Consequently, different data for voice synthesis are stored on the same storage medium and a determined voice synthesis system is selected with an external control signal; and corresponding voice data are read out and a voice synthesizing process is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a barcode-based learning device that uses barcodes to generate sounds and enhances the educational effect.

Conventional technology A barcode is read by an optical reading device such as infrared rays or visible light, and based on the data code obtained, the required audio data is extracted from the corresponding audio ROM and output as audio by a speech synthesizer. The audio was converted into audio, passed through a filter that cuts high-frequency noise, and amplified by an audio amplifier.

In addition, voice synthesis methods include PCM (Pulse Codem), which converts the original sound from analog to digital, stores it in a storage medium, and converts it from digital to analog (D/A conversion) during playback.
The ADPCM (Adaptive PCM) method compresses this to reduce the size of the audio storage medium, the PARCOR method synthesizes the characteristics of human voice through an electrical filter, and the FM (Freque
There is an FM sound source method that uses a sound source LSI to generate musical instrument tones and synthesize melodies.

Using these methods, learning devices have been developed that enhance the educational effect by combining sounds, letters, and music.

Among them, learning devices using voice memory, voice synthesis, voice generation devices, etc. are disclosed in Japanese Utility Model Application Publication No. 63-80583,
This method has been proposed in, for example, Japanese Patent No.-113179.

In addition, the audio data that serves as the learning data is stored in an external storage medium such as a memory card or memory cartridge, which is connected to the target textbook and specified by operation input using a barcode reader, switch, etc. The words were read out, synthesized into speech, and converted into sounds.

Problems to be Solved by the Invention In the conventional learning device described above, the learning pattern is determined by the text, and the stored audio data is outputted as voice according to the learning pattern, and the learning pattern is transferred to the device itself. The learning pattern is stored in a fixed storage means, and the learning pattern is set using an operation signal, and is controlled under the selected conditions.

In this case, if the number of text software increases and the voice synthesis methods and operation flows become diverse or complex, it will no longer be possible to deal with it with only predetermined learning patterns, and the built-in It becomes necessary to consider replacing the storage means and even the device itself.

Furthermore, it is extremely difficult to set all learning patterns to the initial specifications due to storage device capacity limitations and software limitations, and because the voice synthesis methods are different, the data storage media are independent of each other. This makes it impossible to read it in a textbook. In other words, the number of storage media becomes plural, which complicates the operation, and it becomes necessary to replace the storage media depending on the speech synthesis method.

Therefore, in the present invention, these different speech synthesis data are stored in the same storage medium, a speech synthesis method determined by an external control signal is selected, the corresponding speech data is read out, and the speech synthesis processing is performed. It is something that makes you do.

Means for Solving the Problems The present invention was made to solve these problems, and a barcode printed on a textbook is read by a barcode reader.

In a learning device that reads audio data corresponding to the audio data from an external storage means (audio data ROM), amplifies the speech synthesis output, and converts it into a predetermined sound, a learning pattern corresponding to the audio data is stored in a part of the external storage means. death,
Based on the designation of the barcode, the pattern data is transferred to a temporary storage device (RAM) built into the main body, and the device is controlled to operate according to the learned pattern.

According to this configuration, when a barcode printed on a textbook is read by a barcode reader, audio data and the corresponding learning pattern are read from the external storage means into the temporary storage device based on the designation of the barcode.
It works to generate sounds according to the learned pattern.

Example An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an external view of the barcode learning device of the present invention.

The barcode reader 2 connected to the unit 1 of the barcode-based learning device can read the barcode 4 printed on the textbook 3, and the audio of the specified data can be stored in an external storage device (audio data ROM).
) 6 and can be converted into speech by the speech synthesis means 8 to generate speech. A volume barcode 5 for volume adjustment is printed on the text book 3 of the barcode learning device unit 1.

FIG. 2 is a system block diagram of such a barcode learning device, and FIG. 3 is a flowchart showing the flow of its operation.

When the volume adjustment barcode 5 for volume adjustment is scanned by the barcode reader 2, the control element 13 reads the code of the signal, determines it as a volume adjustment signal, and controls the volume control circuit 7.

Thereafter, by scanning the barcode 4 printed on the learning textbook 3, audio data based on the required data is read out from the audio data ROM 6.

The control element 13 D/A converts the audio data read from the audio data ROM 6 using the audio synthesizing means 8 and outputs an audio signal. Since this signal still contains many high frequency components, it becomes noise and the sound quality is very poor. Therefore, the high frequency components are cut through the low pass filter 10.

When this signal is input to the volume control circuit 7, it is attenuated to the level of the audio signal determined by the value of the volume barcode 5 specified previously. This determines the volume that is input to the preceding audio amplifier 12.

On the other hand, the audio data ROM 6 stores not only audio data but also unique learning patterns corresponding to the audio data. The learning pattern data in the audio data ROM 6 designated by scanning the barcode 4 is stored in a temporary storage device (RAM) 9 built into the main body via the control element 13. The control element 13 converts the audio data of the audio ROW 6 into D/D based on the data in the RAM 9.
It converts A and converts it into audio.

The operation of this embodiment having the above configuration will be explained. When barcode 4 printed on textbook 3 is read by barcode reader 2, based on the specification of barcode 4,
Voice data and learning data corresponding thereto are read from the voice data ROM 6 into a temporary storage device (RAM) 9, and a voice corresponding to the learning pattern is generated.

Therefore, it corresponds to the learning pattern determined by the software 1- of the contents of the textbook 3, and even if the textbook 3 changes and the learning pattern changes, it becomes possible to respond freely.

Effects of the Invention By doing this, the learning patterns specified by the textbook are stored in advance in the external storage means, so there is no need to have a large-capacity fixed storage medium inside the main body of the device, and it also saves time. The degree of freedom to create and incorporate new software each time is greatly increased, and it can be said to be very effective in enriching the software of learning devices.

In the embodiment of the present invention, a ROM card was used as the external storage means, but it is of course possible to use something like a cartridge type ROM pack, and it can be sold together with the textbook or sold separately later. Since it is compatible with software, it is also possible to reuse back-issue textbooks.
