Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an input circuit for an information processing device, and particularly to an input circuit to which a voice recognition device is added.

With the recent development of information processing technology, technology for directly introducing information through voice has been developed and is being put into practical use. A typical example of such a speech recognition device is shown in FIG.

The model sound collected by the microphone 1 is amplified by the amplifier 2, and is supplied to band pass filters 3, 3, . . . for dividing the sound band into appropriate numbers, respectively. The audio signals that have passed through each of them are A-D converted 5 through a multiplexer 4, and are converted into each voice of the model audio, such as A, I, C, etc.
The unknown voices are stored in the pattern memory 6 in the form of reference patterns corresponding to E, E, etc., respectively, and the unknown voices are similarly A-D converted and compared with the reference patterns of each voice in the pattern memory 6. The voice of the reference pattern with the smallest difference is recognized as the unknown voice.

On the other hand, in a normal information processing device, calculation commands, processing data, etc. are most commonly introduced from the keyboard. An example of such an information processing device is shown in FIG. 10 is a central processing unit, 11 is a memory for storing programs and data for information processing, and 12 is an I/O device for introducing data into this information processing device and conversely for deriving processing result data, etc. A keyboard 13 is connected to the O port. Details of parts related to this keyboard 13 are shown in FIG. For example, four output lines O ₁ , O ₂ , O ₃ , O ₄ are led out from the I/O port 12, and in a matrix with these output lines, for example, four input lines I ₁ , I ₂ , I ₃ and I ₄ are provided, and key switches K, K, . . . are arranged at their respective intersections. As shown in FIG. 4, each output line O ₁ ,
Non-overlapping timing pulses t ₁ , t ₂ , t 3 , t ₄ are supplied from the I/O port ₁₂ to O ₂ , O ₃ , O _{4 ,} respectively, and which input lines I ₁ , I ₂ , Key switches K, K, . . . are identified depending on which timing pulse is obtained from I ₃ and I ₄ .

The present invention relates to an input circuit for efficiently connecting a voice recognition device to an information processing device having such a matrix type keyboard, and will be described in detail below.

The feature of the present invention is that, as shown in FIG.
The information is supplied to the computer and input to the information processing device. That is, as shown in FIG.
is provided with the same number of output terminals N ₁ , N ₂ , N ₃ , N ₄ as the number of input lines of the I/O port 12, and these output terminals are connected to each input line I ₁ , I ₂ , I ₃ , I ₄ and further connected to these terminals N ₁ , N ₂ , N ₃ ,
The configuration is such that pulses synchronized with the timing pulses _t1 to _t4 shown in FIG. 4 can be generated from _N4 in response to voice recognition. For example, when the voice recognition device 20 receives a voice signal corresponding to the key switch K' at the upper left corner of the keyboard 13, the voice signal is compared with a reference pattern and subjected to recognition processing as described above, and a timing pulse is sent to its output terminal _N4 . A pulse synchronized with _t1 is generated, and data is input in exactly the same way as when the key switch K' at the upper left corner is operated. The same goes for the other key switches, and the timing pulse is applied to the output terminals N ₁ to _{N 4} .
By generating synchronized pulses from _t1 to _t4 , the voice recognition output is input to the information processing device in the same way as when operating a key switch on a keyboard.

As is clear from the above description, the present invention allows the voice recognition output to be input in the same way as when inputting by keyboard operation, making it possible to increase the functionality of the information processing device, and outputting the output to the input line of the I/O port. Since it is introduced in a pulse form that is synchronized with the timing pulse of the line, there is no increase in the burden on the I/O ports, and its practicality is extremely high.
