Description

[Detailed Description of the Invention] [Summary] A pronunciation/accent learning device for learning the pronunciation/accent of a foreign language uses a manual device for inputting the spelling of words, a pronunciation rule dictionary, and a longest match method to create pronunciation rules. A spelling/phonetic symbol converter that searches a dictionary and converts it into phonetic symbols; and a display device that displays the phonetic symbols converted for each divided spelling and the combined phonetic symbols converted for each of these divided spellings. The system is equipped with at least the following, and displays the phonetic symbols that correspond to the human spellings.

[Industrial application field]

The present invention relates to a pronunciation/accent learning device configured to display pronunciation symbols, accent positions, and pronunciation rules for input foreign language words.

[Problems to be solved by conventional technology and invention] Conventionally,
Some pronunciation/accent learning devices respond to input foreign language words by displaying their pronunciation symbols and accent positions on a display device. This device has a table containing the spelling, phonetic symbol, and accent position of each word for each word in its memory, finds a word from the table that matches the manually written word on an l-to-l basis, and displays the phonetic symbol and accent position on the display. It is possible to answer by displaying the following. In the case of such devices, we do not know the reason why the pronunciation and accent are the same,
It was just a one-sided teaching. Therefore, the pronunciation and accent position of each word are only learned mechanically, and there is a problem in that the learning efficiency is extremely low.

As a solution to this problem, it is conceivable to add an item to the table indicating the reason for the pronunciation and accent position. However, in this case, there is a problem in that a large memory is required to handle many words.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention divides the spelling of a word, and prepares pronunciation rules and accent rules corresponding to the divided spellings in advance as a dictionary.
By repeatedly matching the spelling of the input word with the dictionary using the longest match method to obtain the desired phonetic symbol and accent position, the phonetic symbol of many words can be created with a small amount of memory. In addition to displaying the accent position, the applied rules are also displayed to inform the pronunciation and the reason for the accent.

FIG. 1 shows the basic configuration of the present invention. In the figure, 1 is an input device, 2 is an accent position determination unit, 3 is an accent rule dictionary, 4 is a spelling phonetic symbol conversion unit, 5 is a pronunciation rule dictionary, 6 is a rule presentation unit, 7 is a phonetic symbol display unit, and 8 is a phonetic symbol display unit. Represents a display device.

In FIG. 1, an input device 1 is used to manually spell words.

The accent position determination unit 2 searches the accent rule dictionary 3 to determine the accent position corresponding to the spelling of a word manually entered from the input device 1.

The spelling/phonetic symbol conversion unit 4 divides the spelling of the word input from the input device 1, searches the pronunciation rule dictionary 5 using the longest match method, and converts the divided spellings into desired pronunciations. .

The rule presentation section 6 displays on the display device 8 the accent positions and pronunciation rules determined and converted by the accent position determination section 2 and the spelling/phonetic symbol conversion section 4, respectively.

The phonetic symbol display section 7 displays the syllable symbol converted by the spelling phonetic symbol conversion section 4 on the display device 8.

[Effect]

Adopting the configuration shown in FIG. 1, when the spelling of a word is input from the input device 1, the accent position determining section 2 searches the accent rule dictionary 3 and determines the accent position.

The determined accent rule is displayed on the display device 8 by the rule presentation section 6. Next, the spelling/phonetic symbol conversion unit 4 divides the spelling of the input word, searches the pronunciation rule dictionary 5 for the divided spellings using the longest match method, and determines the corresponding pronunciation rule (symbol). be done. The determined pronunciation rules (symbols) are displayed on the display device 8 by the rule presentation section 6 in association with each divided spelling. In addition, the phonetic symbol display section 7 displays the phonetic symbol display section 7 on the display device 8, in which the phonetic symbols for each divided spelling are combined. Note that in the case of German, etc., the accent position determination unit 2 is not necessarily required, since the accent position can be almost always known from the spelling, as will be described later.

As explained above, by inputting the spelling of a word, the pronunciation rule corresponding to the divided spelling of the word, the pronunciation symbol and the accent position corresponding to the spelling of the word are presented.

〔Example〕

FIG. 2 shows the configuration of one embodiment of the present invention. In the figure, 4-1 is a spelling phonetic symbol converter, 5-1 is a pronunciation rule dictionary, and 6-
1 represents a rule presentation section, and 7-1 represents a phonetic symbol display section. Note that 1 and 8 in the figure are equivalent to those shown in FIG.

FIG. 2 shows an example configuration applied to German. In this case, the accent position determination section 2 in FIG. 1 has been deleted because the accent position can be almost determined from the divided spellings.

In FIG. 2, when the spelling of German (for example, "5tehen" shown in FIG. 3) input from the input device 1 is notified to the spelling phonetic symbol converter 4-1, the spelling phonetic symbol converter 4-1 searches the pronunciation rule dictionary 5-1 using the longest match method, and finds the pronunciation symbol (for example, the third The converted pronunciation symbols are sequentially converted into (C), (shown using f and (G)).The converted pronunciation symbols are displayed on the display device 8 as pronunciation rules by the rule presentation section 6-1. Furthermore, the phonetic symbol for the spelling of the word, which is a combination of the respective phonetic symbols, is displayed on the display device 8 as a phonetic symbol by the phonetic symbol display section 7-1.

Next, the operation will be explained using FIGS. 3 and 4.

In FIG. 3, when the spelling of the German word ``5tehen'' is input from the input device 1, the ``Δ'' representing the beginning and end of the word is respectively spelled out as in the spelling ``85tehan△'' shown in diagram (A). will be added.

