The character input method in the JIS layout keyboard 10 is an input method that does not have a character conversion function (a method that directly displays the meaning of the key by key input) and an input method that has a character conversion function (multiple key input). It is divided into a method of converting into cu or the). Then, in the case of the input method having no character conversion function, the character / symbol key can display a maximum of four groups of characters and symbols by combining a kana key and a shift key, as shown in FIG. That is, when pressing the key without pressing either the Kana key or the Shift key, the first group (A) consisting of specified lowercase letters, numbers and symbols, and when pressing the key while holding down the Shift key without locking the Kana key, The second group (B) consisting of English letters and symbols of the large letters, and the third group (C) consisting of predetermined Japanese letters and symbols when pressing the Kana key without locking the shift key and the Kana key When is locked and the key is pressed while pressing the shift key, characters belonging to the fourth group (D) consisting of predetermined Japanese characters and symbols can be obtained. However, depending on the combination of the Kana key and the shift key, there are keys that have no characters or symbols to enter. In the case of an input method having a character conversion function, it can be divided into Roman alphabet input (E) and kana input (F). Furthermore, this keyboard 10 has a so-called roll-over function that preferentially recognizes the key pressed later when two keys are pressed in a short time and continuously presses the same key for a certain time or more. It has a so-called auto-repeat function that is similar to the above.

The electric control device 30 includes a program ROM 30b connected to the bus 30a, a CPU 30c, a RAM 30d, an I / O 30e, an audio output method switching I / O 30f, an audio switching control circuit 30g, an audio ROM 30h, an audio synthesis I / O. An O30i and a voice synthesis circuit 30j are provided. The program ROM 30b stores the computer program shown in FIG. 3, the CPU 30c executes the program, and the RAM 30d temporarily stores variables necessary for executing the program. The voice switching control circuit 30g designates the address of the voice ROM 30h which voice quality should be used according to the analysis result of the key data from the CPU 30c. The voice ROM 30h has a male voice of the first group (A), a male voice of the child of the second group (B), a female voice of the adult of the third group (C), and a fourth group (the fourth group of the system having no character conversion function. D) is stored in a predetermined address as a voice of female voice quality of a child, and a Roman character input (E) of an input method having a character conversion function is used as an adult male voice, and Kana input (F) is a voice voice of an adult female voice. Is stored in a predetermined address as the above, and the sound quality signal stored in the predetermined address is output according to the address designation signal from the voice switching control circuit 30g. The unit length of the sound quality signal stored in the voice ROM 30h is set to about 0.2 seconds, and the unit length of the voice signal is equal to or longer than 5 unit lengths like symbol keys and function keys. For, the maximum is 1 second. Each sound quality signal is stored between a predetermined start address and end address. The selection of the length of the sound quality signal takes into consideration the key input speed of the practitioner and the rollover function and the auto repeat function of the keyboard, but it can be changed as necessary.

The voice synthesis circuit 30j demodulates the voice data selected by the character / symbol signal input from the CPU 30c through the voice synthesis I / O 30i and the selected sound quality signal input from the voice ROM 30h into an analog signal, and further The voice signal obtained by amplifying the analog signal is output to the amplifiers 41 and 51, and the end of the voice synthesis processing is output to the CPU 30c through the voice synthesis I / O 30i.

The I / O 30e is connected to the keyboard 10 and the display personal computer body 60, and inputs a key signal from the keyboard 10 and outputs a key signal to the word processor 60. However, the personal computer main body 60 is used auxiliary when it is desired to visually confirm the contents of key input. A voice output method switching switch 20 is connected to the voice output method switching I / O 30f, and an input method having a character conversion function or an input method having no character conversion function is selected depending on the switching of the switch. You have a choice. Further, the speaker 40 and the earphone 50 are connected to the output side of the voice synthesis circuit 30j via the amplifier circuits 41 and 51. Volumes 41a and 51a are attached to the amplifier circuits 41 and 51, respectively, and the audio signal from the audio synthesis circuit 30j is amplified by adjusting the volumes 41a and 51a, and the speaker 40 and the earphone 50 are amplified. Is output as voice from at least one of the above.

Next, the operation of the embodiment configured as described above will be described. By turning on a power switch (not shown), the CPU 30c of the electric control device 30 starts the program shown in FIG. 3 in step 100, and in step 101, performs initialization processing of various variables. Also, by turning on the power switch and appropriately switching the voice output method changeover switch 20, either one of the voice output methods having the character conversion function is selected. Then, the CPU 30c determines whether or not a key is pressed at step 102. When the practitioner starts inputting on the keyboard 10, the CPU 30c shifts the program to step 103 based on the determination of “YES” in step 102, inputs key data in step 103, and further in step 104. Executes the processing of the key data analysis routine. That is, in the case of the system having no character conversion function, the CPU 30c determines the content of the key pressed as it is in response to the key input, and the key is in any group of (A) to (D). It is determined whether or not the appropriate character / symbol signal is output. Further, in the case of a system having a character conversion function, the CPU 30c determines the contents of the key pressed according to a plurality of key inputs, and also determines whether it is the Roman character input (E) or the kana input, and the proper character writing is performed. No. signal is output.

Then, the CPU 30c determines in step 105 whether or not audio output is requested. That is, it is determined whether or not one key input corresponds to one voice, depending on the method having no character conversion function and the method having the character conversion function. When voice output is not requested, the CPU 30c returns the program to step 102 based on the determination of "NO" in step 105, and performs the process of the following steps. When voice output is requested, the CPU 30c advances the program to step 106 based on the determination of "YES" in step 105, and the contents of the pressed keys are (A) to (F). Select the address of the corresponding audio ROM according to which group of the above. Then, in step 107, the CPU 30c causes the voice synthesis circuit 30j to perform the process of the voice output routine shown in FIG.

The voice synthesizing circuit 30j starts the processing of the voice output routine at step 110 shown in FIG. 4, initializes the address at step 111, and then at step 112, outputs the desired sound quality signal to the voice ROM. Set the address stored in. Then, the voice synthesizing circuit 30j inputs the sound quality signal selected and output from the voice ROM 30h in step 113, and inputs the character symbol signal selected and output by analyzing the key data through the voice synthesizing I / O 30i. Further, the voice synthesizing circuit 30j demodulates the voice data input in step 114 into an analog voice signal, amplifies the voice signal demodulated in step 115, and outputs the voice signal amplified in step 116. .. The unit length of the voice signal is set to about 0.2 seconds as described above, and 1 second is set for the voice signal having a length of 5 units or more. The output voice signal is amplified by the amplifier 41 and is output from the speaker 40 as a voice having a sound length of 0.2 second to 1 second. The practitioner can accurately recognize the content of the key he or she pressed with this voice.

Then, the voice synthesizing circuit 30 j shifts the program to step 117 to change the address by adding “1” so that the next addressing can be dealt with. Determine whether or not. If it is not the end address, the program is returned to step 112 and the processing from step 112 to step 118 is repeated. When the end address is reached, the voice synthesizing circuit 30j ends the process of the voice output routine in step 119. Then, the CPU 30c further repeats the processing from step 102 to step 108 described above.

As described above, the practitioner can easily recognize the contents of the key pressed by the auditory sense by the sound generated for a certain period of time, and can practice the key input with the optic nerve free. Since you can do it, you can practice key input naturally and naturally, and you can learn key input in a short time.

In the above embodiment, the adjustment of the voice length is adjusted when the sound quality signal is stored in the voice ROM 30h, but the CPU 30c may perform this adjustment. Further, in the above embodiment, the personal computer main body is used for visual confirmation, but it is also possible to use the word processor main body instead.
