Description

Online language learning system and method {On-line foreign language learning system and method}

The present invention relates to an online language learning system and an online language learning method. In particular, a student communicates with an instructor through a communication means such as a landline telephone, a mobile communication terminal, or a soft phone, and the instructor evaluates the conversation with the student based on the evaluation. The present invention relates to an online language learning system and an online language learning method that can enhance learning outcomes by providing a lecturer's voice explanation about a scheduled class and a student's speech error.

In language learning, the most important thing is that students naturally acquire language by having a lot of face-to-face conversations with native speakers. However, in reality, not only is there a shortage of native speakers, but it is difficult to meet face-to-face when the students and native speakers are separated from each other. Online language learning such as telephone language learning is gaining much attention. Therefore, various online language learning is commercially available, but in case of telephone language learning, the level of dialogue is maintained through direct call with the instructor, and in the case of internet language learning, the learning contents that are already provided are mechanically downloaded to the students. Stay on.

However, when online language learning is conducted only by direct conversations between the instructor and the student, the instructor takes a lot of time during the online language learning time, which causes a high labor cost for the online language learning provider, causing a high cost of tuition. . In addition, in the case of online language learning that allows a student to mechanically download the already provided learning contents, there is a problem in that learning is difficult because the learning proceeds regardless of the level of the student. In other words, as the Internet develops rapidly, many language education institutes are making efforts to provide various learning contents by using it, but students can increase their effectiveness by learning additionally by receiving their learning results reasonably. There are many things that are lacking.

In order to overcome this problem, Korean Patent No. 329343 uses English language, Japanese language, Chinese language, Korean language, etc., regardless of time and place by accessing language learning system through local area network, Internet or telephone network using personal computer or telephone. This paper provides a method for providing a language learning system using a local area network and the Internet and a telephone network that provide a method for learning with a learning effect similar to or higher than that of learning at. In this Korean patent, if the learner listens to the repeated learning by voice, the accuracy of the pronounced learning is measured in real time, which is suitable for the evaluation result using the learner's voice and the correct original sound for the part with low accuracy. The voice is spoken to the learner interactively. Here, the voice suitable for the evaluation result means that the evaluation score determined by the evaluator is converted so that the learner can hear the voice.

However, the Korean patent is not a system based on instructor talking directly with the student, but the language learning system without the instructor becomes a priority, whereby the student performs mechanical learning, and evaluation of the learning is received only as a score from the evaluator. Therefore, it is difficult not only to learn to correct the error effectively even if a student commits an error, but also has a problem that it is not suitable for a consumer who prefers a one-to-one conversation with an instructor over a class by a mechanical device.

Therefore, the problem to be solved by the present invention, after the student talks to the instructor, provides an online language learning system and online language learning method that can provide feedback to the student based on the instructor's judgment as a variety of learning other than the score It is.

Another problem to be solved by the present invention is to reduce the labor cost of language learning providers by reducing the time occupied by the instructor during the entire learning process, even if the instructor maintains the quality of learning, including the time required for 1: 1 conversation with the student. It is to provide an online language learning system and an online language learning method.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are merely provided to understand the contents of the present invention, and those skilled in the art will be able to make many modifications within the technical scope of the present invention. Therefore, the scope of the present invention should not be construed as limited to these examples.

