1 to 5, an English video chat using a foreign language conversation system according to an embodiment of the present invention will be described.

Figure 1 shows that learners video chat over a foreign language conversation system. Referring to FIG. 1, the learners 100 and 110 communicate with each other in English using a foreign language conversation system 130 connected through the network 120. The foreign language conversation system 130 provides the conversation examples of FIG. 2 to the learner terminals 101 and 111 so that the learners 100 and 110 can communicate smoothly.

FIG. 2 shows an example of a conversation that is needed when learners talk about a topic. Referring to FIG. 2, the dialogue example 200 includes a first replacement word 230 that can change a portion of a question 210, an answer 220, and an answer 220 related to a subject 'taste'. The question 210, answer 220 and first replacement phrase 230 of the dialogue example 200 represent a portion of the entirety, and the actual dialogue examples provided include more questions, answers, and first replacement phrases .

The way in which the learners 100 and 110 communicate using the conversation example 200 is as follows. For example, when the learner 100 asks a question based on the question 210 of the conversation example 200 displayed on the learner terminal 101, the conversation example 200 displayed on the learner terminal 111 by the other learner 110, Based on the answer 220 of FIG. With these questions and answers, learners who have never met will be able to continue conversation smoothly. Furthermore, the conversation example (200) allows a novice who has difficulty in asking and answering in English to speak in English.

Referring to FIG. 1, the foreign language dialog system 130 includes a question answering DB 131, a first replacement word DB 132, and a first controller 133.

The question answering DB 131 includes a question 210 composed of a plurality of questions 211, 212, and 213 necessary for the learner 100 and 110 to talk in a manner of asking and answering on a certain topic, (220) consisting of a plurality of answers (221, 222, 223). Here, answer sentences constituting plural answers are sentences having different contents or meanings. For example, there are four sentences in answer # 1 (221), and the answer contents are different. Similarly, answer 2 (222) also has four sentences, the contents of which are different. Therefore, the learner can choose a sentence containing the expression he / she wants to use or his / her situation and a suitable sentence.

The first replacement gear DB 132 includes a first replacement gear 230 composed of replacement gears 231, 232, and 233. The replacement word # 1 231 is a word, phrase, or clause that can change a portion indicated by a red character among # 1 answer (221) sentences. In FIG. 2, the portion of the answer (220) that can be changed is displayed in red letters. However, in addition to changing the color, the changeable portion can be displayed to be distinguished from other portions in various ways. Here, the changeable part is displayed in bold letters.

For example, in answer # 1 (221), " I often go to a place called Geulinnae." I often go "in the bold part of the sentence," I sometimes go "or" On special occasions, I go (I go on a special day ) "in the first replacement phrase (231 ) ". By replacing the bold part of the answer sentence with the replacement phrase, you can change the answer details in detail. In addition, the learner knows which part of the sentence is changed through the answer sentence that shows the replaceable part, and the content changes. The learner can also learn about writing English in a natural way by changing the sentence into a replacement phrase.

The question answering DB 131 and the first replacement query DB 132 may be included in one DB although the question answering DB 131 and the first replacement word DB 132 are distinguished from each other for convenience of explanation.

The first controller 133 sends the questions 210 and 220 stored in the question answering DB 131 and the first replacement word 230 stored in the first replacement word DB 132 to the learner terminals 101 and 111 ) As a conversation example (200). In addition, the first controller 133 displays the first replaceable words 230 among the sentences 220 to be distinguished from the rest. In this case, various methods other than the color differentiation method can be used.

Referring to FIG. 1, the foreign language dialog system 130 may further include a second control unit 134.

The second control unit 134 receives the questions selected by the learner among the questions 210, 220 and 230, and receives the replacement phrases, And displays a learner-specific conversation example on the learner terminal. The question 210, the answer 220 and the first replacement phrase 230 of the conversation example 200 are provided so that the learner can select questions, answers, and replacement phrases that are appropriate for him or her by means of a click or the like. That is, the learner can select one sentence suitable for him in the first question 211 including two sentences, select one sentence in the first answer 221 including the four sentences, and select " I (231), which includes three alternate phrases such as " sometimes go ", " on special occasions, I go " and " Do you know ".

