Description

CD language learner with repeat and dialogue

The present invention relates to a language learner using a compact disc (CD), and more particularly to a language learner having an improved repeating function and a dialogue function.

With increasing interest in language learning, many kinds of devices for language learning have been developed. In the past, language learners using magnetic tapes were commonly used, but such learners deteriorate sound quality when used for a long time, and have a very inconvenient disadvantage in that they cannot listen intensively.

In order to improve the disadvantages of the magnetic tape, CD, which is widely used for music, can be used as a language learning medium, capable of random access and less deterioration of sound quality. 2 is a view for explaining how data is stored in a CD. As can be seen in FIG. 2, the area in which data is stored in the CD is divided into three areas: a table of content (TOC) area 1, a data area 2 and a lead out area 3. FIG. The data area 2 is an area in which data to be actually stored, for example, music data, foreign language learning voice data, and the like, is divided into a track and an index. The data area may generally contain up to 99 tracks and each track may contain up to 99 indexes. The track and the index become units that can be randomly accessed. In the CD, the TOC area 1 inside the data area 2 is an area containing positional information about the data written in the data area 2. That is, it is possible to randomly access the data area 2 by referring to this area as an area for storing information on each track and index. The lead out area 3 is an area for storing the management number and the like of the CD maker irrelevant to the user.

Such CDs have been used mainly for music until now, and thus, CD playback devices up to now have been mainly produced for music reproduction. However, in order to maximize the effect of the language learner, a variety of functions that are not required in the apparatus for playing music are required.

Accordingly, it is an object of the present invention to provide an improved repetition function that can proceed while repeating each sentence a desired number of times in a language learner using a CD.

Another object of the present invention is to provide a dialogue function to allow the user to play one sentence and alternately perform the user pronounce one sentence in order to enable the user to practice the conversation contents in the language learner using the CD. .

Another object of the present invention is to provide a language learner for reproducing language learning data stored in a CD, and having a variety of functions that can improve the efficiency of language learning, such as a repetition progress function and a dialogue function.

According to the present invention for achieving the above object, there is provided a method for repetitively reproducing voice data from a medium in which a predetermined series of unit voice data identified by different indices is stored. Receiving a value, starting the reproduction of the voice data, and reproducing the unit voice data one by one by the input repetition number value.

Further, there is provided a method for reproducing voice data in an interactive mode in the voice data reproducing apparatus, the method for reproducing a target including a unit voice data of a part of the series of unit voice data; Reproducing the series of unit voice data sequentially on the basis of the object to be reproduced, wherein the unit voice data belonging to the object to be reproduced is reproduced at a normal volume and so as not to be heard when reproducing the unit sound data not belonging to the object to be reproduced. Playing at a low volume.

1, there is shown a schematic block diagram of a language learner of the present invention. The language learner of the present invention includes an input unit 10, a microcomputer 20, a CD 30, a control unit 40, a display unit 50, a signal amplifier 60, and a speaker 70.

In one embodiment of the present invention, the input unit includes a plurality of function keys and numeric keys. The input unit may be configured as a touch screen in addition to a key. The key input information from the input unit 10 is input to the microcomputer 20 so that the microcomputer performs various tasks according to the state of the current language learner and the type of the input key. The microcomputer 20 operates to perform an algorithm as described in, for example, FIGS. 3 to 5 to provide CD control information and display information to the control unit 40 and the display unit 50, respectively. In accordance with the CD control information from the microcomputer 20, the control unit 40 controls the CD 30 to read the audio data stored in the CD and deliver it to the signal amplifier. As described above, the data area (2 in FIG. 2) of the CD 30 is divided into tracks and indices, and one unit audio data is recorded for each index. Preferably, the unit voice data is composed of one sentence. Therefore, the controller 40 reads the audio data recorded on the CD mainly in one sentence unit according to the CD control information from the microcomputer and outputs the corresponding audio signal to the amplifier 60. The voice signal input to the signal amplifier 60 is amplified according to the amplification ratio, and the amplified voice signal is output through the speaker 70. Preferably, the information about the amplification ratio is also provided from the microcomputer 20 to the control unit 40, so that the control unit 40 controls the signal amplifier 60 to adjust the volume of the audio signal output from the speaker 70. Adjust In response to the display information from the microcomputer 20, the display unit 50 displays contents that the user needs to recognize, such as a state of the current learner or contents that the user needs to input next. The display unit 50 may preferably include a liquid crystal screen.

