Description
Technical Field
The present invention relates to a character input method and a character input device, and more particularly, to a character input method and a character input device for inputting polyphones.
Background
At present, when a user wants to input characters, the user can input the characters through a plurality of modes such as a key keyboard, a touch screen, a handwriting input pen, voice and the like, and various electronic devices such as a portable terminal, a vehicle-mounted navigator or a computer recognize the input of the user and prompt at least one character candidate for the user to select the characters the user wants to input. Furthermore, the electronic device may prompt the word containing the identified word candidate for the user to directly select the word containing the word that the user wants to input.
However, the text the user wants to enter may be a polyphonic character having more than two pronunciations. In the related art, when recognizing a character that a user wants to input, an electronic device can present a word including the character, but when the character is a polyphone character, the electronic device presents the user with words corresponding to a plurality of pronunciations mixed together. As a result, it is difficult for the user to quickly select a word desired to be input from the prompted word candidates.
For example, in the conventional technology, when the user inputs a character "heavy" by handwriting, the electronic device presents a plurality of words including "heavy" such as "important", "overlapping", and "important".
However, "heavy" is a polyphone, with two readings, which are oh ch and zh. In the words mentioned above, the sounds of "heavy" are also different, namely "heavy (zh oa)," (zh oa) point "," heavy (ch oa) and "(zh oa) sight", etc. In the prior art, as described above, the words including different pronunciations of polyphones are mixed and displayed together, and it is difficult for a user to quickly select a word (such as "touch up").
Particularly, in the prior art, words including different pronunciations of polyphones are mixed and displayed together, and when there are many word candidates, the word candidate which the user wants to input may not be displayed in the display area, and the user needs to perform a page turning operation, which greatly increases the operation amount of the user and the processing amount of the electronic device.
Disclosure of Invention
In view of the above-described problems of the prior art, it is an object of the present invention to provide a character input method and a character input device that enable a user to quickly find and select a word that the user desires to input when the character input by the user is a polyphonic character.
The character input method of the embodiment of the invention is used for inputting characters, and is characterized by comprising the following steps: an input reception step of receiving an input character; a polyphone information acquisition step of acquiring polyphone information, the polyphone information including: the method comprises the following steps that a plurality of pronunciations of polyphone characters are provided, and corresponding relations between words containing the polyphone characters and the pronunciations in the polyphone characters are provided; a polyphone determination step of determining whether the character received by the input reception step is a polyphone based on the polyphone information acquired by the polyphone information acquisition step; and a display control step of controlling, when the polyphone character determination step determines that the received character is a polyphone character, to display a word including the pronunciation for the pronunciation of the character based on the polyphone information.
Therefore, when the characters input by the user are polyphones, the user can quickly find and select the words desired to be input, the operation amount of the user is reduced, and the character input efficiency is improved.
In the above-described character input method, when the polyphone determination step determines that the received character is a polyphone, the display control step may control to display each of a plurality of pronunciations included in the character, and the character input method may further include a selection reception step of receiving a selection operation performed on any one of the plurality of pronunciations included in the displayed character, and when the selection operation performed on any one of the pronunciations is received by the selection reception step, the display control step may control to display a word including the selected pronunciations as a candidate so that the user selects a word to be input from among words including the selected pronunciations.
This makes it possible to suppress the number of contents to be simultaneously displayed, and is particularly suitable for a case where the size of the display area is limited, such as a smart phone, a smart watch, and a car navigation device.
In the above-described character input method, when the polyphone determination step determines that the received character is a polyphone, the display control step may control to display each of the plurality of pronunciations of the character and display the words including the pronunciations as candidates for the pronunciations so that the user selects the word to be input from the words including each pronunciation.
Therefore, the user can clearly master the corresponding relation between each pronunciation of the polyphone and the words containing the pronunciation, the user can more quickly find and select the words which the user wants to input, and the user experience is further improved.
In the above-described character input method, the polyphonic information acquisition step may acquire a plurality of pronunciations of a polyphonic character from a polyphonic character database, and acquire, as the polyphonic information, a correspondence between a word including the polyphonic character and each of the pronunciations from a polyphonic character-word database.
