Description

DETAILED DESCRIPTION OF THE INVENTION (Technical field to which the invention pertains) The present invention relates to a portable wireless device, and in particular,
This invention relates to a portable wireless device that does not have a keyboard for calling the number of the other party.

(Prior art and its problems) The present invention relates to a general portable radio device, but
In the following description, a portable radiotelephone device will be described for ease of explanation. The difference between portable radio telephone devices and other general radio devices is that the number entered using the keyboard is a public telephone number or the selective calling number of the other party's radio, so for the purpose of explanation, we will use general Never lose your sexuality.

FIG. 5 is a block diagram showing an example of the circuit configuration of a conventional portable radio telephone device, and FIG. 6 is a flowchart of a calling operation when calling the other party with the conventional device. Fifth
6, the operations during a call are as follows.

First, in the case of transmission, the audio signal picked up from the microphone 31 is sent to the modulation unit 33 via the preprocessing unit 32.
After being modulated using a modulation method suitable for the wireless transmission path, the signal is converted to a radio frequency by the wireless transmitting/receiving section 34, amplified to a predetermined power, and then sent out into space through the antenna 39. On the other hand, the received wave from the communication partner excites a high frequency voltage in the antenna 39 by electromagnetic waves propagating in space.
This high-frequency voltage is frequency-converted and amplified by the wireless transmitting/receiving section 34, from which only the desired signal is extracted, and the demodulating section 34 extracts only the desired signal.
After being demodulated in step 5 and subjected to signal processing in post-processing section 36,
The signal becomes an audible signal and is output as sound from the speaker 37.

The control section 38 performs a man-machine interface using a display section 310 and a keyboard 311, and also controls the wireless transmitting/receiving section 34. Therefore, manual input such as telephone numbers is performed via this keyboard 311.

The calling operation in this case is performed according to the flowchart shown in FIG. In FIG. 6, the caller inputs the telephone number or selective calling number of the other party using the keyboard 311 of the device (step 61).

The number input from the keyboard 311 is converted into a transmission code by the control unit 38 (step 62). This converted code is sent to the wireless transmitting/receiving section 34 via the modulating section 33.

As described above, a portable wireless device that is wirelessly connected to a telephone line or the like is provided with a keyboard 311 for inputting the telephone number of the other party and a display section 310 for displaying the keyboard.

The keyboard 311 for inputting a telephone number has keys for numbers 0 to 9 and other symbols such as * and #, and its dimensions and arrangement require a certain amount of space from the viewpoint of operability. For this reason, the external dimensions and design of the portable wireless device itself are limited by the keyboard used, and as the device becomes smaller, its volume occupies an extremely large proportion of the entire device, which poses a major problem in miniaturizing the device. It becomes.

(Object of the Invention) The object of the present invention is to provide a portable wireless device that eliminates many of the limitations of such a keyboard, has a smaller size, expands the degree of freedom in design, improves operability, and reduces costs. The goal is to provide equipment.

(Structure and operation of the invention) The portable radio device of the present invention introduces voice recognition technology, and inputs the calling number by voice input from a microphone as an alternative to the conventional keyboard in which the number of the other party is entered manually. The main feature is that it is equipped with a voice recognition unit that converts the predetermined calling number into a telephone number signal corresponding to the calling number, and a voice response unit that obtains a response from the device to the voice control. It is.

The present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a block diagram of a circuit showing one embodiment of the present invention, and FIG. 2 is a flowchart of its calling operation.

In FIG. 1, the voice of the telephone number or selective calling number of the communication partner is converted into a voice signal by a microphone 11, converted into a telephone number signal by a voice recognition unit 112, converted into a transmission code by a control unit 18, and modulated. The information is input to section 13. Here, the carrier wave is modulated and sent out into space via the wireless transmitting/receiving section 14. After receiving a response from the other party, the call signal is processed by a preprocessing section 12.degree. modulation section 13. The signal is transmitted into space via the wireless transmitter/receiver 14 and antenna 19. On the other hand, radio waves received from the communication partner are transmitted to the wireless transmitting/receiving unit 1 via the antenna 19.
4. The signal is converted into audio via the demodulator 15, post-processor 16, and speaker 17.

Reference numeral 111 denotes a switch (SW) for switching between performing call operations and other controls by voice and making a call, and most of the operations using the conventional keyboard 311 are performed by a combination of the voice recognition unit 112 and the control unit 18. . switch 11
1 may be extremely simple, such as using an automatic return type switch that is pressed only during call origination or control to connect to the voice recognition side. Furthermore, if a specific rule is set in the voice recognition unit 112, the switch 111 can be turned off. For example, when uttering a control signal, always utter ``start'', and when it is finished, utter ``end''. Say aloud.Also, set this time to 20
Rules such as doing it within seconds. “Start J+ r03-59
1-6111J, r end.''

In other words, when you say the word "start", 5WII
When I is moved toward the voice recognition section 112 side and the word "end" is uttered, this corresponds to the opposite movement toward the preprocessing section 12 side. Further, the display unit 110 is a monitor for checking the number of the calling party, etc. Furthermore, a voice response section 113 is provided for causing the speaker 17 to respond to the display contents of the display section 110 with synthesized voice.

