2 is a diagram for explaining the lecture interpretation service of FIG. 1;
3 is a block diagram illustrating a detailed structure of the lecture interpretation service apparatus of FIG. 1, and
4 is a flowchart illustrating a driving process of a lecture interpretation service apparatus according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram illustrating a lecture interpretation service system according to an embodiment of the present invention, and FIG. 2 is a diagram illustrating the lecture interpretation service of FIG. 1.

As shown in FIG. 1, the lecture interpretation service system 90 according to the embodiment of the present invention includes the instructor terminal device 100, the learner terminal device 110, the communication network 120, and the lecture interpretation service device 130. Includes some or all.

Here, "including some or all" means that some components such as the communication network 120 are omitted, so that the terminal devices 100 and 110 and the lecture interpretation service device 130 perform direct communication (eg, P2P communication). Or, a part or all of the lecture interpretation service device 130 is integrated into a network device (for example, a wireless switching device) in the communication network 120 and can be configured, and to help a sufficient understanding of the invention Explain that it is all inclusive.

The instructor terminal device 100 includes a terminal device such as a laptop computer, a tablet PC, a smartphone, and a microphone, and includes a dedicated terminal device for providing lecture data such as a voice file for an interpretation service according to an embodiment of the present invention. Can include. Of course, the lecture data here may include signal-processed data (eg, processed data). For example, the instructor provides lecture data so that an interpreter service can be provided for his or her lecture subject through the instructor terminal device 100. To this end, the instructor may operate the instructor terminal device 100 during the lecture. For example, after running an application (hereinafter referred to as an app) at the beginning of a lecture to access the lecture interpretation service device 130, lecture interpretation so that the contents of the lecture, more precisely, an audio file for the lecture are used as lecture data. It can be provided to the service device 130.

For example, an instructor using the instructor terminal device 100 may provide the lecture data for a large amount of time in order to secure the lecture data at the beginning of the service of the lecture interpretation service device 130. Of course, the characteristics of the instructor, such as the lecture pattern, are identified through the use of the instructor's terminology, the pronunciation of the terminology, and frequently used phrases or dialogue (eg, dialect), and the lecture interpretation service device 130 If an interpretation service is provided and lecture data is increasingly secured, the quality of the service can be improved through continuous learning, such as deep learning.

For example, when a professor conducts a class in a specific subject for one semester through the teacher terminal device 100, it is provided to students from other countries, that is, international students, based on the lecture data acquired in the first month of class. Rather than providing an interpretation service, it would be better in terms of the accuracy of the interpretation service to provide an interpretation service based on data obtained for one year in the previous class. In this way, it can be seen that the instructor terminal device 100 provides lecture data suitable for the purpose of the service in order to deliver the correct content for the class of his designated subject to international students.

Of course, in the exemplary embodiment of the present invention, a professor and a learner of a university are described as an example to aid understanding of the description, but various applications may be applied. For example, even when dealing with foreign buyers who meet frequently for work, conducting intermittent workshops with overseas agents, or conducting academic seminars at academic conferences abroad, In this case, an interpreter service can be provided based on the identification of the person's language-speaking style. Therefore, in the embodiment of the present invention, the service will not be specifically limited to learning. For example, even if it is not the teacher's terminal device 100, a nearby microphone installed in an auditorium or the like may be used to acquire a person's voice.

The learner terminal device 110 includes various devices capable of providing an interpretation service. Like the instructor terminal device 100, it may further include a laptop computer, a tablet PC, a smart phone, and an artificial intelligence (AI) speaker interlocking with the corresponding devices. Of course, it may further include a dedicated terminal providing an interpretation service. For example, international students studying abroad in other countries may use the learner terminal device 110 as an interpreter in order to participate in a class in a major subject. To this end, the learner terminal device 110 may be released with a program according to an embodiment of the present invention as a default when the product is shipped, or access the lecture interpretation service device 130 to download and execute an app. have.

The learner terminal device 110 may provide an interpreter service for a teacher in a class of a specific subject according to the execution of the app, for example. Of course, the learner terminal device 110 may access the lecture interpretation service device 130 to provide a service through streaming, but an interpretation service may be provided through a program in the learner terminal device 110. It can be set in various ways according to the intention of the system designer. For example, resources (eg, HW, SW resources) of the learner terminal device 110 may have lower performance than the lecture interpretation service device 130. Therefore, it is preferable to be performed in the lecture interpretation service device 130 for accurate and rapid data processing. On the other hand, when the communication network 120 is temporarily turned off or a load occurs, the service may be stopped. Accordingly, in this case, the service operation subject may be changed according to the state of the communication network 120. Since various designs are possible as described above, the embodiment of the present invention will not be particularly limited to any one method.