Thus, even if data communication is not performed with an external server or a removable storage medium is not connected, when the character input by the user is a polyphone character, the user can quickly find and select the word desired to be input, the operation amount of the user can be reduced, and the character input efficiency can be improved.
In the above-described character input method, the character input method may further include a language type determination step of determining a language type of the character accepted by the input acceptance step, and the polyphonic character information acquisition step may acquire, from the polyphonic character database of the language type, a plurality of pronunciations of the polyphonic character of the language type, based on the language type determined by the language type determination step, and acquire, from the polyphonic character language database of the language type, a correspondence between a word including the polyphonic character of the language type and each of the pronunciations of the plurality of pronunciations, as the polyphonic character information of the language type.
Therefore, under the condition of multi-language input, the language can be automatically judged, and a user can quickly find and select the words which the user wants to input aiming at polyphones in the language.
In the above-described character input method, the language type determination step may determine at least whether the language type of the character received by the input reception step is one of a chinese language and a japanese language, the polyphonic character information acquisition step and the polyphonic character determination step may be executed when the language type determination step determines that the language type of the character received by the input reception step is one of a chinese language and a japanese language, and the polyphonic character information acquisition step and the polyphonic character determination step may not be executed when the language type determination step determines that the language type of the character received by the input reception step is not one of a chinese language and a japanese language.
Thus, when the received characters are in a language other than the languages such as chinese and japanese in which polyphones are not present, the amount of useless processing can be reduced and the processing speed can be increased.
An embodiment of the present invention provides a character input device for inputting characters, including: a receiving unit for receiving an input character; a polyphone information acquisition unit that acquires polyphone information, the polyphone information including: the method comprises the following steps that a plurality of pronunciations of polyphone characters are provided, and corresponding relations between words containing the polyphone characters and the pronunciations in the polyphone characters are provided; a polyphone determination unit configured to determine whether or not the character received by the reception unit is a polyphone based on the polyphone information acquired by the polyphone information acquisition unit; and a display control unit that controls, when the polyphone character determination unit determines that the received character is a polyphone character, to display a word including the pronunciation for each of the pronunciations of the character based on the polyphone information.

Detailed Description
The present invention will be described in more detail below with reference to the accompanying drawings, embodiments, and specific examples. The following description is only an example for the convenience of understanding the present invention and is not intended to limit the scope of the present invention. In the embodiments, the components of the apparatus may be changed, deleted or added according to the actual situation, and the steps of the method may be changed, deleted, added or changed in order according to the actual situation. In the drawings, the arrangement, size, direction, and the like of the display are merely illustrative and may be changed according to the actual situation.
(first embodiment)
The first embodiment of the present invention will be specifically explained. First, the character input device 10 according to the first embodiment of the present invention will be described. The character input device 10 is applicable to various portable terminals such as a smart phone, a tablet computer, and a smart watch, and various electronic devices such as a car navigation system and a computer, for example, and allows a user to input characters. Fig. 1 is a block diagram showing a configuration of a character input device 10 according to a first embodiment of the present invention. As shown in fig. 1, the character input device 10 includes a reception unit 11, a polyphonic information acquisition unit 12, a polyphonic determination unit 13, and a display control unit 14. The character input device 10 and the server 20 can perform data communication via a wired or wireless network, for example, and acquire polyphonic information from a database included in the server 20. Here, the character input device 10 and the server 20 may constitute a character input system. Hereinafter, each component of the character input device 10 will be described in detail.
The reception unit 11 is for receiving characters to be input, and may be realized by a touch panel, a handwriting input pen, a key pad, a microphone, or the like. For example, the reception unit 11 may be used for a user to input handwriting input through a touch panel, a handwriting pen, or the like, and recognize the input as a character such as a chinese character through a character recognition technique. Alternatively, the acceptance unit 11 may be used to input pinyin to the user through a keypad or the like and convert the pinyin to characters such as chinese characters. Alternatively, the reception unit 11 may be used for a user to input a voice by a microphone or the like and convert the voice into a character such as a chinese character by a voice recognition technique. The receiving unit 11 may use the closest recognized/converted character as the received character, or may use a plurality of recognized/converted characters that are relatively close as candidates for selection by the user and use the character selected by the user as the received character. The receiving unit 11 is not limited to this, and characters such as chinese characters may be input by a copy/paste operation by a user. The receiving unit 11 may be used for the user to input characters other than kanji characters.