In FIG. 2, which shows the procedure for making a call using the configuration of the present invention shown in FIG. 1, the user of this device who wishes to make a call speaks the telephone number of the other party (step 21). In this case, it does not necessarily have to be a number. In other words, the voice recognition unit 112 may store a "password" or abbreviated number corresponding to the abbreviated dialing used in ordinary telephones. The voice recognition section 112 recognizes the voice signal from this voice input, and when it matches the stored password, converts it into a telephone number signal corresponding to the voice input, and the control section 18 converts it into a transmission code, which is then sent to the modulation section 13. It is transmitted via the wireless transmitting/receiving section 14.

Note that here, the modulation unit 13. Although the modulation and demodulation methods performed by the demodulator 15 are not particularly described, it is clear that the present invention can be realized using either analog modulation or demodulation or digital modulation and demodulation. When digital modulation and demodulation is used, it goes without saying that the pre-processing section 12 and the post-processing section 16 include an encoding section and a decoding section for analog audio signals and digital signals, respectively.

Now, in conventional wireless devices, when the power switch is turned on, the device is always in a standby or receiving state. Therefore,
If you want to make a call, hold the radio in your hand, enter the other party's number on the keyboard switch section, and finally press the "send" switch to enter the transmitting state.

In the wireless device according to the present invention, when the power switch is turned on, the wireless device is always in the standby or receiving state as described above, but at the same time, the voice recognition unit 112 is also in the standby state.

Therefore, S Will is switched to the voice recognition unit 112 side, and the voice signal from the microphone 11 is targeted for voice recognition. That is, a number or a control word pattern is memorized in advance, judgment is made by looking at the degree of similarity with the input signal, and the recognition result is sent to the control unit 18 as a predetermined number signal or control signal. Output.

FIG. 3 is a block diagram showing an outline of the circuit configuration of the speech recognition section 112, which is the main part of the present invention.

In the figure, reference numeral 61 denotes a voice recognition processing unit that analyzes a human voice signal and compares it with a reference pattern of word spirit stored in the reference pattern storage unit 60 in advance. Reference numeral 60 is a reference pattern storage unit, and the storage areas 63 to 66 are used to store information about the device.
"State Interval", "Transmission Mode".

Standard patterns of "calling number" and necessary double-digit "passwords" such as "control" and "end of transmission" for various operations are stored in advance. Reference numeral 62 denotes a recognition control section, in which the comparison judgment result from the voice input processing section 61 is manually converted into a predetermined number signal or control signal and output to the control section 18, as well as a switch 5W67 that sequentially switches various reference patterns.
and 68 are controlled.

The first switch 5W67 is switched once every time an audio signal is manually input and compared with the reference pattern in the reference pattern storage unit 60, and whether the audio signal input is a "status inquiry" of the radio or a control operation. “password” for doing
The switching is controlled by a control signal from the recognition control unit 62. The second switch 5W6B is
When the power is turned on, that is, in the initial state, "Transmission mode J" is selected.
It is connected to the reference pattern storage block 63 side, and as the operation progresses, the "calling number" reference pattern storage block 65. ``Control'' is sequentially switched to the ``end of transmission'' reference pattern storage block 66 by a control signal from the recognition control unit 62. ``After the transmission ends, it returns to the initial state.

FIG. 4 is a flowchart illustrating the voice call control operation of the voice recognition section of FIG. 3, and is flowchart 1 in a state where the 5W67 is connected to the control side. however,
Voice responses to voice operations are performed within each step or between each step, but are not shown.

In FIGS. 3 and 4, for example, when the input audio is in the "transmission mode" (step 41), a control signal is output to the modulation section 13 and the wireless transceiver section 14 to set the transmission mode, and the next "transmission mode" is output. 5 to the mode that recognizes the calling number.
W68 is switched (step 42). Next, when the calling number of the communication partner is inputted by voice using the required number of digits or the shortened password J, the "calling number" reference pattern 65 is checked and the number signal is converted into a number signal. When this process is completed, the 5W68 switches to the next reference pattern and waits for a "password" to put the radio into the transmitting state. Then, when the "Send ONJ" password is input (Step 4)
3) The recognition control section 62 outputs a control signal and a number signal for putting the radio into a transmitting state, and the control section 18 starts transmission. When a call is started after waiting for a response from the other party, the voice recognition unit 112 enters a mode in which it determines whether or not, for example, "end of transmission" is manually input as a "password" for ending the call (step 45). ). When the call ends and "end of transmission" is input, the voice recognition unit 112 determines this "password" and controls the radio to return to the standby state or the power switch state, which is the receiving state. A signal is sent to the control section 18. , the radio completes all transmissions according to the procedure determined by the radio system, and enters the standby or reception state.

In this series of processes, the speaker can control the radio by voice without manually operating the radio, and therefore becomes anxious if there is no response from the radio. Therefore, each time the voice recognition unit 112 finishes each mode, the voice response unit 113 makes a voice response through the speaker. For example, when a secret word for transmission is input, it may be ``send permission'' or ``please give me your number.'' At the same time, if the caller interrupts the task while inputting a password for some kind of control into the radio, and then attempts to resume the task, a password to know the state at the time of interruption, "Status Interval", is added. It is necessary to recognize and respond to this, and the control unit 18 has the function to do so using the voice response unit 1.
3, a voice response is made from the speaker 17.

(Effects of the Invention) As described above in detail, the following effects can be obtained by implementing the present invention.

(1) There are no restrictions on the design of the mobile radio telephone device, and a free shape, such as a rounded shape, can be adopted.

(2) The degree of freedom in structural design of the mobile radio telephone device increases.

(3) Therefore, it becomes possible to design an ergonomically suitable structure, and the shape improves operability, leading to increased popularity.
