Description

How to Receive Voice Messages from Fax Systems

The present invention relates to a method for receiving a voice message of a facsimile system, and more particularly, to a method for leaving a message to an absent recipient by converting a sender's voice into a text and then printing it in a facsimile system having a voice recognition function.

In general, a facsimile is a device capable of performing a simulated transmission since the fax data read from the document is transmitted to an external facsimile via a communication line or a fax data received from an external facsimile is printed out through a communication line.

The facsimile system is equipped with an internal telephone, so that not only facsimile communication but also telephone communication can be performed by sharing one communication line. / Automatic telephone switching mode, facsimile automatic receiving mode for receiving faxes automatically by first connecting fax line to communication line, firstly connecting the internal telephone to communication line, and receiving the call first by the receiver after mutual consultation There are various reception modes such as a facsimile manual reception mode that can receive a fax manually, and the user can select and use a reception mode according to a suitable communication method.

However, the above-described facsimile system can receive the fax data automatically and leave the fax data even when the recipient is absent. However, if the sender calls the receiver for a telephone call, the message cannot be left. Will not achieve.

In order to alleviate this inconvenience, a facsimile system with an answering machine has emerged, which allows the sender to leave a message through the answering machine even when the recipient is absent. It was a factor in raising the cost and also a barrier to the miniaturization of the facsimile.

Therefore, the present invention, in view of the problems of the prior art as described above by converting the voice of the sender to the character in the fax system to print out so that the sender can leave a message to the absent recipient without having an answering machine, The purpose is to enable the sender to achieve its intended purpose of calling the receiver.

It also aims to reduce the cost of the facsimile system and allow for a compact design.

As shown therein, an image input unit 20 for reading image data from an original through an image pickup device, and a predetermined image data. To operate the image processing unit 30 for performing image processing according to an algorithm, the engine unit 40 for driving various mechanisms such as rollers required for printing and document transfer, and the facsimile machine. Memory unit 50 for storing necessary various control programs (Firmware) and various data generated accordingly, a controller 10 for controlling each unit of the facsimile according to the execution of the control program, external facsimile and data Modem unit 60 for transmitting and receiving, and the modem unit 60 and an external public switched telephone network (hereinafter referred to as a PSTN network) (200) The LIU unit (Line Interface Unit) 70 which is in charge of the physical connection with the control panel, an operating panel (OPE) 80 having various keys and a display window, and a voice signal are received. The voice recognition unit 90 converts the voice into text by performing voice recognition.

The apparatus may further include a voice converter 91 for converting prestored voice guide data into a voice signal through a predetermined process and outputting the voice signal to the modem unit.

At this time, the voice recognition unit 90 analyzes the sound of the voice signal received through the communication line of the PSTN network 200, extracts the feature information, and recognizes the voice by comparing with the previously stored feature pattern. Print character information.

The controller 10 receives the text information and controls the engine unit 40 to print out the message converted to text.

2 is a flowchart illustrating a voice message receiving method of a facsimile system according to the present invention.

Referring to FIG. 2, in the voice message receiving method of the present invention, after a ring signal is detected through a communication line, a reception signal determination for determining a type of a signal to be received subsequently is determined according to whether a facsimile transmission sound (CNG) is detected. Step S10; If it is determined that the signal to be subsequently received is a voice signal, a call intention delivery step of ringing a bell while checking a state of a hook switch for a predetermined time (S20); If the hook switch is not off within the set time (S30), the voice guide step of providing a voice guidance for inviting the receiver to leave a message and notifying the sender of the receiver through the communication line (S30); A voice recognition step (S40) of performing voice recognition with a voice signal received through the communication line from the transmitting side; And a text output step (S50) of printing and outputting a character corresponding to the voice recognized through the voice recognition step.

At this time, if the fax transmission sound is detected further includes a fax receiving step (S60) for receiving the fax data through the communication line.

The receiver further includes a telephone call step (S70) for carrying out a call when the hook switch is turned off while the receiver picks up the receiver while ringing the set number of times.

Hereinafter, a method of receiving a voice message in a facsimile system having the above configuration will be described in detail.

First, when the transmitting side dials a receiving telephone number to be called by the terminal apparatus (telephone or facsimile), a ring signal is transmitted to the receiving terminal apparatus through a communication line of the PSTN network 200 and is called.

In the facsimile system to which the present invention on the receiving side is applied, it is checked whether a facsimile transmission sound (CNG) is detected after the ring signal is detected (S10).

At this time, if the sending terminal device is a facsimile, the facsimile transmission sound is sent to the receiving side. If the facsimile transmission sound is detected through the communication line, it is determined that the signal to be received is not a voice signal but a fax data signal. The fax data received through the LIU unit 70 and the modem unit 60 is output to the engine unit 40 and printed (S60).

However, if the sending terminal is a non-facsimile telephone, the receiving side facsimile does not detect the facsimile transmission sound, so it determines that the next signal to be received is a voice signal and rings the telephone to make a telephone call between the sender and the receiver. Notify the recipient of the phone call of the desired (S20).

At this time, the controller 10 sets an arbitrary variable to the counter N and initializes it, and then rings a pseudo bell while incrementing the counter N (S21, S22, S23) and counts the counter N. While comparing the value with a predetermined number of times stored in the memory unit 50, the telephone ring is made until the count value is equal to the set number of times, and the on / off state of the hook switch is checked (S24 and S25).

If the receiver lifts the handset while the telephone ring is ringed by the set number of times, the hook switch is turned off, the controller 10 allows a telephone call to be made between the sender and the receiver (S70).

However, if the hook switch is not turned off while the pseudo bell rings for the set number of times, the controller 10 determines that the receiver is absent and converts the voice guidance data into a voice signal through the voice conversion unit 91 and then the LIU unit. Since the output through the 70 and the modem unit 60, the sender is notified that the receiver is not present and voice prompts to leave a message (S30).

Then, the voice signal is received from the transmitter and output to the voice recognition unit 90 to perform voice recognition and output text information corresponding to the recognized voice (S40).

Here, the voice recognition unit 90 analyzes the sound of the input voice signal, extracts the feature information, and compares the feature information with the feature pattern previously stored in the memory unit 50 to recognize the voice, and corresponding character information. Outputs

The controller 10 receives the text information output from the voice recognition unit 90 and controls the engine unit 40 to print and output a message according to the text information (S50).

In this way, the voice of the sender is converted into text and printed out, thereby leaving a message to the absent recipient.

Of course, such a facsimile system allows a user to place an original on an original tray and operate the operation panel 80 to read fax data from the original through the image input unit 20 and process the image in the image processing unit 30. After that, it may be transmitted to an external facsimile through the modem unit 60 and the LIU unit 70.

As described above, according to the present invention, a facsimile machine without an answering machine converts a sender's voice into a text and prints the message to a recipient who is absent by printing. It is effective to achieve the purpose.

In addition, the cost increase factor of the facsimile system and the obstacle of the miniaturized design are eliminated due to the need for the answering machine to leave the voice message of the conventional sender.
