The present invention relates to a mobile communication terminal and a method for outputting a received text message as a voice, and more particularly, a mobile communication terminal capable of converting and outputting a voice signal received from a counterpart during a call or a voice message received during a non-call. And to a method.

Due to the characteristics of the mobile communication terminal, the place of call is frequently changed, and thus it is often inadequate to perform a voice service. For example, when one or both of the sender and the receiver are located in a noisy environment, such as a public place or a meeting place, it is difficult to listen to the other party's voice or output his or her own voice.

In order to solve this difficulty, the conventional mobile communication terminal implements a short message service (SMS) or a text receiving service. Here, SMS means that if the other party is located in an area where the call is difficult or in an unserviceable area, if the caller stores a voice message or a phone number in the SMS mailbox, the other party returns to the serviceable area and the voice message or phone number, etc. This service allows you to check. In addition, the text receiving service is a service that allows the mobile communication terminal to check the message when the other party transmits the short message.

However, such an SMS mailbox function cannot be used in real time, and there is a inconvenience that a recipient needs to confirm it later. In addition, there is a problem that the text receiving service is also impossible to perform a real-time two-way service, and the information can be transmitted only in a specific direction allowed after a certain time has elapsed. In addition, since the type of service is determined unilaterally according to the caller's request, there is a flaw in that the receiver cannot provide an appropriate service.

Moreover, since the deaf cannot hear the other party's voice, the conventional mobile communication terminal cannot provide a real time call service to the deaf.

In order to solve such a problem, Korean Patent Application No. 2002-0020106 discloses that when a user of a mobile communication terminal is in an inappropriate environment for listening to voice, the voice service is changed to a real-time text service, and the caller is inappropriate for transmitting voice information. We propose a technology that converts the text information of the caller to a voice signal and delivers it to the receiver when the environment is in operation.

First, the caller's voice signal transmitted from the calling mobile terminal is processed in a predetermined form and transmitted to the base station. At this time, the base station accepts the user's request from the receiving mobile terminal and performs the text information service.

That is, the base station confirms that a text information service request is generated from a user, and then converts a voice signal received through the base station after being transmitted from the calling terminal to text information using a voice recognizer. Is transmitted to the receiving terminal and displayed on the LCD screen, the user of the receiving terminal can receive the voice signal transmitted from the counterpart as real-time text information.

However, in the case of the voice and text conversion service method using the conventional mobile communication terminal as described above, since the base station is implemented to perform the same service collectively, it causes a rise in the mobile communication service fee accordingly. From the point of view of users who do not want the service, there was a problem that the base fee collected by the mobile carrier is unfairly raised.

The present invention has been made to solve the above problems, to provide a mobile communication terminal and method that can convert the voice signal received from the other party during the call to the text in real time and output.

Another object of the present invention is to provide a mobile communication terminal and method which can easily perform a real-time call even by a hearing impaired by converting and displaying a voice signal of a counterpart received during a call.

Another object of the present invention is to provide a method of receiving a call service without paying additional service fee to the mobile communication company by converting and displaying the voice signal of the other party in real time in the mobile communication terminal in real time.

In order to achieve the above object, the present invention provides a voice for converting an input voice signal into a text signal and outputting a text signal in a mobile communication terminal that performs voice and text calls with a counterpart according to a user's input through a keypad. Character conversion unit; A controller for transmitting a voice signal of the other party to the voice / text converter and controlling the display of the text signal converted by the voice / text converter; And a display unit for displaying a text signal transmitted by the controller.

According to an aspect of the present invention, there is provided a method of performing a voice and text call with a counterpart through a mobile communication terminal, the method comprising: setting a voice / text call mode according to a user's instruction; In the voice / text call mode, converting a received voice signal into a text to display on a liquid crystal display and simultaneously outputting the received voice through a speaker; When the user instructs the end of the call or the other party ends the call, a third step of deleting the characters displayed on the LCD screen and ending the call.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

A liquid crystal display (LCD) 50 for displaying text messages and various kinds of information, and a baseband signal transmitted by the control unit 40 is converted into a high frequency signal to be transmitted to the outside and received through a base station. Converts a frequency signal into a baseband signal and connects it to the control unit 40, and converts a voice signal of the other party received through the radio frequency processing unit 60 into an audio signal suitable for the control unit 40. The audio processing unit 70 and the control unit 40 converting the audio signal transmitted by the control unit 40 and the audio signal transmitted by the control unit 40 to a signal suitable for the radio frequency processing unit 60 and transmitting the signal to the radio frequency processing unit 60. Speaker 80 for outputting a sound signal transmitted by the outside, and a microphone 90 for receiving a sound signal from the outside.

