Abstract

PURPOSE:To enable effective learning by repeating the operation for rewinding a teaching material tape up to the head of a document right before a blank period and then switching the mode to a rerecording mode again when the end of the blanking period of a 1st track or its continuance which is longer than a constant period is detected in the rereproducing mode. CONSTITUTION:If the blank period of the 1st track end or continues abnormally for the constant period in the rerecording mode, the teaching material tape is rewound up to the head of the document right before the blank period and the rereproducing mode is entered. At this time, if the blank period of the 1st track ends or continues for the constant time, the teaching material tape is rewound up to the head of the document right before the blank period and the rerecording mode is entered repeatedly. Consequently, the most effective learning as repetitive learning in 'pronunciation learning' becomes possible and a great result can be expected in the learning effect of the speech practice in the language learning.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a tape recording and playback system for language learning used in a group learning device consisting of a console device for a teacher and a plurality of booth devices for students connected to the console device. Regarding equipment.

(Conventional technology) Language such as English and French
Laboratory, LearningLabo
ratory > In group learning devices used in classes, one center system (console unit) on the teacher side performs two-way communication with multiple terminals (booth units) on the student side connected to it. , is in overall control.

In the above group learning device, the teaching material tape (master tape) is played back by the master tape recorder (MTR) of one console device on the teacher's side, and recorded by the booth tape recorder (BTR) of the booth device of each student. , so-called "r student dubbing" is performed.

After that, each student performs ``self-study'' by (1) listening to the teaching materials by operating their own BTR, and (2) recording their own voice (pronunciation) while listening to the teaching materials.

The student teaching material tape (student-dubbed tape) used for learning by listening to teaching materials (listening learning) of the above self-study method has multiple sentences separated by blanks (blank areas). recorded continuously.

When performing the above-mentioned ``listening technique'', learn by listening to each sentence in the teaching material repeatedly. As shown in Figure 5, the sentence period and blank period of the teaching material tape are detected by the audio detector of the BTR, and the tape position (tape counter value) corresponding to the timing of generation of the detection pulse is stored in advance. For example, by pressing the repeat button while playing a sentence (before reaching the next blank),
The BTR can repeat the process of rewinding the tape to the beginning of the sentence (■) and then playing the same sentence (■) again.

In addition, among the above 1. Self-study, ■Your own voice (pronunciation)
A teaching material tape for students used for recording and learning (pronunciation learning) is first obtained by "student dubbing" using a master tape that is master-dubbed from a commercially available teaching tape using a console device.

In master dubbing, a commercially available teaching tape as shown in Figure 6(a) is played back on one of two master tape recorders (VTRs) installed in the console device, and the other one is played back.
This is done by recording on a separate tape on a stand.

During master dubbing, when a blank between sentences in the teaching material on the playback side is detected during dubbing, the tape running of the MTR on the playback side is temporarily stopped, as shown in Fig. 6 (b).
As shown in Figure 2, a blank period of approximately the same length (time) is automatically created next to one sentence on the master tape that has been master dubbed. Therefore, by dubbing this master tape for students, a teaching material tape for students recorded with a similar blank period can be obtained.

In the above ■ "Pronunciation learning (self-study)", while playing the teaching material track (first track) of the student's teaching material tape, the generated sound track (second track) is played in the next blank period of the sentence. This is done by recording your voice (pronunciation) on a track).

(Problem to be Solved by the Invention) By the way, in language learning, it can be expected that great learning effects can be obtained by practicing the same sentences over and over again. In the case of "pronunciation learning" mentioned above, a learning method is also used in which the same sentences are repeated over and over again.

FIGS. 7(a) and 7(b) are diagrams showing an example thereof.

In "pronunciation learning," the sentences on the teaching material track (first track; hereinafter referred to as ) of the teaching material tape shown in the figure are played back, and the generated sounds are recorded on the generated sound track (second track; hereinafter referred to as ■). .

That is, a text with a teaching material track (■) (for example, a text
), then play and listen to the generated sound track (
Record your own voice (generated sound) during the period corresponding to the next blank period of the same sentence (sentence ■) in (■).

At this time, by pressing the repeat button before reaching the beginning of the next sentence (sentence ■), the end point of the next blank period of the sentence (sentence ■) that was played back and listened to (i.e., the next sentence ■ When the tape reaches the sentence rIA), the tape is rewound to the beginning of the sentence (sentence ■) that was played back and listened to.

