Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a learning device comprising one parent; Regarding the learning value '+1 used.

[Summary of the invention]

This invention stores the audio Iha number in memory.

The control means for controlling this memory stores the start address and end address of each sentence unit in relation to the audio signal, and the start address and end address of each sentence unit of the audio signal stored in the memory are stored in accordance with specific operation information. By playing time sequentially? ! ? This allows you to quickly locate the beginning of each sentence (and play it back) with a simple operation.

[Conventional technology]

In a group language learning method generally referred to as the LL-system (Language Laboratory System), the main content is the repeated practice of basic fixed sentences.

To do this, first, duplicate tapes of the teaching material are created for each student, and each student plays these duplicate tapes on their own basis using LL-tape recorders placed for each student to practice language skills such as °ζEnglish conversation. method was adopted. Also,
LL-systems using memory as storage means (LL-systems using memory are disclosed in Japanese Patent Application Laid-open No. 59-129889 and Japanese Patent Laid-Open No. 59-2248).
It is publicly known from Publication No. 97, etc.

[Problem that the invention seeks to solve]

However, the recording and playback operation of a tape recorder is originally a so-called sequential operation that is performed along the magnetic tape, and when a student lazily selects a specific part of the teaching material and tries to practice, it is necessary to rewind or fast forward the tape. etc., it takes time to respond to the selection directly, especially when starting a sentence, it is difficult to bring out that part, and it is difficult to rewind, fast forward, or play back to hear the beginning of the sentence. It was necessary to do this, and the repetition was complicated.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a learning device with excellent operability that can quickly locate the beginning of a sentence and reproduce it with a simple operation.

[Failure to solve the problem]

The learning device according to the present invention includes a memo 1 for storing audio signals.
May 3) and control this memory as well as "Yuki audio (4)
control means (4, 5) for storing the start address and end address of at least 4) sentences in relation to the number, and operation means (8, 9) for generating operation information to the control means; The audio signal is configured to be sequentially reproduced for a predetermined period of time from the start address of each sentence unit of the audio signal stored in the memory based on specific operation information from the operation means.

[Effect]

Audio No. 14 is stored in memory (3). At the same time, the start address, end address, and pause time (silent period) are recorded in the control means (4, 5) for controlling the memory at the first position of the sentence fff in relation to the above-mentioned audio signal. The control means stores the start address and end address of each sentence in memory.
Therefore, only each sentence, that is, only the sound period, is written into the memory. Among the multiple keys included in the operating means, a specific key such as the forward scan key (
8) or when the negative direction scan key (9) is pressed, the control means changes the address for the memory in accordance with the operation information, and moves to the start address position of the sentence unit of the audio signal stored in the memory. As a result, it is possible to instantly move to the beginning of each sentence, and it is possible to sequentially reproduce the text from the beginning of each sentence for a predetermined period of time.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on FIGS. 1 to 4.

FIG. 1 shows the circuit configuration of this embodiment. In the figure, (1) is an input terminal to which the audio signal for the teaching material or the audio signal of the practitioner is supplied; The audio signal from the A/D converter (2) converts the analog signal into a digital signal. The A/D converter (2) is the audio supplied to the input terminal (1).
If the audio signal supplied to the practitioner is from the practitioner, it is included in the pre-recording.

The 1st signal converted into a digital signal from the A/D converter (2) is converted to a digital signal from the A/D converter (2), for example, by
) and a central processing bag Wl as a control means.
(hereinafter abbreviated as CPU) (4).

As shown in FIG.
Sn (sound period) and the pause time P that exists during that period
1 to Pn (silent period) to 1, 21st F-I
The beginning of each sentence is set to the start address B and the end of each sentence is set to the end address E, respectively, and the pause time P of each sentence is stored. That is, CPU 41 is a memory map similar to that shown in FIG. 3, which is formed in response to a manually inputted audio signal.

In FIG. 3, the start address of text number S1 is Bt,
The end address is El, the pause time is Pl, the start address of text number S2 is B2, the end address is B2,
The pause time is B2, and so on.

CPU (/11) sets the start address and end address of each sentence from the memory map in the memory controller (5), and a counter (not shown) in the memory controller (5) counts up from the start address to the end address. The corresponding address signal is transferred to the memory (3
), and the audio signal from the A/D converter (2) is written in units of sentences at the predetermined position of the memo 3) specified by the address signal. Therefore, only the audio signal corresponding to the start address to the end r address of each sentence is written in the memo January 3), and the pause time is removed. The pause time is counted by a counter (not shown) in the CPU (41).
The PU (4) and memory controller (5) are housed in the main body.

