When the reproducing machine 3 stops itself by signal inputted from the external during reproducing or stops itself by a signal generated by itself during reproducing, the recorder 2 is not immediately started only by said condition, the recorder 2 can be started at an optional time without executing complex operation and recording and reproducing can be additionally continued.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording/playback system and device comprising a recorder and a playback device, and particularly to a CAT learning machine.

All student voices are captured by the CAI system, which captures students' voices when giving instructions for playing narration sounds, etc.
There is a strong desire for interactive CAI that uses audio as a medium, in which each student is recorded and the teacher then corrects the audio.

However, with conventional recording and playback methods and devices, for example, in the case of tape-based narration, there are many waiting time gaps in the narration, which limits the total study time for the first volume, and there are periods when there is no utterance during recording. As a result, it took extra time to play the recording.

Therefore, after recording, the recorder is stopped immediately and the playback device is started immediately, but when the playback device is stopped, the recorder is not started immediately.
This function is required. For this reason, the configuration shown in FIG. 1 has conventionally been used.

When the three-contact switch 12 is in the A position and the open/close switch 13 is closed, the recorder 2 is started and the player 3 is stopped. After recording with microphone 5, etc., open 13.

And by setting 12 to position B, 2 stops and 3 starts. To stop 3, set 12 to A position, and then close 13 to start 2. This conventional method required 7M sloppy switch operations and was particularly unsuitable for young students.

The method and device of the present invention uses a recorder that operates only when recording is necessary, such as a G5 machine equipped with existing technology such as a remote switch and voice operation mechanism, and stops the recorder. - or when the material is paused (hereinafter also referred to as "stop"), the player is simultaneously started or released from the pause (hereinafter both are referred to as "start"), and the player is
For example, when the recorder stops by an external signal input during playback, or by a signal generated by itself during playback, the recorder does not start immediately with this alone, but can be used at any time and in a complicated manner. It is characterized in that it can be started without any manual operation, and recording and playback can each be continued additionally.

This will be explained below by giving an example.

FIG. 2 shows an example of a voice correction CAI recording/playback device and its peripheral system according to the present invention.

The recording/playback device 1 includes a recorder 2, a playback device 3. It consists of a controller 4 including a power source, etc., a microphone 5 is input to 4 and 2, and a remote control switch 6 is input to 4, respectively. 1 is connected to a personal computer 7 and CR'r 8, and further connected to a voice mail station 10 via a telephone 1119. For 2, use a tape, T, SI, etc. player.

isk FIG. 3 shows an example of the controller 4.

The microphone human-powered sound wave 21 passes through a voice operation 23 using conventional technology, and becomes a waveform 24 whose level is 1-1 only while the sound wave is present, and the recorder start/stop circuit 26
, generates an output 27 that starts level H and stops level L, and controls the recorder 2. Instead of 21, the waveform 24 may be generated by the remote control switch 6. The waveform 24 is generated by the differentiating circuit 28 as a pulse A corresponding to the start point of the sound wave or the closing of the switch a, and a pulse A corresponding to the end of the sound wave or the opening of the switch. The waveform becomes 29 with the corresponding pulse B, and after using the limiter 30 to make only the pulse 83.1, 31 is manually applied to the regenerator flip-flop 35 as a start pulse, and the regenerator start/stop circuit 36 is driven to set the level H. A starting output 37 is generated to start the regenerator 3. Alternatively, when using a CD player, a start signal is input to the control system of the laser disc. On the other hand, control signal sounds are recorded at necessary locations on the tracks of the playback disc or raw tape, and when the playback machine generates this signal sound 32 during playback, the limiter 33 with a differentiating circuit pulses the rising part d. A wave 34 is input to the flip-flop 35 as a stop pulse.

Thus 31. Starts at level H at input A, and eventually reaches 3
37, which becomes level L and becomes a stop, is formed by the human power of 4. 23, 26, and 36 can be configured with relays or the like.

That is, as soon as the necessary narration is finished, the player records it, and stops immediately when the remote control switch is turned off or the sound waves end. The playback device starts immediately in conjunction with this stop, and the recording of the narration and vocalizations proceed extremely smoothly and without waste. In other words, if you stop the recorder, it will immediately start the playback, but vice versa.

Even if the playback device stops, the recorder does not start immediately. This function can be realized without complicated PJ/PJ switch operations.

As a result, since the recording is stopped while the student does not speak, the blank time of the recording can be shortened, and the playback time required for the teacher to correct and grade can be significantly shortened. In particular, when recordings are sent to a voice mailbox, the call time can be shortened, and the cost reduction effect is significant.

Furthermore, since the narration also stops at the blank time in the middle, for example, when creating a narration tape, there is no blank section.
You can fill it up and edit it. As a result, a considerable length of blank space is provided only between lessons, and it is possible to easily find the beginning of a lesson by cue review or the like. Furthermore, various effects can be realized by combining it with a screen and computer processing.

In addition, students can freely decide the amount of time until they start recording after the narration is finished, making it ideal for individual learning.Thus, with the present invention, it is possible to edit by compressing blank areas for both recording and playback. Moreover, the cooperative operation of both recording and playback can be realized at once, and continuous recording and playback of an additional type becomes possible.

In addition to cassette tapes, the recorder also accepts DAT, LSI memory, discs, pre-loaded cards, video tapes, and magnetic disks. , C
D-ROM, CD-ICD-V, pre-loaded disk, preloaded card, magnetic disk, etc. can be used arbitrarily. This includes the magneto-optical method.

FIG. 4 shows an example of a CAI system in which a CD-1 or a CD-ROM is incorporated into the device of the present invention. 40 (referred to as a ROM device) is executing an educational curriculum, one screen is being displayed on screen 8, and an audio narration is being provided. Eventually, students will be encouraged to speak where necessary, and the audio narration will pause.

Immediately or after preparation work, if the student inputs a vocal sound from the microphone 5, the activated recorder 2 will record the microphone input sound wave 21, while the same input sound wave 21 will be shaped by the controller 4 and then converted into a signal. 41 is also human-powered, and as a result, one voice that controls changes in the operation of the screen and curriculum is completed, and at the same time as recorder 2 pauses, 4 sends a signal to 40 to activate 40, and the voice narration resumes.

Implementation of the educational curriculum progresses. When the curriculum is completed in this way, the tapes, disks, and LSI memory 42 containing all of the student's vocalizations will be completed, and since they are dense recordings with no unnecessary blank spaces in the middle, this audio can be used by the teacher. It is extremely efficient when playing back for correction, that is, for audio correction. Moreover, it can also be used when sending voice mail etc. to a distant teacher who will perform audio corrections on the recorded content.

Communication time and costs can be saved.

The above-described operation and pause of the recorder can be performed by a voice operation mechanism, a remote control switch, or other means, all of which require very simple operations, so even young students can use it without error.
