Description

[Detailed Description of the Invention] The present invention enables visually impaired people and young children who cannot read a single letter to practice Braille and letters by simultaneously perceiving Braille and letters and their sounds. This invention relates to a learning device that allows characters to be easily memorized.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In Figures 1 and 2, 1 is a case that constitutes the main body of the device, 2 is a power on/off knob with a volume control, 3 is a sound emitting hole, and 4 is a hiragana character from "a" to "n" and "ga".
Multiple keyboards for pronouncing voiced and semi-voiced sounds such as "ba", 5 is "ya".

A keyboard 6 is used to input lowercase letters such as ``yu'' and ``yo'', and a keyboard 6 is used to generate sounds including diphthongs such as ``kya'', ``kyu'', and ``kyo''. And the above keyboard 4,
5, the letters corresponding to their respective pronunciations are displayed on the top surface.

Figure 2 shows its internal configuration, where 7 is an input device having keyboards 4 to 6, etc., 8 is an address counter driven by the output of input device 7, and 9 is a coded device necessary for speech synthesis. The signal is stored and the address counter 8
10 is a speech synthesizer that synthesizes an audio signal based on the coded signal from the storage device 9, 11 is an audio amplifier with a filter, and 12 is a speaker.

In the above configuration, for example, if you want to hear the pronunciation of "a", you can press "a" on the keyboard 4. In this way, a predetermined address of the storage device 9 is specified by the output of the address counter 8, and the “
The encoded signal necessary for synthesizing the voice ``A'' is output to the voice synthesizer 10. As a result, the speech synthesizer 10 outputs a speech signal for "a", which is amplified by the filtered speech amplifier 11 and produced by the speaker 12.

"i" to "bo" are pronounced in the same way.

In addition, in the case of a sound that includes a diphthong, such as ``kiya'', press keyboard 6 in advance to wait for pronunciation until two people have the strength, and press ``ki'' on keyboard 4 and ``ki'' on keyboard 5 in advance. Just press "ya" repeatedly. If you do this, you can press the keyboard of ``YaJ'' and at the same time press ``Kiya''.
sound is pronounced.

FIG. 3 shows another embodiment of the present invention.
Keyboard 13 and voiced sounds from ``n''.

Keyboards 14 and 15 representing semi-voiced sounds are provided, and keyboards 13 and 14 or keyboards 13 and 16 . Alternatively, by pressing keyboards 13 and 6 successively, a voiced sound or a semi-voiced sound can be produced.

Note that if Braille is provided on the front side of each keyboard instead of letters such as "a" and "i", the five braille characters and pronunciation can be perceived at the same time. Of course, you may use both letters and Braille, or you may use numbers instead of kana. Furthermore, three or more letters can be pronounced consecutively, and in this case, an accent adding keyboard is provided that increases the gain of the filtered audio amplifier 11 only when pronouncing the letters to be accented. It may be provided.

As described above, the present invention is designed to generate sounds corresponding to Braille or characters by pressing a keyboard on which characters or Braille are printed. Children learn Braille.

It is extremely convenient for learning the pronunciations of letters and characters, and since it can be learned repeatedly with simple operations, the learning speed can be significantly increased.
