Abstract

PURPOSE:To simply correct only a telephone number without an on-hook when erroneously dialing by once accumulating the dialed number by a caller, outputting it to the caller, recognizing and correcting it by the caller and thereafter outputting to a trunk line. CONSTITUTION:A caller presses only one column of a telephone number by a press type dial. Then, a dial signal is fed to a CPU 26 from a dial part 25. The CPU processes the dial signal and converts to the dial data, stores in a memory 27 and at the same time, calls up the voice data corresponding to the dial, feeds to a voice synthesizing part 28, converts to a voice signal and thereafter feeds to a receiver 23 through lines 18, 16 and an amplifier/filter 22. After the caller recognizes the voice output, if the number is erroneous, a correction key is pressed, subsequently, a correct number is dialed, and then, a correction signal is initially fed to the CPU 26, the CPU erases the dial data one column before and processes a next incoming dial signal.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a telephone set that allows for easy correction of incorrectly dialed telephone numbers.

BACKGROUND OF THE INVENTION Currently, telephones are widely used mainly in offices and households. Further, with the opening of telephones, telephones with various functions have been developed, mainly push-button telephones.

Among them, there are telephones that allow you to check the dialed phone number using an LCD display, and telephones that use voice dialing that uses voice recognition (you can check the dialed number using an LCD display).

There are recognition etc.

An example of the above-mentioned conventional telephone for confirmation using a liquid crystal display will be described below with reference to the drawings.

FIG. 2 shows a block diagram of a conventional telephone set that uses a liquid crystal display. In Figure 2, 1 is a telephone line, 2 to 4

The operation of the telephone configured as described above that uses a liquid crystal display for confirmation will be described below.

First, when a caller dials, a dial signal corresponding to the dialed telephone number is sent from the dial unit 10 to the CPU.
Sent to II. The CPU II converts the dial signal into a selection signal (dial pulse or multi-frequency code) corresponding to the telephone line 1, and at the same time displays the dialed telephone number on the liquid crystal.

Problems to be Solved by the Invention However, in the configuration described above, if a dial is made by mistake, it is difficult to dial on-hook once.
Reset the calling register of the central office exchange (RESET)
), you have to dial the phone number again from the beginning, which is very inconvenient.

In view of the above-mentioned problems, the present invention provides the following information:
To provide a telephone with which a telephone number can be easily corrected.

Means for Solving the Problems In order to solve the above problems, the telephone set of the present invention includes a storage circuit for temporarily storing dialed telephone numbers, and an output circuit for outputting the telephone number to the caller. The system is equipped with a correction circuit that allows the caller to correct the telephone number.

Effect of the Invention With the above-described configuration, the present invention temporarily stores the number dialed by the caller without immediately outputting it to the central office line, outputs it to the caller, and after the caller confirms and corrects the number. If you make a mistake in dialing, you can correct the incorrectly dialed phone number without going on-hook, making dialing operations more convenient than before. Excellent in that respect.

EMBODIMENT A telephone according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of the telephone according to the present invention. In Fig. 1, 14 is a telephone line (office line);
15 to 18 are lines, 19 is a hook switch, 20 is a ringer, 121 is a switch, 22 is an amplifier/filter,
23 is a receiver, 24 is a transmitter, 25 is a dial, 26 is a CPU, 27 is a memory, and 28 is a speech synthesis section.

The dialing operation of the telephone configured as described above will be explained below.

First, the caller picks up the handset 23, 24 (OFF
-HOOK), hook switch 19 then disconnects telephone line 14 from ringer 20 and connects it to line 15. The off-hook signal passes through the telephone line 14 to the exchange,
The data is then sent to the CPU 26 via lines 15 and 17. Thereby, switch 21 is controlled, and line 15 and line 1 are
6 is connected.

The caller then hears a dial tone through the receiver 23.

The caller then presses only one digit of the telephone number on the push-button dialer. Then, a dial signal is sent from the dial section 25 to the CPU.
Sent to 26th. First, the CPU 26 controls the switch 21 to connect the line 15 and the line 17, and the line 16 and the line 18. The beep will then stop. Next, the CPU 26 processes the dial signal, converts it into dial data, and stores it in the memory 27. At the same time, the CPU 26 calls up voice data corresponding to the dial, sends it to the voice synthesis section 28, and after converting it to a voice signal, connects the line 1B. 16, the signal is sent to the receiver 23 via the amplifier/filter 22.

After confirming the voice output, the caller presses the next digit of the telephone number if the number is correct. When the dial signal is sent to the CPU 26, the °CPU 26
The dial data of the previous digit is read from the memory 27, converted into a selection signal (dial pulse or multi-frequency code) corresponding to the telephone line 14, and sent to the exchange via the lines 17, 15 and the telephone line 14. Then, the inputted dial signal is processed and converted into dial data, and stored in the memory 27. At the same time, the voice data corresponding to the dial is called up and sent to the voice synthesis section 28, and after being converted into a voice signal, the line 1B , 16, and sends it to the receiver 23 via an amplifier/filter 22.

If the caller confirms the voice output and finds that the number is incorrect, press the correction key (here "*").
Press and then dial the correct number. Then,
First, a correction signal is sent to the CPU 26, and the CPU 26 erases the previous dial data, processes the next incoming dial signal, converts it to dial data, stores it in the erased memory address, and at the same time The voice data corresponding to is called up, sent to the voice synthesis section 28, converted into a voice signal, and then sent to the receiver 23 via the amplifier/filter 22.

Repeat the above steps to dial a series of phone numbers.

The caller dials the last digit, checks the voice output, and if it is correct, presses the enter key (here "#") to complete the dialing.

Then, the input signal is sent to the CPU 26, and the CPU 26 memorizes the dial data of the previous digit (last digit).
17.1, converts it into a selection signal (dial pulse or multi-frequency code) corresponding to the telephone line 14, and sends a call to the telephone line 17.1.
5. Send it to the exchange via the telephone line 14.

After that, the CPU 26 controls the switch 21 to connect the lines 15 and 16 to enable a telephone conversation.

As you can see from the above explanation, if you make a mistake when dialing, you can correct it immediately without having to go on-hook once. Also, corrections can be made for each incorrect phone number digit by digit, reducing dialing time. This makes dial operation convenient.

Furthermore, in this embodiment, the number of incorrect calls is reduced because the user not only dials a telephone number but also confirms the dialed number by voice output.

Further, in this embodiment, the confirmation was made using audio output, but the same effect can be obtained by using a display device such as a liquid crystal.

Further, although this embodiment uses a push-button dial telephone (pulse dial or multi-frequency code), the present invention can also be easily implemented in a rotary dial telephone by providing separate "correction" and "input" keys.

Effects of the Invention As described above, the present invention includes a storage circuit that temporarily stores dialed telephone numbers, an output circuit that outputs the telephone number to the caller, and a circuit that allows the caller to correct the telephone number. By providing a correcting circuit that can be used to dial the wrong number, if a wrong number is dialed, the incorrectly dialed telephone number can be easily corrected without ever going on-hook. It becomes convenient.
