In addition, recording information (l) indicating whether the learner has recorded the file for each file, and the address (m) where the file recorded by the learner is located are also included.

In the case of a word, the type sequence number (c) becomes a serial sequence number of a new word or idiom in the learning unit, and in the case of a conversation, it becomes the serial number of an independent conversation situation in the learning unit, and a sentence for listening. Is the serial number of the paragraph provided by a unit of learning. If the learning content is a word or idiom, the serial number (d) for each type is a serial number of an example sentence, a synonym, or a derivative word including each word or idiom, and a sentence used in an independent conversation situation when the learning content is a conversation. When the learning content is a sentence for listening, it indicates the serial number of the individual sentence included in each paragraph. The serial number (d) for each sentence may be given detailed attribute information for each structural semantic unit of the sentence.

FIG. 5 is an explanatory diagram for classifying language learning contents learned by a portable digital language learning apparatus according to an embodiment of the present invention, and FIG. 6 is a data management table configured according to the language learning contents classified by FIG. DMT) is an example of a field value.

As shown in FIG. 5, as an example of the structure of the learning contents, the learning contents of the first unit of the learning unit are the words and idioms to be learned in the lesson, type 1, the general conversation, the type 2, and the news listening. The sentence for listening learning such as Of course, the content of learning and the order of composition can be changed, but it is possible to classify by type according to learning content.

At this time, the attribute value of the memory management table for each learning type is as shown in FIG. In the case of Type 1, each of the four separate voice files and the text file: ① celebrate, ② celebrate, ③ people celebrated him for his glorious victory, ④ people celebrated his glorious victory ”. 330, and has attribute values as described in lines 1 to 4 of FIG. In case of Type 2, four independent voice files 『⑤ A: You look like a million bucks, ⑥ B: That's very nice of you to say so, ⑦ A: Do you exercise everyday ?, ⑧ B: I try to』 And a text file, and four voice files and text files translated therefrom are stored in the data storage unit 300 of the memory, and include attribute values for distinguishing each speaker, attribute values indicating a conversation order, and the like. It has an attribute value from 9 to 12 lines. For Type 3, 『⑨ Ladies and gentlemen, welcome abroad Flight 007 bound for Paris, ⑩ I'm your pilot, Gregory Peck, ⑪ We'll be flying at an altitude of 19,000 feet and should arrive in Paris at 9:20 after a brief stopover in London, ⑫ We hope you'll have an enjoyable flight ”and four independent voice and text files translated therein are stored in the data storage unit 330 of the memory. It has attribute values as described in lines 13 to 16 of FIG. 6 including the attribute values for the order of each sentence.

In particular, in the case where the learner pronounces the voice file, recording information (l) indicating whether the learner recorded the file corresponding to the data management table 330 and the recorded address (m) are recorded.

Hereinafter, the operation of the language learner according to an embodiment of the present invention having the memory 300 having the logical structure as described above will be described with reference to the flowchart of FIG. 7. In particular, in the description, the setting of variables for performing a command, for example, time setting, section setting, learning type setting, etc., may be changed by a combination of buttons displayed on the input unit 100. Since this is possible and well known to those skilled in the art, the detailed description is omitted.

7 is a flowchart for explaining the basic playback operation of FIG. When power is applied to the device and the set button 115 on the input unit 10 is pressed, a menu for each learning type is displayed on the screen. Select a type to learn using a separate move key or the set button (115). If the play / pause button 110 is selected after selecting the learning content, the k value of FIG. 7 corresponding to the selected learning content is set to play or display the voice and / or text file in the order of FIG. 7. At this time, if the marking information is recorded in the DMT value of the specific learning content, the learning content of the next sequence is reproduced without reproducing. In addition, if it is not necessary to relearn the learning contents currently being reproduced, the mark button 112 is pressed. At this time, the microprocessor 210 inverts the current state of the mark attribute of the DMT corresponding to the voice file being reproduced the moment the current mark button is pressed. The audio file whose mark attribute is reversed is not played back. If you want to reverse the inverted state, you can restore the original state by using the Set button or other command buttons.

In addition, the learner may use the speed adjusting button 114 to speed up or slow down the speed of playing back the voice file stored in the memory.

In addition, when the interval repeat 113 is specified, the interval repeat button is pressed, the search backward (111b) button is pressed to the desired position, the setting button 115 is set by pressing the start section, and the forward search (111a). After pressing the () button to find the file to be repeated, press the setting button 115 again to set the end section, and press the set button to set the number of repetitions. When the setting is completed, repeat playback is performed using the section repeat 113 command. Therefore, when the section to be repeated is set, the repeat playback can be performed immediately by the section repeat 113 command.

On the other hand, the automatic repeat (113a), follow the pronunciation 116, follow the recording (117), pronunciation role 118, recording role 119 command operates differently depending on the learning type. The function is explained by dividing by learning type as follows.

