The present invention relates to the invention of a text mobile phone that has a communication relay service for the hearing impaired and people who are hearing impaired or who are hearing impaired and a softway that can receive real-time transmission of the contents of the call using subtitles. It is about a communication relay service that helps the hearing-impaired person to communicate freely with the general public anytime, anywhere with his / her own voice and check the contents of the other party's call by text instead of hearing.

In general, a deaf or hard of hearing person uses a specially designed typewriter as a method of making a phone call with a general person, and directly sends a text message and a text message from a mobile phone. However, the typewriter telephone (TTY) is a method of transmitting using a V.18 modem in a general PSTN network. The mobile phone text message call method is difficult to use for the elderly deaf because of the problems of one-time call, real-time call impossibility, and inconvenience of use (one day typing). However, due to the present invention, but for hearing impaired, hearing-impaired, elderly people who can not speak because they have a hearing impaired, their voices are delivered to the other party, and the contents of the call are transmitted by voice and text subtitles for smooth communication life. It is to help them live.

The present invention is equipped with a caption request button on the mobile phone to access the subtitle transmission system and software such as H.324 mobile system, Mobile transmission, T.140 protocol.

 In order to communicate with the subtitle mobile phone, the subtitle transmission system has a mobile communication protocol, a user database, and an operator and a voice recognition system to convert the voice into text. It is equipped with a modem for transmitting digital signals, a text transmission server, etc., and the call is controlled by the ARS system, PBX, Operator, etc. for the public connection.

Figure 1 is a schematic diagram of the overall configuration for explaining the present invention, the hearing impaired and hearing-impaired people who do not hear the sound is to use a specially designed subtitle mobile phone 10 to talk to the general public. In other words, for the deaf, hard of hearing, and the elderly who can speak but cannot hear because they are hearing impaired, their voice is transmitted to the other party, and the contents of the other party's calls are transmitted through voice and text subtitles to maintain a smooth communication life. To make it possible.

In order to receive the subtitle (⑤), the sender and the receiver must be connected to the subtitle transmission system 30. In case of caption mobile phone user, press the specially designed caption request button to access the caption transmission system and make a call with the general public, and the public access the transmission system through the 700-line network and switch to the cell phone of the hearing loss person.

The caption mobile phone 10 is equipped with a caption request button to access the caption transmission system, and is equipped with software such as H.324 mobile system, mobile transmission, and T.140 protocol. The subtitle transmission system 30 has a mobile communication protocol, a user database, and an operator and a voice recognition system for converting a voice into a text so as to communicate with the subtitle mobile phone. It is equipped with a modem for transmitting digital signals, a text transmission server, etc., and the call is controlled by the ARS system, PBX, Operator, etc. for the public connection.

Therefore, the hearing impaired person using the special subtitle mobile phone 10 exchanges voices with the general person (①, ②) and make a call while the voice of the general person (③) is transmitted to the text real-time transmission system 30 and converted into a character ( ④) The converted character is transmitted (⑤) to the text subtitle mobile phone 10 of the hearing impaired so that it appears on the screen at a time similar to that of the voice (②) so that the call can be made in real time (converted to 175 characters per minute and transmitted).

2 is a block diagram of a subtitle mobile phone system according to the present invention. A typical mobile phone is composed of a transmitter, a receiver, a power unit, a display unit, a logic unit, and a power unit. The present invention includes a mobile transmission 100 installed in a mobile phone system and installs software to read codes coming from a voice recognition server. Will be displayed on the phone screen.

The output signal logically combined through the caption request button 150 is provided to the control unit 100 to request a real-time subtitle transmission service from the user's voice recognition server. In general, in multimedia communication, an electronic code called Baudot is used as a text communication method. In other words, V.18 modem is installed in PSTN, while mobile phone is equipped with T.140 Protocol and Mobile Transmission so that Ascii and Baudot can communicate with each other.

 As in a typical mobile phone, the reception signal processing unit 110 is controlled by a control unit, receives a radio signal from an antenna, and the demodulated signal is output as a voice signal through the receiver 111. At the same time, the caption mobile phone converts a signal coming from the voice recognition server into a text signal on the control unit 100 and displays it on the screen so that the user can receive the voice call and the subtitles at the same time. The transmission signal processing unit 120 is controlled by the control unit 100 and modulates a voice signal coming from the transmitter 121 into a wireless signal and transmits it through an antenna to transmit its own voice to the other party.

Referring to Figures 3 and 4 will be described the transmission process and overall system of the voice call subtitle.

In order to make a call while receiving a caption service, a hearing impaired person who uses the caption mobile phone 200 needs to be connected to the real-time caption transmission system 220 through the mobile communication base station 201 and the Korea Telecom 700-line network 231. The access method differs depending on the call origination and reception. First, as a method of making a call in the outgoing mode, when the caption 310 button is pressed while the mobile phone is powered on 300, the caption transmission system in which the user's database is constructed using the mobile transmission and the H.324 mobile protocol of the mobile phone is established. Connected to 210. If the connection is confirmed in the mobile phone and the other party's phone number is pressed and the user presses "SEND", the transmission system switches to the other party's phone number and the caller, receiver and operator make three-way calls. The operator can hear all the contents of the call, but does not directly participate in the call, but converts the call to the text through the voice recognition system and transmits the text subtitles to the deaf and hard of hearing. Therefore, the deaf persons can confirm the call contents by text simultaneously with the voice. If the Caption 310 button is not pressed, it is not connected to the transmission system but directly connected to the other party's phone via the mobile communication base station 201 (after entering the phone number 311), so that only a general voice call 321 is possible.

Secondly, it is a method of making a call while receiving a caption service in a receiving mode. The general public calls the subtitle mobile phone user in two ways: general voice call and voice + text subtitle call. If you press the phone number of the subtitle mobile phone directly from the regular phone will communicate only by the existing voice call. However, if you connect to the ARS message system 220 of the subtitle transmission system via the Korea Telecom 700 line network, enter the words "It is a text subtitle transmission service" and "Phone number you want to call" in the database provided in the ARS message system. "To the user. If you enter the phone number, the user's database is saved and the reception of the caption call is displayed on the screen along with the vibration (or bell). At this time, if the receiver possessing the caption mobile phone does not press the caption button 320, only the voice can be called, and if the caption button is pressed, the call 322 can be made by voice while receiving a text transmission service.

As described above, the present invention further includes an interface circuit that implements text communication software and simple logic operation in the existing mobile phone system, so that the mobile phone can be easily operated to access the caption transmission system, and to enable voice and caption communication. Do it. In modern society, the number of people who are hearing loss due to various factors such as industrialization and aging is increasing, which requires the construction of a new communication infrastructure. Although the hearing loss of the present invention is acquired, the new welfare communication service will be provided as a mobile phone freely available anywhere for the deaf and hearing impaired person who wants to make a phone call with the general public through their voice.
