DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic desk calculator with a voice input function which performs calculations by voice input. In detail, operations such as addition, subtraction, multiplication, and division are also performed based on the specified currency rate by voice input in addition to key input, so that the conversion process in a specific currency can be simplified. is there.

[0002]

2. Description of the Related Art Overseas travel booms are unaware of the decline even in a chaotic economy. There are many shopping opportunities overseas. Shopping is done in local currency, so if you do not know the total price in local currency and the price converted to yen each time you shop, you can see how much local currency remains at hand, in yen conversion You can't know exactly how much you've shopped. Since it is uneasy to leave the total amount and the balance in mental arithmetic, an electronic desk calculator (calculator) is generally used.

[0003]

[Problems to be Solved by the Invention] By the way, when shopping at the site, it is understood that Japanese tourists are shopping by hitting the key of the calculator and thinking about the total price while shopping. This can lead to creating an environment where Japanese people can easily be targeted.

[0004] Even if a calculator is used, it is difficult to understand, or if conversion to local currency or yen can be performed quickly and without hitting a key, the local currency can be safely relied on without being disturbed by local people. You can know exactly the total amount, the balance, and the total amount and balance when converted into yen.

In view of the above, the present invention has been made to solve such a conventional problem. In this invention, a currency unit indicating a calculation reference and a monetary amount can be inputted by voice. The present invention proposes an electronic desk calculator with a voice input function capable of displaying the results of calculation processing as described above.

[0006]

In order to solve the above-mentioned problems, an electronic desk-top computer with a voice recognition function according to the first aspect of the present invention analyzes a headset and a voice input from the headset. Voice recognition means for identifying numbers, arithmetic symbols, and the like, a voice code section for outputting voice codes corresponding to the numbers, symbols, and the like, and an output recognized by the voice recognition section matched the voice code. When the output is supplied, the operation unit includes a currency storage unit for storing a currency rate, a storage unit for storing a calculation result, and a display unit for displaying numbers and the like, and the type of currency input from the headset. And the conversion rate are stored in the currency storage unit, and an operation according to a voice input instruction from the headset is executed based on the selected currency, and the result is Characterized in that adapted to be displayed on the radical 113.

According to the present invention, the same processing as a key operation is performed by voice input. In other words, from the power on / off, the type of currency, the type of currency to be converted, and the conversion rate at that time are all input by voice. The voice input is recognized, converted into a specific code corresponding to a number, a symbol, and a currency, and sent to the arithmetic unit to perform a normal arithmetic process on the calculator.

For example, when the power is turned on, a currency to be used as a reference for calculation is specified, and a voice is input as “Ichi Tasuni”, the voice is recognized and converted into a code (corresponding to a key signal of a calculator). By performing the conversion and leading the converted code to the calculation unit, an addition process of “1 + 2” is performed, and thereafter, the currency to be converted and the conversion rate at that time are designated.

A conversion process based on the designation of the currency and the conversion rate is executed, and the calculation result is stored in a storage unit (memory), and the calculation result is displayed on a display unit (LCD, etc.). For example, when dollar is designated as the first entered local currency, the total in the local currency is three dollars, and the value of this total is displayed.

Then, in the next stage, the yen is designated as the currency to be converted, and the conversion rate at that time is, for example, 11 yen.
When 0 yen is input by voice, the price in yen at that time is displayed as 330 yen. If the currency to be converted and the conversion rate are not specified, the calculation result ($ 3) of the currency ($) initially input by voice is saved and displayed as it is.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of an electronic desk calculator with a voice input function according to the present invention will be described in detail with reference to the drawings. Referring to FIG. 2, FIG. 2 shows the appearance of the electronic desk calculator 10 according to the present invention, and a key operation unit 14 composed of a plurality of keys is provided at a substantially central portion of the flat computer body 12. A display unit 16 such as a liquid crystal display (LCD) is provided at the upper center. Further, in this example, a built-in microphone 18 for a headset used for voice input is housed at the lower end of the key operation unit 14. At the upper end of the main body opposite to the built-in microphone 18, a confirmation sound generating element 19 using a piezoelectric element or the like emitted when confirming a voice input described later is housed.