When requesting the interpreter service, the learner can enter the lecture subject or basic information about the instructor, but upon execution of the app, the learner terminal device 110 automatically receives the instructor's voice through the microphone and then receives the received voice. It is also possible to analyze the information and determine the instructor based on the analysis result and provide an interpreter service immediately. In addition, it is also possible to determine what subjects are being taught by collecting and analyzing the contents of the initial lecture. As described above, since there may be various ways of performing an interpretation service by recognizing an instructor in a specific subject, for example, if the instructor is judged, it is possible to ask the learner for a selection based on this. Therefore, the embodiment of the present invention will not be specifically limited to any one method.

The lecture voice of the instructor collected through the microphone of the learner terminal device 110 is interpreted through an interpreter program and output to a voice output unit such as a speaker of the learner terminal device 110. Of course, the audio output unit may be a speaker, but includes a user interface, that is, a connection unit for connecting jacks such as earphones or headphones. In addition, the learner terminal device 110 transmits the instructor's voice signal received during class time through the app to the lecture interpretation service device 130 in real time, even if it does not include a separate interpretation program, and provides an interpretation service through this. Since it is possible to receive any number, the embodiment of the present invention will not be particularly limited to any one method.

The communication network 120 includes all wired and wireless communication networks. For example, as the communication network 120, a wired or wireless Internet network may be used or interlocked. Here, the wired network includes an Internet network such as a cable network or a public telephone network (PSTN), and the wireless communication network includes CDMA, WCDMA, GSM, Evolved Packet Core (EPC), Long Term Evolution (LTE), and Wibro networks. It is meant to include. Of course, the communication network 120 according to the embodiment of the present invention is not limited thereto, and may be used as an access network for a next-generation mobile communication system to be implemented in the future, for example, a cloud computing network or a 5G network under a cloud computing environment. For example, when the communication network 120 is a wired communication network, the access point in the communication network 120 can be connected to the switching center of the telephone office, but in the case of a wireless communication network, data is accessed by accessing SGSN or GGSN (Gateway GPRS Support Node) operated by the communication company Alternatively, data can be processed by accessing various repeaters such as BTS (Base Station Transmission), NodeB, and e-NodeB.

The communication network 120 may include an access point. Here, the access point includes a small base station such as a femto or pico base station that is frequently installed in a building. Here, the femto or pico base station is classified according to how many terminal devices 100 and 110 can be connected to the maximum according to the classification of the small base station. Of course, the access point includes a short-range communication module for performing short-range communication such as ZigBee and Wi-Fi with the terminal devices 100 and 110. The access point may use TCP/IP or Real-Time Streaming Protocol (RTSP) for wireless communication. Here, short-range communication may be performed in various standards such as Bluetooth, Zigbee, infrared, radio frequency (RF) such as ultra high frequency (UHF) and very high frequency (VHF), and ultra wideband communication (UWB) in addition to Wi-Fi. Accordingly, the access point may extract the location of the data packet, designate the best communication path for the extracted location, and deliver the data packet to the next device, for example, the lecture interpretation service device 130 along the designated communication path. The access point can share several lines in a general network environment, and includes, for example, a router, a repeater, and a repeater.

The lecture interpretation service device 130 provides a user-based interpretation service. Here, the "user-based" may refer to a lecture or a celebrity. In this case, it can be used more usefully. In addition to the lecture interpretation service device 130, FIG. 1 describes the collection of lecture data for interpretation service through the instructor terminal device 100, taking a university as an example. However, in the case of celebrities, lectures through lecture images made in the past are described. By collecting data, it is also possible to identify the lecture pattern or style of the relevant celebrity or instructor, and provide interpretation services based on this.

For example, as can be seen in FIG. 2, the lecture interpretation service device 130 separates and stores lecture data for each instructor A, B, and C, and for each subject of the corresponding instructor on the DB 130a. Lecture interpretation service can be provided based on lecture data. As mentioned above, in order to provide an interpretation service, the lecture interpretation service device 130 collects and stores data on an object to be interpreted in various ways, and then provides an interpretation service based on this, thereby reducing errors in interpretation. There will be.

