In addition, the logic switch unit 20 is configured such that an external input signal from the line input terminal 24 is input, and a microphone signal amplifying unit (2) in which an audio signal input through the microphone 25 is controlled by the microcomputer 10 ( In step 26), the equalization amplification is performed so that another voice input is performed.

The reproduced audio output of the recording / playback signal processing section 29 having the recording / playback head 27, the erasing head 28, and the recording and erasing oscillation section 30 is also applied to the logic switch section 20 as a voice input. In addition, the audio reproducing output of the voice digital signal processing unit 21 is also configured to be applied to the logic switch unit 21 as one voice input signal.

The oscillator 30 may be provided with a selection switch circuit for noise cutting and AM bit cutting.

The logic switch 20 is a microphone input signal and recording / playback signal processing unit 29 through the radio broadcast signal and the microphone signal amplifier 26 of the AM / FM receiver 19 input under the control of the microcomputer 10. Is selected to apply to the voice digital signal processor 21 by selecting one of the tape reproducing signal and the external voice input signal inputted through the line input terminal 24.

The voice digital signal processor 21 converts the analog signal input through the logic switch unit 20 into a digital signal, records and stores the analog signal, and then stores the voice digital data once or repeatedly according to the control signal of the microcomputer. To convert the data into a playback output.

The AMSS section 31 is connected to an AMSS interval setting section 16 for determining sentence detection conditions (set values of no signal sections). The AMSS interval setting section 16 selects an interval length at the time of sentence detection. An interval selection switch 15 is provided.

An operation of the learner configured as described above and a control method thereof will be described in detail with reference to the flowcharts of FIGS. 2 to 9.

First, when the operating power is supplied to the learner system, the microcomputer 10 reads a signal from a sensor (not shown), which is a tape provided in the deck unit 18, and indicates whether the tape is mounted on the display unit 11 or not. Display as a picture.

The tape-mounted display means has a tape reel shape as a continuous dotted line, and the tape display element of the dotted line shape is sequentially lit according to the running direction of the tape to indicate the running direction.

In the tape-mounted state, recording and playback are possible in accordance with the function selection of the key input unit 12 in the mode selected by the language / normal playback (L.L / REV) selection switch 14.

Hereinafter, only the case where the language / general reproduction selection switch 14 is selected as the language position will be described.

2 shows a schematic overall operational flow diagram of the present invention.

As referred to herein, the learner user selects a desired function by operating the language / general regeneration selection switch 14 in the first step while the power voltage is applied to the language learner. The microcomputer 10 performs a subroutine for executing normal playback and recording of the tape. In contrast, if the language learning function selection mode is performed, the microcomputer 10 determines whether the sentence repetition function is selected.

If the sentence repetition function is selected in the second step, the sentence repetition subroutine is performed following the setting of the sentence repetition condition. If there is no selection of the sentence repetition function, the third step is executed to determine whether the section repetition function is selected. Judge.

In the above step, if the interval repetition is selected, the interval repetition subroutine is performed following the setting of the interval repetition condition. If there is no selection of the interval repetition function, the fourth step is executed to determine whether the infinite repetition function is selected.

If the infinite repeat function is selected in the fourth step, the infinite repeat subroutine is performed following the setting of the infinite repeat interval. Otherwise, the process proceeds to the fifth step to determine whether the test function is selected.

If the test function is selected in the fifth step, the test function subroutine is performed. If there is no test function selected, the test function goes to the sixth step and determines whether the interactive function is selected.

If the conversation function (I, II) is selected in the sixth step, the conversation function subroutine is performed according to the conditions corresponding to the conversation I or the conversation II.

On the other hand, if there is no selection of the conversation mode in the sixth step of determining whether the conversation function is selected, the seventh step of determining whether the digital memo function is selected is executed.

If the digital memo function of the message is selected in the seventh step, the digital memo / playback function subroutine is performed. However, if there is no selection of the digital memo function, it enters the standby state, and this standby state is canceled according to the function selection key input from the key input unit 12, and the selection and selection of the function selection is performed again from the first step. The function will be executed.

3 is a detailed flowchart of a sentence repetition process in the present invention.

First, the sentence repeat function by the key input unit 12 is switched in a toggle form in which the sentence repeat function is selected by the first key input and the function is released by the next key input.

Therefore, while the sentence repeat function is selected, the play key is input, and the sentence repeat function is canceled and the normal playback mode is entered.When the stop key is input, the microcomputer determines that the system is stopped and the deck portion is released with the sentence repeat function released. Control 18 in the stop mode.

On the other hand, if the sentence repetition function selection is followed by the selection key input for the number of sentences, the setting registration of the number of sentences S or the registration of the change of the previous value are executed. Run

The set value of the number of sentences and the set number of repetitions are displayed by the two-digit digit on the SENTENCE cover of the display unit 11 and the two-digit digit display means on the REPEAT cover.