FIG. 1 is a system diagram of a main portion showing an embodiment of an arithmetic processing section 20 of an electronic desk calculator 10 with a voice input function according to the present invention. In the figure, a key signal input from a key operation unit 14 is subjected to calculations such as addition, subtraction, multiplication and division by a CPU 22 and a calculation unit 24, and the result is stored in a calculation data storage unit 26 formed of a memory such as a RAM. Is done. Then, the calculation result is displayed on the display unit 16.

In the present invention, in addition to these components, means for realizing the same processing as key input by voice input is added. In other words, the arithmetic processing unit 20 stores information necessary for calculation as a voice code in the voice data storage unit 3.
0 is provided.

Further, the voice input from the built-in microphone 18 is supplied to voice recognition means 32, where the input voice is analyzed and collation using the voice data from the voice data storage unit 30 is performed. The voice data obtained as a result of the collation is supplied to the calculation unit 24 in the same manner as the key signal, and the four arithmetic operations are performed.
The numbers and calculation results input by voice are displayed on the display unit 16.

[0015] Of the voice input from the built-in microphone 18, the voice input particularly concerning the type of currency and the conversion rate (exchange rate) is once subjected to recognition processing by the voice recognition means 32, and then is subjected to a currency conversion memory (for example, , RAM) 34. When there is voice data corresponding to the input voice as a result of the voice input, the confirmation sound generating means 36 is driven, and a confirmation sound of the voice input is emitted as in the case of the key input. As the confirmation sound generating means 36, a piezoelectric element or the like can be used.

The information necessary for the calculation stored in the voice data storage unit 30 includes at least "tas (add)", "hike (draw)", "kake (multiply)", and "wal (divide)". And the information required for the four arithmetic operations. There are also voice inputs “On” and “Off” for turning the calculator on and off, dollars, pounds,
Currency unit (currency type) such as mark, won, yuan, yen,
Further, conversion rate information and the like are stored. Here, the four arithmetic operations are "tas", "hiku", "kakeru",
It should be specified in "Wal" and the currency is "Dollar""En"
And the like are directly specified by voice, and the conversion rate is specified as “rate xxx”.

Next, an embodiment of the arithmetic processing by voice input will be described with reference to FIG. First, the built-in microphone 18
Input "On" and voice input using
0). The voice input is recognized, and when it is recognized that the power is turned on, the power is turned on and a confirmation sound, for example, "Pee" indicating that the voice input is recognized is emitted (step 42).

Next, a voice input for designating a unit currency required for the arithmetic processing is performed (step 44). This currency input is stored in the storage unit as the operation unit currency, and the currency input causes the arithmetic processing to be performed according to the input currency (step 46). This is because, for example, the way of calculation such as the four arithmetic calculations changes between dollar currency and yen currency. In the following example, a case where “dollar” is selected as the calculation currency will be described.

When a predetermined time elapses after the power is turned on and a timeout occurs, a predetermined currency is used as a calculation unit (steps 48 and 50). The default currency is preferably associated with the owner, but for example, in Japan, it is a yen currency. When the calculation reference is specified, the system enters a state of waiting for input of a numerical value or the like.

When there is a voice input of a specific calculation value, the content is analyzed and the analysis result is passed to the calculation unit 24 to perform a calculation process (step 54). This voice input is, for example, a voice instruction such as “Ichi Tasuni” as described above. When the confirmation sound is heard when the voice input is recognized, the calculation unit 24 performs the calculation of “1 + 2 = 3 (dollar)” at that time. The input numbers (1, 1) are displayed on the display unit 16.
2) (dollar) and the numerical result 3 (dollar) of the calculation result are sequentially displayed. This is the same display mode as a key input with a normal calculator.

In spite of the input of the currency used as the reference for calculation, there is no input of the calculation value after a lapse of a predetermined time thereafter, and when a timeout occurs, the power supply is automatically turned off as described later. (Step 6
8).