1 is a schematic diagram of an online language learning system according to an embodiment of the present invention. Referring to FIG. 1, the online language learning system 100 includes a learning system DB 110, a service server 120, an internet network 130, a call network 140, an instructor computer terminal 150, and a system. It comprises a computer terminal 152 and the instructor call terminal 160. On the student side, the student computer terminal 170 and the student call terminal 180 are connected to the call network 140 and the internet network 130 of the online language learning system 100 to receive a class. The learning system DB 110 includes a learning management DB 112 and a course information DB 114. The course information DB 114 includes the contents of the lecture itself, such as the information of registered students, the information of the class lecturer, and the class schedule. This data is not associated with, but data is stored to enable lecture connections between students and instructors. In addition, the learning management DB 112 stores a list of lessons and contents prepared by the instructor in advance for the conversation with the student, and the instructor corrects the student's utterance error and the preparation in advance during the conversation with the student. The information of the class list selected by the instructor of the class list is stored in the learning management DB 112 by the instructor computer terminal 150 after the call between the instructor and the student. The information stored in the learning system DB 110 is inquired through a plurality of instructor computer terminals 150 and student computer terminals 170, and must be updated by the instructor computer terminal 150, so that the load required for database processing is separately considered. The DB server 122 is prepared. The DB server 122 performs processing such as storing and reading information about the learning system DB 110. In the web server 128, student member management, lecturer management, class management and the like is performed. Recording server 124 is a student and voice call through the lecturer call terminal 160 and the student call terminal 180, the student and voice recognition server 126 through the student call terminal 180 and the voice recognition server 126 The contents of the call between the DB server 122 serves to store and manage in the learning management DB (112). The instructor computer terminal 150 and the instructor call terminal 160 may be provided in a call center, such as a language school, where the instructor is waiting, or may be provided in the instructor's home. The student call terminal 180 may include all means that can be used as a telephone, such as a general fixed line telephone, a mobile communication terminal, a soft phone, a Session Initiation Protocol (SIP) phone, and the like. Accordingly, in FIG. 1, the connection between the instructor call terminal 160 and the student call terminal 180 is represented by the call network 140. The call network 140 includes a wired / wireless telephone communication network and a communication network for an Internet phone. Etc. are all included. When a call center is provided in a language school and the like, the instructor call terminal 160 is connected to the student call terminal 180 to make a call, a call exchanger server may be involved in the call network 140. Internet Protocol Private Branch Exchange (hereinafter referred to as "IPPBX") may be included. Hereinafter, for example, the call channel is formed by the IPPBX, but the call channel is not necessarily limited thereto. Meanwhile, the system computer terminal 152 connects to the web server 128 and changes or inputs data for student member management, instructor management, and class management. In FIG. 1, the system computer terminal 152 is an instructor. Like the computer terminal 150, the configuration is connected to the web server 128 by the Internet network 130, but is not necessarily limited to this, and may be directly connected to the web server 128. The instructor computer terminal 150 is connected to the web server 128 by the Internet network 130, the web server 128 allows information stored in the learning system DB 110 to be displayed on the instructor computer terminal 150, When the instructor computer terminal 150 generates a file reflecting the instructor's modifications to the utterance error of the student at the time of call learning by the voice editing program provided in the class, and the class prepared in advance in the learning management DB 112 When generating information of the class list selected by the instructor of the list, this file and the information is stored in the learning management DB (112). That is, the web server 128 allows the system computer terminal 152 or the instructor computer terminal 150 to perform instructor and student management based on the course information DB 114 and the instructor through the instructor computer terminal 150. Allow class monitoring. Here, "class monitoring" means that the instructor calls the student and creates a file reflecting the instructor's modifications to the student's utterance error during call learning or is selected by the instructor from the class list prepared in advance in the learning management DB 112. This includes generating information from the class list and preparing the student's post-call learning materials. Here, the generation of the file reflecting the instructor's modifications to the student's utterance error during the call learning by the instructor computer terminal 150 is the creation time of the recording file from the start of the call learning recording by the recording server 124. When the instructor checks the utterance error interval when there is an error such as pronunciation, grammar, vocabulary, etc. in the student's utterance during the creation of the recording file, the recording file is checked. It is possible because the instructor computer terminal 150 has a voice editing program installed in the instructor computer terminal 150 to create a voice editing file edited by inserting a file recorded by the lecturer in accordance with the speech error in the speech error section of the recording file. . The voice edit file generated as described above is stored in the learning management DB 112 by the web server 128, and the student wants to know or review the evaluation result of the student through the internet network 130. When the computer terminal 170 is connected, it can be downloaded through the web server 128. On the other hand, the voice recognition server 126 makes a call based on the information stored in the learning management DB 112 through the student call terminal 180 according to the voice recognition with the student to allow the student to proceed further learning. In the system according to the embodiment of the present invention, the DB server 122, the recording server 124, the voice recognition server 126 and the web server 128 will be referred to collectively as a service server 120.

2A and 2B are flowcharts illustrating an online language learning method according to an embodiment of the present invention, and FIGS. 3A to 3L are instructor computers at each step of performing an online language learning method according to an embodiment of the present invention. The computer screens displayed on the terminal or the student computer terminal.

[Instructor-Student Call Learning]

Figure 2a is a flow chart for explaining the overall process of the language learning in the online language learning system according to an embodiment of the present invention, Figure 2b is a voice learning server and a student learning the call (step S228) shown in Figure 2a A more detailed flow chart is shown. 1 and 2A, when the instructor accesses the instructor web page of the web server 128 through the instructor computer terminal 150, the instructor web page displays a login window (see FIG. 3A) to log in to the instructor. do. Referring to FIG. 3A, it can be seen that not only an instructor (teacher) but also an administrator are logged in to the login window, which can be mixed with the instructor computer terminal 150 of the system administrator's system computer terminal 150. Because. When the instructor logs in from the login window (step S200), the web server 128 included in the service server performs the login (step S202), and the web server 128 displays the instructor schedule screen on the instructor computer terminal 150 ( 3b) transmits and displays, and if the instructor selects the desired schedule (FIG. 3C), the instruction information screen (FIG. 3D) for the corresponding schedule is also transmitted and displayed (steps S204 and S206). Such instructor schedule screen and class information screen are stored in the learning management DB 112 or the course information DB 114 and displayed on the instructor computer terminal 150 by the web server 128 via the DB server 122. Will be. Referring to FIG. 3C, it can be seen that the instructor selected the schedule “test en (15)” from 10:00 to 10:15 on July 3, 2008. In addition, referring to Figure 3d, it can be seen that the class information screen includes the student's call number information, the lecturer's class information, and the student's attendance status information. When the instructor clicks the call button on the class information screen (see FIG. 3D) (step S208), the web server 128 allows the instructor-student to form a call channel (step S210). The call connection between the instructor and the student may be made using the IPPBX as a call exchange server, in which case, the IPPBX calls the instructor call terminal 160 to create a call channel between the IPPBX-instructor call terminals and also the IPPBX. Is made by calling the student call terminal 180 to create a call channel between the IPPBX-student. Lecturer and student information, such as the name and telephone number of the instructor and student is stored in the course information DB 114 as basic course information, the web server 128 receives such instructor and student information through the DB server 122 The instructor-student call connection is made as described above.

