  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram showing a configuration of a schedule management apparatus according to the first embodiment of the present invention. In the present embodiment, the schedule management device 10 is a portable terminal such as a PDA, and includes a CPU 11, an input unit 12, a display unit 13, an input interface (I / F) 14, a RAM 15, a ROM 16, and a large-scale storage device 17. And a microphone 18.

  The CPU 11 executes control of the entire schedule management apparatus 10, processing for responding to voice data input via the microphone 18 and the input I / F 14, processing based on turning on of a switch included in the input unit 12, and the like. The input unit 12 includes switches and the user can input various information. The switch of the input unit 12 may be in the form of a so-called full keyboard, or may be in a form in which a kana is assigned to the numeric keypad by the kana turning method. The display unit 13 includes a liquid crystal display device, and can display data in a schedule database to be described later.

  The ROM 16 stores programs such as voice processing, language analysis processing, registration / retrieval processing executed by the CPU 11 of the schedule management apparatus 10. The RAM 15 temporarily stores a program read from the ROM 16 and stores data generated during the process executed by the CPU 11. The large-scale storage device 17 includes a removable memory card and hard disk, and stores a schedule database. The input I / F 14 is connected to the microphone 18 and D / A converts the audio signal input from the microphone 18 to generate audio data.

  In the present embodiment, the schedule management apparatus is in the form of a portable terminal, but the present invention is not limited to this, and the schedule management apparatus according to the present invention may be incorporated in a normal personal computer.

  FIG. 2 is a block diagram showing functions of the schedule management apparatus according to the present embodiment. As shown in FIG. 2, the schedule management apparatus 10 according to this exemplary embodiment includes a voice processing unit 21, a language analysis unit 22, a registration / search determination unit 23, and a schedule registration / search unit 24. The audio processing unit 21 detects the level of the audio signal from the microphone 18 and starts D / A conversion to generate audio data when the audio signal reaches a predetermined level. For example, the generation of audio data is continued until the audio signal becomes lower than a predetermined level for a predetermined time.

  The language analysis unit 22 accepts the voice data obtained by the voice processing unit 21, performs language analysis on the voice data, and specifies a character string (word) input by the user. Further, the registration / search determination unit 23 determines whether to register data in the schedule database (DB) 26 or search the schedule DB 26 based on the word specified by the language analysis unit 22. The schedule registration / search unit 24 accesses the schedule DB 26 based on the determination result of the registration / search determination unit 23 and executes processing such as data registration and data search. The processing result of the schedule registration / search unit 24 is displayed on the screen of the display unit 13. Also, in the processing by the voice processing unit 21 and the language analysis unit 22, an image is displayed on the screen of the display unit 13 as necessary.

  In FIG. 2, the function of the audio processing unit 21 is mainly realized by the CPU 11 and the input I / F 14 of FIG. The functions of the language analysis unit 22, the registration / search determination unit 23, and the schedule registration / search unit 24 are mainly realized by the CPU 11.

Processing executed in the schedule management apparatus 10 configured as described above will be described. 3 to 5 are flowcharts showing search / registration processing executed in the schedule management apparatus according to this embodiment. In the present embodiment, CPU 1
1 (registration / search determination unit 23) is a second state in which the character string input by voice and recognized by the language analysis unit 22 includes the date and time, and the schedule contents, or the language analysis unit 22 A recognized character string includes a date and time, or a date containing only a date .
It is determined which of the following states. Thereafter, the CPU 11 (schedule registration / search unit 24) searches the schedule DB 26 in the first state, and generates a record of schedule data and stores it in the schedule DB 26 in the second state. Hereinafter, the search / registration process will be described in more detail.