If there is a play key input following the above condition setting, the microcomputer 10 controls the deck unit 18 so that the contents recorded on the learning tape are picked up through the recording / playback head 27 to record / playback signal processor 29. Amplify and Equalize in order to output.

At this time, the audio mono output of the recording / playback signal processor 29 is input to the AMSS unit 31, and the sentence is detected and input to the microcomputer 10 according to the recognition of the non-signal period. The number can be detected.

Here, when the microcomputer detects the sentence according to the set condition, the microcomputer counts and displays the value on four numeric display digits provided at the lower right of the display unit 11.

When the count value corresponding to the set number of sentences is obtained, the microcomputer repeatedly controls the deck unit 18 based on the count value so that the desired sentence can be continuously played repeatedly as many times as desired to improve the learning effect. Will be.

After completion of the set number of times the sentence repeat through the set count for the number of times, the microcomputer releases the sentence repeat function and switches the deck to the normal playback mode.

4 is a detailed flowchart of the interval repeating function according to the present invention.

As referred to here, the microcomputer controls the system in the normal play mode with the release of the interval repeat function if there is an input of the play key while the interval repeat function is selected, and there is an input of the stop key. Judgment is made, and the deck unit 18 is controlled in the stop mode with the release of the sentence repeat function.

On the other hand, if there is a starting point setting of the repeating section following the selection of the section repeating function, the microcomputer starts counting and ends the count when the end point of the repeating section is input, retains the corresponding count size, and then rewinds the tape.

When the tape is rewound, the count point is found by down counting the count value, and from this point, a repeating play of a predetermined number of times is performed based on the count value.

After the repeated playback is completed in a predetermined number of sections, the microcomputer releases the section repeat function and switches the system to the normal playback mode.

In particular, in the interval repeat mode, A-B REPEAT is displayed on the display unit 11 and the number of repetitions is also displayed.

5 is a detailed flowchart of the infinite repeat function operation according to the present invention.

Here too, if the input of the play key is selected while the infinite repeat function is selected, the microcomputer controls the system in the normal play mode with the release of the infinite repeat function. The deck unit 18 is controlled in the stop mode with the release of the repeat function.

On the other hand, when the infinite repeat function is selected, the microcomputer 10 controls the logic switch unit 20 so that the analog audio output of the recording / playback signal processor 29 is input to the voice digital signal processor 21 via the logic switch unit. .

At this time, the voice digital signal processing unit 21 converts the analog voice signal into a digital value and records the data in the memory chip. Such digital recording time information is recorded in several recording / playback times on the display unit 11 connected to the microcomputer. The indicator bar will indicate the physical quantity.

The indicator bar in the display portion 11 of FIG. 1, which shows an embodiment, is composed of four pieces and indicates a predetermined time value (4 seconds) per one, so that the user can accurately grasp the operation state of the current digital recording mode.

The digital recording of the voice signal is continued until the maximum recording condition is reached within the memory supported range unless the stop key is input by the key input unit 12, and when the memory pool condition is reached, the microcomputer 10 does this. Automatic recognition and recording stop automatically.

When the recording stop command is input to the microcomputer through the key input unit 12, the microcomputer switches the deck unit 18 to the pause mode, and then controls the voice digital signal processor 21 and the main amplifier 33 to control the voice. The voice digital signal contained in the memory of the digital signal processor 21 is converted into an analog voice signal and output through the logic switch unit 20.

The voice signal output of the logic switch unit is amplified by the main amplifier 33 having the volume controller 32 and output through the speaker 34.

Herein, the analog audio signal which is digital-analog converted by the voice digital signal processor 21 and output from the logic switch unit 20 appears at the line output terminal 23 via the line amplifier 22.

Recording and infinitely repeating playback of the digital audio signal are performed by outputting the stop, playback, and recording control signals from the microcomputer 10 to the audio digital signal processor 21. The endless repetition function by the digital memory is stopped and the tape deck 18 and the recording / playback signal processor 29 are controlled to switch to the normal playback mode.

During the infinite repeat function, several recording / playback indicator bars light up one by one on the display unit 11 in order to measure the length of the remaining recording and playback time, and IC REPEAT is displayed to inform the operation state of the function.

6 is a detailed flowchart of a test function according to the present invention.

At this time, if the input of the play key is selected during the test function selection, the microcomputer controls the system in the normal playback mode with the release of the test function.If the stop key is input, the microcomputer determines that the system is stopped and the test function is released. The deck unit 18 is controlled in the stop mode.

In the test mode, the sentence is detected and rewound according to the sentence detection method described above, and then the learner's voice signal is digitally recorded on the voice digital signal processor 21 when the learner follows the tape (sentence) playback by the microcomputer. This feature allows the self-pronunciation to be tested against the tape playback output.

That is, after one sentence is detected and rewinded, the microcomputer 10 drives the deck unit 18 and the recording / playback signal processor 29 to reproduce the detected sentence and simultaneously amplifies the microphone signal. By controlling the unit 26, the logic switch unit 20, and the voice digital signal processor 21 to follow a learner's pronunciation input through the microphone 25, the voice is passed through the logic switch unit 20 to the voice digital signal processor ( Control to record the voice.