In the above example, the class starts from the login of the instructor, but since the checked result can be stored in the learning system DB 110 as well as the real-time reservation of the class, the instructor can view the class performance result of the student and learn the class list. Its scheduling is possible in advance via instructor computer terminal 150 or system computer terminal 152. In this case, both the instructor call terminal 160 and the student call terminal 180 reach a call signal to form a call network through ippbx, etc. at the scheduled time according to the scheduled voice learning class list, such as a wake-up call. You can also make lessons by making a call.

When the instructor-student makes a call connection, the learning content call (step S212) between the instructor call terminal 160 and the student call terminal 180 is started, and the call learning recording is started by the recording server 124 (S216). step). On the other hand, when the call learning recording is started, the lecturer computer terminal 150 is transmitted to the class monitoring information visually showing the elapsed time of the call learning recording file generated by the call learning timer 302 (step S218), the class monitoring screen (See FIG. 3E) (step S220). Referring to FIG. 3E, the class monitoring screen also displays a class list 304 and a voice recognition button 306 in addition to the call learning timer 302.

[Check speech error section and check class list]

If there is an error in the student's speech during call learning, for example, if there is a problem in pronunciation, grammar, or vocabulary, the instructor checks the speech error section. The check of the utterance error section is made by clicking the start and end points of the utterance error in the call learning timer 302 as shown in FIG. 3F. The checked utterance error interval data is uploaded to the learning management DB 112 via the DB server 122 through the web server 128. In addition, the learning system DB 110 stores learning content resources, such as pronunciation, example sentences, and follow-up, necessary for all voice learning classes, and location and material information for each learning content is classified into one unique class and indexed. The file is stored in the learning management DB 112 as a file. The class list 304 for the entire class can be checked by the instructor, and is uploaded to the learning management DB 112 through the DB server 122 through the vendor list data web server 128. At this time, it is possible to create a list of vendors for each student, group, and can also be updated to the learning management DB by entering the time the class list will be serviced. For example, if the idiom "dressed up as" is checked, as shown in Figure 3g, the unique index number for this class list is uploaded to the learning management DB (112).

The class list learning contents check and the speech error section check by the instructor (step S222) may be performed at the same time regardless of the time later, and afterwards, the speech error section check data and the checked class list learning contents may be uploaded. (Step S224).

[Voice recognition learning]

After all the call learning between the instructor and the student, the instructor clicks the voice recognition learning button 13 (step S226). Then, the call channel between the instructor-student is extinguished, and the call learning recording file made by the recording server 124 is uploaded to the learning management DB 112 through the DB server 122. At this time, the call learning timer 302 also stops working. Then, the instructor-student call connection is terminated through the IPPBX, instead, the student-voice recognition server voice recognition communication training is started according to the call connection between the student call terminal 180 and the voice recognition server 126 (step S228). The recording of the voice recognition communication chemo training is started by the recording server 124 (step S230). When the voice recognition communication training is finished, the voice recognition communication training recording file is uploaded to the learning management DB 112 through the DB server 122, and the call channel of the student-voice recognition server is destroyed by the IPPBX.