The input unit 10 may include a PLAY KEY, a REPEAT ADVANCE KEY, a DIALOGUE KEY, a COPY KEY, and a numeric key. In addition, the present invention is not limited thereto and may include various keys according to the function of the language learner.

The playback function key is a key for starting playback of a series of unit voice data, i.e. sentences, stored on the CD. Pressing the play function key in the CD stop state enters the "play mode" in which a series of audio data or sentences stored on the CD is played. The playback function key can be operated in conjunction with various other keys as described below.

After the playback is started in response to the input of the playback function key, that is, when the follow function key is pressed in the playback mode, the mode is followed. In the follow-up mode, the voice data of the index (referred to as " current index ") being played at the moment the follow function key is pressed is played and then paused to follow the sentence for the current index. After that, whenever the follow function key is pressed, the current index is played and then it is in the idle state. Such a follow-up mode can be canceled by, for example, pressing and holding the follow-up function key.

The Repeat Progress function key is a key to play a sentence repeatedly as much as the repeat count value set by the user and proceed to the next sentence. When the repeat count value is input by using the numeric keys after pressing the Repeat Progress function key, "Repeat Progress Mode" ", The voice data for each index is repeatedly played as many times as the input number of repetitions, and the next index is played, and the sentences for all indexes can be heard as many times as the number of repetitions. This repeat function key is effective for listening practice. If the repeat progress function key is pressed when not in the play mode, the repeat of the sentence is started by pressing the play key to start the play after inputting the repeat count value, and when the repeat progress function key is pressed during the play mode, the play is performed when the repeat count is entered. Repeat playback starts immediately from the existing sentences. Such a repeat progress mode can be released, for example, by pressing the repeat progress function key again.

In addition, if a repeat progress function key is input after the follow function key is input, each sentence is repeatedly progressed with a pause corresponding to the length of the sentence at the end of each sentence. Repeat this several times, so you can practice.

The conversation function key is a function key for allowing the user to act as one of the speakers and the learner to act as the other when the sentences for the odd index and the sentence for the even index are different. Pressing the dialogue function key in the play mode enters the "conversation mode", where the odd index sentence is played and no sound is generated at the time corresponding to the play of the even index sentence (silent state). If you press the dialogue function key again in this state (conversation mode), only the even index sentences are played and no sound is generated at the time corresponding to the odd index sentences. Such a function can be implemented, for example, by making the amplification ratio of the signal amplifier of FIG. 2 very small during the reproduction time of the silent state. The conversation mode can be released by, for example, pressing and holding the conversation function key.

When the above conversation function key and the repeat progress function key are used together, the two indexes are paired, and the silent state for the odd (or even) index sentence reproduction and the even (or odd) index sentence reproduction time is repeated as many times as the repeat count value. It is also possible to implement a "conversational repeat progress mode" that proceeds to the next pair.

Hereinafter, a description will be given of the order in which the audio data is reproduced in each mode when the audio data corresponding to the indexes 1 to 6 are reproduced. The numbers indicate the index and [N] means the silent state where no sound is heard from the speaker for the time corresponding to the sentence of index N.

1) play mode

1-2-3-4-5-6

2) Repeat Progress Mode (Repeat Count Value = 3)

1-1-1-2-2-2-3-3-3-4-4-4-5-5-5-6-6-6

3) Repeat repeat mode (repeat count value = 2)

1- [1] -1- [1] -2- [2] -2- [2] -3- [3] -3- [3] -4- [4] -4- [4] -5- [5] -5- [5] -6- [6] -6- [6]

4) conversation mode

1- [2] -3- [4] -5- [6]

5) Conversation Repeat Progress Mode (Repeat Time = 2)

1- [2] -1- [2] -3- [4] -3- [4] -5- [6] -5- [6] or

[1] -2- [1] -2- [3] -4- [3] -4- [5] -6- [5] -6

Until now, only the reproduction of the audio data sequentially in the order of the indexes has been described, but it is also possible to perform the above operation only on the indexes included in the designated index set by specifying an index set of some of the indexes. In addition, it is also possible to designate the order to be played back when the index is specified so that the user can play back the order.

