Abstract

PURPOSE:To efficiently input four tones by providing a Chinese four tones identifying device, picking-up a KANJI (Chinese character) to be determined by an inputted Chinese phonogram string and the identified result of the Chinese four tones identifying device from a conversion dictionary and displaying the KANJI in a display part. CONSTITUTION:For example, when it is desired to input the KANJI pronouncing 'mei,' the 'MEI' is inputted from a keyboard 1 and the sound of the 'mei' is inputted from a microphone 2. When the sound of the 'mei' is inputted, a Chinese four tones identifying device 3 identifies that the 'mei' is the third tone. Then, the identified result is sent to a display control part 5. When the pin-in of the 'MEI' is inputted, a KANJI conversion processing part 4 immediate ly sends the 'MEI' to the display control part 5. When the 'MEI' and identified result (third tone) of the four tones are received, the display control part 5 displays the character strings of the 'MEI' and the 'third tone' on the screen of a display part 6. Thus, the input of the four tones can be efficiently executed.

Description

[Detailed Description of the Invention] [Summary] Regarding the improvement of a Chinese input method that displays on a display a Chinese kanji character corresponding to a combination of a Chinese phonetic character string of a Chinese kanji character and a four-tone tone of the Chinese kanji character, In this type of Chinese input method, with the aim of efficiently inputting the four tones, we developed a Chinese four-tone identification device to identify which of the four tones the sounds of Chinese characters belong to. The Chinese character string determined by the Chinese phonetic character string input from the keyboard and the identification result of the Chinese four-tone recognition device is extracted from the conversion dictionary and displayed on the display unit.

[Industrial application field]

The present invention relates to an improvement of a Chinese input method that displays on a display a Chinese kanji character corresponding to a combination of a Chinese phonetic character string of a Chinese kanji character and four tones of the Chinese kanji character. [Prior Art] In recent years, along with computerization in the information processing field, there has been an increasing demand for kanji input/output processing based on a man-machine interface in areas where kanji are cultured.

Two well-known Chinese input methods are one in which only phonetic character strings are input, and the other in which phonetic character strings and symbols representing the four tones are input from a keyboard.

[Problem to be solved by the invention]

As mentioned above, the Chinese input method is: ■ A method in which only Chinese phonetic strings are input from the keyboard.

■ A method of inputting both Chinese phonetic strings and symbols representing the four tones of Chinese from the keyboard.

However, the method (■) does not take into account the four tones, so it has the disadvantage that there are too many kanji candidates with the same reading, and it takes time to find the desired kanji. There is.

Method (2) can limit the number of candidates by inputting the phonetic string and the four tones at the same time.
Since the four tones must be input from the keyboard, it has the disadvantage that kanji input cannot be performed efficiently.

The present invention was created in view of this point, and is a method for inputting four tones in a Chinese input method in which Chinese characters corresponding to a combination of a Chinese phonetic character string and four tones are displayed on a display unit. The aim is to make it possible to do this efficiently.

[Means to solve the problem]

FIG. 1 is a diagram explaining the principle of the present invention. In the same figure, 1
is a keyboard, 2 is a microphone, 3 is a Chinese four-tone recognition device, 4 is a Chinese character conversion processing unit, 5 is a display control unit, 6
indicates the display section. The Chinese four-tone recognition device 3 selects the Chinese kanji voice input from the microphone 2 as the first voice. Second voice, third voice. This is to identify which of the fourth tones it corresponds to. The identification results of the Chinese four-tone identification device 3 are sent to the Chinese-kanji conversion processing section 4 and the display control section 5. When a Chinese phonetic character string (pinyin) is sent from the keyboard 1, the Chinese-kanji conversion processing unit 4 sends this Chinese phonetic character string to the display control unit 5, and then converts the Chinese phonetic character string to the display control unit 5. The Chinese kanji determined by the combination of the sound character string and the identification result of the Chinese four-tone identification device 3 is retrieved from the bin-in four-tone one-kanji conversion dictionary (not shown), and the retrieved Chinese kanji is sent to the display control unit 5. .

The display control unit 5 receives the sent Chinese phonetic character string. The identification results of the Chinese four-tone identification device 3 and the Chinese characters are displayed on the display unit 6.

[Effect]

For example, if you want to input the Chinese character ``美'', input rME IJ from the keyboard 1 and input the voice ``美'' from the microphone 2.

When “美” is input by voice, the Chinese four-tone recognition device 3
It is identified that "bi" is the third voice, and the identification result is sent to the display control unit 5. The Chinese kanji conversion processing unit 4 is rMEIJ
When the Pinyin is input, rMEIJ is immediately sent to the display control unit 5. When the display control unit 5 receives rMEIJ and the four-tone identification result (third voice), it displays rME t J and the character string “third voice” on the screen of the display unit 6.

