Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an instant confirmation learning/playback device used for language learning using recorded audio tapes.

(Prior Art) Repetitive learning is essential for language learning. With conventional language learning playback devices using audio tapes, it is necessary to rewind and play back the played sections when repeating learning.

Furthermore, when learning a two-part Japanese language, conventional learning/playback devices that support two-part language only have the function of playing only one selected channel or playing both channels at the same time. Therefore, in order to check the content of one language in a different language, you have to rewind the part that was played on one channel and switch to another channel and play it back, which means that you cannot check it immediately. There was a problem.

(Problems to be Solved by the Invention) The purpose of the present invention is to solve the problem of conventional devices that it is not possible to immediately confirm the playback location, and to arrange the reproduced audio in a first-in, first-out memory of a certain capacity during playback. It is an object of the present invention to provide an instant confirmation learning and reproducing device that can read data from the memory and immediately reproduce it, thereby improving learning efficiency.

(Means for Solving the Problems) The apparatus of the present invention includes a reproduction means for reproducing audio recorded on a recording tape, and an analog audio signal for converting an analog audio signal supplied from the reproduction means into a corresponding digital audio signal. and digital conversion means.

storage means for storing the digital audio signal supplied from the analog-to-digital conversion means; and replacing the digital audio signal supplied from the analog-to-digital conversion means with the digital audio signal that has elapsed the longest time since being stored in the first means. and temporarily stop the operation of the reproducing means in response to a control signal supplied from the outside.
a writing/reading means for sequentially reading digital audio signals from the means for the longest elapsed time since storage; and a digital/analog converting means for converting the read digital audio signals supplied from the writing/reading means into corresponding analog audio signals. and audio output means for outputting the analog audio signal supplied from the analog conversion means and the analog audio signal supplied from the reproduction means to the digital as audio.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. The instant confirmation learning and playback device shown in Fig. 1 is a two-part Japanese language real-time confirmation learning and playback device, which includes a signal control section 1 that generates control signals for internal control based on various signals given from the outside, and a signal control section 1 that generates control signals for internal control based on various externally applied signals, and a two-part Japanese language real-time confirmation learning and playback device. Channel 1 (C
Reproducing section 2 outputs to channel 2 (CH2) and channel 2 (CH2)
Then, in response to the input of the channel 1 and channel 2 outputs from the playback section 2, an analog-to-digital conversion section (hereinafter referred to as A-D
(referred to as a conversion section) 4 and an audio output section 8; an A-D conversion section 4 that receives an analog audio signal and converts it into a corresponding digital audio signal; In response to the supply of the write start signal, the digital audio signal within a certain period of time is periodically rewritten in the memory 7 from the earliest stored content in response to the supply of the write start signal. A memory control unit 5 reads out the contents stored in the memory 7 in a first-in first-out manner, and a digital-to-analog conversion unit receives a digital audio signal and converts it into a corresponding analog audio signal.
(hereinafter referred to as D-A conversion section) 6, channel switching section 3 and D
-A conversion section 6; and an audio output section 8 which receives the audio signal from the A conversion section 6 and outputs the audio signal.

Next, four input signals supplied to this embodiment will be explained.

The "bilateral language switching signal" is a signal indicating which of the bilingual languages has been selected by the user, and can be generated depending on the state of the channel selection switch, and determines the channel to be stored in the memory 7.

1-Reproduction signal" is a signal generated when the reproduction switch is pressed during reproduction of recorded content, and indicates that reproduction is in progress, and activates the reproduction section 7 and starts writing to the memory 7.

1. Meaning confirmation signal is generated by pressing a confirmation switch, etc. when the user wants to confirm the audio information of the channel selected with the channel selection switch (e.g., English) with the audio information of another channel (e.g., Japanese). In response to this signal, the reproducing section 7 is temporarily stopped and reading from the memory 7 is started.

A "stop signal" is a signal generated by pressing a stop switch used to stop the device.

