Abstract

PURPOSE:To practice an abacus alone without necessitating a reading out expert by selecting and reading out voice data stored in a storage medium at random, storing the fact in a memory means successively, and consecutively converting the stored voice data into a voice and outputting it. CONSTITUTION:A CD-ROM 2 is driven by a CD driving device 1, and voice digital data stored in the CD-ROM 2 is read out. At this time, a CPU 7 executes a control program stored in a ROM 8. The voice digital data read out from the CD-ROM 2 is selected and combined at random, and is stored in a RAM 9 as the data of one question. Then, the data of one question stored in the RAM 9 is consecutively transferred to a voice output circuit 10, converted into the voice, reproduced and outputted through a speaker 5. A replay calculated by the CPU 7 is displayed on a display 4 after finishing output. Thus, the practice of an abacus is arbitrarily carried out alone.

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for generating sound for asking arithmetic questions, which is suitable for asking arithmetic aloud or mental arithmetic questions, which are one of the basic exercises for improving arithmetic skills. It is related to the device.

[Prior Art] Conventionally, problems in arithmetic arithmetic and mental arithmetic have been posed using the physical voice of a person who is skilled in arithmetic arithmetic and reading aloud.

Another way to ask questions is to use a tape recorder.
A method is also known in which questions are recorded on a tape in advance and the tape is played back.

[Problems to be solved by the invention] However, in the case of the former method of asking questions using real voice, it requires an expert, so it is not possible to practice alone, and there is also a problem of discrepancies between the questions and answers due to misreading. There have been problems such as fewer people reading arithmetic aloud at abacus cram schools, schools, etc., and it has become difficult to do arithmetic aloud, which is the basis for improving abacus.

In addition, in the case of the latter method of asking questions using a tape recorder, it is possible to practice alone without an expert reading aloud, but the memorized questions are repetitions of the same content.
The movements of the practitioner's fingers become standardized, and the results of practice decrease.

In addition, it is not possible to solve the problem of difficulty in hearing due to the mixing of noise when recording problems on tape.

This invention was made in view of the above-mentioned circumstances, and by reproducing and outputting the audio of reading arithmetic, it is possible to ask a large number of different questions consecutively in clear audio without requiring an expert reading arithmetic. It is an object of the present invention to provide a voice generating device for asking arithmetic questions, which can also provide answers to each question.

Note that as a method for synthesizing and outputting speech for purposes other than arithmetic calculation, there is a technique disclosed in Japanese Patent Application Laid-open No. 197098/1983.

[Means for Solving the Problems] In order to achieve the above object, the sound generation device for asking abacus questions according to the present invention includes a syllable for starting the question, a syllable indicating addition and subtraction as necessary, and a syllable for ending the question. a data storage medium that stores voice data consisting of digital syllables, numerical syllables, and unit syllables; a storage medium drive that drives the data storage medium to read voice data; and a memory that stores the read voice data. means, a control device that controls the storage medium drive to randomly select and read audio data from the data storage medium and store it in the memory means, and audio data transferred from the memory means. and an audio output circuit that converts the audio into audio and outputs the audio.

Further, the sound generating device according to the invention described in claim 2 uses a compact disc (hereinafter, a CD) as a data storage medium.
(referred to as D) is used.

Furthermore, the voice generating device according to the invention described in claim 3, when reading data for one question from the memory means,
It is equipped with a means for calculating the data, obtaining an answer, and notifying the answer.

[Operation] According to the present invention, the data storage medium is driven to randomly select and read audio data stored in the storage medium, and sequentially store the audio data in the memory means. By continuously converting and outputting audio data to audio through an audio output circuit, it is possible to ask a large number of combinations of reading arithmetic and mental arithmetic problems without the need for a reading expert and without causing reading errors. possible,
You can practice abacus by yourself.

In particular, according to the invention described in claim 2, it is possible to ask questions using high-quality audio, which is a feature of CDs, so that the results of practice can be further improved.

Further, according to the invention described in claim 3, answers to questions that are randomly combined are obtained and the answers are notified, thereby making it possible to check the answers at the same time.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is an external perspective view showing an outline of a sound generating device for asking arithmetic questions according to an embodiment of the present invention. The device is integrated into the left half of the device casing 3.