After the tape is rewound, the teaching material track (■〉
Play the sentence, record the generated sound on the generated sound track (■〉), and tape it at the end of the next blank period (i.e., the beginning of the next sentence H) of the sentence that was also played back and listened to. When the time limit is reached, the tape is rewound to the beginning of the sentence (sentence ■) that was played back and listened to. Repeated learning ("pronunciation learning") is performed by repeating the process several times (for example, about 10 times).

In another conventional example, the text on the teaching material track (■) is played back, the generated sound is recorded on the generated sound track (■), and after the tape is rewound, the text on the teaching material track (■) is played back. Play, and also play the generated sound on the generated sound track (■),
After the tape is rewound in the same way, the sentences on the teaching material track (■) are played again, and then the sentences on the sound generation track (■) are played again.
The generated sound is also played. Play the above teaching material tracks (■).

After recording the generated sound track (■) and rewinding only once, "playing both tracks (■, ■) and rewinding" is repeated several times (for example, about 10 times). Iterative learning is performed by

Here, when learning repeatedly in "pronunciation learning", as shown in Figure 3, first, play and listen to the sentences in the [A] teaching material, then use it as a model, [B]
After recording your own voice (generated sound) and rewinding the tape, [C] Play and listen to the same sentence from the teaching material again, and then [D] Listen to your own recorded sound. There is a cycle of playing it back, listening to it, and comparing it with the model teaching material. By repeating this cycle of A-+B → C-+D, each cycle creates a new voice (generated voice). Re-record the sound), play it back, listen to it, compare it with the text in the model material (i.e., the pronunciation it was played back), and try to pronounce it anew and better on your own in the next cycle. Re-record the voice (sound generated),
The most effective repeated learning method is to repeatedly compare materials with model materials.

However, in the case of repeated learning in the conventional example above, ``pronunciation learning j'', in the former conventional example, the user plays back and listens to his or her own generated voice (generated sound) and compares it with the pronunciation obtained by playing back the sentences in the model teaching material. I couldn't.

In addition, in the latter conventional example, the voice produced by oneself (generated sound)
However, it is not possible to re-record the voice (generated sound) of a certain sentence and compare it with the model teaching material.

Therefore, all of the conventional examples described above have the disadvantage that the most effective learning method for repeated learning in r pronunciation learning j cannot be performed.

Therefore, the present invention solves the problems of the conventional technology described above,
It is an object of the present invention to provide a tape recording and reproducing device for language learning that enables the most effective learning method as repeated learning in "pronunciation learning".

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a first track in which - sentences and subsequent blank periods of approximately the same li1 or longer period are alternately and consecutively arranged. A device for language learning in which a recorded teaching tape is played back, and sounds generated during a period corresponding to the blank period of the first track on a second track formed substantially parallel to the first track are recorded and played back. The tape recording and reproducing device includes a detection means for respectively detecting a sentence period and a blank period of a first track of the teaching material tape, and a detecting means for reproducing the sentence recorded on the first track and generating sound on the second track. a switching means for switching between a re-recording mode for recording and a re-re-mode for reproducing the sentences and generated sounds respectively recorded on the first and second tracks; a rewinding means for rewinding the teaching material tape; and a rewinding means for rewinding the teaching tape; and an operation@switching means for controlling each operation of the switching means and the rewinding means by an output, and the operation control means is configured to control each operation of the switching means and the rewinding means by the output of the detection means when the switching means is switched to the re-recording mode. 1st
When the end of the blank period of a track or the continuation of the blank period of the first track for a certain period or more is detected, the rewinding means rewinds the teaching material tape to the beginning of the sentence immediately before the blank period, and then The switching means is switched to the re-re-mode, and when the switching means is switched to the re-re-mode, the end of the blank period of the first track or the continuation of the blank period of the first track for a predetermined period or more is also detected by the output of the detection means. When this happens, the teaching material tape is rewound by the rewinding means to the beginning of the sentence immediately before the blank period, and then the operation of switching the switching means to the re-recording mode is repeated! The present invention provides a tape recording and reproducing device for language learning, which is characterized by the following characteristics.

(Function) In the language learning tape recording/playback device configured as described above, during the re-recording mode, when the blank period of the first track ends or the blank period of the first track continues for a certain period of time, the tape recording/reproducing device immediately before the blank period ends. The teaching material tape is rewound to the beginning of the sentence, and then enters the replay mode. At this time, if the blank period of the first track ends or the blank period of the first track continues for a certain period of time, the tape will be rewound immediately before the blank period. The teaching material tape is rewound to the beginning of the sentence, and then the re-recording mode is repeated.

