Abstract

PURPOSE:To prevent malfunction by providing a main input means inputting a data by voice recognition and an auxiliary input means comprising a key/ button or the like so as to use an input data of the main input means thereby controlling the inhibition/permission of data input to the auxiliary input means. CONSTITUTION:For example, a voice of 'on' is inputted to a microphone 1, then a voice recognition circuit 2 outputs an input enable signal onto a line 3. When the signal is detected by an input enable signal identification circuit 8, since a terminal Q of a flip-flop 10 goes to an H level, a sign signal on a line 7 is fed to an OR gate 12. That is, the input from a key/button board 5 is attained. With a voice of 'off' given, the identification circuit 9 receives an 'input disable' signal and the terminal Q of the flip-flop 10 goes to an L level. As a result, since the sign signal on the line 7 is not supplied to the OR gate 12, the input from the key/button board 5 is inhibited.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an input device, and more particularly to an electronic circuit for inputting data by voice.

[Conventional technology]

For example, most conventional telephones have dials or key buttons as data input means, and some telephones also have voice recognition input means in addition to the above input means6. In the latter telephone, two input means, voice and data, were not given input priority and were treated equally. The above-mentioned situation was also the same for data input means in conventional mobile @ radio equipment6.
[Problems to be Solved by the Invention] Due to advances in technology, mobile radio devices are becoming smaller and lighter in weight, and are increasingly being used while being stored in briefcases or pockets. In such usage conditions, devices with mechanical input means such as key buttons or electrical input means such as touch sensors may be used in a storage space in which the device is stored or other objects stored in the same storage space. If the input means of the device comes into contact with the device, malfunctions may occur. For example, mobile radios have the problem of erroneous transmissions.

Furthermore, as a means of downsizing the device, even the mechanical input means itself has been downsized, making it difficult to perform input operations. As a countermeasure.

Input means based on voice recognition may be used, but since the voice recognition rate is not 100%, mechanical means such as those described above are also used.

If you use such a device while it is stored in a storage object,
As mentioned above, there was a problem of erroneous operation.

SUMMARY OF THE INVENTION An object of the present invention is to provide an input means that is easy to handle and does not malfunction, without hindering the miniaturization of a device body equipped with an input device.

[Means for solving problems]

[1] The main input means is a means for inputting data by voice recognition, and a means for inputting data by a broad contact operation such as a mechanical input means such as a key button or an electrical input means such as a touch sensor. This is achieved by using the auxiliary input means as an auxiliary input means, and providing means for controlling prohibition and permission of data input by the auxiliary input means based on control data inputted by the main input means.

[Effect]

9 Permit or prohibit data input by the auxiliary input means based on the data inputted from the main input means, such as "on" or "off." 6 Carrying the main body of the device equipped with the input device according to the present invention in a briefcase. , before storing the device in a storage object such as a pocket and using it, inputting the "off" data from the main input means inhibits input from the auxiliary input means. Thereby,
Even if the auxiliary input means comes into contact with another object within the stored item.

Since that input is prohibited, there will be no malfunction.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. Voice input to a microphone 1 is converted into an electrical signal and input to a voice recognition circuit 2. Its speech recognition circuit recognizes input speech.

A first code signal corresponding to the input voice is outputted to the control port 14 from tjA3. On the other hand, when a certain key on the keyboard button board 5 is pressed, the key position signal is input to the decoding circuit 6. The Dude circuit converts the position signal into a corresponding second code signal and outputs it to the control circuit 4 on the line 7. In the control circuit 4, the input permission signal identification circuit 8 indicates the input permission signal on 1lia. It is detected that the `` signal is cursed, and the R-S flip-flop 10 is set by the 11'' level signal, and the Q output signal of the flip-flop is set to the ``1'' level. In addition, the input prohibition signal identification circuit 9 detects the appearance of the input prohibition j signal on the line z3, and detects the R-S by the reset signal of the "1" level.
The flip-flop 10 is reset and its Q output signal is set to the "0" level.

The logical product of the Q output signal and the second code signal on line 7 is A
N I) is taken by gate 11, and its output signal is further logically summed with the first code signal on line 3 by OR gate 12. Note that when there is no input to the microphone 1, the level on the line 3 is the "0" level, and when there is no input on the keyboard board 5, the level on the line 7 is the "0" level. The output signal of the OR gate 12 is supplied via line 13 to the code processing circuit 14 and other circuits.

In the embodiment of FIG. 1, for example, when the voice "on" is input into the microphone 1, the voice recognition circuit 2 outputs a corresponding code signal, ie, an "input permission" signal on line 3. This signal is detected by the input permission signal identification circuit 8, and the Q output signal of the flip-flop 10 becomes the "1" level, so the code signal on the line 7 is supplied to the OR gate 12. In addition to the input, input from the keyboard board 5 becomes possible.Next, when a voice such as "r off" is input into the microphone 1, the voice recognition circuit 2 generates a corresponding code signal, that is, "input prohibited". ” signal on line 3. This signal is detected by the input prohibition signal identification circuit 9, and the Q output signal of the flip-flop 10 is at the "0" level, so that the code signal on the line 7 is not supplied to the OR gate 12.

That is, input from the keyboard board 5 is prohibited.

As described above, the input from the microphone 1 is used as the main input means, and the input from the keyboard board 5 is used as the auxiliary input means. If there is a possibility that an inadvertent input may be made from the auxiliary input means, malfunctions can be prevented by prohibiting human input from the auxiliary input means using the main input means in advance.

Another embodiment of the present invention will be described with reference to FIG.

In this embodiment, the output signal of the first human power prohibition signal identification circuit 9 is input to the OR gate 16. The reset signal generation circuit 18 outputs a "1" level reset signal to the OR gate 16 when the power supply 17 is turned on. The second human power prohibition signal identification circuit 19 detects the "input prohibition" signal on the line 7 and outputs a reset signal of "]" level to the gate 16 . The timer 8 is reset by the [1j level reset request] generated when the human power permission signal/identification circuit 8 detects the "man power permission" signal. Thereafter, the timer 8 counts the clock signal from the clock source 21.

When a predetermined number of counts is completed, a reset signal of "1" level is output to the gate 16. The Q output signal of the flip-flop 10 is brought to the "0" level by one of the four types of reset signals input to the gate 16.

In the embodiment shown in FIG. 2, as in the embodiment shown in FIG. 1, manual input from the microphone is the main input means, and input from the keyboard 5 is the auxiliary input means. According to this embodiment, since input from the auxiliary input means is automatically prohibited when the power source 17 is turned on, there is an effect that the trouble of prohibiting input from the auxiliary input means by the main input means can be saved. . Further, according to this embodiment, there is an effect that input from the auxiliary input means can be prohibited by either the main input means or the auxiliary input means. Further, according to this embodiment, the operation of the timer 20 prohibits manual input from the auxiliary input means after a certain period of time after the input from the auxiliary input means becomes possible due to the input from the main input means. 1y) The input means has the effect of saving the effort of prohibiting input from the input means.