  As shown in FIG. 3, the CPU 11 executes initialization processing such as clearing data in the RAM 25 and clearing the screen of the display unit 13 (step 301). Next, the CPU 11 (audio processing unit 21) determines whether or not an audio signal is input from the microphone 18 at the input I / F 14 (step 302). If YES is determined in step 302, the input I / F 14 performs D / A conversion on the audio signal in accordance with an instruction from the CPU 11, generates audio data, and stores the audio data in a predetermined area of the RAM 15 ( Step 303). In the processing from step 302 to step 303, an audio signal of a certain level or higher is input to the input I / F 14 and D / A converted, and audio data is generated and stored in the RAM 15 as long as the audio signal is higher than a predetermined level. The

  Next, the CPU 11 (language analysis unit 22) reads the voice data stored in the RAM 15 and executes language analysis processing for specifying a character string included in the voice data (step 304). In the language analysis process, the language analysis unit 22 uses a technique such as morphological analysis to specify a word that is a noun or a character or character string of another part of speech. Since a well-known method may be applied to the language analysis processing, detailed description is omitted.

  The CPU 11 (registration / search determination unit 23) determines whether or not the character string (word) specified by the language analysis process is a date (step 305). More specifically, the language analysis unit 22 determines whether or not the character string obtained by the language analysis processing includes a reading of “× month × day” or “*** year × month × day”. That's fine. If it is determined Yes in step 305, the registration / search determination unit 23 temporarily stores the specified date in the RAM 15 and sets the date flag provided in the RAM 15 to “1” (step 1). 306). Also, the registration / search determination unit 23 initializes and starts a timer (step 307).

  In steps 302 to 307, a series of voices input by the user is recognized, and if the input voice is a date, a date flag is set.

  If it is determined No in step 302, the registration / search determination unit 23 determines whether the timer is being counted (step 308). If “No” is determined in step 308, the process returns to step 302. On the other hand, when it is determined Yes in step 308, the registration / search determination unit 23 determines whether or not a predetermined minimum unit time for incrementing the timer has elapsed (step 309). If it is determined Yes in step 309, the timer value (timer value) is incremented (step 310). If it is determined No in step 309, the process returns to step 302.

  Further, the registration / search determination unit 23 refers to the timer value to determine whether or not a predetermined time has elapsed since the timer start (step 311). If it is determined No in step 311, the process returns to step 302. On the other hand, if it is determined Yes in step 311, the registration / search determination unit 23 stops the timer (step 312) and proceeds to step 501 in FIG. 5. The process after step 501 in FIG. 5 is a search process of the schedule DB 26 in the large-scale storage device 17 and will be described in detail later.

  The case where No is determined in step 305 will be described below. When it is determined No in step 305, the registration / search determination unit 23 determines whether or not the character string (word) specified by the language analysis processing is time (step 401). When it is determined Yes in step 401, the registration / search determination unit 23 refers to the RAM 15 and determines whether or not the date flag is set to “1” (step 402). If it is determined Yes in step 402, the registration / search determination unit 23 temporarily stores the specified date in the RAM 15 and sets the time flag provided in the RAM 15 to “1” (step 1). 403). Also, the registration / search determination unit 23 initializes and starts a timer (step 404). In this embodiment, since it is assumed that the date is input before the time is input, the registration / search determination unit 23 sets the date flag to “1” in step 402. I'm investigating.

  When it is determined No in step 401, the registration / search determination unit 23 determines whether or not the character string (word) specified by the language analysis process is the schedule content (step 405). For example, a plurality of words (“meeting”, “business trip”, “visitor”, “seminar”) are stored in advance in the ROM 16 and RAM 15 as schedule contents, and the registration / search determination unit 23 specifies the language analysis process. It suffices to determine which one of the words corresponds to.

  If it is determined Yes in step 406, the registration / search determination unit 23 determines whether the date flag is “1” and the time flag is “1” (step 406). That is, prior to inputting the schedule contents, it is determined whether the date and time have already been input. If it is determined Yes in step 406, the CPU 11 (schedule registration / search unit 24) stops the timer (step 407), and based on the date and time temporarily stored in the RAM 15 and the schedule contents. Then, a record of schedule data to be stored in the schedule DB 26 is generated and stored in the schedule DB 26 (step 408).

  FIG. 6 is a diagram showing an example of the structure of schedule data in the schedule DB according to the present embodiment. As shown in FIG. 6, the record of the schedule data 600 in the schedule DB 26 has items of date, time zone, and schedule content. For example, the record 601 includes a date “April 1”, a time zone “9:00 to 11:00”, and a schedule content “conference”. In the present embodiment, the date and time are input by voice and temporarily stored in the RAM 15. Here, the input date corresponds to the date in the record of the schedule data. On the other hand, the input time corresponds to the time zone start time in the schedule data record.