Here, the voice call service allows the user to perform a voice call with the other party in real time through the mobile communication terminal, and the voice / text call service uses the text signal of the other party to which the mobile communication terminal in which the communication connection is established with the other party is received. The output is converted.

The keypad 10 receives and transmits a user command related to a call and various additional services to the controller 40. That is, the user presses a key on the keypad 10 to set the mobile communication terminal to a voice call mode or voice. / Text Call Mode.

The voice / text converter 30 converts the voice signal transmitted by the controller 40 into text and transmits the text to the controller 40.

The controller 40 controls the provision of a call and various additional services according to a user's instruction input through the keypad 10. The operation thereof will be described in detail as follows.

When the user instructs to set the voice call mode by pressing a key, the controller 40 sets the mobile communication terminal to the voice call mode so that the user can make a voice call with the other party. When the voice call mode is set as described above, when the user instructs the voice / text call mode to be set using the key, the controller 40 sets the mobile communication terminal to the voice / text call mode.

Alternatively, the user may set the voice communication mode after setting the mobile communication terminal to the voice / text call mode using the key.

As described above, when the mobile communication terminal is set to the voice / text call mode, when a voice signal is received from the counterpart, the controller 40 transmits the received voice signal to the voice / text converter 30. At this time, when the voice / text converter 30 converts the input voice signal into a text signal and outputs it to the controller 40, the controller 40 converts the text signal converted by the voice / text converter 30 into a liquid crystal. Display on the screen 50.

The controller 40 outputs the voice signal received from the other party through the speaker 80 even in the voice / text communication mode. That is, in the voice / text call mode, the controller 40 displays the voice signal of the other party as text on the LCD screen 50 and simultaneously outputs the same through the speaker 80.

A process of converting the voice of the other party on the call into a text and providing the same to the user by the mobile communication terminal having the above configuration will be described in detail with reference to FIG. 2.                     

As shown in FIG. 2, when a user makes a call to the other party through a mobile communication terminal or receives a call received from the other party through the mobile communication terminal, the user uses a key to receive a voice / text call service. When instructing the setting of the text call mode, the mobile communication terminal sets the voice / text call mode (S201).

In the voice / text call mode, when the voice signal of the other party is received (S202), the mobile communication terminal converts the received voice signal into a text and displays it on the LCD screen and simultaneously outputs the received voice through the speaker (S203). . At this time, even if the number of characters output on the LCD screen exceeds one screen due to the reception of the other party's voice signal for a predetermined time or more, the mobile communication terminal continuously converts the received voice signal into characters and displays them on the LCD screen. Let's do it. In this case, the user can check the characters output on the LCD screen while moving the pages of the screen using the keys.

In the state of outputting the received voice as text as described above, the mobile communication terminal determines whether the user's voice is input through the microphone (S204). It is determined whether there is a call termination instruction or the other party terminates the call (S205). If it is determined that the call is terminated by the user or the other party ends the call, the mobile communication terminal deletes the characters displayed on the LCD screen and ends the call (S206).

If it is determined that the call is not terminated by the user and the call is in progress, the mobile communication terminal proceeds again to the process of receiving a voice signal (S202).

When the user voice is input as a result of the determination in the voice input determination process (S204), the mobile communication terminal transmits the input voice signal to the counterpart and maintains the output state of the characters displayed on the LCD screen before the voice is input (S207). . Subsequently, the mobile communication terminal determines whether the voice signal of the other party is received (S208). If the voice signal is received as a result of the determination, the process proceeds to the text output process (S203).

If the voice signal is not received as a result of the determination in the voice reception determining process (S208), the mobile communication terminal proceeds to the process of determining whether to terminate the call (S205).

On the other hand, even when listening to the voice message of the other party received by the mobile communication terminal during the non-call, the mobile communication terminal converts the received voice message to the text in the voice / text communication mode and displayed on the LCD screen.

Although the technical spirit of the present invention has been described in detail according to the above-described preferred embodiment, it should be noted that the above-described embodiment is for the purpose of description and not of limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.

As described above, the present invention converts and displays the voice signal of the other party into a text in real time in the mobile communication terminal, thereby providing a voice / text call service at the same rate as the usage fee of the voice call service. It can increase the utility and commerciality of.