Referring to Fig. 3, an example of a logic flow diagram for reproducing voice in the above-described repeated progress mode is shown. 3 is a logic flow diagram for the case where the repeat progress function key is input in the stop state. When the repeat progress function key is input in the stop state (step 110), the repeat count value is to be input, and the repeat count value is input through the numeric keys in step 115. In step 120, the input of the play function key is awaited. When the play function key is input, for example, the current index is initialized to the first index (125). After resetting the current index, the remaining count value is initialized to the repeat count value (130), and playback of the current index is started (135). When the current index playback ends (140), the remaining number of times is reduced by one (145). If the remaining count value is not 0, the process returns to step 135 and playback of the current index is repeated. If the remaining count value is 0, the desired index number is repeated for the current index. After updating 155 to the index to be reproduced (for example, the current index + 1), the process returns to the initialization step 130 of the remaining number of times.

Referring to FIG. 4, another example of a logic flow diagram for reproducing voice in the above-described repeating progress mode is shown. 4 is a flowchart illustrating a case where a repetition progress function key is input in a reproducing mode. The repetition progress mode reproduction according to FIG. 4 performs the same operation as in the repetition progress mode reproduction of FIG. 3 except that the index for starting the repetition becomes the index being reproduced when the repetition number value is input, not the initial index.

In the regeneration mode, that is, if the repetition progress function key is input during regeneration of the index (step 210), the repetition number value is to be input, and the repetition number value is input through the numeric key in step 215. Thereafter, awaiting the end of the reproduction of the index ("current index") being reproduced at the moment when the repetition number value is input (220), and proceeds to the step 230 after the end to initialize the remaining number value. Steps 230 to 255 are the same as those of steps 130 to 155 of FIG. 3, and are for reproducing each index by the number of repetitions starting from the current index.

Referring to Fig. 5, an example of a logic flow diagram for reproducing voice data in the aforementioned conversation mode is shown. 5 is a logic flow diagram for the case where a dialogue function key is input in the playback mode or the dialogue mode. First, when the conversation function key is input 310, it is determined whether the conversation mode is the conversation mode or not (ie, the playback mode) (320). When the conversation function key is pressed in the reproduction mode, the conversation mode is changed to the conversation mode, and the object to be reproduced in the conversation mode is set to an odd index, for example (330). If the conversation function key is pressed again in the conversation mode, the existing playback object is changed (340). That is, the odd index is changed to an even index, and the even index is changed to an odd index. After setting the playback target, it waits for the end of playback of the current index currently being played (350), and after completion, updates the current index to the next index (for example, the current index + 1) (360). In operation 370, it is determined whether the content belongs to the reproduction target. If the updated current index belongs to the playback object, playback of the current index is started (390). If the updated current index does not belong, silent playback is started for the playback time of the current index (380). In one embodiment of the present invention, silent reproduction is performed by adjusting the amplification ratio of the amplifier shown in FIG. 1 so that the reproduced speech is not heard. When playback or silent playback for the current index ends (350), the same operation is performed again (360-390). As described above, since normal play or silent play are alternately performed depending on whether the object belongs to the play target, the user can pronounce the sentence of the silent play part and practice the conversation interactively with the language learner.

As described above, the CD has a better sound quality than the tape, and the sound quality does not deteriorate even after a long time of use.

According to the repetition progress mode of the present invention, one sentence can be repeatedly heard as desired by a simple key operation, and the repeat repetition mode can be repeated repeatedly, thus maximizing the efficiency of language learning. In addition, according to the conversation mode of the present invention, it is possible to practice in a conversation form, which is a form in which foreign language conversation is most frequently performed, so that the same effect as learning with a foreign teacher can be produced. The learner of the present invention can induce students' interest by using not only personal language textbooks but also as teaching aids of foreign language time in schools and institutes, and in particular, the correct pronunciation can be practiced even in classes taught by Korean teachers.

Although the present invention has been described with reference to exemplary embodiments, these descriptions should not be interpreted in a limiting sense. It will be apparent to those skilled in the art that the present invention may be variously modified, combined, or otherwise carried out with reference to the detailed description of the invention. Accordingly, it is to be understood that the following claims are intended to cover all such modifications and embodiments.
