Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a character input device, a character input method, and a program for simultaneously converting and outputting two or more types of characters by a single input operation.
[0002]
[Prior art]
Japanese is characterized by a one-to-one correspondence between letters and pronunciation.
In a conventional Japanese character input device, for example, a Roman character corresponding to Japanese reading is input via a keyboard or the like, the Roman character is converted to Hiragana and displayed on a monitor screen, and further, the Hiragana is converted to a corresponding Kanji character. Alternatively, a character input method using Roman characters that converts the characters into katakana or the like is common. There is kana input other than Roman character input. In the case of kana input, characters input using a kana key (a kana input mode) are converted to kanji or katakana.
[0003]
When converting Hiragana to Kanji or Katakana, input the Hiragana to be converted and then press the conversion key to display the Kanji or Katakana as conversion result candidates on the monitor screen. It is common to select a specific candidate by inputting the assigned number or selecting it with the up and down keys to determine the converted kanji or katakana.
[0004]
Japanese Patent Application Laid-Open Publication No. H11-163873 proposes a kana-kanji conversion device in which a human writes a document from a word-related knowledge database and appears as a conversion candidate thought in mind. In such a kana-kanji conversion device, the information of the kana is usually discarded when the conversion from the kana to the kanji ends.
[0005]
On the other hand, in a reading device that converts characters used in car navigation and the like into voice and outputs the kanji, various reading methods of kanji may cause erroneous reading. In particular, proper nouns such as place names are often read in a special way, and thus have a feature that the possibility of misreading increases.
[0006]
Patent Literature 2 proposes a method of selectively reading out a section of a paragraph including a header that a user desires to extract in the read text information. From now on, it is conceivable that the reading of characters is written in a header, and this is read out at the time of output, so that reading errors can be eliminated.However, both kanji sentences and reading of those characters are converted to text It is necessary to input the information in advance, and the conventional input device cannot input both at the same time. Therefore, it is necessary to input them separately, which is inconvenient.
[0007]

[Problems to be solved by the invention]
Romaji input and kana key input often correspond one-to-one with reading. In a conventional character input device, when a conversion key is pressed to determine a character from among conversion candidates, character information including information on the original reading is lost or not displayed. For this reason, if an attempt is made to input an input that includes furigana, it is necessary to separately enter the furigana and the corresponding kanji portion, which is very inconvenient and time-consuming for the user.
[0009]
If the phonetic spelling is used, even when encountering unreadable kanji, the possibility of misreading is reduced, which is convenient. Furthermore, it is possible to eliminate a reading error when reading out aloud by a car navigation or a voice browser, which is convenient.
[0010]
The present invention solves the above-mentioned problems, and simultaneously displays a character corresponding to one-to-one reading of a key-input character and a corresponding kanji character, or separately inputs a reading method when voice reading is output. It is an object of the present invention to provide a character input device, a character input method, and a program thereof that are unnecessary.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention converts input characters into characters corresponding one-to-one with how to read hiragana, etc., and simultaneously records or displays the characters after being converted into kanji or the like. , Two types of characters are output by one input operation.
[0012]
More specifically, the character input device of the present invention converts a character input from the input means such that either the input character or a character obtained by converting the character has one-to-one correspondence with how to read the character. Conversion means, character information recording means for recording two or more types of characters of an input character or characters obtained by converting the characters, and simultaneously or sequentially converting the two or more types of characters recorded in the character information recording means. Output means for outputting characters, and character reading means for outputting characters by voice.
[0013]
Further, the character input method of the present invention, when a character input from the input means corresponds one-to-one reading, a first conversion step of converting the input character to Hiragana by the conversion means, A second conversion step of converting the hiragana converted in the first conversion step into a corresponding kanji by the conversion means; and simultaneously or sequentially outputting the hiragana and the kanji converted in the first conversion step and the second conversion step to the output means. And an output step of outputting to
[0014]
Further, in the character input method according to the present invention, when a character input from the input means does not correspond one-to-one to the reading, a first conversion step of converting the input character into a hiragana corresponding to the reading one-to-one. And a second conversion step of converting the hiragana converted in the first conversion step into a corresponding kanji, and simultaneously or sequentially outputting the hiragana and the kanji converted in the first conversion step and the second conversion step to output means. A third conversion step of re-converting the hiragana converted in the first conversion step, and a hiragana converted in the first conversion step or the third conversion step and the hiragana converted in the second conversion step. Output step of simultaneously or sequentially outputting the converted kanji to the output means, wherein the reading means converts the kanji to the first conversion means or the third conversion means. Is characterized by having a reading step reads aloud been hiragana voice.