In other words, if there is a designation of the subject a of the instructor A of FIG. 2 from the learner terminal device 110 of FIG. 1, or when this is recognized through voice recognition, the lecture interpretation service device 130 transmits the corresponding information. Provide interpreter services on the basis of. For example, after obtaining data for interpretation of a specific class by learning technical terms, pronunciation of technical terms, frequently used phrases and conversational styles according to the subject of professors in major engineering departments, learners when conducting lectures on specific subjects It is connected to the terminal device 110 to interpret the contents of a lecture in real time by combining a learning module of a specific subject previously learned, for example, with an existing interpretation module. As a result, international students will be able to improve their understanding of technical terms and explanations of specific professors.

As mentioned above, the lecture interpretation service device 130 does not collect data or data for generating lecture data only through the instructor terminal device 100, but provides a lecture by a specific person through various videos registered in the search portal. The accuracy of interpretation can be improved by providing user-based interpretation services by identifying patterns or styles, creating big data through various paths, and performing deep learning operations using the generated big data. . For example, even if there is an interpretation error in some parts, the error is corrected through deep learning so that the error does not occur in the future, so that the accuracy of the interpretation is improved so that foreign students or celebrity lecturers can read the lecture contents of a specific person. It can help you understand correctly.

Since recent speech recognition technology reaches to the technology of grasping sentences through corpus and processing language at the level of natural language in this way, a higher quality interpretation service is provided by reflecting characteristics for each user (e.g., instructor). You will be able to do it. Words spoken may vary from person to person according to their intellectual standard, and even if they utter the same word or sentence, there is always a slight difference, such as the local color may be reflected and dialect. In this way, the lecture interpretation service apparatus 130 determines language proficiency that is subtly different for each user, converts the data into a DB in the DB 130a, and provides a service based on this. For example, the word "content" frequently spoken by a specific user may be recorded in the category of the word "content" of the DB 130a, and an interpreter service may be performed based on this.

3 is a block diagram illustrating a detailed structure of the lecture interpretation service apparatus of FIG. 1.

For convenience of explanation, referring to FIG. 3 together with FIG. 1, the lecture interpretation service apparatus 130 according to the embodiment of the present invention includes a communication interface unit 300, a control unit 310, a user-based interpretation processing unit 320, and a storage unit. Including some or all of (330).

Here, "including some or all" means that some components such as the storage unit 330 are omitted, or some components such as the user-based interpretation processing unit 320 are other components such as the control unit 310 It is intended to mean something that can be integrated and configured in, and will be described as including all in order to help a sufficient understanding of the invention.

The communication interface unit 300 communicates with the instructor terminal device 100 and the learner terminal device 110 via the communication network 120 of FIG. 1. In a process of performing communication, the communication interface unit 300 may further perform various operations such as modulation/demodulation, encoding/decoding, muxing/demuxing, scaling, encryption/decryption, and the like. This is obvious to those skilled in the art, so further description will be omitted. However, scaling may include a speech processing operation such as removing or amplifying noise of the speech signal.

The communication interface unit 300 may perform communication with the instructor's terminal device 100 under the control of the controller 310 to receive and transmit a voice file recording the contents of the instructor's lecture. In addition, even if it is not the instructor terminal device 100, the communication interface unit 300 communicates with an external device to obtain a related video to the controller 310 when there is a recorded video of the instructor on the search portal site. I can deliver. The recorded video will contain additional information about the teacher's name and affiliation, so this is to be used.

Furthermore, the communication interface unit 300 may provide an app for an interpretation service or an interpretation service according to the execution of the app when there is a request from the learner terminal device 110. For example, when the app for interpretation service is executed, the learner terminal device 110 may automatically turn on a microphone to obtain a voice for a teacher's class in a classroom. And, by transmitting the acquired voice signal to the lecture interpretation service apparatus 130 of FIG. 1, the communication interface unit 300 may receive it.

In addition, the communication interface unit 300 transmits the interpretation service provided by the user-based interpretation processing unit 320 to the learner terminal device 110 under the control of the control unit 310, thereby interpreting through the voice output unit of the learner terminal device 110. To be provided. Of course, the interpretation service here can be regarded as an interpretation service provided based on the instructor's lecture data, more precisely, the instructor's verbal pattern or speech pattern.

