System for Providing Learning Contents through User Word Search History {System For Providing Educational Contents}

The present invention relates to a system for providing learning contents through a user's word search history, and more particularly, a word search using a mobile device having a function of an electronic dictionary, and a list of a user's search history, that is, a list of learning history data. The present invention relates to a learning content providing system for generating learning contents using the contents and allowing the user to perform phonological training through the contents.

The present invention relates to a method and apparatus for providing voice training data in a portable electronic dictionary system, and more particularly, a user searches an electronic dictionary, stores the history of the search as data, and analyzes or processes the data. It is about creating a list according to the level of learning of the students, generating materials such as MP3s according to the list, and providing the repetitive training of the voice.

In the present invention, in providing voice training data to a user, it is distributed in a portable electronic dictionary system, or synchronized with a PC or a server or the like to provide a better sound quality and learning analysis than a portable system through high performance computing. Information can be processed, the user can not only report his / her own learning level by searching the dictionary, but also create his / her own learning materials. It is about how to configure a device or platform that can be created and provided together.

The present invention relates to an electronic dictionary, and a method and apparatus for providing a user's personalized content through a data history of a word searched by a user.

With the development of cerebral physiology and behavioral psychology, language learning has shifted from document reading to phonological learning, and as the trend of audio-language approach, ie, speech-language-oriented language learning, becomes the center of learning, It adds a function that enables the electronic dictionary centered on the existing search result generation to help voice training. The background technology is the aspect of oriented programming, which is a recent program trend. This is called 'search', which is an important basis for knowing the level of learning of the user, how to record it, analyze it, and generate training data.

Basically, electronic dictionaries have superior portability compared to paper dictionaries, shorten the search time, have the advantage of storing a lot of vocabulary, TTS (Text to speech) engine technology, or PCM ( Pulse code modulation (Pulse Code Modulation) playback method provides the voice of words when searching for the user, and provides the user's search history collectively known as history.

However, in order to conduct voice training, which is an important learning area in the latest speech language learning theory, based on the development of behavioral psychology and cerebral physiology, such as audio lingual approach and Mim-mem theory, the search of existing electronic dictionary It is necessary to use an interface that provides one word of voice every hour, and it is not linked with the history function. To train only the voice of words for a long time, press the button several times to repeat the voice of one word, and then search for another word. Listening to voice information was a hassle to immerse themselves in voice training.

The search history of the electronic dictionary, commonly referred to as the history function, is an important information that can be used to learn the user's learning level and can be used for future learning. By leaving only a number of retrieval histories, the information creation logic is simple and stored as not enough data to analyze and provide visual, relevance, etc., so it is necessary to re-search rather than provide learning progress or use of voice training. The purpose is to reduce the key input in the case. In addition, the number of words in the history of the existing electronic dictionary is limited to about 100-200, most of them are.

In addition, the Hangman game provided in portable electronic dictionaries can be viewed as customized content according to the user's history, and most of the games supported by most electronic dictionaries, or the user inserts random spelling The spelling is posted when spelling is posted, and if it is not spelled, the game is punishable by completing the line forming the gallows step by step. The core purpose of the spelling is to match the spelling alphabet. Although there is a similarity of customized learning contents in that it provides learning contents using the history, it is provided in the form of a game, such as whether or not a voice is provided. can do.

The present invention provides content similar to the language training content of an audiobook, which is in the form of a cassette tape, CD (CD), MP3 (mp3), etc. Recently, it is mainly used in vehicles for people who do not have time to read a book, and it is used as an effective teaching material for voice learning of foreign languages, and there are language learning contents such as vocabulary and pronunciation training, but it is popular content. Efficient learning has been difficult, such as the fact that one word is duplicated or the individual learning experience is missing.

Background Art In the present invention, the TTS engine program is a program that automatically reads characters, synthesizes phonemes of each language corresponding to the characters of the corresponding language, and is used for converting an e-book in a sentence unit into voice. .

Taken together, conventionally, when using a portable electronic dictionary and TTS (Text To Speech) program on a PC, the history of the electronic dictionary is written down by itself, and according to the language logic of the TTS engine, there are a list of several words. Edit the document file with punctuation marks such as periods, commas, and quotes to separate the phonograms of each word, convert the document back into a voice file through the TTS engine, and save it back to the mp3 player. To use the voice training content, there was a very troublesome use.

The present invention, which is devised to solve the above problems, stored in the learning history of the device so that the user uses the words that he or she is searching and learning in the electronic dictionary as valid content, such as his own voice training materials The main purpose is to use the word list to easily provide voice content for learning without moving, copying, copying, and copying. In case of distributing modules such as list, user history, voice generation, etc. by using distributed system method on PC and server with high performance, data such as the number of repetition of playback of voice content used in this learning is stored in the device as history. By applying the computing power of higher performance than the electronic device through the means such as, It is possible to grasp the learning degree of a user, to provide a variety of learning methods, for example, it is possible to provide a way to analyze the learning degree of each word, and to learn later without missing, By analyzing the user's search history in the long term, it is possible to create and apply contents corresponding to various phonological learning techniques such as Mim-mem and verbal behavior psychology, and the PC / or server uses high quality tts engines. Through the provided characteristics, it provides a system for providing learning contents through the user's word search history, which constitutes a platform that can provide multimedia customized contents with high phonological learning effect compared to the existing portable electronic dictionary single system.