[0015]
The character input program of the present invention is a program in which the processing in the above character input method is converted into a program code and executed by a computer.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
[First embodiment]
FIG. 1 is a configuration diagram of a character input device according to a first embodiment of the present invention. In the figure, 11 is an input unit such as a keyboard and a mouse, 12 is an information presenting unit such as a personal computer monitor for displaying inputted character information and converted character information, and 13 is an information presenting unit from the control unit. An output unit to be transmitted to the presentation unit, 14 is a control unit that performs various controls, 15 is a character information recording unit that records character information before conversion and character information after conversion, and 16 is a unit that registers a character conversion dictionary and the like. This is a character conversion unit that performs character conversion.
[0017]
In the present embodiment, a case will be described in which an output from the character input device according to the present invention is displayed on the information presenting unit 12 such as a monitor of a personal computer. FIG. 2 is a flowchart showing the flow of the process in that case. Hereinafter, a case in which the character “today” is displayed will be described with reference to FIGS. 1 and 2.
[0018]
The present embodiment is an example in which characters input in Roman characters correspond one-to-one with readings.
A case in which “kyo” is input in Roman characters from the input unit 11 in step S1 of FIG. 2 will be described.
[0019]
In the next step S2, the character conversion unit 16 determines whether the input character has a one-to-one correspondence with the reading. In this case, since the correspondence is one-to-one with the reading ("kyo" and "kyo" correspond one-to-one, that is, step S2: Y), the process proceeds to step S5, where the character is converted by the character conversion unit 16. The converted Roman characters "kyo" are converted to hiragana "kyo". In this example, the conversion to the hiragana as a phonetic character indicating the reading method is recorded in the character conversion unit 16 in advance.
[0020]
Next, in step S6, the converted character "Kyou" is output to the output unit 13, and the output character "Kyou" is sent from the output unit 13 to the information presenting unit 12, and displayed on the screen of the information presenting unit 12. Will be displayed. In step S7, the information is recorded in the character information recording unit 15.
[0021]
In the next step S <b> 8, conversion character candidates are displayed on the information presentation unit 12 from the character conversion unit 16 via the output unit 13. For example, the character conversion dictionary of the character conversion unit 16 includes "today", "strong", "crazy", "co", "mirror", "hibiki", "competition", and "kyo" as characters corresponding to "today". , "Kyo", "Kyoto", "Kai" and the like are registered, and these candidates are displayed on the information presenting unit 12. In the next step S9, a desired character "today" is selected from among these conversion character candidates, and a kanji "today" is selected, determined and converted by pressing a conversion key from the input unit 11 or the like.
[0022]
Here, there may be a case where the user wants to read the kanji character "today" as "Hello". In this case (step S10: Y), a candidate for reading the character "today" is displayed in hiragana for re-conversion (step S11). In the present case, for example, “Today”, “Hello” and the like are displayed. "Hello" is selected, determined, converted (step S12), and recorded in the character information recording unit 12 (step S13). If it is not necessary to perform re-conversion because of the reading of “today” (step S10: N), the process proceeds to step S14.
[0023]
In the present embodiment, a description will be given of a case where the user wants to make “today” without re-conversion. In step S14, the converted character “today” is recorded in the character information recording unit 15.
[0024]
FIG. 3 is a diagram illustrating an example of character data recorded in the input character storage database of the character information recording unit 15 when the same process is repeated to input and convert a Roman character “kyo no tenki”. In the figure, reference numeral 21 denotes input Roman characters, reference numeral 22 denotes phonetic characters (hiragana (how to read)), and reference numeral 23 denotes converted characters.
[0025]
In step S15, the phonetic character (hiragana (how to read)) 22 and the character information of the converted character 23 (hiragana "kyo" and kanji "today") are extracted from the input character storage database of the character information recording unit 15 and the information is obtained. It is displayed in association with the presentation unit 12. In the case of the above example, “Today's weather” and “Today's weather” are displayed as a whole. For example, it can be displayed by spelling furigana "kyo" over kanji "today".
[0026]
As a result, even a difficult kanji can be read, so that a sentence that can be read correctly can be easily input. In addition, in the case of kana input, the procedure for converting from Roman characters to kana is omitted, but otherwise, the input can be performed in the same procedure as described above.
[0027]
[Second embodiment]
FIG. 4 is a configuration diagram of a character input device according to a second embodiment of the present invention. In the figure, 31 is an input unit such as a keyboard and a mouse, 32 is an information presenting unit such as a personal computer monitor for displaying the input character information and the converted character information, and 33 is an information unit from the control unit. An output unit for transmitting to the presentation unit 32 and a character reading unit to be described later, a control unit 34 for performing various controls, a character information recording unit 35 for recording character information before conversion and character information after conversion, and a character information recording unit 36 A character conversion unit which registers a conversion dictionary or the like and performs character conversion, and a character reading unit 37 (similar to a car navigation system or a voice browser) which synthesizes characters by voice and outputs them to a speaker or the like.