FIG. 2 shows a flowchart of this embodiment which operates in response to the various signals mentioned above.

The operation of this example will be explained with reference to FIGS. 1 and 2.

Press the playback switch to generate a playback signal and enter playback mode. In other words, the signal control section 1 supplies a reproduction start signal to the reproduction section 2 and a write start signal to the memory control section 5 in response to the supplied reproduction signal.

Reproducing unit 2 (i) Simultaneously reproduces the recorded contents in two Japanese languages, outputs them to channel 1 and channel 2, and supplies them to channel switching unit 3.

As an example, assume that channel 1 is English and channel 2 is Japanese, and the user is learning English phrases. In other words, let's take the case where a user speaks English and uses Channel 20 Japanese to check whether or not he or she has understood the meaning.

In the above example, channel 1 is selected by the channel selection switch, and a corresponding bipartite language switching signal is generated and supplied to the signal control section 1. In response, the signal control unit 1 supplies a channel selection signal to the channel switching unit 3, and the channel switching unit 3 supplies the English information output from channel 1 to the audio output unit 8, and the English information is output as audio. Output.

On the other hand, the channel switching unit 3 selects the Nippon Katsu information f, A which is the output of the channel 2 not selected by the channel selection switch.
-Supplied to the D converter 4.

The A-D converter 4 converts the supplied analog audio signal into a corresponding digital audio signal and supplies the digital audio signal to the memory controller 5.

Since the memory control section 5 has already been supplied with the write start signal, it temporarily stores the digital audio signal supplied from the A/D conversion section 4 in its internal buffer memory. A timing clock is separately supplied to the memory control unit 5 at regular time intervals, and the memory control unit 5 transfers the digital audio signal temporarily stored in the buffer memory to the memory 7 in response to the supply of the timing clock.

Thus, while the user is listening to the English content of Channel 1, the Japanese content of Channel 2 is stored in the memory 7.

The write operation to the memory 7 is performed by replacing the content stored in the memory 7 with the longest elapsed time with the content temporarily stored in the buffer memory. Therefore, the memory 7 always stores the contents of channel 2 that was reproduced within a certain period of time from the current point in time.

When the user presses the confirmation switch to confirm the meaning, a meaning confirmation signal is generated and supplied to the signal control section 1.

In response to the supply of the meaning confirmation signal, the "signal control section" supplies a pause signal to the reproduction section 2, and supplies a continuation start signal to the entire memory control section 5. The playback section 2 temporarily stops the playback operation in response to the supply of the pause signal.

The memory control unit 5 interrupts the write operation by supplying the successive start signal, and starts the read operation of the stored contents from the memory 7. The read operation is performed on a first-in, first-out basis, that is, the data are read out in the order of the longest elapsed time since they were stored in the memory 7.

The digital audio signal read out from the memory 7 by the memory controller 5 is supplied to the DA converter 6, converted into an analog audio signal, and supplied to the audio output unit 8.

The audio output unit 8 outputs the analog audio signal (Japanese content in this case) supplied from the DA converter 6 as audio.

In this way, the user can hear the English content and immediately confirm it with the Japanese content, and can also repeatedly read out the content of the memory 7 in response to pressing the confirmation switch. To restart the device, simply press the playback switch again.

To stop the operation of this device, press the stop switch to generate a stop signal, and in response to the supply of this stop signal, the signal control unit 1 sends a stop signal to the playback@S2 to stop the playback operation and control the memory. The operation of section 5 is also stopped.

In this embodiment, a two-part Japanese language instant confirmation learning/playing device was described, but the present invention is not limited to this.
Even in the case of only channels, it can be used for immediate repeated learning, and even in the case of bilingual languages, the two channels can be stored separately in memory and both can be learned repeatedly at the user's choice. can.

(Effects of the Invention) The present invention has the effect that by accumulating the latest audio information in the memory slot and immediately outputting the accumulated content, it is possible to perform immediate confirmation learning and improve learning efficiency.
