And a coding and decoding unit 19 for coding and decoding the character data output from the control unit 11 and the external input character data.

Then, the transmission and reception unit 2 is a modem unit for transmitting the coded character data from the character transmission unit 1 to the telephone line matching unit 5 and the acoustic coupling unit 3 or bidirectional transmission in the opposite direction thereof. (21), a voice transmitter 22 for transmitting the acoustic data from the acoustic coupling unit 3 and the voice data from the voice converting unit to the telephone line matching unit 5, and the telephone line matching unit 5; The voice receiver 23 for transmitting the collected sound data to the acoustic coupling unit 3 and the telephone line state detected through the telephone line matching unit 5 are transmitted to the control unit 11 in the text transmitting unit 6. The telephone line state detection unit 24 and the ring detection unit 25 for transmitting the ring signal from the telephone line matching unit 5 to the control unit 11 in the text transmission unit 6 are provided.

Looking at the detailed operation of the communication device having a configuration as described above, the voice conversion and sound conversion transmission of the text according to the present invention are as follows.

First, the text communication operation, which is a basic function of the present invention, is performed when the mode selector 18 is set to the text transmission mode, when a person of the same class, particularly a deaf person, enters a text through the text input unit 12. 11 indicates this to the character display unit 14 under the control of the display control unit 15, and at the same time, the other communication device to be coded by the coding and decoding unit 19 to be transmitted to the telephone line via the modem unit 21. To be displayed. Similarly, the character data sent from the other party is displayed on the character display unit 14 by the control unit 11 via the telephone line matching unit 5, the modem unit 21 coding and decoding unit 19.

In addition, when using a general telephone with a text communication, that is, if you carry out the communication device according to the present invention outside, the hearing impaired, etc. can not use a general telephone, so the sound conversion through the mode selection unit 18 After setting to the mode, the handset of the communication apparatus according to the present invention and the handset of a general telephone (such as a public telephone) are connected in reverse.

In other words, the handset receiver of the communication device according to the present invention and the handset of the general telephone handset contact each other so that the handset transmitter of the communication device according to the present invention and the handset of the general telephone handset come into contact with each other. 11) and the coded character data passed through the coding and decoding unit 19 and the modem unit 21 are converted into an acoustic signal which is an analog signal in the acoustic coupling unit 3, which is converted into a telephone line of the voice transmitter 22. Since it is output to the handset talker of the general telephone through the matching unit 5, the general telephone recognizes it as a kind of voice signal and transmits it to the counterpart communication device so that it is displayed as text data in the counterpart communication device. It is inputted from the receiver of the telephone handset to the voice receiver 23 of the present invention and converted into text data coded by the acoustic coupling unit 3. Since in characters transport unit 6 displays data of a problem it is possible to issue the data transmission and reception using the external standard telephone.

Next, when the other party is provided with a communication device for which text communication is not possible, the operation of transmitting the voice message in one way by the side using the present invention will be described. The mode selection unit 18 is used to enter the voice transmission operation mode. When the user inputs the text data, the controller 11 displays the text data on the text display 14 and temporarily stores the text data in the buffer, and transmits a message informing the counterpart of the one-way voice communication. Then, the text data is transmitted to the voice conversion matching unit 17 together with the control data so that the voice conversion unit 4 is converted into a voice signal, and then the converted voice is transmitted to the other party through the voice communication unit 22 and the telephone line matching unit. To be delivered.

In addition, when making a general voice call, if the handset in which the voice transmitter 22 and the voice receiver 23 are built-in is hooked off, the voice communication unit 1 starts the user's direct voice communication to the control unit 11. When the signal is notified and the call signal is output through the main control unit 11 and a call connection is made, the call is performed by the user's development using the voice transmitter 22 and the voice receiver 23, and the call is finished. When it is turned on, the voice communication unit 1 notifies the control unit 11 to inform that the voice communication has been released.

On the other hand, when the other party calls in the call, the ring detection unit 25 detects the ring signal through the telephone line matching unit 5 and transmits it to the control unit 11, whereby the control unit 11 connects the call once. After receiving a character reception request code, which is a unique encryption code indicating that text transmission is possible from the other terminal, the control unit 11 determines and performs text communication through the text transmission unit 6 or the acoustic coupling unit 3. If the request code is not received within a certain time, the general voice communication is performed.

If you are hearing impaired, check the communication method of the other party's communication device through the character display unit 14, if it is confirmed that the general telephone (voice communication only), delivers the pre-stored voice message and press the designated key to hook-on communication Ends.

As shown in FIG. 2, the mode selection unit 18 may be selected by selecting the mode selection unit 18 connected to the control unit 11. However, the character input unit 12 sets the operation mode. A method of inputting a command in advance may also be a preferred embodiment.

3 is a schematic overall flow chart showing a method of operating a communication apparatus capable of voice conversion and sound conversion transmission of texts according to the present invention, which is controlled by a control program mounted in the control section 11 in the text transmission section 6; Is performed.

When a start signal such as a power source for driving a communication device according to the present invention is applied, values such as a memory buffer are initialized and an operation mode is set using the mode selection unit 18 or the character input unit 12 (31). , 32).