The polyphone information acquisition unit 12 acquires polyphone information including: the polyphones have a plurality of pronunciations and a correspondence between the words containing the polyphones and each of the pronunciations. As an example of a polyphone character having multiple readings, "heavily" is a polyphone character and has two readings, ch pu' ing and zh oa. As an example of a correspondence between a word comprising the polyphone and each pronunciation, the word "important" corresponds to the pronunciation "zh oa ng", and the word "coincident" corresponds to the pronunciation "(ch actuating ng)".
As shown in fig. 1, the polyphonic information acquisition unit 12 may acquire polyphonic information from a database provided in the server 20, for example, by performing data communication with the server 20, acquire a plurality of pronunciations of the polyphonic character from a polyphonic database provided in the server 20, and acquire a correspondence relationship between a word including the polyphonic character and each of the pronunciations from a polyphonic word database provided in the server 20. The polyphonic information obtaining unit 12 may obtain polyphonic information, and the obtaining method is not limited to this, and polyphonic information may be obtained from a database included in the character input device 10, or may be obtained from a database stored in a removable storage medium such as a flash memory through a read interface. The polyphonic information acquisition unit 12 may be realized by a processor included in the character input device 10 executing a character input program stored in a memory, or may be realized by a dedicated circuit.
The polyphone determination unit 13 determines whether or not the character received by the reception unit 11 is a polyphone based on the polyphone information acquired by the polyphone information acquisition unit 12. For example, the polyphone determination unit 13 searches for the character received by the reception unit 11 among polyphones having a plurality of pronunciations indicated by the polyphone information. When the received character is searched for in the polyphone information, it is determined that the received character is a polyphone. When the received character is not searched in the polyphone information, the received character is determined not to be a polyphone. The polyphonic determination unit 13 may be realized by a processor included in the character input device 10 executing a character input program stored in a memory, or may be realized by a dedicated circuit.
When the polyphone determination unit 13 determines that the received character is a polyphone character, the display control unit 14 controls the display of a word including the pronunciation of the character based on the polyphone information. The display control unit 14 may control a display (not shown) provided in the character input device 10 itself, or may output a display control signal via a display output interface to control an external display (e.g., an in-vehicle HUD display). The display control unit 14 may be realized by a processor included in the character input device 10 executing a character input program stored in a memory, or may be realized by a dedicated circuit. The manner in which a word including a reading is displayed for each reading of a polyphone is not limited as long as the user can distinguish the corresponding word for each reading of the polyphone, and several specific examples will be described below in conjunction with a character input method.
The following describes a character input method executed by the character input device 10 according to the present embodiment. Fig. 2 is a flowchart of an example of a character input method according to the first embodiment of the present invention. The flow of fig. 2 may be executed in a state where the character input device 10 can accept user input, for example. The following step S101 corresponds to an input reception step, step S102 corresponds to a polyphone information acquisition step, step S103 corresponds to a polyphone determination step, and steps S104 and S105 correspond to a display control step.
In step S101, the reception unit 11 receives the inputted character, for example, a character handwritten by the user through a touch panel. Fig. 3 is a schematic diagram showing an example of the first embodiment of the present invention. As shown in fig. 3, the user is assumed to perform handwriting input in the handwriting area, and the reception unit 11 presents a plurality of character candidates based on the handwriting input by the user. Here, it is assumed that the user selects "heavy" among the character candidates presented by the reception unit 11, and the reception unit 11 receives an input of a chinese character "heavy". In the display example described later, presentation and selection of character candidates are omitted.