Next, a standby state is entered for voice input of the conversion currency and the conversion rate (step 58). For example, if you want to convert dollars to yen, use "en"
(Yen), then "rate hakuju"
(Rate 110) is input by voice (step 58). The contents of the conversion currency and the conversion rate are stored in the currency conversion memory 34, respectively, and are also supplied to the calculation unit 24 to perform the following conversion processing (step 60). A confirmation sound is emitted at the same time. 3 × 110 = 330 (yen) The conversion processing result (330 yen) is displayed on the display unit 16 (step 64). At this time, if the conversion currency symbol (yen mark \) is also displayed at the same time, it is possible to reliably recognize that the price is in Japanese yen.

When the voice input of the conversion currency or conversion rate has not been made for a predetermined period of time and timed out (step 6).
2) The currency input in step 44, that is, the currency used as a reference for calculation is displayed on the display unit 16 (steps 62 and 64). In this example, the result calculated in dollars ($ 3) is displayed as it is.

In this way, the display can be performed in the local currency when the local currency can be used in time. This display has the same contents as those displayed in step 54.

Therefore, in step 54, the calculation result in the local currency is displayed, and in step 64, the converted result is displayed. Thus, the price in the local currency and the price in the case of switching to another currency are calculated. You can see both.

When the final calculation result is displayed, the process waits for an input instruction to perform the same calculation process or to turn off the power (steps 66 and 52).
When the voice input is made, the power supply is automatically turned off, a confirmation sound is output at that time, and a series of processes is completed (steps 66 and 68).

In the above-described embodiment, the numerical value of the calculation result is only displayed on the display unit 16 and is not output as a voice, but the calculation processing unit 20 shown in FIG. If an output unit (such as a speaker or a piezoelectric element) is added, it is also possible to notify the operation result and the like by voice. In this case, the type of currency can also be output as audio. For example, if the numerical value and currency are output simultaneously by voice, such as "$ 3" or "330 en",
The user can definitely grasp the shopping price.

In the above-described embodiment, "dollar" has been described as a currency serving as a reference for calculation, and "yen" has been described as a currency to be converted. However, these are merely examples, and other currencies may be designated. It goes without saying that you can do it. For example, "Pound" or "Yuan"
Can be designated as "yen" or "dollar" as a currency to be converted. Therefore, it is only necessary to store the world's leading currencies in the currency conversion memory 34, and to prepare the calculation unit 24 with calculation software capable of calculating such currencies.

In addition, the budget is input in Japanese yen in advance, and the balance is saved while shopping in the local currency.
It can also be configured to display. In this case,
For example, as a voice input, “yosan sen sang bia kuen” (budget 1,300 yen) is input first, and the value is stored in the storage unit 26 or the like. Then, every time shopping is performed, the user inputs voice as “Nidol” ($ 2) and “Godol” ($ 5).

In this case, the calculation unit 26 sets the conversion rate to 1
When the dollar is 110 yen, the display unit 16 displays that the remaining balance of 1,300 yen−2 dollars × 110 yen = 1,180 yen when shopping for 2 dollars is obtained. And
Further, by shopping for $ 5, the remaining balance at that time 1,180 yen-$ 5 x 110 yen = 630 yen is displayed on the display unit 16. The balance can be output as audio. Various display modes can be realized by incorporating such calculation software.

[0031]

As described above, according to the present invention, the same processing as a key operation can be performed by voice input. In other words, from the power on / off, the type of currency, the type of currency to be converted, and the conversion rate at that time are all input by voice. This voice input is recognized, converted to a specific code corresponding to a number, a symbol, and a currency, and sent to a calculation unit, and a normal calculation process is performed on a calculator. Therefore, calculations can be easily performed without operating keys. The calculation result can be displayed in the local currency or another currency or output in voice, so that there is no calculation error or misunderstanding of the currency. Therefore, local shopping can be enjoyed with ease.