For example, if the learner 100 selects "Do you know any good restaurants?", "Can you tell me where is it?" Or "How do you get there?" Among the questions 211, 212, " I often go to a place called Geulinnae.", "It's in the middle of Jongno's food alley, It's not easy to find .", "Take the subway to Hongdae Station. Then take Bus No. 3 from Exit 8 . " among the choices, and replace the phrase (231, 232, 233)" On special occasions, I go "," at the beginning ","It's easy to spot "," get out through Exit 8 and walk about 10 minutes "is selected, the second control unit 134 determines whether or not the answers including the answers selected by the learner and the changed answers The learner-to-learner conversation example 300 of FIG. 3 is displayed on the learner terminal 101. If the learner selects a reply sentence without a replacement sentence or does not select a replacement sentence, the selected answer sentence is displayed without change. When the second control unit 134 displays on the learner terminal 101, the English sentence and the corresponding Korean sentence can be displayed together as shown in FIG. 3, and only the English sentence can be displayed as shown in FIG.

It should be noted here that the first replacement phrase (231) is marked as " I often go to → I sometimes go | On special occasions, I go " and " Have you heard of → Do you know ". This is " I often go " and replaceable phrases that can be replaced are " I sometimes go " or " On special occasions, I go ", and replaceable phrases with " Have you heard of " mean " Do you know ". Therefore, if the learner 100 receives the answer " 1 " "I often go to a place called Geulinnae." The selection, if you select the "Do you know" from 1 to replace the phrase (231), and an error indication that the second controller 134 is a poor choice as a sound or the letter " Do you know "is not selected. As described above, " I often go " can not be changed to " Do you know ".

Although the first control unit 133 and the second control unit 134 are separated from each other for convenience of explanation, the first control unit 133 and the second control unit 134 may be included in one control unit.

Accordingly, the learner selects questions, answers, and first replacement phrases suitable for him in the question 210, answer 220, and first replacement phrase 230 of the conversation example 200, (300) of the learner. In this way, if you create a dialogue example by yourself, the conversation itself is easy to remember because it is your own story, not something that is not related to you. And it is like having a conversation with you because you are talking about yourself. In addition, learners can create their own conversation examples to suit various experiences. In other words, it is not boring to talk with various stories. And various answers and substitution phrases can be used to learn various expressions related to the topic of conversation. As a result, it is possible to learn English conversation more effectively by using the conversation example (200) described above rather than learning English conversation as a textbook of contents not related to oneself.

Referring to FIG. 1, the foreign language dialog system 130 may further include an additional reply DB 135 and a second alternate phrase DB 136. In this case, the foreign language dialog system 130 displays the dialog example of FIG. 4 on the learner terminals 101 and 111.

FIG. 4 shows an example dialogue with additional answers and a second replacement phrase added to the dialog example of FIG.

4, the dialogue example 400 includes a query 210, an answer 220, a first replacement phrase 230, an additional answer 410, and a portion of an additional answer 410 And a second replacement gear 420 capable of changing the second replacement gear 420. That is, the conversation example 400 of FIG. 4 further includes an additional answer 410 and a second replacement word 420 in the conversation example 200 of FIG. The query 210, the answer 220, the first replacement word 230, the additional reply 410 and the second replacement word 420 of the conversation example 400 represent a part of the entirety, The example includes more questions, answers, first replacement phrases, additional answers and second replacement phrases.

The additional answer DB 135 includes an additional answer 410 consisting of a plurality of additional answers 411 and 412 in the dialogue example 400. [ Here, answer sentences constituting plural additional answers are sentences having different contents or meanings. For example, in the first answer (411), there are four sentences, and the answer contents are different. Likewise, there are three sentences in the second answer (412). Therefore, the learner can select the most suitable sentence for the contents he wants to reply.

For example, the learner chooses "I liked to see the play on the Broadway theater" in answer # 1 (221) and answered "It was By choosing "fun and exciting." I can say, "I loved seeing a show on Broadway. It was fun and exciting." By adding these additional answers, learners will be able to give long answers rather than short answers. In addition, it is possible to reply with various contents by combining the first answer 221 and the first additional answer 411. Therefore, by dividing the conversation using the conversation example 400 of FIG. 4, a much wider variety of expressions can be learned than with the conversation example 200 of FIG.

The second replacement phrase DB 136 includes a second replacement phrase 420 consisting of additional replacement phrases 421 and 422. The first additional replacement word 421 indicates words, phrases, phrases, etc., which can change the red letters in the first additional reply (411) sentences. In FIG. 4, the parts that can be changed are displayed in red letters among the sentences of the additional answers 410. However, in addition to changing the colors, the changeable parts can be displayed to be distinguished from other parts in various ways. Here, the changeable part is displayed in bold letters.