In step S102, the polyphonic information obtaining part 12 obtains polyphonic information that includes two readings ch that are "heavy" as polyphonic characters, and an oa and zh, and a correspondence between words and expressions that include "heavy" and the respective readings, for example, the word "important" corresponds to the reading "zh, the word" overlapping "corresponds to the reading" ch an "and so on.
In step S103, the polyphone determination unit 13 determines whether or not the character received in step S101 is a polyphone based on the polyphone information acquired in step S102. Step S104 is executed when it is determined to be a polyphone, and step S105 is executed when it is determined not to be a polyphone. Here, since the polyphone information indicates that "repeat" is a polyphone, it is determined that the character received in step S101 is a polyphone, and step S104 is executed.
In step S104, the display control unit 14 controls the display of the word including the pronunciation for each pronunciation of the character based on the polyphonic information. As shown in fig. 3, the display control unit 14 controls: the words "coincide", "overlap", "repeat", "come again", "go again" etc. which comprise the pronunciation are displayed by the pronunciation "ch huang", and the words "important", "emphasized", "center of gravity", "weight", etc. which comprise the pronunciation are displayed by the pronunciation "zh. Further, the display control unit 14 may be controlled such that a page turning mark (for example, "ˇ" shown in fig. 3) is displayed after a word including each reading, and if the receiving unit 11 receives a selection of a page turning mark corresponding to a word including a certain reading by the user, the display control unit 14 displays more words including the reading.
When the received character is not a polyphonic character, the display control unit 14 displays a word including the character in step S105. In the case where the received character is a character other than a kanji character (a letter, a numeral, a character, etc.), the display control unit 14 may directly display the character.
However, step S102 (polyphonic information acquisition step) may be executed before step S101 (input reception step), that is, polyphonic information may be acquired in advance. In addition, step S102 (polyphonic information acquisition step) may be separately executed, and information indicating a polyphonic character having a plurality of voices may be acquired, and after it is determined based on the information that the received character is a polyphonic character in step S103, the correspondence relationship between the word including each pronunciation of the polyphonic character and each pronunciation may be acquired.
In order to facilitate understanding of the technical effects of the present embodiment, a prior art display example is illustrated as a comparative example. Fig. 4 is a schematic diagram illustrating a display example of the related art as a comparison. As shown in fig. 4, in the prior art, for polyphones, as with other chinese characters, a word including the recognized character candidates is presented. In this case, the words ("important", "center of gravity", "weight", etc.) including the pronunciation "zh oa ng" and the words ("overlap", "repeat", "come over", "go over", etc.) including the pronunciation "ch oa ng" are displayed together, from which it is difficult for the user to quickly select the word he wants to input.
For example, according to the above-described explicit example of the prior art, when the user wishes to select "reset (ch you ng) close", which is mixed in the words comprising the other readings "zh you ng", the user has to select the 3 rd word to the right in order to select "overlap", which is difficult to find and select quickly.
Or, when the user wishes to select the "heavy (zh oa) heart", since the word comprising the sound "zh oa" and the words comprising the other sound "ch actuating ng" are displayed mixed and mixed, the "center of gravity" cannot be displayed in the display area, but the user is required to perform a page turning operation by selecting a page turning mark, and the "center of gravity" can be selected in the second page, which is more difficult to find and select quickly.
On the other hand, in the display of the present embodiment, for example, as shown in fig. 3, words including different pronunciations of polyphones are displayed separately, and the user can quickly select a word to be input based on the different pronunciations of the polyphones. For example, when the user wishes to select "Redo (ch xi ng) and" Redo (ch xi ng) "separately, since the word is displayed in the first row by its pronunciation (ch xi ng), the user can select" coincidence "by just selecting the 1 st word, and can quickly find and select.
In particular, if the user wishes to select the "heavy (zh oa) center", the user can select the "center of gravity" merely by selecting the 4 th word to the right, since this word is displayed separately in the second row by its reading (zh oa), and can quickly find and select this without having to perform a page-turning operation as in the prior art.
According to the character input device 10 and the character input method of the present embodiment, when the character input by the user is a polyphone character, the user can quickly find and select the word desired to be input, the amount of operation by the user can be reduced, and the efficiency of character input can be improved.