On the other hand, the voice recognition call learning step between the voice recognition server and the student (step S228) is shown in more detail in Figure 2b. Referring to FIG. 2B, a procedure (steps S300 to S308) for generating a student's learning content in the voice recognition server 126 is first performed. The course information DB 114 of the learning system DB 110 is accepted by the voice recognition server 126 to confirm the student call number (telephone number, etc.) and class number (step S300). Subsequently, the voice recognition server 126 receives the " class list checked by the instructor " stored in the learning management DB 112 in the learning system DB 110, and generates a lecture list using the voice recognition learning list as the voice recognition learning list ( Step S302). Subsequently, initializing the lecture sequence variable (step S304) and moving the lecture sequence number of the lecture list to the number of the next list (step S306) sets a plurality of class lists in a sequence and teaches a class list. When it is complete, it is intended to reacquire learning about a new class list. When the N-th lecture content is dynamically generated by this procedure (step S308), the procedure for generating the learning content is completed before proceeding by the call between the voice recognition server and the student. Subsequently, the learning contents are transmitted as voice from the voice recognition server 126 to the student call terminal 180 according to the generated learning contents (step S310). In response to the transmitted voice, the student inputs a spoken voice to the voice recognition server 126 through the student call terminal 180 (step S312). The voice recognition server 126 has a voice recognition program module built in the student's speech. Determining the success or failure of the voice recognition (S314), if successful, the voice recognition success notification sound is delivered to the student call terminal 180 (S316), in case of failure, the voice recognition failure notification sound student Transfer to the call terminal 180 to feed back (step S318). Of course, the sounds that are fed back on success and failure should be different so that the student can judge the success or failure by sound. On the other hand, the voice recognition program module built in the voice recognition server 126 is already known and widely used, a detailed description thereof will be omitted.

Such a voice recognition result is stored in the learning management DB 112 of the learning system DB 110 (step S320), and is used directly in the next learning or used as analysis data for student learning. Subsequently, it is determined whether the learning of the N-th lecture has been completed (step S322), and when learning is not completed, the voice recognition server 126 transfers the learning contents to the student call terminal 180 by voice (step S310). Is continued, and when learning is completed, data for updating whether the N-th lecture is completed is stored in the learning management DB 112 of the learning system DB 110 (step S324). After that, it is determined whether all of the lecture learning on the lecture list is completed (step S326), and if the status of all lectures has not been completed yet, the lecture sequence number of the lecture list is moved to the next list number (step S306), and all the lecture learning is completed. If so, end voice recognition.

[Voice editing]

After the voice recognition learning is completed, the instructor logs in to the web server 128 through the instructor computer terminal 150 (step S232), and performs a login on the web server 128 (step S234). Then, in step S224, the instructor computer in the opposite direction of the "voice learning recording file and speech error interval check data for voice editing" uploaded to the learning management DB 112 via the DB server 122 through the web server 128. Called to the terminal 150 (step S236; see FIG. 3H). Referring to FIG. 3H, it can be seen that the call learning recording file which is a wave file is listed up according to the upload time and stored in the learning management DB 112. The instructor selects a voice edit from the list of call learning recorded files, and loads them to the instructor computer terminal 150. "Call learning recording file and speech error section check data for voice editing" are output on the computer screen as a voice editing screen (see FIG. 3I) by a voice editing program provided in the lecturer computer terminal 150 itself. This voice editing step is also referred to as voice correction step, since the term "correction" is mainly expressed by the instructor about the content of the essay when the student is learning, such as essay writing. However, in many cases, the instructor's voice explanation is added to the call-learning recording file at the voice editing stage. However, since the voice content is rarely deleted from the call-learning recording file, the term "voice editing" is mainly used below. do. Accordingly, the voice edit file, the voice corrected file, and the speaker corrected file are terms having the same meaning. The voice edit screen shown in FIG. 3H shows the call learning recording file as a wave waveform and is displayed with overlapping speech error intervals. The instructor records the voice description of the utterance error section while viewing the voice edit screen and merges the recorded voice description file into the call learning recording file to generate a voice edit file (step S238). The voice edit file thus created is uploaded to the learning management DB 112 via the web server 128 via the DB server 122 (step S240). The voice editing program provided in the instructor computer terminal 150 in order to generate the voice editing file in the lecturer computer terminal 150 uses what is already known for editing audio files having an extension of wav, mp3, and the like. You can copy an audio file, copy it partially, delete it, insert a part of it, and mark it where you want it. Since these voice editing programs are very diverse and widely known, detailed description thereof will be omitted.

[Student listening]

After the study by the call is completed, the student accesses and logs in to the web server 128 using the student computer terminal 170 (see FIG. 3J; step S242), and performs login in the web server 128 (FIG. S244). step). When the user logs in, a learning calendar in which the student's learning schedule and learning contents are stored in the learning management DB 112 is displayed on the student computer terminal 170 (see FIG. 3K). If you click the contents of the date you want to review in the displayed learning calendar, the student downloads or streams audio files such as call learning recording files, voice recognition communication training recording files, and voice editing files that have been uploaded to the learning management DB 112. streaming) (see FIG. 3L), in operation S246. Referring to Figure 3l, it can be seen that the call learning recording file "class recording", the voice editing file is "speaking correction", the voice recognition communication learning recording file is displayed as "voice recognition learning". In addition, it can be seen that the result of performing voice recognition learning that was stored in the learning management DB 112 is displayed as "voice recognition class contents".