The control unit 310 is in charge of overall control operations of the communication interface unit 300, the user-based interpretation processing unit 320, and the storage unit 330 constituting the lecture interpretation service apparatus 130. For example, the control unit 310 executes the user-based interpretation processing unit 320 to provide an interpretation service via the communication network 120 of FIG. 1. For example, when a voice recognition result is provided through an app of the learner's terminal device 110, a designated instructor is determined based on this, and an interpretation service is provided based on data matching the instructor.

The controller 310 may temporarily store various pieces of information or data processed in the process of performing the interpretation service in the storage unit 330 and then provide it to the user-based interpretation processing unit 320. For example, when there is a request for a service from a plurality of learners, the query is temporarily stored in the storage unit 330 and then the interpretation service is sequentially performed.

Meanwhile, the control unit 310 of FIG. 3 may include a CPU and a memory as another embodiment of the present invention. The CPU and memory can be formed in one chip. Here, the CPU includes a control circuit, an operation unit (ALU), an instruction analysis unit, and a registry, and the memory may include RAM. The control circuit is in charge of the control operation, the operation unit calculates binary bit information, and the instruction analysis unit is responsible for interpreting the machine language so that the control circuit can recognize it, for example, converting high-level language to machine language, and registry Is involved in software data storage. The software related to the instruction analysis unit may largely include a high-level language program, a program that converts a high-level language into a machine language (eg, interpreter, compiler, etc.), and a machine language program, and the CPU can interlock with the corresponding programs. The CPU may copy a program stored in the user-based interpretation processing unit 320 of FIG. 3 at the initial stage of operation of the system, load it into a memory, and execute it, thereby rapidly increasing data processing speed.

The user-based interpretation processing unit 320 may execute a program for interpretation service, such as an app, to proceed with the service, and also proceeds the interpretation service of a designated instructor or a specific person through information provided from the learner terminal device 110. Of course, the received information may be information directly selected and provided by the learner or a result of speech recognition. Therefore, the user-based interpretation processing unit 320 provides an interpretation service specialized to a specific person. For example, the voice signal of a specific professor at a Korean university may be analyzed to provide an interpretation service in consideration of the characteristics of the corresponding professor, and in the case of Korean, an interpretation service in English may be provided. Of course, such a transformed language may be possible by the learner's choice.

For example, the user-based interpretation processing unit 320 analyzes the lecture data or language proficiency pattern of a specific instructor, and if the specific terminology is frequently used or the dialect is spoken a lot, the data on this is already secured. It finds the correct word as a basis and provides an interpretation service based on it. Of course, since this provides an interpretation service based on the big data secured by continuously collecting data for a specific person, the accuracy is increased accordingly.

When a voice signal of a specific person is received, the user-based interpretation processing unit 320 may perform an operation of recognizing it. After recognizing the speech signal, the recognition result is converted into text, and in the process, sentence-based, for example, sentences may include short sentences, Chinese sentences, complex sentences, and mixed sentences. These sentences are converted into text, and the text converted sentence is The DB 130a searches for a selected language matching it, converts it into voice, and provides it to the learner terminal device 110. For example, when providing an interpretation service for the sentence "I will look at dentures in this lecture", the voice signal is analyzed, and of course, if the text is provided with the voice, the voice signal is not separated, Although the text can be used directly, it may be possible to use it because information on subtitles is provided in the case of normal TV broadcasting. However, in the embodiment of the present invention, since the interpretation is performed directly in the field rather than in this situation, the voice signal is received and received. A Korean sentence is determined by analyzing an audio signal, and the textualized sentence is searched again from the DB 130a to find a language such as English matching the sentence. Thereafter, the voice signal of the corresponding language or the Korean sentence is directly converted into an English sentence, and the voice signal of the converted English sentence is transmitted to the learner terminal device 110.

The storage unit 330 stores various information or data processed under the control of the controller 310. If the information is a simple control command or a response command, the data may mean a voice signal such as a voice file containing actual information. When the additional information is transmitted by including real data in the data format, it may be separated by a multiplexer and stored in the storage unit 330 under the control of the controller 310. In addition, the separated real voice signal may be provided to the user-based interpretation processing unit 320 to provide an interpretation service according to a recognition result.