(6) is a D/A converter to which the audio signal read from the memory (3) is supplied during playback, where the digital signal is converted into an analog signal and taken out to the output terminal (7). D/A converter (6) is A/D converter (2)
It is included in sharps or pre-fills correspondingly.

(8) and (9) are a forward direction scan key and a negative direction scan key, and of the plurality of operation keys, only those related to the present invention are representatively pressed here. These keys may also be used as a fast forward (FF) key and a rewind (REW) key. These scan keys f81. When +91 is pressed, the start address of each sentence unit of the alpha audio signal is specified as described in the memo January 3) as described later, and each sentence is struck out for a predetermined period of time, for example, several seconds. H generated functions are achieved. (1o) is a display that displays text numbers and the like.

Note that the scan keys +81 and +91 are included in both the sharp instrument and the prefill, and the display (1o) is included in the sharp instrument.

During playback, when the play key is pressed (not shown), the CPU
f4), the start address and end r address of the first sentence at that point are sent to the memory controller (5), and the internal counter counts up from the start address of the sentence, so that the corresponding address signal is sent to the memory controller (5). ), the audio signal of the corresponding sentence written in a predetermined position in the memory (3) is read out, and
The signal is taken out to the output terminal (7) via the /A converter (6).

Then, the count value of the counter of the memory controller (5) ends. When it becomes equal to the address value, the address signal that was being supplied from the memory controller (5) to the memo 1/3) is stopped. Also memory controller (5)
When the count value of the counter becomes equal to the value of the end address, this is transmitted to the CPU (41), and from that point on, the counter in the CPU +41 counts up.Then, the pause time of the corresponding sentence is When the time period elapses, the count amplifier of the counter in the CPU [4] is stopped, and at the same time, the start address of the next sentence is set in the memory controller (5). Thereafter, the same 41 works as described above are repeated. Therefore, the output terminal (7
), similar to the audio signal supplied to the input terminal (1), an audio signal with a pause time (silent period) after each sentence is reproduced.

Now, in the present invention, it is possible to achieve the function of locating the beginning of each sentence and sequentially reproducing it for a predetermined period of time.The operation will be explained with reference to the fourth IgI4:.

The program starts in step (A), and in step (B), the CPU (4) determines whether or not the scan key has been pressed. The pressed scan key is either the forward scan key (8) or the negative scan key (9). If it is the forward scan key (8), the process proceeds to step (d).

In step (d), the CPU +41 executes the start address of the text number next to the current text number (if the address was missing between the start address and the end address of the current text number at the time the key was pressed) If you do this, the forward mode (FF
'Move to the start address of the next text number) and set it in the memory controller (5).

The start address of the next document number is the memory controller (5
), the counter in the memory recontroller (5) counts up in step (e), the corresponding address signal is supplied to the memory (3), and the memo January 3
) (the start address position of the text number corresponding to the IT issue is specified. Then, from Memo January 3), the sound 1. corresponding to the next text number is specified. A number is read out, D
/II converter (6) to output terminal (7).

In step (g), the CPU (4) determines whether a predetermined time, for example, several seconds, has elapsed or not. If not, it waits until the predetermined time has elapsed, and when the predetermined time has elapsed, the process advances to step (g) and stops the reproduction operation.

Then, if you press the forward scan key (8) again, the same operation as above will be repeated and the next sentence will be played. If you keep pressing the forward scan key (8), each sentence will be played one after another in the forward direction. Only the beginning of the sentence is continuously played back for a predetermined period of time.

If the negative direction scan key (9) is pressed in step (c), the process advances to step (h), where the CPU (4) reads the start address of the current sentence number (at the time the key is pressed, the current sentence number 1flf If there is an address failure between the start address and end address of
, corresponding to W mode), so move to the start address of the current text number) is set in the memory controller (5).

The start address of the current document number is set to the memory controller (
5), the counter in the memory controller (5) counts up in step (su), and the corresponding address signal is supplied to the memory (3).
), the start address position of the corresponding sentence number of the audio signal a is specified. Then, the audio signal corresponding to the current text number is read out from the memory (3), and the D/
It is taken out to the output terminal (7) via the A converter (6).

In step (N), it is determined whether a predetermined time, for example, several seconds, has elapsed. If not, the process waits until the predetermined time has elapsed, and when the predetermined time has elapsed, the process advances to step (R) to stop the reproduction operation.

And in this case, even more negative direction scan key(?)
When you press , the same operation as above is repeated and the sentence before the current sentence is played, and the negative direction scan key (
If you keep pressing 9), only the beginning of each sentence will be continuously played back for a predetermined period of time in the negative direction.
