Abstract

PROBLEM TO BE SOLVED: To save a storage area for a dictionary for storing correspondence between foreign language notation and its YOMIGANA (Japanese pronunciation syllabary printed alongside foreign language characters) and to make it possible to generate YOMIGANA also for foreign language notation not recorded in the directionary. SOLUTION: A pointer is set up to the leading character of a character string expressed by foreign language notation (S10), whether the character pointed out by the pointer is a vowel or not is judged (S11), and when the character is not a vowel, whether the character is 'N' or not is judged (S12). When the character is 'N', the pointer is moved forward only for one character (S16), and when the character is not 'N', whether a character next to the pointed character is a vowel or not is judged (S13). When the succeeding character is a vowel, the pointer is moved forward only for one character (S16). When the character is not a vowel, a vowel is inserted into a space just before the pointed character (S14) and the pointer is moved to a character succeeding the inserted character (S16). When the pointer moved forward exceeds the final character of the character string or not is judged (S17), and when the pointer does not exceed, processing is repeated from the judgement (S11) and Roman characters are converted into KANA (square form of Japanese syllabary) characters (S18) to end the processing.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Japanese phonetic alphabet generating device for generating Japanese Japanese phonetic characters from an alphabetical representation of a foreign language, and more particularly to a Japanese word phonetic generating device capable of generating Japanese phonetic characters even for unknown words.

[0002]

2. Description of the Related Art Conventionally, a technique for generating Japanese phonetic characters from a foreign language alphabetic notation has been used to record a specific word using a dictionary in which the correspondence between the foreign language notation and the Japanese phonetic characters is recorded in advance. Only the foreign language notation that existed could be converted into Japanese. As an example of such technology, EDR (Japan Electronic Dictionary Research Institute)
A Japanese dictionary is created from a foreign-language alphabet by constructing a large-scale dictionary containing a remarkably large number of vocabularies so that it can be used in various environments and applications like the electronic dictionary created by It is possible to

Further, a Kana-English character dictionary is prepared, and it has a function of obtaining English spelling from a Kana character string.
No. 59, Kana-Kanji conversion processing device, etc. are known.

[0004]

As described above, in the prior art, since the dictionary records the correspondence between the foreign language notation and the Japanese pronunciation, a large storage area is required to correspond the foreign language notation to the Japanese pronunciation. Need. In addition, there is a problem in that readings cannot be generated for foreign language notations not recorded in the dictionary.

Particularly in computer systems, it is necessary to deal with new words related to newly developed technology one after another, proper nouns of specific devices and software, and foreign language notations and abbreviations such as English tend to be frequently used. . It is impossible to register all of these in advance even with a large-scale dictionary.

In view of the above-mentioned point, an object of the present invention is to generate a phonetic alphabet for a foreign language notation not recorded in the dictionary and to reduce a storage area for storing the dictionary. To provide.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a Japanese-orientation-gardening device of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a Japanese-original generation device 10 according to an embodiment of the first aspect of the present invention.

When the character string 101 is inputted, the vowel inserting means 13 receives the character string 101 and sequentially detects the vowel and consonant sound 11 from the first character.
Pass the character 102 to. The vowel / consonant discrimination unit 11 discriminates whether the character passed from the vowel insertion unit 13 is a vowel or a consonant, and notifies the consonant continuous detection unit 12 of the discrimination result 103.

The consonant continuous detection means 12 stores the discrimination result received from the vowel / consonant discrimination means 11 immediately before,
The vowel insertion unit 13 is notified of a consonant continuous determination result 104 indicating whether both the discrimination result newly received from the vowel / consonant discrimination unit 11 and the immediately preceding discrimination result are consonants.

The vowel inserting means 13 is a consonant continuity detecting means 1
When the consonant continuity determination result 104 from 2 is received and consonants are continuous, a vowel is inserted between them.

The vowel inserting means 13 sends the characters of the character string 101 to the vowel / consonant discriminating means 11 to the end, and upon receiving the notification from the consonant continuity detecting means 12, inserts the vowel when it is necessary. , Romaji notation 105
Is output. Further, instead of outputting the romanized notation for reading, the vowel inserting means may convert the romanized notation into kana and output it.

Next, the flow of processing according to the first aspect of the present invention will be described. FIG. 4 is a flow chart showing the flow of processing of the Japanese-speaking device in one embodiment of the first invention.

In order to process the character string in the foreign language notation from which the calligraphy is to be generated from the beginning, the pointer is first set to the beginning character (step S10). The vowel / consonant discrimination unit 11 determines whether the character pointed by the pointer is a vowel (step S11). The consonant continuity detecting means 12 notifies the vowel inserting means 13 that the consonant is not continuous if the determination result of the vowel / consonant determining means 11 is a vowel,
The vowel inserting means 13 advances the pointer as it is by one character (step S16). If the determination result of the vowel / consonant discrimination means 11 is not a vowel, it is determined whether or not the character is "N" (step S12). If "N", the consonant continuity detection means 12 does not have a consonant continuity, Is notified to the vowel inserting means 13, and the vowel inserting means 13 advances the pointer as it is by one character (step S16). If it is not "N", it is determined whether the next character pointed by the pointer is a vowel (step S1).
3) If it is a vowel, the consonant continuous detection means 12 notifies the vowel insertion means 13 that there is no consonant continuation, and the vowel insertion means 13 advances the pointer as it is by one character (step S16).