  For the end time of the time zone, for example, a time length (1 hour for a visitor, 2 hours for a conference, 5 hours for a business trip or seminar, etc.) is set for each schedule content. Are stored in the ROM 16 and the RAM 15. Therefore, the schedule registration / retrieval unit 24 can calculate the end time by adding the time length associated with the schedule content to the start time. The schedule registration / search unit 24 may store the start time and the calculated end time in the schedule DB 26 as a time zone.

  The schedule registration / search unit 24 displays the record of the registered schedule data on the screen of the display unit 13 (step 409). Thereafter, the schedule registration / retrieval unit 24 clears the date flag and the time flag to “0” (step 410).

  Next, processing following the timer stop in step 312 will be described. The CPU 11 (registration / search determination unit 23) determines whether or not the date flag in the RAM 15 is “1” (step 501). If it is determined No in step 501, the process returns to step 302. On the other hand, if it is determined Yes in step 501, the registration / search determination unit 23 determines whether or not the time flag in the RAM 15 is “0” (step 502). The determination of Yes in step 502 means that there has been no voice input of time within a predetermined time after the date is input by voice. On the other hand, No in step 502, that is, that the time flag is “1” means that the time is input by voice following the voice input of the date, and then there is no other voice input within a predetermined time. It means that.

  If YES is determined in step 502, the CPU 11 (schedule registration / search unit 24) searches the schedule DB 26 based on the date specified by the language analysis and temporarily stored in the RAM 15 (step 503). . In step 503, the schedule registration / retrieval unit 24 finds a record having a date that coincides with a date that is input by voice and temporarily stored in the RAM 15 in the schedule data of the schedule DB 26. The schedule registration / search unit 24 generates an image of a search result including the record of the schedule data found in step 503 and displays it on the screen of the display unit 13 (step 504). Thereafter, the schedule registration / retrieval unit 24 clears the date flag to “0” (step 505).

  On the other hand, if it is determined No in step 502, the schedule registration / retrieval unit 24 searches the schedule DB 26 based on the date and time specified by language analysis and temporarily stored in the RAM 15 (step). 506). In step 506, the schedule registration / retrieval unit 24 is input by voice in the time zone among records having a date that matches the date that is voice-input and temporarily stored in the RAM 15 in the schedule data of the schedule DB 26. Thus, a record including the time temporarily stored in the RAM 15 is found. The schedule registration / search unit 24 generates an image of the search result including the record of the schedule data found in step 506 and displays it on the screen of the display unit 13 (step 507). Thereafter, the schedule registration / retrieval unit 24 clears the date flag and time flag to “0” (step 508).

  As described above, when only the date is input by voice, a list of schedule data records having the same date is displayed on the screen of the display unit 13. On the other hand, when the date and time are input by voice, the record of the schedule data specified by the date and time, that is, the schedule to be performed on the date and time is displayed on the screen of the display unit 13. The

  In this embodiment, after a date is input by voice, if there is no voice input for a predetermined time (Yes in step 311 in FIG. 3 and Yes in steps 501 and 502 in FIG. 5), the date is input. The search process is executed using the date, and the schedule content having the date is displayed on the screen of the display unit 13 together with the time zone. FIG. 7A is a diagram illustrating an example of a search result displayed on the screen of the display unit 13. In the example of FIG. 7A, the date “April 11” is input by voice, and the CPU 11 recognizes the input date and searches the schedule data in the schedule DB 26 shown in FIG. A record containing the date "11 days" is found. Therefore, in the image 701 shown in FIG. 7A, the contents of the found record are displayed. As described above, in this embodiment, it is possible to confirm the schedule of a date simply by inputting a desired date by voice.

  In addition, when a date is input by voice within a predetermined time after the date is input by voice, and there is no voice input for a predetermined time thereafter (Yes in step 311 in FIG. 3, in step 501 in FIG. 5). Yes, No in step 502), the search process is executed using the input date and time, and the schedule content of the record that includes the input time and the time zone includes the input time. It is displayed on the screen of the display unit 13 together with the band. FIG. 7B is a diagram illustrating an example of a search result displayed on the screen of the display unit 13. In the example of FIG. 7B, the date “April 11” and the time “14:00” are input by voice, and the input date and time are recognized by the CPU 11, and the date “April 11” is changed. A record that includes a record that includes “14:00 (14:00)” is found. Therefore, in the image 702 shown in FIG. 7B, the contents of the found record are displayed.

