Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a foreign language learning device which enables a learner to learn a foreign language while presenting the learning contents to the learner one by one.

[0002]

2. Description of the Related Art In recent years, a foreign language learning system has been developed in which a foreign language can be learned by a personal computer or the like by using a voice database and a voice output function.

[0003] In such a foreign language learning system, a learner uses audio data output from a personal computer or the like according to a pre-programmed learning sequence based on a predetermined database pre-stored in the computer or the like. On the other hand, by answering the questions for confirming the results of the hearing, it is possible to learn the foreign language by yourself.

[0004]

When listening to or pronouncing a foreign language, what is the mother tongue (first language) of the listener / speaker is an important factor. It is known that depending on this mother tongue, the learner's degree of difficulty or difficulty in learning the foreign language is affected. Therefore, in learning a foreign language, it is considered that using a learning method considering the learner's native language leads to an effective training method.

However, it is not clear what kind of learning procedure (learning sequence) is created depending on such a difference in the mother tongue and whether it is effective for the learner to learn.

On the other hand, the appearance of such a difficult pattern in foreign language learning varies depending on the attribute of the stimulating sound used for training. That is, in addition to taking into consideration that the learning difficulty varies depending on the learner's attributes such as what the learner's mother tongue is, the sequence of each stimulus for each foreign language learner Considering whether to perform sound training is also an important factor for improving learning effect.

However, it is not always clear at present what kind of learning sequence is effective based on both the attribute of the stimulating sound and the attribute of the learner.

FIG. 8 is a conceptual diagram showing the relationship between the learner's attributes and the stimulating sound, and FIG. 9 is a conceptual diagram showing the relationship between the stimulating sound's attributes and the learner.

The above description is summarized with reference to these figures. As shown in FIG. 8, even when the same voice is given to the learner from the learning system, the learner A is given this sound. And the case where this sound is given to the learner B, the difficulty level thereof differs depending on the learner's attributes (age, sex, mother tongue, etc.). Therefore, in a single predetermined learning sequence, the learner's attributes are different. It is difficult to carry out effective learning according to.

On the other hand, as shown in FIG. 9, even when different stimulating sounds are given to the same learner and the listening training is performed, not only is the difficulty level different for each stimulating sound, The degree of difficulty changes depending on which speaker the same stimulus sound is uttered, in what word is uttered, and in what group of words is uttered.

Therefore, the foreign language learning system considers each of the attributes of the learner and the attributes of the stimulus sound given to the learner as described above, and in the sequence suitable for the level of the learner. It is desirable that the system is presented and trained by learners. However, conventionally, the learning program has not been presented to the learner according to the sequence in which both the learner's attribute and the stimulus sound attribute are taken into consideration.

The present invention has been made in order to solve the above-mentioned problems, and its purpose is to make the learner more considerable in consideration of both the attribute of the learner and the attribute of the stimulating sound. It is to provide a foreign language learning device that enables effective foreign language learning.

[0018]

1 is a schematic block diagram for explaining the configuration of a foreign language learning apparatus 100 according to the present invention.

Referring to FIG. 1, a foreign language learning device 100.
Is a stimulus attribute database 10 for storing learning data and test data in association with stimulus sound attributes,
And a personal information database 20 for storing individual learner information.

The stimulus attribute database 10 includes a word database 12 for storing voice data of each word constituting the learning test data, and an utterance for storing voice data corresponding to the utterance of each word in the word database 12. The database 14 and the speaker database 16 for storing attributes about the speaker who uttered each word, and each word should be presented to the learner as what kind of word group, for example, “conflict pair” described later. And a word group database 18 storing information about

The personal information database 20 is a native language database 22 that stores what the learner's native language is.
And an age database 2 for storing learner age
4, a gender database 26 for storing the learner's gender, and a proficiency level database 28 for storing the learner's proficiency level.

The foreign language learning apparatus 100 further includes a learning sequence database 30 that stores data regarding the order in which test data is presented and the contents of the listening test are presented according to the course selected by the learner. .