In the above configuration, first, the operation of master dubbing will be explained.

The signal from a commercially available teaching tape played back by the MTRI teaching head 3 is amplified by the playback amplifier 4, and the playback output is sent to the VTR.
The data is supplied to the teaching material head 10 through the recording amplifier 11 of No. 2 and the changeover switch 13 switched to the recording amplifier 11 side, and is recorded on another tape and master-dubbed.

During this master dubbing, the MT on the playback side during dubbing.
When the speech detector 5 of Rl detects a blank between sentences in the teaching material, the detection pulse is supplied to the M-CPU 6,
- The CPLI 6 controls the VTR drive 8 according to the timing of generation of the detection pulse to temporarily stop tape running. As a result, a master tape as shown in FIG. 6(b) is obtained in which a blank period of approximately the same length (time) is created next to one sentence.

Next, the operation of listening learning, in which each student operates his or her own BTR and repeatedly listens to sentences in the teaching material, will be explained.

BTRn teaching material tapes dubbed by students (i.e., tapes in which multiple sentences are recorded consecutively, with blanks separated by dubbing commercially available teaching tapes).
The signal reproduced by the teaching material head 21 is amplified by the reproduction amplifier 24 switched to the reproduction amplifier 24 side, and the reproduction output is supplied to the audio detector 39. When the audio detector 39 detects a blank between sentences in the teaching material, the detection pulse is supplied to the B-CPU 30, and the B-CPU 30 adjusts the tape position according to the generation timing of the detection pulse using a tape counter (m). is stored in the memory 32.

By pressing the repeat button (not shown) while playing a sentence (before reaching the next blank), each student can
- The CPU 30 controls the BTR drive 34 to rewind the tape to the beginning of the sentence, and then reproduces the same sentence again, which is repeated.

Next, BT in FIG. 1, which is an embodiment of the device of the present invention,
Repeated learning in "pronunciation learning" by Rn will be explained.

In the configuration of BTRn shown in Figure 2, the recording button (3
When 1> is pressed, the practice recording state (re-recording mode) is entered, and switching control signals are supplied from the B-CPU 30 to the changeover switches 22 and 26, respectively, and the changeover switch 22 is thereby switched to the playback amplifier 24 side. and the selector switch 26 is switched to the recording amplifier 27 side.

Then, the teaching material track (■>) side is in the playback state, and the generated sound track (■) side is in the recording state.

Further, when the repeat button (31) is pressed during the above-mentioned practice recording IIA (re-recording mode), the B-CPU 30 switches the changeover switches 22 and 26 respectively according to the tape position detected by the detection output from the audio detector 39. A switching control signal is supplied to switch each changeover switch 22, 26 to 1111.
At the same time, a control signal is supplied to the reel motor drive circuit 35 of the BTR drive 34 to control the rewinding operation of the teaching material tape by the reel motor drive circuit 35 and the reel motor 37.

Next, regarding the repeated learning operation in "pronunciation learning" of the device of the present invention, the flowchart in FIG. 4 and FIG.
) and (b).

When the recording button (31) is pressed to enter the practice recording state (re-recording mode) [Yes in step 51], the selector switch 22 is switched to the playback amplifier 24 side, and the selector switch 26 is switched to the recording amplifier 27 side. Then, the teaching material track (■) side enters the playback state, and the teaching material head 21
The text of the teaching material is played back [A in Fig. 7 (C)], and at the same time the generated sound track (■) enters the recording state, and the generated sound is recorded by the generated sound head 25 [7
B in figure (C)].

Next, in this re-recording mode (the teaching material track (■) side is in the playback state, the generated sound track (■) side is in the recording state), if the switch (31) is repeatedly pressed (turned on), the [Yes in step 52] is pressed. ], the end of the next blank period of the sentence in the teaching material track (■) (that is, the beginning of the next sentence) is detected by the audio detector 39, which detects the sentence period and blank period of the teaching material track (■). Then, [Yes in step 53], that is, when the waveform rises in the detection pulse shown in FIG. This reel motor drive circuit 35 and reel motor 37
The teaching tape will be rewound. Then, when the teaching material tape is rewound to the beginning of the sentence immediately before the blank period, rewinding of the teaching material tape is stopped [step 55].