  FIG. 7C is a display example of a record of schedule data stored in the schedule DB 26 by voice input. In this example, the date “April 15”, the time “10 o'clock (10:00)”, and the schedule content “meeting” are input by voice, and a record according to the date, time, and schedule content input by voice is obtained. Are generated in the schedule DB 26. In the image 703 shown in FIG. 7C, the contents of the generated record are displayed.

  When it is detected that the user operates the input unit 12 to turn on the return designation switch in the input unit 12 (step 509), the schedule registration / inspection unit 24 is displayed on the screen of the display unit 13. The image is cleared (step 510), and the process returns to step 302.

  According to the present embodiment, the language analysis unit 22 determines whether the recognized character string is in the first state including either the date or the date and time, whether the date or the date and time. And whether the second state includes the schedule content. In the first state, the schedule registration / search unit 24 searches the schedule DB 26 to read a date or a record related to the date and time, and displays the contents of the record on the screen of the display unit 13. indicate. On the other hand, in the second state, the schedule registration / search unit 24 generates a record of schedule data including the date for recognition, the time zone based on the time, and the schedule contents, and stores the record in the schedule DB 26. To do. Therefore, a specific instruction for schedule registration or schedule search, for example, switch-on or schedule input or schedule registration can be realized appropriately without the need for voice input for the specification. .

  In the present embodiment, the registration / search determination unit 23 determines whether the voice-recognized character string is only a date, or a date and time. When the character string is a date, the schedule registration / search unit 24 searches the schedule DB 26, reads a record including the date, displays the content of the read record, and the character string is the date and time. In this case, a record that includes the date and whose time zone includes the time in the character string is read, and the contents of the read record are displayed. With this configuration, the user can obtain a desired search result by inputting a desired voice.

  In the present embodiment, the registration / search determination unit 23 determines that the recognized character string is a time within a predetermined time after the recognized character string is determined to be a date, and then further determines the predetermined character string. If the recognized character string is determined to be the schedule content within the time, it is determined as the second state. On the other hand, the registration / search determination unit 23 determines the first state when the character string is not recognized within a predetermined time or when it is determined that the recognized character string is not the schedule content. . With this configuration, since it is sufficient to recognize a relatively simple and short word, the determination of the first state and the second state can be realized without complicating the recognition of the character string by language analysis. it can.

  Further, in the present embodiment, for each schedule content, a predetermined time length is associated and stored in a storage device such as the ROM 16 or the RAM 15, and the schedule registration / search unit 24 uses the recognized time as a start time. The time obtained by adding the time length associated with the schedule content is calculated as the end time, and the start time and the end time are set as the time zones in the record data. Thereby, it is possible to generate a record of appropriate schedule data with a simple input.

  Next, a second embodiment of the present invention will be described. In the first embodiment, three items of date, time, and schedule content are input by voice, and appropriate for each of date input, date and time input, and date, time, and schedule content input. Processing is being executed. In the second embodiment, the date and time are continuously input almost simultaneously, and predetermined processing is executed for each of the date and time input, the date and time, and the schedule content input.

  The configuration and functions of the schedule management device according to the second embodiment are the same as those shown in FIGS. Also, in the process executed in the schedule management apparatus according to the second embodiment, a process substantially equivalent to that in FIG. 3 is executed. Therefore, in FIG. 3, processing steps different from those of the first embodiment will be described, and description of similar processing steps will be basically omitted.

  In the second embodiment, in step 305 of FIG. 3, the CPU 11 (registration / search determination unit 23) determines whether or not the character string (word) specified by the language analysis processing is a date and time. (Step 305). More specifically, the language analysis unit 22 reads the character string obtained by the language analysis process as “× month × day ○ hour ○ minute” or “*** year × month × day ○ hour ○ minute”. It may be determined whether or not it is included. If YES is determined in step 305, the registration / search determination unit 23 temporarily stores the specified date and time in the RAM 15 and sets a date flag provided in the RAM 15 to “1”. (Step 306). Also, the registration / search determination unit 23 initializes and starts a timer (step 307).

