Abstract

PURPOSE:To dial a telephone number automatically according to a human voice by providing a voice recognition means able to identify numerals from 0 to 9, a numeral display means displaying an identified numeral and a dial means dialing a telephone number corresponding to the numeral. CONSTITUTION:An instruction key being a push key 24 is depressed, then a CPU 2 receives a human voice inputted from a microphone 27. Then numerals from 0 to 9 are sounded and entered to the microphone 27. The CPU 2 activates a voice recognition LSI 26 to identify the entered human voice. Then the numerals identified by the LSI 26 are received, a character code is decided and stored in a RAM 18 while an address is provided. Then the address and the character code are sent to an LCD 22 and displayed on a relevant display area. The operation above is repeated and a destination telephone number is inputted in voice sequentially. When a talker observes a display of the telephone number of the LCD 22 and confirms it to be correct, then the talker depresses a send key being a touch switch 23. Thus, the CPU 2 uses a numeral data stored in the RAm 18 as the destination telephone number to make dialing.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a human voice recognition mobile phone, and more specifically to a human voice recognition mobile phone that allows you to call the other party by inputting numerical values by voice. Regarding.

[Conventional technology] An example of a conventional mobile phone is shown in FIGS. 5 and 6.

When making a call to the other party using this mobile phone 51, the user presses the numerical key of the key switch 24 and inputs the telephone number of the other party.

The CPU 2 reads the telephone number input from the key switch 24 and displays it on the LCD 22.

If the displayed phone number is correct, press the send key SND.

When the send key SND is pressed, the CPU 2 sends the send synthesizer 8. It controls the DTMF generator 9 and the AF processing section 10, and transmits a connection request signal to the base station via the mobile phone transmission section 13 and the antenna cooperation section 6 on a control channel.

To make a call as described above, a total of 11 buttons are required, including numerical keys from O to 9 and a send key SND. However, in reality, additional buttons are provided for other additional functions, and usually one
There are from 5 to 21 buttons.

[Problems to be Solved by the Invention] As mentioned above, conventional mobile phones are usually provided with 15 to 21 buttons, but the size and spacing of the buttons should be made smaller in relation to the size of the fingers. Since there is a limit to the size of the button, it is not possible to reduce the size of the part where the button is installed, which is a bottleneck in making mobile phones smaller and lighter.

Furthermore, with the spread of mobile phones, there is a demand for multi-functions, but increasing the number of buttons for this purpose causes the mobile phone to become larger, making it inconvenient to carry.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a human voice recognition mobile phone that can be operated using human voice, thereby eliminating the need for a large number of button keys.

[Means for Solving Problem ff1] The human voice recognition mobile phone 1 of the present invention includes a voice recognition means 26 capable of identifying at least numerical values from O to 9 in a human voice signal inputted through a microphone 27; The system is characterized in that it includes a numerical display means 22 for displaying the identified numerical values in order, and a calling means 2 for making a call to the destination corresponding to the displayed numerical values.

Note that the reference numerals of each of the above-mentioned constituent elements are the reference numerals of the main corresponding constituent elements in the embodiments.

[Function] In the human voice recognition mobile phone of the present invention, the voice recognition means identifies at least the numerical values from 0 to 9, so that the numerical values from 0 to 9 can be input using the human voice.

Therefore, by uttering the numerical values corresponding to the telephone number one after the other, the numerical display means displays them in order.

After this display, if an operation is performed to make a call or an operation to stop making a call is not performed, the calling means calls the other party.

Therefore, at least 10 buttons can be omitted, and the mobile phone can be made smaller and lighter by that much.

In addition, if the discrimination ability of the voice recognition means is improved to be able to identify human voices other than the numbers O to 9, or if a combination of numbers from O to 9 is made to correspond to one command,
All or most of the functional buttons can be omitted. Therefore, advanced functions can be added without increasing the size of the mobile phone.

[Example] Hereinafter, the present invention will be described in more detail based on the example shown in the drawings. Note that this invention is not limited to this.

FIG. 1 is a block diagram showing a human voice recognition mobile phone 1 according to an embodiment of the present invention.