The foreign language learning apparatus 100 also generates a sequence in response to the information of the difficulty level thereof being changed in the data in the stimulus attribute database 10 according to the learning of a large number of learners as described later. Data corresponding to the information in the database 30 is extracted from the stimulus attribute database 10 and a sequence generation control unit 40 for generating a learning sequence, and a sequence generation control unit 4
Character data such as voice data output from 0 or data of options to be selected by the learner, graphic data, etc. are output to an information transmission network such as the Internet 200, and given from the learner via the Internet 200 or the like. Interface unit 5 for giving personal information and answer information of the learner himself to the sequence generation control unit 40
With 0 and.

On the other hand, through the information communication network such as the Internet 200, each learner's terminal 300.1-30
0. N (N: natural number) are connected. By allowing a large number of learners to access the foreign language learning apparatus 100 via the information communication network such as the Internet 200, it is difficult to generate a learning sequence as described later. It is possible to collect a large number of frequency data and improve the reliability of learning sequence generation.

That is, the foreign language learning apparatus 1 according to the present invention.
As described in detail below, 00 indicates the pattern of the degree of difficulty present in the stimulus sound presented to the learner by learning the learner's mother tongue and the individual's proficiency level (how much the learner has mastered the foreign language). It is possible to change the training sequence according to the learner's attributes such as age and sex. Further, the foreign language learning device 100 according to the present invention.
Is not only the attributes of the learner, but also the attributes of the stimulus sound given to the learner, such as the speaker or in which word is pronounced, and what word group to present to the learner. The training sequence for learners can be changed flexibly based on attributes such as. Here, the “word group” is, for example, / r / of the target stimulus sound.
It is possible to use word pairs such as "red" and "led", which are word pairs that differ only by and / l / (called "opposing pairs").

Therefore, in the foreign language learning apparatus 100 according to the present invention, the learning data of a large number of learners are sampled using the information communication network such as the Internet 200, and the result is used as the initial learning data. By dynamically reflecting it, the difficulty level corresponding to each stimulus attribute of the training voice is changed, and an optimal learning material structure is created based on the learner's attribute, and the stimulus attribute and the learner Realizes foreign language learning that reflects both attributes of.

The foreign language learning device 100 according to the present invention will be described in detail below. In FIG. 1, the data stored in each of the databases 12 to 18 in the stimulus attribute database 10 and the data stored in each of the databases 22 to 28 in the personal information database 20 are associated with each other and are relational. It has become a database.

FIG. 2 is a conceptual diagram showing an example of the relation of relational data stored in the stimulation attribute database 10 and the personal information database 20.

As described above, the stimulus sound to be learned given to the learner, for example, when Japanese learn English, "R", "L" and "B" which are apt to cause mistakes in pronunciation and hearing. And "V", "S" and "T"
The stimulus sound such as H "is presented to the learner in pairs. In this case, it is not simply presented to the learner as a consonant,
For example, in the case of "R" and "L", the data is presented to the learner as an "opposing pair" such as "right" and "light". In addition, "B" and "V"
The pair of stimulus sounds is similarly presented to the learner as an opposing pair such as “boat” and “vote”. At this time, it is said that not only is the “conflict pair” in the narrow sense in which only the target stimulus sounds are different and the pronunciations of other vowels and consonants are common, but the target stimulus sounds are different and the pronunciations of other vowels and consonants are similar. It is also possible to use a broad sense of “conflict pair”. Further, such a confronting pair is not always an alternative. For example, when a vowel is a learning target, a confronting pair may be formed by a plurality of stimulating sounds.

The database of stimulating sounds to be learned by the learner stores all the stimulating sounds in the foreign language to be learned, and such stimulating sounds are stored in the above-mentioned conflicting pair, for example. It is associated. A plurality of confronting pairs, which are pairs of words to be presented to the learner, correspond to such stimulus sounds.

