And a time information area 304 for displaying time information necessary for a time, a voice data storage area 306 for storing voice data and text data for the learning content, and a text data storage area 308.

According to the present invention configured as described above, the language learning content in units of sentences is first converted into a digital signal and stored in the external memory card 210. In this case, the language learning contents including the text and voice data necessary for the language learning and the control information on the text and the voice data are generated in sentence units, and the contents are converted into digital signals and stored.

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.

Then, the external memory card 210 storing the learning contents is inserted and installed in the memory insertion unit 130 of the language learning apparatus, and then the learner uses the mode key 122 of the operation signal input unit 212 for language learning. When the operation is performed, a signal operated from the mode key 122 of the operation signal input unit 212 is input to the microprocessor unit 202, and the microprocessor unit 202 transmits the input operation signal to a preset program. It is controlled to switch to the language mode.

In the case of a search signal for learning contents by the mode key 110 of the manipulation signal input unit 212, the microprocessor unit 202 stores any data stored in a digital form by a write address inside the external memory card 210. After directly accessing the learning content of the search and reading the learning content information recorded in the header portion is displayed through the LCD 108 to the learner through the LCD control unit 214.

In this case, the display may display the digital signal processor 204, the encoder / decoder 206, and the output amplifier 218 as a voice signal through a speaker.

The learner may change the operation mode using the fixed key 120 of the operation signal input unit 212 or fix the selected operation mode based on the displayed learning content information.

When the learner presses the play key 124 of the operation signal input unit 212 after selecting and fixing the learning mode, the microprocessor unit 202 outputs a control signal corresponding to the learning content previously selected by the learner. The learning content stored in the external memory card 210 by being output to the memory card 210 is output to the digital signal processor 204, and the digital signal processor 204 processes the learning content to encode / decode the unit 206. After converting into an analog signal through the amplified by the output amplifier 218 is output through the speaker 116 as a voice.

On the other hand, when the learner presses the play key 124 of the operation signal input unit 212 in the fixed state by selecting the learning mode, the microprocessor unit 202 corresponds to the learning content previously selected by the learner. Outputs a control signal to the external memory card 210 to select a sentence to be reproduced among the selected contents of the learning contents stored in the external memory card 210, and then outputs character data for the selected sentences to the microprocessor unit 202. The microprocessor unit 202 outputs text through the LCD 108 through the LCD control unit 214.

At this time, the series of processes are repeated until the operation mode of the language learning apparatus is changed by the learner's selection.

In addition, when the learner presses the speed controller 104 of the operation signal input unit 212, the microprocessor unit 202 determines that the selected operation mode is a playback speed control mode and is stored in the external memory card 210. After changing the pulse width of the digital signal by a certain ratio and setting the reproduction speed to the speed selected by the learner, the digital signal processor 204 processes the learning content and converts the analog signal to the analog signal through the encoding / decoding unit 206. Amplified by the output amplifier 218 and output through the speaker 116, or outputs the voice and text data for the selected sentence to the microprocessor unit 202, the microprocessor unit 202 in the LCD control unit 214 ) Outputs to the LCD 108 at the playback speed selected by the learner.

Meanwhile, when the learner presses the repetition key 112 of the manipulation signal input unit 212, the microprocessor unit 202 determines that the selected operation mode is the repetition section setting mode and controls the LCD control unit 214 to control the LCD. A repeating section is displayed in units of time or sentence through 108. In this case, the setting of the repeating section sets a time for reproducing an arbitrary sentence repeatedly by pressing the learner's repeat key 112 in the case of time. If the setting criterion is not time, the repeat start section and the end section in sentence units are set by the learner's external manipulation.

When the learner presses the training key 114 of the manipulation signal input unit 212, the microprocessor unit 202 changes the selected operation mode to the practice mode to display the practice mode through the LCD 108. .

Therefore, the learner inputs the corresponding sentence in accordance with the learner's corresponding learning contents through a microphone, and the inputted input is a digital signal through the input amplifier 216 and the encoder / decoder 206. The encoded learning information is encoded and stored in the digital signal processor 204, and the stored learning contents are reproduced by pressing the play key 14 again to reproduce the recorded learner's voice.

As described above, the present invention stores the voice data, the text data, and the control data of the corresponding learning content when storing the learning contents in a sentence unit on an external memory card, thereby processing the voice data and the text data together during the playback. The learning content can be easily controlled to facilitate the use and improve the language learning effect.