  FIG. 8 is a flowchart showing search / registration processing executed in the schedule management apparatus according to the second embodiment, and describes processing steps subsequent to the processing steps of FIG. If it is determined No in step 305 of FIG. 3, the registration / search determination unit 23 determines whether the character string (word) specified by the language analysis process is the schedule content (step 804). . Similarly to the first embodiment, in the second embodiment, a plurality of words (“meeting”, “business trip”, “visitor”, “seminar”) are stored in the ROM 16 and RAM 15 in advance as schedule contents. In addition, the registration / search determination unit 23 may determine which of the words identified by the language analysis process corresponds to the word.

  If it is determined Yes in step 804, the registration / search determination unit 23 determines whether or not the date flag is “1” (step 805). That is, prior to inputting the schedule contents, it is determined whether the date and time have already been input. When it is determined Yes in step 805, the CPU 11 (schedule registration / search unit 24) stops the timer (step 806), and based on the date and time temporarily stored in the RAM 15 and the schedule contents. Then, a record of schedule data to be stored in the schedule DB 26 is generated and stored in the schedule DB 26 (step 807).

  In the schedule data record, for the end time of the time zone, as in the first embodiment, the end time is calculated by adding the time set for each schedule content to the start time, and the start time and end time However, what is necessary is just to store in schedule DB26 as a time slot | zone.

  The schedule registration / search unit 24 displays the record of the registered schedule data on the screen of the display unit 13 (step 808). Thereafter, the schedule registration / retrieval unit 24 clears the date flag and the time flag to “0” (step 811).

  If it is determined No in step 312, the CPU 11 (schedule registration / retrieval unit 24) searches the schedule DB 26 based on the date and time specified by language analysis and temporarily stored in the RAM 15 (step S31). 801).

  In step 801, the schedule registration / retrieval unit 24 finds a record (first record) having a date that coincides with the date inputted by voice and temporarily stored in the RAM 15 in the schedule data of the schedule DB 26, and Among the found first records, a record (second record) is found that includes the time when the voice is input and temporarily stored in the RAM 15 in that time zone. That is, the first record including the date when the voice is input and the second record including the time when the voice is input with the name are found.

  The schedule registration / search unit 24 generates an image of a search result including the first record of the schedule data found in step 802, and the second record is different from other records in the image. It displays on the screen of the display part 13 as a mode which shows different emphasis (step 802). In step 802, a record relating to the time when the voice is input is particularly highlighted. Different colors, bold letters, and the like correspond to the mode of emphasis. Thereafter, the schedule registration / retrieval unit 24 clears the date flag to “0” (step 803).

  When it is detected that the user has operated the input unit 12 to turn on the return designation switch in the input unit 12 (step 810), the schedule registration / inspection unit 24 is displayed on the screen of the display unit 13. The image is cleared (step 811), and the process returns to step 302.

  FIG. 9 is a diagram illustrating an example of a search result displayed on the screen of the display unit 13. In the example of FIG. 7A, the date and time “April 11, 14:00” are input by voice, and the CPU 11 recognizes the input date and time, and the schedule in the schedule DB 26 shown in FIG. The data is searched to find a first record that includes the date “April 11” and a second record that includes “14:00” in the time zone in the first record. Accordingly, in the image 901 shown in FIG. 9, the content of the found first record is displayed, and the second record (see reference numeral 902) is an aspect (in this example, bold) that is different from the other records. ) Is displayed. As described above, in the second embodiment, by simply inputting a desired date and time by voice, the user can display the schedule of the date and the record corresponding to the voiced time in an emphasized manner. This can be confirmed easily.

  According to the second embodiment, the registration / search determination unit 23 determines whether the recognized character string is a date, or a date and time. Further, when the character string is a date, the schedule registration / search unit 24 searches the schedule DB 26, reads a record including the date, and displays the content of the record on the screen of the display unit 13. On the other hand, when the character string is a date and time, the first record including the date is read, and the second record whose time zone includes the recognized time is specified, and the second record The content of the record is displayed on the screen of the display unit 13 in a display mode different from the other records in the first record, for example, the color is changed or bold. As a result, when not only the date but also the time is input by voice, the schedule content of the time zone related to the input time is displayed in a different display mode in the schedule of the date, and the user can easily Can be confirmed.

