screen  32   a,  and then the memo taken based on the voice recognition is started.  
         [0136]    [0136]FIG. 18 shows a situation where the voice recognition memo is displayed on the memo screen  32   a.  The guide map for the guided routes is displayed continuously on the navigation screen  33 . The conversation memos that are subjected to the voice recognition are displayed on the memo screen  32   a,  and the character data of the other person in communication (paragraph contents indicated by the ear mark) and the character data of the user (paragraph contents indicated by the mouth mark) are displayed.  
         [0137]    Then, when a “record” button displayed on the memo screen  32   a  is touch-input, the contents displayed on the memo screen  32   a  are stored into the memory  23   a  as the memo information. Also, the character extraction keyword that is set previously is read from the memory  23   a,  and then the process of extracting the information that are associated with the character extraction keyword from the memo information is executed. Then, if the update information of the database stored in the memory  23   a  are contained in the memo information, the screen is shifted to a data extraction screen shown in FIG. 19.  
         [0138]    In the data extraction screen shown in FIG. 19, the name of the database in which the update information are contained (in this case, the “phone book database”), the name of the person who contains the update information, the update item, the update contents, and the operation buttons are displayed.  
         [0139]    Then, when a “DB update” button is touch-input, the database update process of rewriting the data into the displayed contents is executed. Then, after the update process of the database is executed, the display screen  18   a  is switched from the split display screen consisting of the memo screen  32   a  and the navigation screen  33  to one display screen of the navigation screen.  
         [0140]    Also, the user can register the voice operation keyword and the character extraction keyword stored in the memory  23   a.  First, when a “voice operation keyword registration” button provided on the menu screen shown in FIG. 20 is touch-input, the screen is shifted to a “voice operation keyword registration” screen shown in FIG. 21.  
         [0141]    In the “voice operation keyword registration” screen shown in FIG. 21, a “general registration” button and an “individual registration” button are displayed. When the “general registration” button is touch-input, the screen is shifted to a “general registration” screen shown in FIG. 22.  
         [0142]    In the “general registration” screen shown in FIG. 22, the voice operation keyword that is common to all other persons in communication can be registered. In this case, a “start memo display” process for starting the display of memo by the voice recognition and a “terminate voice recognition” process for terminating the display of the voice recognition and the memo are listed the recognition process. The voice operation keywords corresponding to respective processes can be registered.  
         [0143]    For example, when a “start memo display” button shown in FIG. 22 is touch-input to register the voice operation keyword of the memo display starting process, the screen is shifted to a “keyword registration for start memo display” screen shown in FIG. 23.  
         [0144]    In the “keyword registration for start memo display” screen shown in FIG. 23, a list of the memo-display start keywords that are set previously is displayed. Then, when a display button on which the predetermined keyword is written is touch-input and also a “registration” button is touch-input, the memo-display start keyword is registered.  
         [0145]    Also, in the “voice operation keyword registration” screen shown in FIG. 21, when the “individual registration” button is touch-input, the screen is shifted to an “individual registration” screen shown in FIG. 24.  
         [0146]    In the “individual registration” screen shown in FIG. 24, the voice operation keywords can be registered individually in response to the other person to/from which the call of the communication portion  19  is issued/received (the other person in communication). First, when a “select registrant” button is touch-input, the screen is shifted to a “select registrant” screen (not shown). For example, when the names of the registrants (the names of the persons registered in the phone book database) are scroll-displayed and the name of the registrant that should be individually registered is touch-input, the screen returns to FIG. 24. Thus, the selected registrant name is displayed on the right side of the “select registrant” button. Also, the setting of the recognizing process, etc. can be executed in the same way as the method explained in FIG. 22 and FIG. 23. The voice operation keywords can be registered individually every registrant via the “individual registration” screen.  
         [0147]    Also, in the “menu” screen shown in FIG. 20, when a “character extraction keyword registration” button is touch-input, the screen is shifted to a “character extraction keyword registration” screen shown in FIG. 25.  
         [0148]    In the “character extraction keyword registration” screen shown in FIG. 25, the “general registration” button and the “individual registration” button are displayed, like the screen shown in FIG. 21. In FIG. 25, when the “general registration” button is touch-input, the screen is shifted to a “general registration” screen shown in FIG. 26.  
         [0149]    In the “general registration” screen shown in FIG. 26, a list of the character extraction keywords is displayed. In this case, the character extraction keywords that are listed are the keywords as the broader term, and the keywords as the narrower term are further associated with respective keywords. Accordingly, the information that relate to the set items of the database can be extracted from the memo information without omission.  
         [0150]    Then, when the character extraction keyword to be used is touch-input (a plurality of character extraction keywords can be set) and also the “registration” button is touch-input, the selected keyword is registered as the character extraction keyword that is common to all the other persons in communication.  