Then, after the detection sentence of the tape is reproduced, the microcomputer pauses the tape playback and this time, it is possible to improve the learning effect by outputting and comparing each other's pronunciation pronunciation recording signals recorded by the learner recorded in the voice digital signal processor 21. It would be.

When this process reaches the set number of times (for example, three times), the microcomputer stops the test function and switches the learner to the normal tape play mode.

In particular, when listening to a sentence reproduced on the tape and playing the voice again, the IC REPEAT on the display unit 11 is turned on to accurately represent the current function.

Particularly, in the test mode, the speaker indicator on the display unit 11 blinks during tape playback to indicate the present tape mode, and the human indicator flashes during the playback of the digital voice stored in the memory. .

In addition, when the learner pronunciation playback mode, several recording / playback indicator bars are sequentially turned on as the digital playback time elapses, thereby making it possible to estimate the remaining time of the digital audio playback mode.

7 is a detailed flowchart of the first conversation function according to the present invention.

At this time, if the input of the playback key is input during the selection of the first conversation function, the microcomputer releases the first conversation function and controls the system in the normal playback mode. The deck unit 18 is controlled to the stop mode with the release of the function.

The start of the conversation function starts by detecting one specific sentence through replay and then counting the length of the sentence.

After that, the microcomputer pauses the tape driving for that time by adding a predetermined time (about 1-2 seconds) to the length of the sentence, thereby providing the learner with the pronunciation practice time during the blank time.

After that, after a predetermined time (length of detected sentences plus 1-2 seconds), the tape pause state is released under the control of the microcomputer, and the second sentence is detected. Second) will give learners the time to follow the second pronunciation.

This conversation function is released by the break key input of the first conversation function and the learner system performs a normal playback mode.

In this conversation mode, the speaker indicator on the display unit 11 blinks during playback of sentences on the tape, indicating that the current tape is in play mode, and the human indicator blinks during the learner's follow-up period. Doing so indicates that it is the time given to the learner.

8 is a detailed flowchart of a second conversation function according to the present invention, most of which is the same as the first conversation function described above. The difference is that if one sentence is detected during playback of the learning tape, the system control micom pauses the tape. In the stop mode, the microphone signal amplifier 26 and the logic switch 20 are controlled to determine whether or not a voice signal is input through the microphone 25.

In this way, when the learner's voice is inputted through the microphone, when the following voice input is completed, the microcomputer releases the pause of the tape and executes playback to detect the second sentence.

Here, as in the dialogue function of the first stage, the second dialogue function is canceled by the break key input of the second dialogue function, and the learner system performs the normal playback mode, while the speaker on the display unit 11 is in progress. The current mode and status are displayed by the sequential blinking of the indicator and the human indicator.

Next, the digital voice memo function of the present invention will be described in detail with reference to the circuit block diagram of FIG. 1 and the flowchart of FIG.

First, when there is a digital memo key input in the standby state of the system, the microcomputer 10 controls the microphone signal amplifier 26, the logic switch 20, and the voice digital signal processor 21 together with system power-on control. The analog voice signal input through the microphone 25 is input to the voice digital signal processor 21 through the logic switch 20 to be converted into a digital value and stored in the internal memory.

At this time, the recording time is displayed by the sequential lights of several indicator bars provided on the display unit 11, and the message recording is automatically stopped when the memory full state indicated by the lighting of all the indicator bars is displayed.

Such digital conversion voice recording can be deleted by using a reset key. After the memo of the voice message is completed, the data recorded in the memory of the voice / digital signal processor 21 is input according to the input of the digital voice recording playback key of the next person or a third party. Is converted into an analog voice signal and output through a speaker.

At this time, the remaining amount of the audio digital reproduction time can be confirmed through the sequential lighting of the indicator bar of the display unit 11.

On the other hand, the microcomputer 10 has a microphone on / off switch 13 for turning on / off the microphone signal amplifier 26 for signal amplification input from the microphone 25, a language learning function and a general cassette tape in tape playback. A language / general reproduction selection switch 14 for selecting a function is connected.

As described above, the present invention provides a method of repeatedly recording and reproducing a voice signal for an important sentence in a digital memory device when repetitive listening and pronunciation practice learning is performed using an audio learning tape, thereby reproducing it. It is possible to solve the problem of other faults and discontinuities in the continuous operation of, which can significantly enhance the learning effect.

In addition, since the present invention has a digital memo function for message delivery and important matters according to the digital signal processing method of the voice signal, it is convenient to play a role as a home voice memo notebook in addition to the learner.

In addition, the present invention has a function that can arbitrarily adjust the interval of the detection no-signal period during the operation of the AMSS, so that the sentence detection can be effectively made even for the recorded learning tape in which the no-signal period for each sentence is set differently from the standard value.