[0028]
In the present embodiment, a case will be described in which voice reading of a car navigation system, a voice browser, or the like is performed based on an output from the character input device according to the present invention. FIG. 5 is a flowchart showing the flow of the process in that case. Hereinafter, a case where “9 days” is input will be described with reference to FIGS. 4 and 5.
[0029]
The present embodiment is an example in which characters input in Roman characters do not correspond one-to-one with readings.
A case where “9niti (or 9nichi)” is input from the input unit 31 in step S21 of FIG. 5 will be described.
[0030]
In the next step S22, it is determined whether the characters input by the character conversion unit 36 correspond one-to-one with the reading style. Since there are a plurality of reading candidates such as "kyu" and "ku" for the reading of "9", it cannot be said that there is a one-to-one correspondence with the reading (step S22: N).
[0031]
Then, the process proceeds to step S23, and “Kuni-ichi”, “Kuni-ichi”, etc. are displayed on the information presenting unit 32 as conversion candidates. In the next step 24, a desired reading method (hiragana) is selected, determined, and converted from the reading method candidates displayed in hiragana displayed in step S23. Hereinafter, the case where “9niti” is converted to “kyuni” will be continued. That is, in step S24, "Kyu-nichi" is selected, determined, and converted.
[0032]
In this embodiment as well, as in the first embodiment, the conversion to hiragana as phonograms indicating how to read is recorded in the character conversion unit 36 in advance.
[0033]
Next, in step S26,. The converted hiragana “Kyunichi” representing the reading is output to the output unit 33, and the output character “Kyunichi” is sent from the output unit 33 to the information presentation unit 32, and is displayed on the screen of the information presentation unit 32. Will be displayed. In step S27, the character information is recorded in the character information recording unit 35.
[0034]
In the next step S28, character candidates for conversion are displayed on the information presenting unit 32 from the character converting unit 36 via the output unit 33. In the next step S29, the character to be converted is selected and determined by pressing a conversion key from the input unit 31, and the character conversion unit 36 converts the character to the kanji character "Kyu".
[0035]
Here, there may be a case where the user wants to read “Nine days” as “Here”. Hereinafter, a case where “Nine days” is read as “Here” is described. In this case (step S30: Y), the process proceeds to step S31, in which a plurality of conversion candidates are displayed in hiragana as candidates for reading characters such as "here" or "kyunichi". In the next step S32, the input unit 31 selects, decides, and converts "here" as a candidate for reading the character.
[0036]
In the next step S33, the re-converted hiragana “Kokonoka” is recorded in the character information recording section 35. Further, the character “9th” converted into a kanji in step S34 is recorded in the character information recording unit 35.
[0037]
FIG. 6 is a diagram illustrating an example of character data recorded in the character information recording unit 35 at this time. In the figure, 41 indicates input characters, 42 indicates phonetic characters (Hiragana (reading)), 43 indicates converted characters, and 44 indicates re-converted phonetic characters (Hiragana).
[0038]
In step S35, the hiragana character “Konooka” in the reading style reconverted by the information presenting unit 32 and the character “Kinen” after the kanji conversion are displayed on the information presenting unit 32 via the output unit 33, and It is also output to the reading section 37.
[0039]
If the information presentation unit 32 displays the phonetic word "here" on "9th day", it is possible to read even difficult kanji. In addition, the character reading unit 37 reads out the word "Kono no Kano", which is a hiragana character (spelling), by voice-synthesizing and reading out the word. As a result, it is possible to display a sentence that can correctly read even difficult kanji characters, or to input a character input that can correctly output a voice by a simple operation.
[0040]
It should be noted that “here” or “ninth day” is displayed on the character presentation unit 32 and is not output by the character reading unit 37, or conversely, these are not displayed on the character presentation unit 32 but are displayed only on the character reading unit 37. It goes without saying that any of a method of reading and outputting and a method of outputting to both the character presenting unit 32 and the character reading unit 37 are possible.
[0041]
The processing in the flowcharts of FIGS. 2 and 5 is read into a memory in a character input device via a CD-ROM or an FD (flexible disk) in which program codes are recorded and recorded, or downloaded via the Internet. By reading the data into the memory, it is possible to realize a character input device that automatically performs the above processing.
[0042]
【The invention's effect】
According to the present invention, it is possible to simultaneously output a sentence including kanji and a sentence including only hiragana corresponding to the reading one-to-one by simply inputting a character once, so that a sentence-attached sentence can be easily created. it can. If this is read out by Hiragana by automatic reading-out means using synthesized speech used for car navigation or the like, reading errors can be reduced.