In the present embodiment, when the polyphone determination unit 13 determines that the received character is a polyphone, the display control unit 14 may also give priority to the plurality of pronunciations included in the polyphone, and control the display unit to display a word including a pronunciation with a high priority and a word including a pronunciation with a low priority in different display modes based on the priorities of the plurality of pronunciations.
For example, the polyphonic character determination unit 13 may give priority to the pinyin in accordance with the order of the pinyin between the plurality of pronunciations, and the display control unit 14 may control to display a word including a pronunciation with a high priority in the front (for example, displayed in the first line) and a word including a pronunciation with a low priority in the rear (for example, displayed in the second line). Therefore, the method and the device can better conform to the habit of the user, and enable the user to find and select the words which the user wants to input more quickly.
For example, the polyphonic character determination unit 13 may give priority to words including high-priority pronunciations in descending order of the number or frequency of use of the words including the respective pronunciations, and the display control unit 14 may control to display words including high-priority pronunciations in the front (for example, in the first line) and display words including low-priority pronunciations in the rear (for example, in the second line). Thus, the words of pronunciation with a large number of words or a large frequency of use can be displayed in front, the operation amount of the user is further reduced, and the efficiency of character input is improved.
For example, the polyphonic character determination unit 13 may give priority to words including the pronunciations in descending order of the number or frequency of use of the words, and the display control unit 14 may control to allocate a larger display area to words including a pronunciation with a higher priority so as to display more words and allocate a smaller display area to words including a pronunciation with a lower priority. Thus, the number of words or words of pronunciation having a high frequency of use can be displayed in a larger display area, and the amount of user operations can be further reduced, thereby improving the efficiency of character input.
In addition, the display control unit 14 may adopt different display fonts, display sizes, display colors, and the like for words including a high-priority pronunciation and words including a low-priority pronunciation according to the priority of each pronunciation.
(modification 1)
Modification 1 of the present embodiment will be described below. In modification 1, the structure of the character input device 10 is the same as that of the first embodiment, and therefore, the description thereof is omitted, and the method of character input performed by the character input device 10 is different from that of the first embodiment, and the following description focuses on the differences.
Fig. 5 is a flowchart of a character input method according to modification 1 of the first embodiment of the present invention. In fig. 5, steps S201 to S203, and S207 are the same as steps S101 to S103, and S105 of fig. 2, respectively, and are not described again. Steps S204, S206, and S207 correspond to the display control step, and step S205 corresponds to the selection acceptance step. The following is a detailed description.
When the polyphone determination unit 13 determines in step S203 that the received character is a polyphone, step S204 is executed, and the display control unit 14 controls to display each of the plurality of pronunciations included in the character. Fig. 6 is a schematic diagram showing a display example of modification 1 of the first embodiment of the present invention. As shown in the left-hand part of fig. 6, the display control unit 14 controls the display of the respective readings (ch, oa and zh, oa) of the accepted polyphone (e.g. "heavy") for selection by the user.
In step S205, the receiving unit 11 receives a selection operation for any one of the plurality of readings of the displayed character. If the accepting unit 11 has not accepted the selection operation, the process returns to step S205. If the receiving unit 11 receives a selection operation for any one of the readings (for example, the user selects the desired pronunciation ch, rounding ng), step S206 is executed.
In step S206, the display control unit 14 controls the user to select a word to be input from the words including the selected pronunciation so that the words including the selected pronunciation are displayed as candidates. As shown in the right part of fig. 6, after accepting the selection operation of the user for the pronunciation ch shake, the display control unit 14 controls to display the word including the pronunciation ch shake as a candidate.
According to this modification, the word including the pronunciation is displayed in accordance with the selection of a certain pronunciation of the polyphonic character by the user, so that the user can quickly find and select the word desired to be input, the amount of operation by the user can be reduced, and the efficiency of character input can be improved. In addition, the present modification can suppress the number of contents to be simultaneously displayed, and is particularly suitable for a case where the size of the display area is limited, such as a smart phone, a smart watch, and a car navigation device.