Then, it checks whether or not the setting state is the communication using the text (33), and if the communication is not the text, the general voice communication using the general telephone function, the voice transmitter 22, the voice receiver 23 and the voice communication unit ( After the general call is made using 1), the call ends as the call is released (37).

As a result of the check 33, when the character communication function is set, the type of the character communication method is checked (34), and when the character and the character are set to the communication method using the conversion into sound data, the character is transmitted. After using the unit 6 and the acoustic coupling unit 3 to perform communication using only the character and the conversion communication into the sound of the character, the process ends as the call is released (35).

In addition, if the result of the inspection (34) is set to the voice conversion communication of the text, the text transmission unit 6 and the voice conversion unit 4 is used to convert the text input into the voice and perform a one-way communication. The call then ends as the call is released (36).

4 is a detailed process flowchart of text communication (35 in FIG. 2) processing.

Looking at the process of performing the text communication with reference to the drawings in detail, first, attempts to call to the other party to communicate (41), detects the call connection process is displayed on the text display unit 14 (42, 43), Investigate whether the call becomes available (44).

As a result of the survey 44, if the call is not available, the process returns to step 41 to retry the call. If the call is available, it is checked whether the received message from the other party is stored in the storage unit 16. (45), if there is a received message, the presence or absence of the message is displayed on the character display unit 46; Return to (45) (46 to 48). Here, the output of the content of the received message can be displayed on the text display unit 14 in text form under the control of the control unit 11, and can be listened to as a voice. That is, in order to listen to the received message by voice, a text message stored in the reception buffer of the storage unit 16 is sent to the voice conversion matching unit 17 under the control of the control unit 11, and the data signal for conversion to voice. The voice conversion unit 4 converts the received message into a voice and converts the received message into a voice, and then listens to the voice conversion unit 23.

On the other hand, if there is no received message or the user does not input a content output command even though there is a received message (45, 47), the user receives a keyboard operation signal for a call (49), the contents of the keyboard input signal to control the operation If the control key driving signal is input (50), and if the control key does not operate, it is a keyboard input having the contents of the transmission message and is displayed on the character display unit 14 and stored in the transmission buffer (51, 52).

Then, it checks whether to correct the keyboard input contents (54), corrects the contents when the correction request signal is input (54), and returns to the step (49) for receiving the keyboard driving signal, if there is no item to correct the contents Immediately returning to step 49 where the keyboard drive signal is input.

In addition, if the operation of the control key is examined by checking the keyboard input contents (50), it is checked whether the control key is driven to transmit the input message (55), and whether it is the input of the control key which commands the input message transmission (56). In the case of a command requesting communication completion, the call is released and terminated (58). Otherwise, the control operation is performed (57), and the control unit returns to the step of receiving the keyboard driving signal (57).

As a result of the survey 55, if the input of the control key for input message transmission is input, the input message is coded by the coding / decoding unit 19 in the text transmission unit 6, and after coding, the modem in the transmission / reception unit 2 A digital / analog conversion is made in section 21 (59, 60).

Then it is checked if the text is to be converted to sound and transmitted (61), if it is not changed to sound, the input message is transmitted (64), and the process returns to the step (45) to check if there is a received message from the other party, If it is to be transmitted, the problem data is converted into an analog signal and transmitted as an acoustic message (62, 63), and the process returns to the step (45) for checking whether there is a received message from the other party.

FIG. 5 is a detailed processing flowchart of the voice conversion communication process (36 of FIG. 3) for converting and transmitting text data into voice. Referring to the drawings, the detailed processing thereof is as follows.

First, the user inputs the keyboard drive signal of the user and checks whether the control key is input (71, 72). If the control key is not input, the message is displayed on the text display unit 14 and stored in the transmission buffer (73, 72). 74, the keyboard signal input step 71 is returned. If the keyboard input content is corrected, the content is corrected (76), and the keyboard signal input step 71 is returned.

By the way, if the keyboard signal is the control key 72, if the input mode of the control key is completed (77) and if it is not completed, the control operation is performed and the control panel returns to the keyboard signal input step 71. Investigate whether the transmission of the additional message is performed in the process of communication (79), and if it is not the additional transmission message, it attempts to transmit for the first time. The text is displayed on the character display unit 14, and it is checked whether a call is connected and call is possible (83). If the call is not available, the call is not connected and the call is attempted again. If the call is available, the call is connected. Therefore, the first message is a recorded notification message indicating that the message is sent by the disabled as a primary message. 84, and transmits the transmission message stored in the transmission buffer to the voice conversion unit 4.

However, as a result of the investigation (79), in the case of transmission of a message added to the existing communication process, a notification message recorded immediately as a basic message is immediately transmitted without performing a call connection process (84). The data is transmitted to the voice conversion section 4 for the transmission message stored in the buffer.

The voice conversion unit 4 synthesizes the voice data stored in the form of mutated sounds and transmits the inputted text data as voice (86), and further checks whether there is a message to be transmitted (87). If present, the process returns to the step 71 of inputting the keyboard drive signal, and if there is no message to be transmitted, the call is released (88) and ends.

Therefore, the present invention made as described above, the communication terminal device mainly used by persons with disabilities, etc., by adding a function of the sound transmission to enable communication using an existing public telephone, etc., voice that can also be received in a general telephone It can be transmitted in the form of a message, and has an excellent effect of being used as an effective means of informing an urgent situation.
