Referring to FIG. 4, in order to control a language learning apparatus according to the present invention, first, a language learning content of a sentence unit is converted into a digital signal and stored in an external memory card (s401). In this case, it is necessary for the language learning. Language learning contents including text and voice data and control information on the text and voice data are generated in sentence units, and the contents are converted into digital signals and stored in an external memory card.

The generated language learning content has a format as shown in FIG. 3, and the control information included in the language learning content includes identifier information for identifying a chapter or a section including the learning content, and the learning content. It tells the time information required when it is played.

After installing the external memory card storing the learning contents in the language learning apparatus, when the learner requests a search for the learning contents from the outside for language learning, the random memory stored in the digital form by the record address inside the external memory card is stored. The learner directly accesses the learning content of the user and displays the learning content information recorded in the header part to the learner (s402). In this case, the display method may be performed by using a voice signal through a speaker or an image signal through the LCD device. have.

When the learner selects the desired learning content and the operation mode by viewing the displayed learning content information (s403 and s404), the operation mode of the language learning apparatus is changed to the selected mode and then the operation corresponding to the selected operation mode is performed.

When the learner selects the play mode in the process s404, the learner converts the learning content previously selected by the learner (s403) into voice and text data and outputs it to the learner. After the selection (s406), the voice and text data for the selected sentence are output (s407). If there is a preset content for the learning environment such as a playback speed, waiting time, and repetition period, the voice and Output character data. At this time, the series of processes s406 and s407 are repeated until the operation mode of the language learning apparatus is changed by the learner's selection.

In addition, when the operation mode selected in the step s404 is a playback speed adjustment mode, the pulse width of the digital signal stored in the external memory card is changed by a predetermined ratio, and the playback speed is set to the speed selected by the learner (s409). When the operation mode selected in the process s404 is a standby time setting mode, a waiting time is set before playing any learning content by external operation of the learner (s410). The waiting time can be set.

On the other hand, if the operation mode selected in the step (s404) is a repeating section setting mode to set the repeating section in time or sentence units by the learner's external operation, first, by checking the repeating section setting criteria (s411), the repeating When the section setting criterion is time, a time for reproducing an arbitrary sentence is repeatedly set by a learner's external manipulation (s412). When the section setting criterion is not time, a repeating start section in sentence units by the learner's external manipulation and The end section is set (s413).

Therefore, when the apparatus for learning language is applied to the present invention, the learning contents are output according to the environment with reference to the set reproduction speed, waiting time, and repetition period.

Finally, if the selected operation mode in the process (s404) is the pronunciation practice mode to change the operation mode of the language learning device to the recording mode to record the learner's voice, the process of repeating the contents to the learner To explain a series of processes with reference to the drawings as follows.

First, a sentence to be reproduced is selected for the pronunciation practice (s414), and voice and text information on the selected sentence is output (s415), and then the operation mode of the language learning apparatus is converted into a recording mode (s416). . When the learner follows the corresponding learning content, the learner's pronunciation of the sentence is recorded (S417), and the recorded learner's voice is reproduced (S418).

At this time, the conditions for outputting the selected sentence are the same as in the case of the normal playback mode. Then, the processes s414 to s418 are repeatedly performed until the learner selects another operation mode.

As described above, the present invention stores voice data, text data, and control data of the corresponding learning content when storing the learning content in a sentence unit on an external memory card, thereby simultaneously processing the voice data and the text data during playback and corresponding learning content. There is an advantage that can easily control the. In addition, this allows for more effective language learning.