(modification 2)
Modification 2 of the present embodiment will be described below. In modification 2, the structure of the character input device 10 is the same as that of the first embodiment, and therefore, the description thereof is omitted, and the method of character input performed by the character input device 10 is different from that of the first embodiment, and the following description focuses on the differences.
Fig. 7 is a flowchart of a character input method according to variation 2 of the first embodiment of the present invention. In fig. 7, steps S301 to S303 and S305 are the same as steps S101 to S103 and S105 of fig. 2, respectively, and are not repeated herein. Steps S304 and S305 correspond to a display control step. The following is a detailed description.
When the polyphone determination unit 13 determines in step S303 that the received character is a polyphone, step S304 is performed, and the display control unit 14 controls to display each of the plurality of pronunciations of the character and to display the words including the pronunciations for each pronunciation so that the user selects a word to be input from the words including each pronunciation. Fig. 8 is a schematic diagram showing a display example of modification 2 of the first embodiment of the present invention. As shown in fig. 8, the display control unit 14 controls the display of the respective readings (ch, oa and zh, oa) of the accepted polyphone (for example, "heavy") and the sound display of the words containing the readings as candidates.
According to the present modification, by displaying each pronunciation of a polyphonic character and displaying the word including the pronunciation in accordance with the pronunciation, the user can quickly find and select the word desired to be input, the amount of operation by the user can be reduced, and the efficiency of character input can be improved. In addition, the user can clearly master the corresponding relation between each pronunciation of the polyphone and the words containing the pronunciation, the user can more quickly find and select the words which the user wants to input, and the user experience is further improved.
In the present embodiment, the display mode of modification 1 and the display mode of modification 2 may be switched. For example, depending on the size of the display area, the display mode is switched to the display mode of modification 1 when the display area is smaller than a predetermined threshold value, and the display mode is switched to the display mode of modification 2 when the display area is equal to or larger than the predetermined threshold value.

Alternatively, depending on the number of words including a certain polyphone, the display mode of modification 1 is switched when the number of words is equal to or greater than a predetermined threshold (e.g., 10), and the display mode of modification 2 is switched when the number of words is less than a predetermined threshold (e.g., 10).
(second embodiment)
The second embodiment of the present invention will be specifically explained. In the present embodiment, in addition to the first embodiment or its modifications, the character input device 10B is additionally provided with a storage unit 15 for storing polyphonic information. The following description focuses on differences of the present embodiment with respect to the first embodiment and its modifications, and the same or similar contents as or to the first embodiment and its modifications are omitted in the present embodiment.
Fig. 9 is a block diagram showing a configuration of a character input device 10B according to a second embodiment of the present invention. As shown in fig. 9, the character input device 10B includes a storage unit 15, and is configured by a nonvolatile storage medium such as a hard disk drive or a flash memory. The storage section 15 stores a polyphonic database 151 and a polyphonic word database 152. The following is a detailed description.
Fig. 10 is a table showing the multi-tone database 151 according to the second embodiment of the present invention. In the polyphone database 151, a plurality of pronunciations of polyphones are stored. As shown in fig. 10, the polyphone database 151 stores a plurality of polyphones in a first column, a first reading of each polyphone in a second column, a second reading of each polyphone in a third column, and a third reading of each polyphone in a fourth column, which are sequentially followed. For example, the polyphone "double" is stored in the first row of the polyphone database 151, which has a first sound ch, rounding and a second sound zh, oa. However, the polyphone database 151 may store only a part of polyphones as needed, instead of storing all polyphones.
