JPH03238518A - Audio output keyboard device - Google Patents

Abstract

PURPOSE:To eliminate a need to confirm an inputted character on a screen by outputting the character inputted from a keyboard with sound to discriminate whether it is correctly inputted or not by hearing. CONSTITUTION:When an audio output command is indicated from a keyboard 11, the audio output function is operated to set the sound output permission state. The sound to be outputted are assigned to all of individual keys on the keyboard 11. An audio output keyboard part 20 produces sound of alphabets, KANA (Japanese syllabary) characters, and numbers, and a mode switching device 21 of the audio output keyboard 20 judges whether the present input mode is the alphanumeric and symbol input mode or the KANA character input mode. A sound converter 24 receives various character information as a code from an alphanumeric and symbol recognizing device 22 and a KANA character recognizing device 23 and determines the classification of sounds, a scale, the width of sounds, etc., based on these information to transfer them to a voice output device 25. Thus, input is confirmed with sounds.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a computer input method, and particularly to a keyboard input method using a keyboard.

[Conventional technology]

A keyboard input method is a computer peripheral device and an input device. In the keyboard input method, input is performed by pressing the keyboard. When inputting by pressing down on the keyboard, the user visually checks the characters displayed on the screen to confirm whether the input characters are entered correctly.

[Problem to be solved by the invention]

In the conventional keyboard input method described above, when inputting a document using a keyboard, the characters displayed on the screen must be visually checked to confirm whether or not the entered sentences and characters have been entered correctly. are doing. Therefore, when inputting from a keyboard, the user must input while looking at three things: the screen, the document, and the keyboard. Therefore, there is a drawback that it takes a lot of time for confirmation during input work.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate such drawbacks and provide a voice output keyboard device that allows input to be confirmed by voice.

[Means to solve the problem]

The voice output keyboard device of the present invention includes a keyboard input means for inputting characters by pressing a key, and when the characters from the keyboard input means are alphahets and numbers, the character is pronounced at the same time as the input, and a kana character mode is set. In the case of Roman alphabet input, the system is characterized by having an audio output means that produces sounds using a combination of vowels and consonants.

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

FIG. 1 is a configuration diagram showing an embodiment of the present invention. 1st
The voice output keyboard device shown in the figure is composed of a keyboard section 10 and a voice output keyboard section 20.

Further, the keyboard section 10 is a CRT (Cathode
raytube) device 11 and a keyboard 12.

The voice output keyboard section 20 includes a mode switching device 21
, alphanumeric/symbol recognition device 22, and kana character recognition device 2
3, a voice conversion device 24, and a voice output device 25.

In the voice output keyboard device having such a configuration, the CRT device 11 of the keyboard section 10 displays input characters and the like.

The keyboard 11 is similar to a normal keyboard. When a voice output command is issued from the keyboard 11, the voice output function is activated and the voice output becomes possible. Furthermore, sounds to be output are assigned to all keys on the keyboard 11.

The voice output keyboard unit 20 pronounces alpha characters, kana characters, and numbers.

The mode switching device 21 of the voice output keyboard section 20 determines whether the current input mode is an alphanumeric/symbol input mode or a kana character input mode.

All characters and numbers entered from the keyboard 12 are treated as codes. If it is determined that the input code is a code indicating the kana character mode, the mode becomes the kana character mode from that point on, and the next character to be input is passed to the kana character recognition device 23. Before the code indicating Kana character mode is input or when the code indicating canceling Kana character mode is input, the mode becomes alphanumeric/symbol mode.
The input character code is passed to the alphanumeric/symbol recognition device 22.

The alphanumeric and symbol recognition device 22 receives alphanumeric and symbols as input. In this alphanumeric/symbol recognition device 22, the second
Uppercase letters, as shown in figure (a).

There is a function to judge lowercase letters, full-width, and half-width by code. This alphanumeric/symbol recognition device 22 is
The input code is passed to the voice conversion device 24.

The kana character recognition device 23 receives kana characters as input.

Then, in this kana character recognition device 23, as shown in FIG.
As shown in , Kana input, Romaji input judgment,
It has the ability to judge full-width, half-width, hiragana, and katakana characters based on the input code. In the case of kana input, since the kana character code is input as is, it is passed to the voice conversion device 24. In the case of Romaji input, the two-letter code of a vowel and a consonant is converted into a kana character code and passed to the voice conversion device 24.

The voice conversion device 24 receives various character information as codes from the alphanumeric/symbol recognition device 22 and the kana character recognition device 23, determines the type of sound, scale, width of the sound, etc. based on the code, and converts the sound into a voice. It has a function of passing it to the output device 25.

The audio output device 25 receives the information converted by the audio conversion device 24 and outputs it as audio.

Next, the operation of this voice output keyboard device will be explained.

In kana character mode, Roman alphabet input, when entering "ma" in full-width characters, the user presses the keyboard 12, enters "m", and then enters "'a゛°.The keyboard 12 inputs these characters. is sent to the mode switching device 21. The mode switching device 21 determines that it is the kana character mode, and sends the first input character “m” to the kana character recognition device 23.

The kana character recognition device 23 first determines whether the input is kana or romaji, and then also determines whether it is full-width, half-width, hiragana, or katakana. Since I am currently inputting Romaji, I wait for the vowels to be input.

Next, "a"° is input from the keyboard 12.

Then, because of the above conditions, the character "a" passes through the mode switching device 21 and is sent to the kana character recognition device 23. Here, the character "m" that was input last time is waiting. Since the vowel-consonant relationship holds true for the letters “m” and “a”, they are converted into the Mapa code.And,
This "'ma" code and the full-width and hiragana information are sent to the voice conversion device 24. The speech conversion device 24 determines the type of sound and musical scale from the input characters "ma" and the information on full-width and hiragana, and sends them to the speech output device 25.

The voice output device 25 receives the information from the voice conversion device 24 and pronounces ``゛ma゛''.

When using such a voice output keyboard device, no matter how fast a person can hit the keys, he or she cannot keep up with the speed of human speech, so the voice will not follow behind the keyboard input. Therefore, this voice output keyboard device, when the keyboard is pressed,
The pressed keys can be converted into audio and output.

(Effects of the Invention) As explained above, the present invention outputs the characters entered on the keyboard audibly, so that it is possible to judge by hearing whether or not the characters have been entered correctly. There's no need.

As a result, you can concentrate on the manuscript at hand, make fewer mistakes (and be able to type quickly on the keyboard).