Components corresponding to those of the conventional mobile phone 51 shown in FIG. 5 are given the same reference numerals. A completely new component that has no counterpart in the conventional device is the touch switch 23. They are a voice recognition LSI 26 and an external interface 25.

The voice recognition LSI 26 has a basic configuration as shown in FIG. 2, and performs voice recognition by voiceprint recognition.

In order to make the human voice recognition mobile phone 1 smaller and lighter, the voice learning module LM is not built-in but is connected externally.

FIG. 3 shows the external appearance of the human voice recognition mobile phone 1. Only two buttons 24 are provided, and the LCD 2
2 has a larger area than the conventional one, a touch panel is installed on the front surface thereof, and a touch switch 23 is formed in an area near the key figure displayed on the LCD 22.

Next, FIG. 4 is a flowchart showing the operation of the human voice recognition mobile phone 1 to make a call. The operation of making a call will be explained below according to the flowchart.

First, until the caller presses the command button 24, the caller's voice is not answered. This is to prevent erroneous calls.

When the command key of the button key 24 is pressed, the CPU 2 starts accepting human voices input from the microphone 27 (S
L, S2). Then, the user pronounces and inputs numerical values from 0 to 9 into the microphone 27 (s3).

The CPU 2 has a microphone amplifier 28. The AF processing unit 10 and the voice recognition aLsI 26 are activated, and the voice recognition LSI 26 identifies the human voice input from the microphone 27 (S4
). Then, it receives the numerical value identified by the voice recognition LSI 26, determines the character code, attaches an address, and stores it in RAM1.

Also, send the address and character code to the LCD 22,
Display it in the corresponding display area (S6).

S7. Repeats the above operations 33 to S7. S8): Input the telephone number of the other party in sequence using a human voice.

When you finish inputting and release the command key (S8), the CPU 2

), if it is not 3 digits, the key shapes of the send key and return key will be displayed on the LCD 22, and the touch switch 23 will be displayed in the corresponding area.
form.

This state is shown in FIG. However, the voice recognition LSI 26 is also capable of recognizing "space", and "space" is also displayed along with the numerical values 0 to 9.

This "space" is ignored when making a call.

When the caller looks at the telephone number displayed on the LCD 22 and confirms that it is correct (S10), he or she presses the send key of the touch switch 23 (Sll).

As a result, the CPU 2 performs a call operation using the numerical data stored in the RAM 18 as the telephone number of the other party (
S12).

However, if the display on the LCD 22 is incorrect, the caller presses the return key on the touch switch 23 (S14).
.

Then, the CPU 2 returns the address by one digit and sends the character code "Space" to the LCD 22 corresponding to that address (S15). This makes it possible to re-enter the previous digit and also erase the display of that digit.

Now, in step S9 above, if the number of digits input by the time the command button 24 is released is 3 digits, the CP
U2 searches the abbreviated number list stored in advance in the RAM 18, retrieves the telephone number corresponding to the input three-digit number, and displays it on the LCD 22. This makes it possible to use the abbreviated number function.

The voice recognition LSI 26 has a "list" in addition to the numbers O to 9.
and “scroll” human voices are discernible, and “list”
When the voice input is performed, the CPU 2 displays a part of the abbreviated number list stored in the RAM 18 on the LCD 22.

Then, by inputting the human voice "scroll", the part of the abbreviated number list that was not displayed on the LCD 22 is scrolled and displayed. This allows you to easily check the abbreviated number of the desired telephone number.

Furthermore, if the voice recognition LSI 26 enables voice recognition of English characters, kana characters, etc., it will also be possible to read out telephone numbers using abbreviations. It is also possible to send messages.

Note that if you press the mode key of the key switch 24, the CPU
2 displays numerical values from O to 9, a book, and the sign # on the LCD 22, and forms a touch switch 23 in the corresponding area. In this touch switch mode, you can enter a phone number by touch operation, as in the past.

[Effects of the Invention] According to the human voice recognition mobile phone of the present invention, at least a telephone number can be input using a human voice, and a call can be made automatically to that telephone number. Therefore, there is no need for a button at all, or it is sufficient to provide only a few buttons, making it possible to make the mobile phone smaller and lighter. Furthermore, even when adding a large number of functions, there is no need to add additional buttons.