         [0151]    Also, in FIG. 25, when the “individual registration” button is touch-input, the screen is shifted to the “individual registration” screen of the character extraction keyword shown in FIG. 27. In the “individual registration” screen shown in FIG. 27, like the “individual registration” screen of the voice operation keyword shown in FIG. 24, when the “select registrant” button is touch-input to select the predetermined registrant from the “select registrant” screen (not shown), then the character extraction keyword for the individual registration that is listed in FIG. 26 is touch-input (a plurality of character extraction keywords can be set), and then when the “registration” button is touch-input, the selected keyword is registered as the character extraction keyword peculiar to the selected registrant.  
         [0152]    Next, processing operations of a memo function executed by the navi control portion  10   a  in the navigation apparatus according to the embodiment (2) will be explained with reference to a flowchart shown in FIG. 28 hereunder. In this case, since processes in steps S 51  to S 54  are similar to the processes in steps S 1  to S 4  shown in FIG. 14, their explanation will be omitted herein.  
         [0153]    In step S 54 , the process of splitting/displaying the display screen  18   a  into the memo screen  32   a  and the navigation screen  33  shown in FIG. 17 is executed. Then, the process goes to step S 55 . In step S 55 , the process of reading the voice operation keyword from the memory  23   a  is executed. Then, the process goes to step S 56 .  
         [0154]    In step S 56 , the process of starting the voice recognizing process that recognizes the voice data, which are received by the voice input portion  21 , and the voice data of the other person in communication, which are received by the communication portion  19 , as the character data is executed. Then, the process goes to step S 57 .  
         [0155]    In step S 57 , it is decided whether or not the voice, which is received by the voice input portion  21  and is subjected to the voice recognition by the voice recognition portion  24 , coincided with the voice operation keyword for the memo display start. If it is concluded that the voice does not coincide with the voice operation keyword for the memo display start, the process returns to step S 57 . In contrast, if it is concluded that the voice coincided with the voice operation keyword for the memo display start, the process goes to step S 58 .  
         [0156]    In step S 58 , the process of displaying the character data, which are subjected to the voice recognition, on the memo screen  32   a  is executed. Then, the process goes to step S 59 . In step S 59 , it is decided whether or not the voice, which is received by the voice input portion  21  and is subjected to the voice recognition by the voice recognition portion  24 , coincided with the voice operation keyword used to end the voice recognition of the memo display. If it is concluded that the voice does not coincide with the voice operation keyword used to end the voice recognition, the process goes back to step S 58 . In contrast, in step S 59 , it is concluded that the voice coincided with the voice operation keyword used to end the voice recognition, the process goes back to step S 60 .  
         [0157]    In step S 60 , it is decided which one of the “record” button, which is used to store the memo contents displayed on the memo screen  32   a  in the memory  23   a  as the memo information, and the “cancel” button, which is used to cancel the memo information displayed on the memo screen, is touch-input. If it is concluded that the “record” button is touch-input, the process goes to step S 61 . In contrast, in step S 60 , it is concluded that the “cancel” button is touch-input, the process goes to step S 68 .  
         [0158]    In step S 61 , the process of storing the voice-recognized memo information into the memory  23   a  is executed. Then, the process goes to step S 62 . In step S 62 , the process of reading the character extraction keyword from the memory  23   a  is executed. Then, the process goes to step S 63 . In step S 63 , the process of extracting the character data, which relates to the character extraction keyword, from the character data that are subjected to the voice recognition is executed. Then, the process goes to step S 64 .  
         [0159]    In step S 64 , it is decided whether or not the update information of the database, which are stored in the memory  23   a,  are contained in the extracted character data. If it is concluded that the update information of the database are contained, the process goes to step S 65 . In contrast, in step S 64 , if it is concluded that the update information of the database are not contained, the process goes to step S 68 .  
         [0160]    In step S 65 , the process of displaying the extracted update information of the database shown in FIG. 19 is executed. Then, the process goes to step S 66 . In step S 66 , it is decided which one of a “DB update” button and a “DB not-update” button displayed on the memo screen  32   a  is touch-input. If it is concluded that the “DB update” button is touch-input, the process goes to step S 67 . In contrast, in step S 66 , if it is concluded that the “DB not-update” button is touch-input, the process goes to step S 68 .  
         [0161]    In step S 67 , the database updating process, i.e., the process of updating the database the contents of the set items in the database shown in FIG. 19 into the contents of the extracted character data is executed. Then, the process goes to step S 68 .  
         [0162]    In step S 68 , the process of switching the display screen  18   a,  which is split into the memo screen  32   a  and the navigation screen  33 , into one display screen of the navigation screen is executed. Then, the process is ended.  
         [0163]    Next, processing operations in the voice operation keyword registration executed by the navi control portion  10   a  in the navigation apparatus according to the embodiment (2) will be explained with reference to a flowchart shown in FIG. 29 hereunder.  
         [0164]    First, in step S 71 , it is decided whether or not the “voice operation keyword registration” button is touch-input into the “menu” screen shown in FIG. 20. If it is concluded that the “voice operation keyword registration” button is not touch-input, the process is ended. In contrast, if it is concluded that the “voice operation keyword registration” button is touch-input, the process goes to step S 72 .  