  Further, according to the second embodiment, the registration / search determination unit 23 determines that the recognized character string is the schedule content within a predetermined time after the recognized character string is determined as the date and time. If so, the second state is determined. On the other hand, the registration / search determination unit 23 determines the first state when the character string is not recognized within a predetermined time or when it is determined that the recognized character string is not the schedule content. . With this configuration, since it is sufficient to recognize a relatively simple and short word, the determination of the first state and the second state can be realized without complicating the recognition of the character string by language analysis. it can.

  Next, a third embodiment of the present invention will be described. In the first embodiment and the second embodiment, the date and time are input for registration in the schedule DB 26. That is, in one input, the schedule contents are registered in the schedule DB 26 only at a specific time (time zone) on a specific date. In the third embodiment, similar schedule contents can be registered at a certain time (time zone) in a specific period.

  The configuration of the schedule management apparatus according to the third embodiment is the same as that shown in FIG. The functional block diagram of the schedule management apparatus according to the third embodiment is also the same as that shown in FIG.

  In the search / registration process of the management apparatus according to the third embodiment, the steps shown in the flowchart of FIG. 3 are executed. In the first embodiment, if it is determined No in step 305, that is, if it is determined that the character string (word) specified by the language analysis processing is not a date, the process proceeds to step 401 in FIG. It was out. In the third embodiment, if “No” is determined in step 305, the process proceeds to step 1001 in FIG.

  In the third embodiment, in step 305, it is determined Yes when only the date is included in the character string (word) specified by the language analysis process, and for example, the date and the period are included. If it is, it is determined No.

  FIG. 10 is a flowchart illustrating search / registration processing executed in the schedule management apparatus according to the third embodiment. When it is determined No in step 305 of FIG. 3, the registration / search determination unit 34 determines whether or not a period is included in the character string specified by the language analysis processing (step 1001). For example, if the word indicating the period is listed and stored in the ROM 16 or the RAM 15, the registration / search determination unit 23 determines in step 1001 which of the words identified by the language analysis processing corresponds to it. good. FIG. 11A is a diagram illustrating an example of a word list indicating a period. As shown in FIG. 11A, the list 1101 includes words indicating a period such as “this week”, “next week”, “1 week”, “2 weeks”, and the like.

  If it is determined No in step 1001, the process proceeds to step 401 in FIG. 4, and the same processing as in the first embodiment is performed. If it is determined Yes in step 1102, it is determined whether or not the start time specific word is included in the character string specified by the language analysis process (step 1002). In the present embodiment, both the case where only “period” is input and the case where “start time specific word” and “period” are input are assumed.

  When “start time specific word” and “period” are input, for example, “a specific time” such as “one week from today” is input, and after the case particle “from”, “a specific period” "Is entered. For example, if the start time specific words are listed and stored in the ROM 16 or the RAM 15, the registration / search determination unit 23 determines in step 1002 which of the words specified by the language analysis processing corresponds to it. good.

  FIG. 11B is a diagram illustrating an example of a list of start time specific words and a list of words indicating a period. As shown in FIG. 11B, the start time specific word list 1111 includes words meaning a specific time, such as “today” and “tomorrow”. Therefore, if the word included in the list 1111 and the word included in the word list 1112 indicating the period are connected by the case particle “kara”, “Yes” is determined in step 1002. Furthermore, in the third embodiment, when a specific date (for example, “March 9”) and a period are connected by a case particle “kara” (for example, “March 9”). “One week from the day”) is also determined as Yes in step 1002.

  When it is determined No in step 1002, that is, when only the period is included in the character string specified by the language analysis processing, the registration / search determination unit 34 acquires today's date and acquires it. The start date is specified from the today's date and period that have been set (step 1004). Here, the start date corresponds to the start date (start) of the period input by the user. Next, the registration / search determination unit 34 specifies a corresponding date from the start date and the number of days indicated by the period (step 1005).