The above CD-ROM 2 contains the syllables for starting the question for ``Nishiteha'', the syllables for adding and subtracting ``Additionally'' and ``Toriteha'', the syllables for ending the question for ``For 1 yen'', and `` It stores audio digital data consisting of syllables that read units such as ``billion, ten thousand, yen'' and syllables of four-digit numerical values (integers). Each of the above syllables was read aloud by an expert. Here, it is preferable to use audio compressed data as the audio digital data because the number of stored data can be increased and more questions can be asked.

4 is a display that displays the answers, 5 is a speaker that outputs the questions in audio, and 6 is a start button.These are appropriately arranged on the upper surface of the right half of the casing 3. It has a microcomputer system built into its body.

FIG. 2 is a block system diagram of a microcomputer system. In the figure, 7 is a central processing unit (hereinafter referred to as CPU) that constitutes a control device, 8 is a ROM in which a control program is stored, and 9 is a RAM. (random access memory), 10 is an audio output circuit, and these are connected to the display 4 and CD-ROM 2 via a data bus DB and a control bus CB.

In the sound generating device for asking arithmetic questions having the above configuration,
The CD-ROM 2 is driven by the CD drive device 1, and the CD
- Read out the audio digital data stored in the ROM2. At this time, the CPU 7 executes the control program stored in the ROM 8, randomly selects and combines audio digital data read from the CD-ROM 2, and stores data for one problem in the RAM 9.

Subsequently, the data for one question stored in the RAM 9 is continuously transferred to the audio output circuit 10, converted into audio, and reproduced and outputted through the speaker 5. After completing the question, the answer calculated by the CPU 7 is displayed on the display 4.

Next, a specific example of a control program for advanced users will be described with reference to FIGS. 3A and 3B.

At 5TART (start), by turning on the power switch (not shown), as shown in step St, the syllable for starting the question of ``I hope'', which is required at the time of the question, and ``100,000,000,''``10,000,'' and ``Yen'' are displayed. Audio data consisting of unit reading syllables for ``Nari'', question-ending syllables for ``R yen wa'', and syllables for ``addition wa'' and ``toteha'' that indicate addition and subtraction, respectively, as necessary, are recorded on a CD. -ROM2 to RAM9
Store in.

Next, in step S2, the user (an abacus practitioner) sets the start button 6, and in steps S3 to
As shown in step S7, one problem of numerical syllable data read from the CD-ROMZ and randomly combined is stored in the RAM 9.

Here, l represents the number of lines in one problem, that is, the number of numerical values to be added or subtracted, and j is the number of syllables in one line (the first syllable is 100 million, the second syllable is 10,000, and the third is ) representing each unit of 1, and in the example of FIG. 3, i
If exceeds 15, the process moves to the audio playback operation from step S8 onwards to execute the audio playback. Furthermore, if j exceeds 3 in step S4, 1 is added to i and the process moves to storing the syllable data of the next row.

Next, in step S5, a 4-digit random number (i, j) is generated by a random number generation program, and
In step S6, the block address on the CD-ROMZ of the numerical syllable data corresponding to the random number generated in step S5 is calculated.

Figure 4 shows a map of the numerical syllable data stored on the CD-ROMZ.The audio mode of this CD-ROM2 is stereo mode and consists of two left and right channels. The right channel (indicated by R) and the odd number syllable data are stored in the left channel (indicated by L). For example, "545" is stored as a 4-digit random number.
6" is generated, the audio data "5456" stored in the R channel with record number 2728 is read out.

In step S7, one piece of numerical syllable data is stored in the RAM 9 from the address of the numerical syllable data calculated in step S6 as described above.

By executing the above steps S5 to S7 three times, one line of one problem (for example, r54
5,643,719,820 yen) was stored in RAM9.

Furthermore, by executing this syllable data storage operation for one line 15 times, the audio data for one problem is stored in the RAM 9.
is stored in

Next, the process moves to step S8, and through the operations from step S8 to step S13, the audio data stored in the RAM 9 is sequentially reproduced and output from the speaker 5. Here, k represents the number of lines that have been reproduced, and first, in step S8, the audio data of "I hope" is reproduced and output.