For example, "I saw many famous paintings ." You can change the bold part of the sentence, " famous paintings, " to " rare and precious items " in one additional replacement phrase (421). In this way, by replacing the bold text part in the additional answer sentences with additional replacement words, the contents of the additional answers can be changed in detail. In addition, the learner knows which part of the sentence is changed by the additional answer sentence with the replaceable part, and knows how to change the contents through the additional replacement phrase. The learner can learn more expressions related to the conversation topic through the additional answer 410 and the second replacement phrase 420 and enjoy conversation without being bored.

Although the question answering DB 131, the first replacement word DB 132, the additional reply DB 135 and the second replacement word DB 136 are separated for convenience of explanation, these DBs may be included in one DB have.

The first controller 133 stores the questions 210 and 220 stored in the question answering DB 131, the first replacement word 230 stored in the first replacement word DB 132, The stored additional answer 410 and the second replacement word 420 stored in the second replacement word DB 136 are displayed on the learner terminals 101 and 111 as the conversation example 400 of FIG. do. Also, the first controller 133 displays the parts that can be changed into the first replacement phrases 230 among the sentences of the answer 220 to be distinguished from the remaining portions, and the second replacement phrases 420 ) Are distinguished from the rest. In this case, various methods other than the color differentiation method can be used.

The second control unit 134 may include the questions selected by the learner among the question 210, the answer 220, the first replacement word 230, the additional answer 410 and the second replacement word 420, The additional answers, and the additional replacement phrases, and displaying the learner-specific conversation examples of FIG. 5 including the selected question, the changed answer, and the changed supplementary answer on the learner terminal. Therefore, the question 210, answer 220, first replacement word 230, additional answer 410 and second replacement word 420 of the conversation example 400 can be stored in a memory , Answers, alternate phrases, additional answers, and additional replacement phrases. That is, the learner can select one sentence suitable for him in the first question 211 including two sentences, select one sentence in the first answer 221 including the five sentences, Fuji rock festival "and" Disneyland ", and one sentence can be selected from 1 answer (411) including 4 sentences. , And one additional replacement word 421 including two replacement words such as " rare and precious items " and " fun and educational ".

For example, if the learner 100 selects "Where would you recommand I visit?" Or "Did anything fun happen on the trip?" Among the questions 211, 212, I recommend the tomato festival. ", "It's not a fun memory. " to select and replace the phrase with 231, 232 among the" Disneyland "select and add among the responses (411, 412)" It was fun and exciting . "and" I was pickpocketed . "If" lost money at the casino "was selected among the additional replacement words 421, 422, (134) is configured to include questions selected by the learner, changed answers in which the changeable portion of the selected answers is replaced with the selected replacement phrases, and a modified supplementary answer A learner-to-learner conversation example 500 including the learner-specific conversation examples 500 . If the learner selects an answer sentence or an additional answer sentence that does not have a replacement or additional replacement sentence, or does not select a replacement or additional replacement sentence, the selected answer sentence or additional answer sentence is displayed without change. When the second control unit 134 displays a learner-specific conversation example in the learner terminal 101, the English sentence and the corresponding Korean sentence can be displayed together as shown in FIG. 3, and only the English sentence can be displayed have.

It should be noted here that the first additional replacement word 421 is marked as " famous paintings → rare and precious items " and " fun and exciting → fun and educational ". This is the meaning of "famous paintings" and interchangeable replacement phrase "rare and precious items" a, "fun and exciting" and is "fun and educational" interchangeable replacement phrase. Accordingly, if the learner 100 selects "I saw many famous paintings ." In the first answer 410 and selects " fun and educational " in the first additional replacement word 421, the second control unit 134 Make an error indication that you made a mistake with a sound or a letter, and make sure " fun and educational " is not selected. As noted above, " famous paintings " can not be changed to " fun and educational ".

Although the first control unit 133 and the second control unit 134 are separated from each other for convenience of explanation, the first control unit 133 and the second control unit 134 may be included in one control unit.

Thus, the learner may ask questions (210), answers (220), first alternate phrases (230), additional answers (410), and second alternate phrases (420) , Alternative phrases, additional answers, and additional replacement phrases to create your own learner-by-learner conversation example 500 as shown in FIG. In this way, if you create your own conversation example and talk to it, it is like sharing actual conversation, so learning effect is improved. In addition, you can use the additional answers and additional replacement phrases to talk about the rich and varied content of the conversation topic.

Referring to FIG. 2, there are two sentences in Question 1 (211) of the dialogue example 200, both of which ask about "whether or not they know the restaurant" or "the name of the restaurant". However, No. 1 asked "Do you know any good restaurants?" As "Do you know ~" and No. 2 as "Can you recommend a good restaurant?"