Further, for each confrontation pair, data of each confrontation pair when not only one speaker but a plurality of speakers, for example, n speakers, are stored.
For example, with respect to the speaker 1, attributes of the speaker who speaks (age, gender, etc.) are associated as speaker attributes, and the voice information produced by the speaker 1 is stored as corresponding data. Further, as will be described later, the difficulty level is calculated for each speaker according to the learning progress of the learner, and the difficulty level is also stored in association with the speaker.

Regarding the difficulty level, not only the speaker but also the difficulty level is associated with each conflict pair, for example, by averaging the speakers regardless of their attributes.
Based on the difficulty level of each conflict pair, further, for example, by taking the average value, the difficulty level of the stimulation sound to be learned is also calculated, and the difficulty level of each stimulation sound is associated as data. Has been.

FIG. 3 is a conceptual diagram for explaining in more detail the degree of difficulty associated with each conflict pair.

The difficulty level that the learner feels for each conflict pair differs depending on the learner's attributes, such as sex, age, and mother tongue, so the difficulty level parameter is stored corresponding to each attribute. .

For example, in correspondence with the mother tongue 1, for each sex of men and women and for each age of each sex, for example, teens, 2
Cumulative number of cumulative presentations that the confrontation pair was presented to the learner for each of the 0s and 30s, and the number of times the learner correctly answered which of the confrontation pairs was pronounced. The number of correct answers is stored.

Further, data of the presented average level is also stored for each age. Here, the “presentation average level” is an average value indicating at which difficulty level the stimulus sound has been presented to the learner in the past, which will be described later.

Here, the "difficulty level" is not particularly limited, but, for example, when a plurality of word groups (for example, opposing pairs) are divided in advance into a predetermined number of groups in the order of difficulty, It means the number of groups to which the target word group belongs. In FIG.
If a plurality of opposing pairs corresponding to R and L are divided into 10 groups according to the difficulty level, the difficulty level will be expressed by 10 levels.

As the learner's attribute, in addition to sex and age, data showing the learner's proficiency such as the learning period of the foreign language to be studied and the level of examinations by other institutions may be used. It is possible.

The difficulty level can be calculated, for example, by the following equation using these three parameters.

(Difficulty level) = (cumulative number of correct answers) × (presentation average level) / (cumulative number of presentations) Such parameters are stored for the number of stimulating sounds × attributes. That is, the database accumulates the number of parameters of the learner's mother tongue, the learner's sex and the learner's age, and the number of stimulus sounds.

When the learner actually learns, the above-mentioned "cumulative number of correct answers" and "cumulative number of presentations" are updated in real time. On the other hand, the “presentation average level” is updated when a learning sequence is generated for a learner.

In addition, an area for storing how many times and at what level the presentation of a conflicting pair to the learner (hereinafter referred to as “trial”) is stored is provided in the database 10 for each conflicting pair. And is updated in real time as you study. By storing such data, the level of difficulty for the learner moves up and down according to the grade of the learner. Therefore, it is possible to confirm which level of trial is often presented to learners.

Although not particularly limited, the degree of difficulty associated with each speaker shown in FIG. 2 is similarly "accumulated number of correct answers", "accumulated number of presentations" and "presentation average" for each utterance data. It is possible to accumulate and update "levels" in real time.

Based on this "presentation average level", the opposition pair to be presented to the learner and the utterance of the speaker are selected.

FIG. 4 is a flowchart for explaining the flow of learning performed by foreign language learning apparatus 100.

When the learner enters the foreign language learning device 100 through the information communication network such as the Internet 200 and starts learning (step S100), the learner:
The attribute data of the learner such as age, gender, and mother tongue is displayed on the terminal 30.
0. Information communication network 20 from i (i: natural number, 1 ≦ i ≦ N)
It is transmitted to the foreign language learning device 100 via 0 (step S102).

Next, the foreign language learning apparatus 100 presents the learner with a selectable learning course, and the foreign language learning apparatus 100 determines which course the learner should select.
(Step S104).

Here, the contents of the learning contents performed as follows have a hierarchical structure of course, step, level, speaker, and trial.