Next, in step S9, the highest numerical syllable data in one line is reproduced, and then, in step S10, the unit syllable data of "billion" is reproduced and output.

Subsequently, in step Sll, the next numerical syllable data in one line is played back, and in step S12, the unit syllable data of "10,000" is played back and output. The lowest numerical syllable data of the minute is played and output.

Through the above steps S9 to 313, one line of one question is reproduced and output.

Next, in step S14, in the case of reproducing up to the 14th line, the audio data of "circle" is reproduced and output,
Returning to step S8, in the case of reproducing up to the 15th line, 1
The voice data of "In a circle" is played back, and the process moves to answer calculation and display operations from step 315 onwards.

From step 515 to step 518.

Answer from the selected 4-digit random number values for 15 rows (hereinafter,
(referred to as ins) is calculated, and the calculated ans is displayed on the display 4. Here, m represents the number of rows to be calculated.

That is, in step 315, the random number (m, l) is multiplied by 10 to the 8th power, and in step S16, the random number (m, l) is
, 2) times 10 to the fourth power, and in step 317, a random number (m, 3) is added to ins.

By executing the operations from step S9 to step 317 for 15 lines, the ins for one problem can be solved.
is determined and displayed on the display 4 in step 18.

By the way, in the above embodiment, the numerical syllable data is 4 digits, and the numerical syllable data and the unit syllable data are stored in the CD-ROM shown in FIG.
One numerical value is represented by reading from ROM2 and combining them appropriately, but unlike this, one numerical value is represented by a series of numbers and units, that is, a numerical value consisting of a series of numerical syllable data and unit syllable data. - It may be expressed as unit mixed syllable data and stored in the CD-ROM 2.

In that case, for example, add numerical data (not voice data) indicating the address number and its numerical value (315,872,340) to the numerical value/unit mixed syllable data of 315,672,340, Create data, store a large number of such data in the CD-ROM 2, generate an address using random numbers as in the above embodiment, and read out the numerical e unit mixed syllable data using this address. and store it in RAM9. In this way, in order to read out numeric values of 150 (15 lines), only 15 random numbers are required, instead of 45 in the above embodiment.

In addition, if the numerical/unit mixed syllable data for one problem (150) is stored in the RAM 9 at once, it is possible to
Since the AM9 is required, for example, if the numerical/unit mixed syllable data is stored two by two in the RAM9 and sequentially reproduced by the audio output circuit 10, there is an advantage that the RAM9 can be an inexpensive one with a small storage capacity.

In this way, when storing numerical/unit mixed syllable data in the RAM 9 for a portion (for example, two) of one problem, only the numerical data of the above 10 minutes of data is taken in, and the data for one problem is stored. (150) If an integration means for integration is provided, the answer can be easily obtained.

The flowcharts shown in FIGS. 3A and 3B above are control programs for advanced users, but R
Of course, depending on the memory contents of the OM, it can be applied to control programs for beginners and intermediate users.

Moreover, as a storage medium for audio data, a digital tape may be used instead of a CD.

Furthermore, as the means for notifying the answer, in addition to displaying it on the display, it may be possible to notify the answer by sound from the speaker 5.

In addition to the audio output circuit 10 that outputs audio data stored in the RAM 9 as audio, a printer that prints this data may be provided.

[Effect of the invention] As is clear from the above explanation, according to this invention,
Basic practice problems such as arithmetic aloud and mental arithmetic can be asked with a large number of different questions without requiring a specialist who is skilled at asking questions, so even one person can practice arithmetic at will. can. Moreover, not only will there be no misreading of questions, but the uniform sound quality and tone will allow questions to be asked in clear, easy-to-hear voices.

Further, according to the invention of claim 2, the use of a CD makes it possible to ask questions with high-quality audio, and the use of a small CD
Since it is possible to store a large amount of data in
A large number of questions can be asked just by preparing one CD.

Furthermore, according to the third aspect of the invention, it is possible to calculate and notify the answers to the questions in real time and check the answers, thereby further improving the results of abacus practice.
