It is about.

Through a microcomputer amplifier that can control the compact disc analyzed by CD deck analysis, which reads CD and analyzes and classifies data by the signal input to the keyboard control panel which can be operated arbitrarily and externally amplifies the microphone amplifier. A data output controller that controls the output of incoming audio signals to display devices, video, and audio, and comparators that compare the external sound with the original sound. By comparing and analyzing their pronunciation, you can practice foreign language learning step by step, set your own repetition points, and listen to them repeatedly. You can also specify the number of repetitions to hear as many times as you want to hear.

The present invention relates to an automatic repetition and interactive automatic adjustment device of a compact disc, and in particular, it is possible to repeatedly watch an audio signal, and to perform foreign language learning in a short time by comparing and analyzing the reproduced sentences and their pronunciations. It is about.

In a conventional compact disc player, a control device reads a predetermined time and a music selection section by a switch operatively inputted to an operation panel.

In the conventional configuration, since the automatic repetition can be performed by selecting a piece or an interval by using data of a track recorded at a constant time or time, it is inconvenient to actually set a desired repeat point, and the number of repetitions is not set. I had to operate it several times.

SUMMARY OF THE INVENTION An object of the present invention for solving the conventional problems is a device capable of moving to a playback method during playback or pause, a function device for selecting and selecting a sentence selection or a selection number of repetition times, and a function of adjusting the interval between sentences and selections. By constructing the device and the waveform comparison function device of the reproduced original sound and the practice sound, the user's pronunciation and the original sound are compared and analyzed to facilitate foreign language learning.

Hereinafter, the technical configuration of the present invention to be attached in detail as follows.

Micom CD controller which controls compact disc analyzed by CD deck analyzer which reads CD and analyzes and classifies data by input signal to keyboard control panel which can be operated arbitrarily and microphone amplifier which can amplify external voice It is composed of a comparator that is output to the display device, video, and audio and compares the external sound with the original sound by a data output controller that controls the output of the voice signal coming in through the amp.

Referring to the effect of the configuration of the present invention in detail as follows.

As shown in the system configuration of FIG. 1, the CD control micom drives the CD deck, analyzes the data read from the CD, and transfers the input function to the data output control unit. The data output control unit analyzes and sorts the received data and sends it to the display device, audio and video output unit, and compares the original sound and the practice sound of the audio according to the function selection of the keyboard, and sends the signal sound waveform to the microcomputer and immediately from the microcomputer. The display device and CD deck are driven and controlled so that the output can be confirmed and compared with the waveform state of the external microphone.

As shown in FIG. 2, which shows the circuit configuration in a flow chart, the CD control microcomputer by the operation input of the keyboard operation panel changes the data of the CD read by the laser sensor in driving the CD deck. The data is analyzed and processed, and the processed data is sent to the time clock generation control unit, mixed with the clock data, distributed to the data determination unit, and received by the system clock signal and output to the data distribution unit.

The data distribution unit divides various data by signals and distributes and outputs CD track data, audio, video, and time clock data to respective functional units, and each functional data management unit selects and outputs only necessary data.

In addition, when the final data is sent to the control signal processing unit, the control signal processing unit inputs from the control panel to check the execution result of the function, and sends it to each function unit like a time clock to be controlled and output.

As shown in FIG. 3 showing the keyboard input device, the reversal 10 of the adjusting device for the automatic repeat of the compact disc is moved in the opposite direction, that is, in the forward direction, in which one track is played during the CD play or pause function. It is an input button of the function, the start button 20 is a function device capable of playing the selected sentence or the sound to be listened to, and the backward movement 30 is to move forward the playback progress direction by one track during playback or pause. It is a device with the ability to

In addition, the power button 40 is a device for power supply to turn off and on the system power supply, the stop button 50 is a device of the function to stop the system function, the pause button 60 during playback It is a device having a function of reproducing the pause buffer by reactivating the pause buffer without reproducing through the start button 20.

On the other hand, the button number 70 to 160 button indicating the number is a device to be selected by specifying the number of sentences selected or the number of repetition of the selected portion, the cancel button 170 is a number button (70 ~ 160) Is a device equipped with a function to remove the number of sentence selection or repetition designation, the interval control 180 is a device of the function that can adjust how much to choose a sentence or selection and the interval, sentence selection 190 is It is a device for selecting a sentence to be listened to during playback or pause.

In addition, the repetition frequency selection 200 is a device of a function of automatically selecting a predetermined number of times by selecting a sentence or a selected portion of the user, the repeat button 210 is a stop signal irrespective of the specified repetition number of sentences or selections Is a device of the function of repeating repeatedly until the input function, the comparison function 220 is a device of the function of listening to the difference between the reproduced original sound and the practice pronunciation, the listen 230 to listen to the sentence that you just heard continuously When the device is a function of operating when, the practice function 240 is a device having a 1: 1 interactive pronunciation practice when trying to practice the original sound.

Through this operation, the user can repeatedly listen to the audio signal, and can practice foreign language learning step by step by comparing and analyzing the sentence being reproduced with his / her own pronunciation, and by repeatedly setting the desired repeat point.

In addition, it is a novel useful invention that has the effect of being able to specify the number of repetitions and can be heard repeatedly as many times as desired.