FIG. 11 is a table showing a multivocal word database 152 according to a second embodiment of the present invention. In the polyphonic word and phrase database 152, correspondence between a word including a polyphonic word and each of the plurality of pronunciations of the polyphonic word is stored. As shown in fig. 11, the polyphonic words database 152 stores a plurality of polyphonic words in a first column, words including the polyphonic words in a second column, and pronunciations of the polyphonic words corresponding to the words in the second column in a third column. For example, the first row of the polyphonic word and phrase database 152 stores the word "important" comprising the polyphonic word "heavy", the corresponding sound is zh oa, the second row stores the word "coincident" comprising the polyphonic word "heavy", the corresponding sound is ch os, the third row stores the word "weight" comprising the polyphonic word "heavy", and the corresponding sound is zh oa. The polyphonic word and phrase database 152 may store only a part of polyphonic words and a part of phrases thereof as needed, instead of storing all polyphonic words and all phrases thereof.
Returning to fig. 9, the polyphone information acquisition unit 12 acquires a plurality of pronunciations of a polyphone from the polyphone database 151, and acquires a correspondence relationship between a word including the polyphone and each of the pronunciations as polyphone information from the polyphone word database 152.
According to the present embodiment, the character input device 10B includes the polyphonic database 151 and the polyphonic phrase database 152, and enables the user to quickly find and select a word desired to be input when the character input by the user is a polyphonic character without data communication with an external server or without connecting a removable storage medium, thereby reducing the amount of operation by the user and improving the efficiency of character input.
(third embodiment)
The third embodiment of the present invention will be specifically explained. In the first and second embodiments and their modifications, the case where the technique is applied to a single language (for example, chinese language) has been described. However, polyphones exist not only in chinese, but also in other languages such as japanese. The present embodiment is further applicable to a case of multiple languages in addition to the first and second embodiments or the respective modifications thereof. The following description focuses on differences of the present embodiment with respect to the first and second embodiments and their modifications, and the same or similar contents to those of the first and second embodiments and their modifications are omitted in the present embodiment.
First, the character input device 10C of the present embodiment will be described. Fig. 12 is a block diagram showing a structure of a character input device 10C according to a third embodiment of the present invention. As shown in fig. 12, the storage unit 15 stores a chinese polyphone database 1511, a chinese polyphone word database 1521, a japanese polyphone database 1512, and a japanese polyphone word database 1522. The databases may be stored in an external server 20 or a removable storage medium. In addition, a polyphonic database and a polyphonic word database of other languages may also be stored.
As shown in fig. 12, the character input device 10C of the present embodiment further includes a language type determination unit 16 for determining the language type of the character received by the reception unit 11. For example, the language type determination unit 16 may determine the language corresponding to the received character itself (for example, the code corresponding to the character), or may determine the language of the received character based on the language of the input method of the character input device 10C, the language corresponding to the region where the character input device 10C is located, personal information or history information of the user using the character input device 10C, or the like.
The polyphonic information acquisition unit 12 acquires, from the polyphonic database of the language type, a plurality of pronunciations of the polyphonic character of the language type based on the language type determined by the language type determination unit 16, and acquires, from the polyphonic word language database of the language type, a correspondence between a word including the polyphonic character of the language type and each of the pronunciations as polyphonic information of the language type.
The following describes a character input method executed by the character input device 10C according to the present embodiment. Fig. 13 is a flowchart of an example of a character input method according to a third embodiment of the present invention. In fig. 13, step S401 is the same as step S101 of fig. 2, and is not described herein again. Step S402 corresponds to a language type determination step, step S403 corresponds to a polyphone information acquisition step, step S404 corresponds to a polyphone determination step, and steps S405 to S406 correspond to a display control step.
In step S402, the language type determination unit 16 determines the language type of the character received in step S401. For example, when the character "after" is received in step S401, the language type determination unit 16 determines that the language type of the character is Japanese.
In step S403, the polyphonic information acquisition unit 12 acquires, from the polyphonic database of the language type, a plurality of pronunciations of the polyphonic character of the language type based on the language type determined in step S402, and acquires, from the polyphonic word database of the language type, a correspondence between each pronunciation and a word including the polyphonic character of the language type as polyphonic information of the language type. Here, the polyphonic information acquisition unit 12 acquires a plurality of pronunciations of polyphonic characters in japanese from the japanese polyphonic database 1512, and acquires the correspondence between the words including the polyphonic characters in japanese and the respective pronunciations from the japanese polyphonic word database 1522.