         [0165]    In step S 72 , the process of displaying the “voice operation keyword registration” screen shown in FIG. 21 is executed. Then, the process goes to step S 73 . In step S 73 , it is decided which one of the “general registration” button and the “individual registration” button displayed on the display screen  18   a  in FIG. 21 is touch-input. If it is concluded that the “general registration” button is touch-input, the process goes to step S 74 .  
         [0166]    In step S 74 , the process of displaying the “general registration” screen shown in FIG. 22 is executed. Then, the process goes to step S 75 . In step S 75 , the process of registering the general registration keyword, which corresponds to each recognizing process shown in FIG. 22, is executed based on the instruction that is input by the user. Then, the process goes to step S 76 .  
         [0167]    In step S 76 , it is decided whether or not the “end” button is touch-input. If it is concluded that the “end” button is not touch-input, the process is ended. In contrast, if it is concluded that the “end” button is touch-input, the process goes to step S 77 .  
         [0168]    In step S 77 , the process of updating/storing the voice operation keyword, which is generally registered newly, into the memory  23   a.  Then, the process is ended.  
         [0169]    In contrast, in step S 73 , if it is concluded that the “individual registration” button is touch-input, the process goes to step S 78 .  
         [0170]    In step S 78 , the process of displaying the “individual registration” screen shown in FIG. 24 is executed. Then, the process goes to step S 79 . In step S 79 , the process of registering the registration keyword, which corresponds to the registrant selecting process and each recognizing process shown in FIG. 24, is executed based on the instruction that is input by the user. Then, the process goes to step S 80 .  
         [0171]    In step S 80 , it is decided whether or not the “end” button is touch-input. If it is concluded that the “end” button is not touch-input, the process is ended. In contrast, if it is concluded that the “end” button is touch-input, the process goes to step S 81 .  
         [0172]    In step S 81 , the process of updating/storing the voice operation keyword, which is individually registered newly, in the memory  23   a  is executed. Then, the process is ended.  
         [0173]    In this case, the registration of the character extraction keyword is also carried out by the almost same processing operation as the processing operation explained as above.  
         [0174]    According to the navigation apparatus according to the above embodiment (2), when the incoming call or the outgoing call of the communication portion  19  is detected, the display screen  18   a  is split/displayed into the memo screen  32   a  and the navigation screen  33 . Then, the process of starting the memo display is executed when the voice input portion  21  receives the voice corresponding to the voice operation keyword. Then, the character data that are subjected to the voice recognition by the voice recognition portion  24  are displayed on the memo screen  32   a  as the memo contents. Therefore, in order to take the notes, the user is not required to take out the writing paper, the writing tool, etc. every time and to prepare them previously. Thus, the user can take notes easily by the voice. Also, since the operation to use the memo function can be executed by the voice, the operability can be improved and also the convenience in use for the user can be further improved.  
         [0175]    Also, the voice data received via the voice input portion  21  and the voice data received via the communication portion  19  are recognized by the voice recognition portion  24 , and then stored in the memory  23   a  as the character data. Therefore, the memory capacity can be reduced rather than the case where the voice data are stored as it is. Also, the voice-recognized character data can be practically used in the application such as the update of the database, etc. As a result, availability of the voice data can be enhanced.  
         [0176]    Also, since the user can register the voice operation keyword and the character extraction keyword that are common to the other person in communication, the generalization of the voice operation can be achieved. Also, since the common character data that are associated with the character extraction keyword are extracted from the memo information, the update of the database can be executed appropriately. Therefore, the labor required of the user to register registration items in the database by the separate inputting can be omitted, and the navigation apparatus becomes serviceable and convenient of use for the user.  
         [0177]    Also, the voice operation keyword and the character extraction keyword may be registered individually by the user according to the other person in communication. Also, this navigation apparatus may deal with various applications of the user by changing the voice operation keyword and the character extraction keyword according to the other person in communication.  
         [0178]    In this case, in the above embodiment (2), the case where the character data that are subjected to the voice recognition by the voice recognition portion  24  are displayed on the memo screen  32   a  as the memo contents is explained. However, in another embodiment, the character recognition portion  22  explained in FIG. 1, the voice recognition portion  24 , an inputting portion that can select one of these recognizing portions may be provided. The screen may be switched into the memo screen on which memo contents can be input by the handwriting or the memo screen on which memo contents can be input by the voice, in response to the selection input of the user.  
         [0179]    In still another embodiment, the character recognition portion  22 , the voice recognition portion  24 , and a switching portion, which can switch automatically settings in these recognizing portions in response to the running situation, may be provided. The memo screen on which memo contents can be input by the voice may be set while the vehicle into which the navigation apparatus is installed is running. On the other hand, the memo screen on which memo contents can be input by the handwriting may be set during when the vehicle is stopped.