Here, in order to rewind the teaching material tape to the beginning of the sentence immediately before the blank period, when the beginning of the sentence is detected by the detection pulse (its waveform rise), the tape position at that time (tape counter value) By storing this in the memory 32, when the current tape position (tape counter 1M) matches the tape position (tape counter value) stored in the memory 32 at the time of rewinding, it is determined that the rewind has been made to the beginning of the sentence. , stop rewinding.

As mentioned above, it becomes "re-re-mode" and B-Cp U
A switching control signal is supplied from 30 to the switching switch 26,
The changeover switch 26 is switched to the reproduction amplifier 28 side.

Then, the sound generation track (■) side will be in the playback state,
The generated sound is reproduced by the generated sound head 25 [step 56].

Note that the changeover switch 22 remains switched to the playback amplifier 24 side, and the text of the teaching material is played back by the teaching material head 21 while the teaching material track (■) side remains in the playing state [as shown in Fig. 7(C)]. C.D.I.

Also, in step 53, when in the "re-recording mode",
If the blank period following the passage with the teaching material track (■) continues for a long time and the blank period does not end immediately (for example, if the blank period between units or if all the sentences in the teaching material have finished), the step At 54, timer 33
Based on the time count, it is determined whether the blank period has continued for a certain period of time (for example, a period that is slightly more than twice the length of the immediately preceding sentence (sentence period)), and if the blank period has continued for more than a certain period of time [Step 54 Yes], the process moves to step 55, where the teaching material tape is rewound to the beginning of the sentence immediately before the blank period as described above, and the "replay mode" is entered [step 56].

Next, in step 56, the "re-re-recording mode" is entered, the teaching material track (■) is being played, the generated sound track (■) is also being played, and the teaching material track () is being played in the same manner as in the above-mentioned "re-recording mode". ■) The end of the next blank period in the sentence with (
That is, when the beginning of the next sentence is detected by the voice detector 39 [Yes in step 57], the teaching material tape is similarly rewound to the beginning of the sentence immediately before the blank period.
Step 59], the selector switch 27 is changed over, and the mode is again set to "re-recording mode J" [Step 60].

Also, in step 56, when in the "re-re-mode",
If the next blank period of a sentence with a teaching material track (■) continues for a long time and the blank period does not end immediately, it is determined in step 58 as in step 54 whether the blank period has continued for a certain period of time or more, and If it continues [Yes in step 58], the process moves to step 59, where the teaching material tape is rewound to the beginning of the sentence immediately before the blank period as described above, and the "re-recording mode" is entered [step 60].

Then, return to step 53 again, and step 53~
The operation of one cycle up to step 60 is repeated.

Although not shown in the flowchart of FIG. 4, after one cycle of operations from step 53 to step 60 is repeated about 10 times, the repeated learning operation in "pronunciation learning" of the device of the present invention starts. finish.

The number of repetitions of the cycle from step 53 to step 60 in the flowchart shown in FIG. 4 may be arbitrarily selected depending on the level of the learner.

As described above, the repeated learning in "R pronunciation learning using the device of the present invention" is as shown in Figure 3, by playing and listening to the text of the [A] teaching material, and then using it as a model.
[,B] After recording your own voice (generated sound) and rewinding the tape, [C] Play and listen to the same sentence from the teaching material again, and then [D] Listen to the voice you recorded. You can repeat a cycle of playing and listening to the generated sounds and comparing them with the model teaching material, and for each cycle you can re-record your own voice (generated sounds) and learn how to use them. Play and listen to it, compare it with the text in the model teaching material (i.e., the pronunciation that was played), and then record the voice (generated sound) that you have pronounced yourself (the generated sound). You can repeat the process of revising the material and comparing it with the model teaching material, making it possible to carry out the most effective repeated learning.

(Effects of the Invention) As described above, in the language learning tape recording and reproducing apparatus of the present invention, when the blank period of the first track ends or the blank period of the first track continues for a certain period or more during the re-recording mode, the blank period of the first track continues for a certain period or more. The teaching material tape is rewound to the beginning of the sentence immediately before the period, and then enters the replay mode, and at this time, if the blank period of the first track ends or the blank period of the first track continues for a certain period of time,
The teaching material tape is rewound to the beginning of the sentence in the blank period, and then goes back to re-recording mode, making it possible to use the most effective learning method for repeated learning in ``pronunciation learning.'' Therefore, we can expect great results in the learning effect of speech practice in language studies.