In step S404, the polyphone determination unit 13 determines whether or not the received character is a polyphone. Here, the polyphone determination unit 13 determines that the received character "" is a polyphone in japanese "" based on the japanese polyphone database 1512, and executes step S405.
In step S405, the display control unit 14 controls to display a word including the pronunciation for each pronunciation of the polyphonic character. Several examples of the display are described in detail below.
Fig. 14 is a schematic diagram showing an example of the third embodiment of the present invention, and corresponds to modification 1 of the first embodiment of the present invention. As shown in fig. 14, the display control unit 14 controls to display japanese kanji "after" and a plurality of pronunciations "ゴ (go), アト (ato), ノチ (nochi), シリ (shiri)" thereof for the user to select. After accepting a user selection of, for example, pronunciation "アト (ato)," the words including the selected pronunciation "アト (ato)" are displayed as candidates so that the user selects a word to be input from the words including the pronunciation.
Fig. 15 is a schematic diagram showing another example of the third embodiment of the present invention, and corresponds to modification 2 of the first embodiment of the present invention. As shown in fig. 15, the display control unit 14 controls to display japanese kanji "after" and a plurality of pronunciations "ゴ (go), アト (ato), ノチ (nochi), シリ (shiri)" thereof, and to display words including the pronunciations as candidates for each pronunciation so that the user selects a word to be input from the words including each pronunciation.
In order to facilitate understanding of the technical effects of the present embodiment, a prior art display example is illustrated as a comparative example. Fig. 16 is a schematic diagram illustrating a display example of the related art as a comparison. As shown in fig. 16, in the related art, for polyphones in japanese, as with other kanji in japanese, words including recognized character candidates are presented, and words including respective pronunciations are displayed mixed together, and it is difficult for a user to quickly select a word that the user wants to input.
According to the character input device 10C and the character input method thereof of the present embodiment, in the case of multi-language input, it is possible to automatically determine the language type and quickly find and select a word that the user desires to input for polyphonic characters in the language type.
One specific example of the present embodiment is described below. In this specific example, the configuration of the character input device 10C is the same as that of the third embodiment, and therefore, the description thereof is omitted, and the method of character input performed by the character input device 10C is different from that of the third embodiment, and the following description focuses on the difference.
Fig. 17 is a flowchart of another example of the character input method according to the third embodiment of the present invention. In fig. 17, step S501 is the same as step S401 of fig. 13, and steps S505 to S507 are the same as steps S404 to S406 of fig. 13, which are not repeated herein. Step S502 corresponds to a language type determination step, and steps S503 and S504 correspond to a polyphonic information acquisition step.
In step S502, the language type determination unit 16 determines whether the language type of the character received in step S501 is one of chinese and japanese. When the received character is determined to be the chinese language, the polyphonic information acquisition unit 12 acquires polyphonic information of the chinese language from the chinese polyphonic database 1511 and the chinese polyphonic phrase database 1521 by executing step S503. When it is determined that the received character is japanese, the polyphonic information acquisition unit 12 acquires polyphonic information of japanese from the japanese polyphonic database 1512 and the japanese polyphonic word database 1522 in step S504. If it is determined that the language of the received character is not either chinese or japanese, for example, if the received character is english, the step S507 is directly executed without executing the polyphonic information acquisition step and the polyphonic determination step.
In addition, when the present invention is applied to other polyphonic languages including polyphonic characters other than chinese and japanese languages, it is also possible to determine whether or not the language of the received character is the other polyphonic language in step S502, and in the case of the other polyphonic language, the polyphonic information acquiring unit 12 acquires polyphonic information of the other polyphonic language.
According to the character input device 10C and the character input method of the present specific example, when the received character is a language other than the languages such as chinese and japanese in which a polyphone does not exist, it is possible to reduce the amount of useless processing and increase the processing speed without acquiring polyphone information and determining whether the character is a polyphone.
However, the steps included in the character input method according to each of the above embodiments of the present invention may be implemented as steps included in a character input program or as a storage medium on which the character input program is recorded, and the same technical effects can be obtained.
