Abstract

PURPOSE:To make a portable telephone set small in size and light in weight by providing a voice recognition means able to identify at least numerals of 0-9 of human voice signals inputted through a microphone and a voice output means outputting the identified numerals as sound. CONSTITUTION:When numerals of 0-9 are uttered onto a microphone 27, the voice is identified by a voice recognition LSI 26, a character code is decided and the result is stored into a RAM 18 with an address. A CPU 2 reads the address and the character code from the RAM 18, extracts a relevant voice data from a ROM 4 and outputted as sound from an ear piece 16 via an AF processing section 17 and an ear piece amplifier 15. If the sound output is in error, a talker depresses a return key (upward or downward triangle mark) are tries to re-input of one preceding numeral digit.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a human voice recognition voice confirmation mobile phone, and more specifically, the present invention relates to a human voice recognition voice confirmation mobile phone. The present invention relates to a human voice recognition voice confirmation mobile phone that can make a call to the other party corresponding to the numerical value.

[Prior Art J An example of a conventional mobile phone is shown in an IS diagram and FIG. 6.

When making a call to the other party using the 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 using the key switch 24 and displays it on the LCD 22.

If the displayed phone number is correct, press send key 5Nf)
Press.

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 1°, 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.

Furthermore, although an LCD is provided to confirm the entered telephone number, etc., this LCD is a factor that prevents mobile phones from becoming thinner.

Therefore, an object of the present invention is to eliminate the need for a large number of buttons by making it possible to operate using human voice, and to
To provide a human voice recognition voice confirmation mobile phone that eliminates the need for an LCD by enabling the confirmation by voice.

[Means for Solving the Problems] The human voice recognition voice confirmation mobile phone 1 of the present invention has a microphone 2.
voice recognition means 26 for identifying at least numerical values from O to 9 with respect to the human voice signal inputted through voice signal 7; voice output means 2 for voice outputting the identified numerical values; Calling means 2 for calling the other party
The structural feature is that it is equipped with the following.

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.

[Operation] In the human voice recognition voice confirmation mobile phone of the present invention, the voice recognition means identifies at least numerical values from 0 to 9.

Further, when a numerical value is recognized, the voice output means outputs the numerical value as voice.

Therefore, by speaking the numerical values corresponding to the telephone number in sequence, it is possible to check whether the numbers have been recognized correctly or not.

After this voice output, if an operation to make a call is performed or an operation to stop the 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 0 to 9, or if a combination of numbers from 0 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.

Furthermore, since confirmation can be made by voice, there is no need for a character display means such as an LCD, and the mobile phone can be made thinner.

[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 voice confirmation 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. However, C
Since the PU2, ROM4, etc. perform the operations according to the present invention, they are not completely the same as the conventional ones. Note that new components that have no counterpart in the conventional device are a touch switch 23°, 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 voice confirmation mobile phone 1 small and lightweight, the voice learning module LM is not built-in but is connected externally.

FIG. 3 shows the appearance of the human voice recognition voice confirmation mobile phone 1, in which (a) is a front view, (b) is a side view, (C) is a rear view, and (d) is a top view.

By providing the button key 24 on the top surface and not providing an LCD, the conventional mobile phone 51 (sixth
It is smaller, lighter, and thinner than the previous model (see figure).

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

First of all, (before the caller presses the command button 24, no voice reception is accepted. This is to prevent erroneous calls.

When the function key FCN of the button key 24 is pressed, the CPU 2
begins to accept human voices input from the microphone 27 (SL, 82).

Therefore, a numerical value from O to 9 is sounded and input into the microphone 27 (S8).

The CPU 2 has a microphone amplifier 28. The AF processing unit 10 and the voice recognition LSI 26 are activated, and the voice recognition LSI 26 identifies the human voice input from the microphone 27 (S4).

Then, the numerical value identified by the voice recognition LSI 26 is received, a character code is determined, and an address is attached and stored in the RAM 18 (S5).

The CPU 2 reads the address and character code from the RAM 18, takes out the corresponding audio data from the ROM 4, and outputs the audio from the earpiece 16 via the AF processing section 17 and the earpiece amplifier 15 (S6).

S7. Repeats the above operations 83 to S6. S8): Input the telephone number of the other party in sequence using a human voice.

When you finish inputting and release the function key FCN (S8), the CPU
2, check whether the number of digits entered is 3 digits (S9); if it is not 3 digits, the operator presses the send key SND.
Wait until you press .

When the operator confirms by voice output that the phone number has been correctly recognized (S10), press the send key SND (
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 voice output is incorrect, the caller presses the return button (S14).

Then, the CPU 2 returns the address by one digit and stores the character code of "space" in that address (S15
). This allows re-input to the previous position.

Now, in step S9 above, if the number of digits input by the time the function button FCN is released is 3, then C
The PU 2 searches the abbreviated number list stored in advance in the RAM 18, extracts the telephone number corresponding to the input three-digit number, and outputs it as a voice. This makes it possible to use the abbreviated number function.

The voice recognition LSI 26 can identify human voices such as "power supply voltage", "field strength", and "home roam" in addition to the numerical values 0 to 9, and when the voice input of "power supply voltage" is made, the CP
U2 outputs the battery voltage as an audio signal. Also, "electric field strength"
When the voice input is made, the CPU 2 outputs the received electric field strength as voice. Furthermore, when a voice input of "home roam" is made, the CPU 2 recognizes it as an instruction of home/roam.

Note that it is also possible to store a long message in the RAM 18 and then send it.

[Effects of the Invention] According to the human voice recognition voice confirmation mobile phone of the present invention, at least a telephone number can be entered using a human voice, it can be confirmed by voice, and a call can be made automatically to that telephone number. Therefore, there is no need for any buttons at all, or only a few stages are sufficient, making it possible to make mobile phones smaller and lighter. Furthermore, even when adding a large number of functions, there is no need to add additional buttons. Furthermore, since a character display means such as an LCD is not required, the mobile phone can be made thinner.