Here, the "course" selected by the learner in step S104 means that the learner selects, for example, "R and L training", "B and V training" among consonant training.
It is classified by the consonant to be listened to, such as which listening learning such as "S and TH training" is to be performed. Furthermore, not only consonants but also courses can be provided for each vowel that is the subject of listening. Alternatively, a course may be provided for each consonant or vowel targeted for speech training.

Subsequently, the learner has previously learned the foreign language learning device 1
00 receives the prepared ability test (step S106). As a result, the level of the learner is determined, and which level of "conflict pair" or the like is presented as a learning target in the course selected by the learner according to the determination level, as will be described later. Is selected.

Subsequently, the learner selects which step in the course he / she has selected to start learning (step S108).

It is assumed that the plurality of steps are constructed so that the average difficulty level thereof gradually increases. Furthermore, each step is further divided into levels according to the degree of difficulty. According to the ability test conducted at the start of learning the course, the grade is shifted to an appropriate level for the learner, and the learning is started. Therefore, the foreign language learning device 1
At 00, a learning sequence is created according to the step selected by the learner and the result of the ability test (step S110).

In accordance with such sequence creation, for example, listening learning of the learner is performed at each step (step S112), and the sequence generation control unit 40.
When each step is completed, determines whether to proceed to the next step (step S114). This step S
At 114, when the learning of the highest step is finished, the learning of the course is finished.

Subsequently, the learner transmits a judgment as to whether or not to try another course to the foreign language learning apparatus 100 (step S116), and when the course is selected,
When the process returns to step S104, and the learning ends, the learning sequence ends through the above process (step S120).

FIG. 5 is a flow chart for explaining the contents of the step learning shown in FIG.

When learning of a certain step is started (step S200), based on the result of the ability test, based on the sequence generated by the learning sequence generating step (step S110) of FIG. 4, according to the level of the learner. The speaker is selected (step S202), and
The stimulus sound to be learned is presented to the learner (trial) in sequence. More specifically, the learner's terminal 300.
Speaking from speaker i (not shown), and display of character data of the opposite pair to be uttered (not shown)
Are sequentially displayed.

The learning in each step is composed of several blocks, for example, three blocks in FIG.

First, the pronunciation of any word by the speaker 1 selected in step S202 among the plurality of conflict pairs selected corresponding to the level of the learner in the selected course is given to the learner. Are presented (step 204).
On the side of the learner, the selected result of the character data displayed on the display is returned to the foreign language learning device 100 according to the listening result.

The presentation of such an opposed pair for each speaker is performed over a plurality of blocks thereafter (steps S206 and S208).

Here, in each block, a stimulus sound produced by one speaker is used. In addition, each block
It is configured by collecting a plurality of minimum units of learning called "trial" described above. In each trial, as described above, one utterance of a certain speaker is reproduced for the conflicting pair selected by the sequence control unit 40 in response to the stimulating sound of the course selected by the learner, and on the screen, It is assumed that the learner clicks and selects the button indicating the option displayed in the.

The order of the presented opposing pairs in each block may be randomly changed.

When the learning of the block corresponding to a plurality of speakers is completed, it is judged whether or not the level is completed (step S210). If it is determined in step S210 that the level has not been completed,
The learning shifts to a level lower than the current level (step S212), and the process returns to step S202 again.

On the other hand, if it is determined that the level has been completed, it is subsequently determined whether or not the completed level is the highest level in the step (step S212). When it is determined that the completed level is not the highest level, the level is raised from the current level (step S216), and the process is performed again in step S2.
Return to 02.

When the completed level is the highest level, the process of the step is completed (step S22).
0).

In this way, even when learning each level of each step, the level of the learning target is raised or lowered according to the result. The number of levels can be different depending on the step, and can be divided into, for example, 10 to 20 levels.

FIG. 6 is a flow chart for explaining a flow in which the sequence generation control unit 40 performs in real time a precondition for generating a learning sequence in the sequence creation step (step S112) shown in FIG. Is.

That is, the sequence generation control unit 40
According to the procedure described below, the calculation of the difficulty level is sequentially updated in real time for all the stimulation sounds.