First, when the auto repeat 113a button is pressed, the voice and text file currently being played is infinitely repeated until the auto repeat 113a button is pressed again. That is, when the learning content corresponding to Type 1 is being reproduced, a function of automatically repeating the entirety including interpretations and sentences corresponding to a word or idiom is performed. That is, in the type 1 of Fig. 5, the voice and text files corresponding to ① + ② + ③ + ④ are continuously output and repeat indefinitely. When the content corresponding to Type 2 is being played, the currently playing sentence is repeated indefinitely when the automatic repeat 113a button is pressed. That is, in the type 2 of FIG. 5, if the automatic repeat 113a button is pressed while the current ⑦ is being played, the sentence of ⑦ is repeated indefinitely and if the automatic repeat 113a button is pressed again, the normal playback state is returned to the number ⑧. The sentence is played. However, for type 3, the autorepeat function is slightly different. If the Auto Repeat button is pressed while a sentence is currently being played, the audio file is played back for a preset time interval (for example: 4 seconds) based on the moment when the button is pressed. The voice file is played indefinitely with the end position of the voice file corresponding to the moment when the button is pressed (that is, during the time interval of 4 seconds). At this time, if the auto repeat button is pressed again, the subsequent part is played continuously. The time setting of the file corresponding to type 3 can be done by using a set button or another command input button.

On the other hand, when the follow-on pronunciation button 116 is pressed, in the case of Type 1, when sentence 3 of FIG. 5 is being played, playback is stopped for the time required for the playback of sentence ③ after the sentence ③ has been played and then the next sequence. Audio file is played. The learner pronounces the pronunciation of the previously played contents during the time when the reproduction is stopped and performs the pronunciation training. If the follow-on button 116 is pressed at the moment when sentence ② is played, the above function is performed on sentence ②. In the case of type 2, the pronunciation-following function is performed by listening in one sentence. When the follow sentence 116 button is pressed while the sentence 5 in Fig. 5 is being played back, the audio file is played in the next order after playback is stopped for the time required to play the sentence 5 after the sentence 5 is played. The learner pronounces the pronunciation of the previously played contents during the time when the reproduction is stopped and performs the pronunciation training. However, in the case of type 3, instead of stopping the playback time to follow the pronunciation in units of sentences, as in the case of the automatic repetition, the time interval set in advance based on the moment when the button to follow the pronunciation 116 is pressed (for example, (4 seconds), the audio file played back is played back, and the file is played repeatedly from the position of the voice file corresponding to the moment when the button is pressed as the end point (i.e. for 4 seconds). After playback is stopped for a time interval, the next audio file is played. The learner pronounces the pronunciation of the previously played contents during the time when the reproduction is stopped and performs the pronunciation training. In this case, you can also train the pronunciation by specifying the number of repetitions. The pronunciation-following function can provide an effective language learning function that can compare not only native speakers and their pronunciation but also speaking speed.

In addition, the recording follow function 117 is an automatic recording function and an automatic playback function added to the pronunciation follow function. In other words, when the follow recording button 117 is pressed, if the sentence ③ is being played in the case of type 1, the playback is stopped for the time required for the playback of the sentence ③ after the reproduction of the sentence ③ is completed and the learner is pronounced instead. The sentence to be recorded is automatically recorded for the time required to play the sentence ③. After recording, a sentence ③ pronounced by the native speaker is automatically played, and then the voice file recorded by the learner is played. Therefore, by comparing the pronunciation of the native speaker and the pronunciation of the learner provides a function that allows the learner to correct their pronunciation. When the sentence of type 2 is being reproduced, the same function is performed in units of sentences, and when the sentence of type 3 is being reproduced, it is automatically recorded and automatically reproduced against a predetermined time.

Next, a special function of the set 115 button will be described. For Type 1 learning, when the Set 115 button is pressed, an example sentence and example interpretation (④) including a heading word or idiom (①), a description thereof (②), and a heading word or sentence (③) are played. It is a function to change various configurations. In the basic playback mode, the audio files are played in the order of saving them, that is, in the order of ① + ② + ③ + ④, but press the Set 115 button once, then press ① + ④ again, ① + ② again, and press ② + again. As shown in (1), the contents and the order of playback can be configured differently. Finally, all contents originally stored are reduced in the order of reproduction. In addition, the combination of the contents to be reproduced can be variously changed as needed. For type 2 learning content, the setting button performs a function of selecting a role in the role function described below. That is, in the type 2 sentence of FIG. 5, the user has a role to pronounce, that is, a speaker A or B that is not played. If the command to perform the role is executed, it basically plays the role of the speaker of the second sentence to be played, but when the set button is pressed, the next speaker is selected, and the second button is pressed to select the other speaker. Is reduced to the default speaker selection mode. For type 3 learning content, the setting button functions to set a constant time back from the autorepeat function and the follow function. That is, the preset time (for example, 4 seconds, 8 seconds, 12 seconds, 16 seconds) can be selected by repeatedly pressing the set 115 button.

Next, the pronunciation role 118 and the recording role 119 will be described. Role functions are only valid for Type 2 learning content. When the pronunciation role 118 button is pressed, since the role is set to the basic role setting, the learner plays the sentence ⑤ and the next sentence ⑦ is stopped after the play of the sentence ⑥ is stopped for the time required to play the next sentence ⑥. Is played. Learner pronounces sentence ⑥ during the time when sentence ⑥ is not played and learns conversation.

When the recording role (119) button is pressed, the learner is set to the basic setting, so that the sentence ⑥ is stopped by the time required to play the sentence ⑤ first, and then the sentence ⑥ and the sentence pronounced by the learner instead. ⑥ is stored. Next, the sentence ⑦ is reproduced and the sentence ⑧ pronounced by the learner is stored. When the reproduction of the conversation about a specific situation is finished, the entire situation is automatically reproduced. At this time, the learner plays the specific conversation role and reproduces the pronunciation. In other words, you can automatically learn conversational and pronunciation learning for a specific situation.