This spelling with the addition of the beginning and end of the word “Δ5tehe”
First, the longest match method is used to search for a pronunciation rule (encircled by a dotted line in diagram (B)) that converts "Δst" into a pronunciation.

The pronunciation symbols indicated by this pronunciation rule are illustrated (C)
It is converted into a phonetic symbol corresponding to the first spelling "Δst" as shown by using .

Second, the pronunciation rules for converting “eh” into pronunciation (as shown (
Search for the item enclosed by the dotted line using D). The pronunciation symbol indicated by this pronunciation rule is converted into the pronunciation symbol corresponding to the second spelling "eh" as shown in the diagram.

Thirdly, a pronunciation rule (encircled by a dotted line in FIG. 1F) for converting "enΔ" into a pronunciation is searched.

The pronunciation symbols indicated by this pronunciation rule are illustrated (G)
It is converted into the phonetic symbol corresponding to the third spelling "enΔ" as shown by using .

The spelling of the word entered as above is “5tehe”
The results of the search corresponding to n'' are displayed on the display device 8 as shown in FIG.

The first line in Figure 4 shows the spelling of the input word “5te”.
hen” and the phonetic symbols for this spelling are written.

From the second line onwards, the pronunciation rules (encircled by dotted lines using diagrams (B), (D), and (F) in Figure 3) that were applied when converting this spelling into phonetic symbols are listed respectively. It has been described. As explained above, the present invention, as shown in FIG. , it is possible to know the reasoning behind why the pronunciation is the way it is and why it is accented, and it is possible to learn pronunciation and accents efficiently and systematically. Further, according to the embodiment shown in FIG. 2, for example, there are about 300 pronunciation rules for about 800 basic words in German, and the size of the pronunciation rule dictionary 5-1 is about 2.4 KB. .

This requires approximately 1/10 the amount of memory compared to the approximately 32 KB required if the dictionary contained spelling, phonetic symbols, and applicable rules for each of the 800 words. It will be over.

Next, the operation of the accent position determining section 2 shown in FIG. 1 will be explained in detail using FIGS. 5 to 7.

In FIG. 5, ■ indicates a state in which accent rules are read from the accent rule dictionary 3. In FIG.

In the figure, ■ indicates a state in which it is determined whether or not the accent rules read from the accent rule dictionary 3 are finished. YE
In the case of S, all searches have been completed, so the series of procedures ends. In the case of No, repeat the steps below (■) in the figure.

■ in the figure indicates a state in which the spelling pointer is set to the beginning of the input spelling.

In the figure, ■ indicates a state in which it is determined whether the number of characters existing on the right side of the spelling pointed to by the spelling pointer is greater than or equal to the number of characters stored in advance in the accent rule dictionary 3 as an accent rule.

In the case of No, repeat the steps below (■) in the figure. YE
In the case of S, in the figure, matching is performed, that is, an accent rule using the same spelling as an index is searched. Then, it is determined whether matching was successful or not by ■ in the figure, and Y
In the case of ES, after determining the accent position at ``■'' in the figure, the steps below ``■'' in the figure are repeated and executed. In case of NO,
Move the spelling pointer one character to the right at ■ in the figure, and repeat the steps following ■ in the figure.

By the above procedure, the accent position of the spelling of the word manually input from the human input device 1 is determined. This determined accent position is displayed on the display device 8 by the rule presentation section 6.

Incidentally, FIGS. 6 and 7 are flowcharts that describe in detail the matching procedure (2) in FIG. 5 and the accent determining procedure (2) in the figure, respectively. In the matching procedure shown in FIG. 6, characters are first matched, and then accented parts are matched. "C" in the rule matches a manually spelled consonant, and V" indicates a match with a vowel. In addition, the illustrated accent determination procedure in Figure 7 uses the spelling accent pointer (the accent part of the input spelling). The accent information is stored in the buffer by moving the accent information one character at a time to the right until the pointer (pointer pointing to 2), the character string to be replaced (accent information) is added to the end of the buffer.Furthermore, the spelling accent pointer is moved to the right by the number of characters in the character string to be replaced. , and then adds the following accent information to the buffer.Finally, the contents of the buffer are copied to the accent part of the input spelling to finish determining the accent.

FIG. 8 shows an example data structure. The spelling shown in the upper row of the figure “
The accent of "$become$" is represented by the accent part "$0011118" shown in the lower row. Here, "0゛" is a weak tone, 'l'' is a string tone, and "$" is the beginning or end of a word.

Furthermore, the symbol "-" below indicates that the accent is undetermined.

Figure 9 shows the order in which the rules are applied. In other words, the spelling shown in Figure 9 (a) is "$ b e co m a
Based on the accent application rules shown on the right side, "$00" is applied to "$be" as shown in Figure 9 (b).
” is determined.Next, in the same manner, as shown in FIG. 9(C), “1111$” is determined for the remaining “come$”.
” is determined.

As described above, the accent part "5ooztts" is determined for the spelling "$becomeS" by the procedures shown in FIGS. 9(a) to 9(c), respectively.

〔Effect of the invention〕

As explained above, according to the present invention, the spelling of a word is divided, pronunciation rules and accent rules corresponding to the divided spellings are prepared in advance as a dictionary, and the spelling of the input word is The system uses a longest-match method to repeatedly match the words to obtain the desired phonetic symbols and accent positions, so it is possible to display the phonetic symbols and accent positions of many words with a small amount of memory. At the same time, the applied pronunciation rules are displayed and the learners are informed of the reasons why they are pronounced the way they are, allowing them to not only learn the pronunciation of individual words, but also to carry out systematic learning efficiently. .