The sequence generation control unit 40 monitors whether the trial is presented to the learner and whether the answer to the trial is returned from the learner (step S30).
0).

When there is a presentation to the learner and a reply to the answer, the "cumulative number of correct answers" and "cumulative number of presentations" corresponding to the utterance data of each speaker and the opposing pair are updated (step S).
302).

Subsequently, it is determined whether or not the learner has selected the step described in step S108 of FIG. 4 (step S304). If step selection has not been performed, the process returns to step S300.

On the other hand, if step selection is performed,
The "presentation average level" is updated (step S30).
6) That is, the "presentation average level" is updated when a learning sequence is generated for a certain learner.

Subsequently, the difficulty level is updated (step S308). This difficulty calculation is as described above.
It is possible to calculate for each utterance data of each speaker or for each conflict pair by (cumulative number of correct answers) × (presentation average level) / (cumulative number of presentations).

Further, based on the updated difficulty level of the opposing pair, the difficulty level (average of the difficulty level of the opposing pair) is calculated for all the stimulating sounds.

When the above process is completed, the process returns to step S300 again. FIG. 7 shows the sequence creation step (step S112) shown in FIG.
7 is a flowchart for explaining a process performed by the sequence generation control unit 40.

When the learning sequence creation process is started (step S400), the sequence generation control unit 40
First, it is determined whether the level of the learner corresponds to the level of difficulty of the selected step (step S4).
02) If the level difference is large, the learner is instructed to select another step (step S404).

When it is determined that the step selection is appropriate (step S402), the sequence generation control unit 40 searches the stimulus attribute database 10 based on the result of the ability test of the learner (step S406).

The sequence generation control section 40 is presented to the learner according to the difficulty level calculated for each conflict pair, the learner's attribute, and the level currently designated for the learner. An opposing pair to be selected is selected (step S408). At this time, the sequence generation control unit 40
Selects the conflicting pairs presented for each step such that the steps within the selected course are progressively increasing in their average difficulty. It should be noted that, in each step, although the average difficulty level is gradually increased, the difficulty level may be overlapped between the higher level difficulty level of a certain step and the lower level difficulty level of a step above it. I shall.

With the above, the learning sequence creation is completed (step S410). Note that step S408 in FIG.
In the process of selecting which conflict pair is selected, the selection process can be performed based on the following contents.

First, as the first procedure, the cumulative number of presentations for each conflict pair is checked, and a fixed ratio (eg, 10%) to the total number of trials in the learning sequence is checked.
For the number of trials of, the conflicting pair with the least number of presentations is preferentially inserted into the sequence.

In other words, from a conflicting pair that has been presented a few times up to the previous time, the learner is presented with a higher probability than this time.

However, when performing such insertion,
A certain number of conflicting pairs to be inserted are sorted in advance according to the degree of difficulty in order of increasing cumulative number of presentations, and the insertion is performed according to each degree of difficulty.

Next, as a second procedure, the conflicting pairs which have not been inserted in the learning sequence to be created this time by the above-mentioned first procedure are rearranged according to the degree of difficulty. Then, after dividing by the number of levels (for example, if there are 100 opposing pairs in the front part and the number of levels is 10 and then dividing by 10 pairs), the pair with the smallest cumulative number of times in each division unit Assign to each level in order to create a learning sequence.

That is, for example, when the sequence has a vacancy of 50 pairs after preferentially assigning an opposed pair having a small cumulative presentation number in the first procedure, the cumulative number is small for each level-divided group. 5 more from the pair
We will allocate them in pairs.

Further, in step S202 shown in FIG. 5, when the process of determining which speaker's utterance is to be selected for the selected conflicting pair is performed similarly to the above-described conflicting pair selection. In addition, it is possible to preferentially perform the selection process from the utterance of the speaker whose cumulative number of presentations is small.

With the above configuration, the learning data to be presented to the learner's level is optimal according to the learning result data learned by many learners via the information transmission network. Will be selected to have the desired learning effect.

The embodiments disclosed this time are to be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description but by the claims, and is intended to include meanings equivalent to the claims and all modifications within the scope.