If it is not a vowel, the consonant continuous detection means 12
Informs the vowel insertion means 13 that there is a consonant sequence,
The vowel inserting means 13 inserts a vowel after the character pointed by the pointer (step S14), and advances to the character next to the character into which the pointer is inserted (step S15).

It is judged whether or not the result of advancing the pointer has passed the end of the character string (step S17), and if not passed, the vowel judgment (step S11) is repeated.
If it has passed, the alphabetic character string is read in Roman letters and converted into kana (step S18), and the process ends.

Next, a second embodiment of the present invention will be described. FIG. 2 is a block diagram showing the configuration of a Japanese-speaking device according to an embodiment of the second invention. Further, FIG. 5 is a flow chart showing the processing of the paper-original generation device according to the embodiment of the second invention.

In the embodiment of the present invention, in addition to the configuration of the first invention, the reading pattern conversion means 15 and a foreign character written in alphabets as shown in FIG. 8 are specified by a character string pattern shorter than a word. The foreign language character string pattern (82) is associated with the Japanese reading of, and a reading pattern table (81) recorded in association with the reading pattern (83) is provided for inserting vowels between consecutive consonants. First, by referring to the reading pattern table (81), it is checked whether or not the character string starting with the character pointed by the pointer matches the foreign language character string pattern included in the reading pattern table (step S41). In this case, the portion of the character string having the character string pointed to by the pointer at the beginning as the foreign language character string pattern is replaced with the reading pattern (step S42).

For example, the foreign language notation in the alphabet is "ACCENT" and the pointer is the first "C".
And refers to. Referring to the reading pattern table of FIG. 8, the character string "CCE" starting with the character pointed by the pointer
Is a foreign language character string pattern "C
Since it matches with "CE", its reading pattern "KUSE"
Replaces the character string "CCE" starting with the character pointed by the pointer and continues the processing. Finally, "AKUSENT
The Roman character string "O" is obtained and a phonetic "accent" is generated.

Similarly, "EARDROP" is "IYADO"
It becomes ROPU and produces a phonetic "eardrop". "SKETCH" produces "SUKETTI" and a phonetic "sketch". "CHEEK" produces "C"
HI-KU ", and produces" Cheek "which is a ghost.

Next, a third embodiment of the present invention will be described. FIG. 6 is a flow chart showing the flow of processing of the Japanese-speaking device in one embodiment of the third invention.

In the present embodiment, when inserting a vowel in the vowel inserting means 13 of the first and second inventions, it is determined whether the vowel "O" or "U" is inserted by the consonant pointed by the pointer. To do. In the present embodiment, it is determined whether the character pointed to by the pointer is "T" or "D" (step S21), and in either case, "O" is inserted after the character pointed by the pointer (step S22). ),
If neither, "U" is added after the character pointed to by the pointer.
Is inserted (step S23).

For example, the character string 101 "TEST"
Is input to the vowel insertion means 13, first, the pointer is set to the first character "T", this character is a consonant, and the next character is a vowel, so NO is determined in step S13, and the next character is selected. Since the pointer is advanced and the character is "E", YES is obtained in step S11, the pointer is advanced to the next character, "S" is a consonant, and the next character "T" is also a consonant, Since the character "S" to which the pointer is set is neither "T" nor "D", "U" is inserted after "S" in step S23, and the pointer is advanced to the next "T" that is inserted. . Since "T" is a consonant and there is no vowel next to the end of the character string, the process proceeds to the determination in step S21 and becomes YES, and "O" is inserted after "T". The pointer is advanced to the inserted character, but since it is beyond the end of the character string, processing ends,
The character string "TESUTO" is obtained. If you read this in romaji, you can convert it into kana notation called "test".

Next, a fourth embodiment of the present invention will be described. FIG. 3 is a block diagram showing the configuration of a Japanese-speaking device according to an embodiment of the fourth invention. Further, FIG. 7 is a flow chart showing the flow of processing of the Japanese-speaking device in one embodiment of the fourth invention.

In the present embodiment, in addition to the configurations of the first and second inventions, as shown in FIG. 9, a consonant (92) of the first character of consecutive consonants and a vowel (93) inserted after it. )
The vowel insertion means 1 is provided with a consonant vowel table 91 in which
When the vowel is inserted in No. 3, the vowel determined by referring to the consonant vowel table 91 is inserted (step S31).

Further, in the consonant vowel table 91, the vowels to be inserted in the case of the consonants "T" and "D" are "O" and "T" and "D", as in the third invention. The vowel to be inserted in the case of a consonant other than is "U".