More specifically, there are two embodiments according to the present invention, which provides voice training data in an electronic dictionary (mobile device) and provides voice training data in connection with a learning content providing server platform.

As an example of implementing an electronic dictionary (mobile device) as its own system, a representative example of creating a user search history DB in an electronic dictionary and sequentially reproducing the word data list of the DB in a TTS engine mounted in the electronic dictionary For example, in the case of a multi-function portable electronic dictionary with an electronic dictionary and a multimedia function, the PCT (Pulse Code Modulation) voice data is generated by the TTS engine, and the voice data is transmitted to an MP3 player or the like for example. Preferred as an embodiment of.

A portable electronic dictionary system and a learning content providing server (PC / server) platform linked to an electronic dictionary allow a user to search for a word, and the search history is stored in a DB slot or a file of the electronic dictionary. When a sequence of two or more words in a sequence exceeds a single word, various multimedia learning content data are sequentially and repeatedly provided.

In detail, the preferred solution of the present invention, in a mobile device providing an electronic dictionary function, to log a list of recently searched words, and to create and store a list of words or a specific number of days or a specific number of words ( Step a) and step (b) of adjusting the number of repetitions of this word, constructing a list of announcements for the training method, etc. to form a list that can be reproduced or generated as a voice file, and repeating words and insertions. (C) the user generating the voice by mixing the PCM data of the training guide and the instruction to guide the learning; and (d) the user playing the voice of the step (c); (E) preferably records and analyzes the learning habits and achievements by recording the frequency of play, stop, and playing time.If the platform is not configured, step (e) It can be configured to omit.

In step (a), a method of creating a list of words is to create a search history DB and list newly found words in sequential or non-sequential order. Alternatively, a word-by-word search is performed on the whole word db. It is configured to store the number of times for each field of the word, and when the user searches, the number of search is added to the field and stored, and a new search word list is calculated by analyzing the existing field. In addition, various examples of generating lists such as filtering the list by level by comparing the list with DB fields that store the level information of words may be exemplified.

In step (b), when the word list is extracted in step 1, "pronounce by following the sound you hear. You don't have to think." The list and time of the announcements are arranged by the voice of the announcement or the tts engine, and the list and the order of the contents to be played together with the word list are finally created. At this time, when synthesizing the sound of the TTS (Text to Speach) engine and the natural voice of the PCM (Pulse Code Modulation) according to the performance and specification of the device, the tts playback part and the multimedia playback part are combined in the form of a timeline or a playlist. Fill out the data and save it. In the case of an electronic dictionary supporting various tts including the mother tongue, this step may be composed by simply creating a list of voices generated only by the operation sequence of the TTS, and defining the length and repetition frequency of the voice information of the word to be played. Due to the nature of this process, it is desirable to be able to specify the number of repetitions of one word, the number of repetitions of the entire reproduction, and the like.

In summary, in the electronic dictionary, the search history data itself or two or more word arrays according to the user's learning progress are converted into voices, and in this process, technologies such as playlist, file generation, and voice synthesis are used. It is desirable to be able to provide it to the user.

In the case of configuring step (b) by synchronizing the search history generated in step (a) with the learning content providing server (PC or server), the TTS engine of high quality is compared with the case of providing content directly from a mobile device. Can be used, and there are various ways to analyze the level of users.

In step (c), the voice is actually generated and played according to the playlist created in step 2 or the playback timeline logic, which is provided as an MP3 file or a TTS engine can be operated in real time. In some cases.

In addition, background music or PCM voice for announcements, which are prepared in advance in the announcement DB, can be inserted into the playback order.In case of providing an audio file such as MP3, the file is automatically naming and the announcement is played. Inserting the list in the middle of the list is preferable, or mixing and editing the PCM is provided as a single file. When configuring the step (c) in the PC or server linked with the electronic dictionary, in the step (d), the user reproduces the list generated in the step (c) in real time with a TTS engine or as a file such as an MP3.

In the step (e), in order to measure the amount and degree of learning of the user, the user stores information on operating the device, and the operation information includes the number of playbacks, the number of pauses during playback, the number of pauses during playback, and playback. It is preferable to include the repeated words among the words, and the word searched by the user corresponds to the word difficulty information included in the db information of the electronic dictionary, or generally the commentary text information of the word, ie, beginner, intermediate, and advanced words. It is preferable to configure this step as a process of determining the user's word search level and reporting it to the user, and comparing the word level information db of the word with the user's searched word (b) Comprising a step, to form a list by deleting the words provided in the existing learning content, it can be said that the preferred configuration of the present invention.

The present invention provides a playlist and voice data for repetitive voice training to the user by using the search history, which is an important data that can distinguish the learning scale of the user, so that the user can easily learn words with his or her own voice content. To help. In addition, it collects information on voice playback, analyzes the user's word learning situation through the reporting process, secures data that can help future learning, and increases the utilization of the voice content provided to the user. Can help progress.

In addition to providing a high effect in response to the latest learning theory through repeated voices, it also has an attachment effect on learning materials prepared based on the materials created by the user. Occurs. Part of the process of the present invention, that is, a word list with a user manually processed on a PC to generate a voice file, it can be increased when compared to the case of copying to an mp3 player or the like.