The operator presses the conversion key on the keyboard 1 after checking the display of rMEIJ and "third voice" and confirming that they are correct. When the conversion key is pressed, the Chinese kanji conversion processing unit 4 converts the Chinese kanji (bi, mai...) determined by rMEIJ and the four-tone identification result (third tone) into Pinyin four-tone one kanji. It is taken out from the dictionary and sent to the display control section 5.

The display control unit 5 receives the sent ``bi'', ``mai'', etc. ...
is displayed on the screen of the display section 6.

〔Example〕

Figure 2 is a block diagram showing an example of the structure of the Chinese-Kanji conversion processing section, and Figure 3 is a diagram showing part of the Pinyin four-tone one-Kanji conversion dictionary. In the figure, 4l is an input control section, 42 is a Pinyin conversion control section, 43 is a Pinyin four-tone one-kanji conversion dictionary, 44 is a code/pattern conversion dictionary, 45 is a code/pattern conversion control section, 46 is an output control section, Reference numeral 401 indicates input information, 402 indicates binyin and four-tone information, 403 indicates a Kanji code, and 404 indicates a Kanji pattern.

Upon receiving the four-tone information and pinyin, the input control section 41 sends the pinyin to the output control section 46 and sends the pinyin and the four-tone information to the pinyin conversion control section 42 . The Pinyin conversion control unit 42 extracts the Chinese Kanji code corresponding to the combination of Pinyin and four-tone information from the Pinyin four-tone one-kanji conversion dictionary 43 and sends the extracted Chinese Kanji code to the code/pattern conversion control unit 45 .

As shown in Figure 3, Pinyin four tones one kanji conversion dictionary 43
has multiple lines, and each line is filled with pinyin, four tones, and Chinese characters.

For example, in the row where pinyin is rMFIJ and four tones is "3", the Chinese characters "bi", "mai", . . . are written.

The code/pattern conversion control unit 45 converts the Chinese kanji pattern corresponding to the sent Chinese kanji code into a code/pattern conversion control unit 45.
The Chinese character pattern is extracted from the pattern conversion dictionary 44 and sent to the output control section 46. Output control section 46
sends the pinyin sent from the input control section 41 and the Chinese Kanji pattern sent from the code/pattern conversion control section 45 to the display control section 5 (not shown).

FIG. 4 is a functional block diagram of an example of the structure of a Chinese four-tone recognition device. In the figure, 31 is an A/D conversion section, 32 is a voice analysis section, 33 is a four-tone standard pattern, 3\4 is a pattern matching processing section, 3'01 is an analog voice input, 3
02 represents a voice signal, 303 represents a voice pattern, and 304 represents a four-tone identification signal.

The microphone 2 converts audio into an analog electrical signal, and this analog electrical signal is sent to the A/D converter 31. A
/D converter 3l converts this analog electrical signal into a digital electrical signal, and converts the digital electrical signal into audio analyzer 3.
Send to 2. In order to extract as information a pattern that can be compared with the four-tone standard pattern, the voice analysis section 32 performs the following: - Normalization on the time axis to correct the length of the voice; and Normalization on the strength of the voice. A certain part of the fundamental frequency that characterizes the pitch of the voice is extracted from the normalized audio signal, and a pattern in which it changes over time is extracted and sent to the pattern matching processing section 34 as an audio pattern. The pattern munching processing section 34 matches the received voice pattern with the four-tone standard pattern 33 and extracts four-tone information of the voice pattern. The Chinese four-tone recognition device shown in Figure 4 is:
Ill listen to the audio! It is not necessary to recognize all the characters that are 1, and there is no need to divide small spaces into phonemes of speech.

・There is no need to recognize Pinyin.

It has the advantage of Therefore, basically, only four patterns are required for the four-tone standard pattern, and the storage capacity is small. Furthermore, since there are few patterns, the time required for processing in the pattern matching processing section is also extremely short.

[Effects of the Invention] As is clear from the above description, according to the present invention, since a Chinese four-tone recognition device is used, the operator can automatically input four-tone information just by reading out Chinese characters. I can do it. In the conventional Pinyin-Kanji Hen-ta method, the operator has to think about the four tones of the Chinese kanji, which he or she is hardly aware of, when inputting, which puts a burden on the operator who inputs the keys, and also reduces input time. However, according to the present invention, such problems can be solved and Chinese input can be performed efficiently.