  For example, when there is the following input, steps 1001 and 1002 to 1005 are performed. This is a case where today's date is February 24, 2009, and the input and recognized period is “next month”. In this case, the start date is March 1, 2009, and each day from March 1, 2009 to March 31 is the corresponding date. Through step 1005, one or more dates are determined. The date obtained in step 1005 is stored in the RAM 15.

  When it is determined Yes in step 1002, the registration / search processing unit 34 determines whether or not the start time specific word is a date (step 1006). If it is determined Yes in step 1006, the date in the start time specifying word is set as the start date (step 1007), and the corresponding date is specified from the start date and the number of days indicated by the period (step 1005).

  For example, if there is an input such as the following, steps 1001, 1002, 1006, 1007 and 1005 are performed. This is the case where today's date is February 24, 2009, and the input and recognized character string is "3 days from March 2". In this case, it is determined that the start time specific word is “March 2” and the period is “3 days”, and each day from March 2 to March 4 is the corresponding date.

  If NO in step 1006, the registration / search processing unit 34 acquires today's date (step 1008), and specifies the start date and time from the start time specifying word and today's date (step 1009). . Thereafter, the registration / search processing unit 34 specifies a corresponding date from the start date and the number of days indicated by the period (step 1005).

  For example, if there is an input such as the following, steps 1001, 1002, 1006, 1008, 1009, and 1005 are performed. This is a case where today's date is February 24, 2009, and the input and recognized character string is “one week from the next week”. In this case, it is determined that the start time specific word is “next week” and the period is “one week”, and each day from March 8 to March 14 becomes the corresponding date.

  Thus, according to the third embodiment, one or more dates can be input according to the period or the start time specifying word and the period. As a result, when it is desired to register the same schedule contents for a series of dates included in a certain period, it is possible to input a desired series of dates without the need to input each date.

  After step 1005 is executed, the process proceeds to step 306 in FIG. 3, where the registration / search determination unit 23 temporarily stores the specified date in the RAM 15 and sets the date flag provided in the RAM 15 to “1”. (Step 306), and the timer is initialized and started (step 307).

  If NO in step 1001, the process proceeds to step 401, where the registration / search determination unit 23 determines whether or not the character string (word) specified by the language analysis process is time ( Step 401). Thereafter, time recognition (steps 402 to 404), schedule content recognition (steps 405 to 407), and date, time, and schedule content registration (step 408) are performed.

  FIG. 12A is a diagram illustrating an example of schedule data in the schedule DB when today's date is February 24, 2009 and the input and recognized period is “next month”. It is. In this example, “9:00” is input as time and “conference” is input and recognized as schedule contents. In this example, in the schedule data 1201, it is stored in the schedule DB 26 that there is a meeting from 9:00 to 11:00 for each of March 1 to March 31.

  FIG. 12B shows an example of schedule data in the schedule DB when today's date is February 24, 2009, and the input and recognized character string is “3 days from March 2”. FIG. Also in this example, the time and schedule contents are the same as those in FIG. In this example, in the schedule data 1202, it is stored in the schedule DB 26 that there is a meeting from 9:00 to 11:00 for each of March 2 to March 4.

  FIG. 12C shows an example of schedule data in the schedule DB when today's date is February 24, 2009, and the input and recognized character string is “one week from the next week”. It is. Also in this example, the time and schedule contents are the same as those in FIG. In this example, in the schedule data 1203, it is stored in the schedule DB 26 that there is a meeting from 9:00 to 11:00 for each of March 8 to March 14.

  According to the third embodiment, when the recognized character string includes the period, time, and schedule content, the schedule registration / search unit 24 identifies the date belonging to the period, and identifies the identified date, A time zone based on the time and a record of schedule data including the schedule contents are respectively generated and stored in the schedule DB 26. Therefore, by inputting a period by voice, it is possible to register a schedule for dates belonging to the period. This eliminates the need to repeat the registration every day.

  In addition, according to the third embodiment, the schedule registration / retrieval unit 24 starts the start time indicated by the start time specifying word when the character string related to the time period includes the start time specifying word indicating the start time of the period. The date belonging to the period is specified starting from the time. Therefore, the user can specify a desired period from a desired start time.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
