Description

Transmission of the sound of a language for one-button dialing system}

The present invention implements a speed dial function and a function of transmitting a voice of a telephone, and when a shortcut button is pressed, a dial signal DTMF and a voice are transmitted together. By doing this, it is possible to transmit a pre-recorded speech (voice) in a situation where speech cannot be spoken.

A conventional method for transmitting a voice in a telephone includes a method of automatically transmitting a recorded message by an automatic dial in a telephone terminal device (Public Publication No. 1998-083761), a method of sending an emergency message of a telephone (Public Number 95-22662), and the like.

In all the above methods, when a shortcut button is pressed, a dial signal is automatically transmitted to make a call, and when there is a response (hook off) of the answering party, the system detects this and automatically transmits a pre-stored voice. FIG. 1 shows a conventional method of transmitting voice. When the telephone is set to the automatic transmission mode 101, the dial signal 102 is transmitted to a predefined telephone number. Thereafter, the other party's situation is judged (103), the call is repeatedly made for a predetermined time when the call is in progress or when the call cannot be answered. 104).

In this method, in order to confirm the call availability state 103 of the other party, a detection device for whether the other party is hooked off or busy is required. In addition, there is no method for transmitting voice during a conversation with the other party, and there is no method for repeatedly transmitting voice in one call connection state.

The main object of the present invention is to configure a speed dial device for transmitting voice and dial signal (DTMF) dual tone multifrequency (DTMF), it is possible to call and pre-stored voice transmission with a single button, recording in one call connection state This allows you to send the voice whenever you need it.

In order to achieve the above object, it is possible to configure a speed dial device to input and store a voice and a phone number, and to press one speed button to transmit the dial signal DTMF and the recorded voice simultaneously or continuously. do.

An embodiment of the present invention will be described with reference to the accompanying drawings.

2 is a method of transmitting a voice and dialing signal (DTMF) according to the present invention, and according to a general telephone call procedure, when a user presses a handset (hook off) and presses a shortcut button once, a dial signal corresponding to a telephone number of the other party ( DTMF) and the recorded voice are transmitted together (201). In this case, the dial signal DTMF and the recorded voice may be simultaneously transmitted, or the dial signal DTMF may be transmitted first, and the recorded voice may be sequentially transmitted.

In the telephone exchange, only the dial signal DTMF is detected through a filter. The dial signal DTMF uses a combination of a low frequency (697Hz-941Hz) and a high frequency (1209Hz-1477Hz). The frequency of the voice is a low frequency of about 120 Hz for males and about 250 Hz for females, so that only the dial signal DTMF can be detected using a filter at the exchange. Therefore, even if the dial signal DTMF and the recorded voice are simultaneously transmitted, the formation of the call path is not affected. For example, we know from experience that even if you are calling from a noisy public telephone near the road, there is no effect on the formation of the call.

After the formation of the call 202 is completed, the recorded voice may be transmitted 204 at any time, and the voice call 207 may also be made. In order to transmit the recorded voice, when the shortcut button is pressed once as in step 201, the dial signal DTMF and the recorded voice are transmitted together, and the dial signal DTMF generated after the call path is formed is a call. It does not affect the state of the furnace and is only heard by the other party as a dial tone sound. At this time, if the dial signal (DTMF) sound interferes with listening to the recorded voice, rest the recording for a short time (during the DTMF signal transmission time) before recording the voice, or transmit the dial signal (DTMF) first. In addition, it is possible to configure to transmit the recorded voice in succession.

3 is a block diagram showing the structure of a telephone 300 having a speed dial function for transmitting a voice and dial signal DTMF according to the present invention. Under the control of the central processing unit 303, the voice to be transmitted is digitized through the voice input circuit 304 and stored in the memory 308. In addition, the phone number for the speed dial is stored in the memory 308 through the keypad 306, and at this time, the phone number input through the display device 307 can be checked.

When the handset is hooked off for a telephone call and the shortcut button on the keypad 306 is pressed once, the central processing unit 303 drives the dial signal (DTMF) transmitting circuit 302 and the voice transmitting circuit 305. The dial signal DTMF and the recorded voice are transmitted to the telephone lines Tip and Ring through the call circuit 301. Then, under the control of the central processing unit 303, it is possible to transmit the dial signal DTMF and the recorded voice simultaneously or continuously.

4 shows a speed dial device 501 having a function of transmitting a voice and a dial signal DTMF according to the present invention, which is connected to and disconnected from a telephone line of a general telephone 401. . As shown in FIG. 3, the voice input circuit 506 and the keypad 508 are used to store voice and telephone numbers in the memory 507 under the control of the central processing unit 505. In this case, the phone number input through the display device 504 may be checked. When the handset of the telephone 401 is hooked off for a telephone call and the shortcut button on the keypad 508 of the speed dial device 501 is pressed once, the central processing unit 505 transmits a dial signal DTMF circuit. The 503 and the voice transmitting circuit 502 are driven to transmit the dial signal DTMF and the recorded voice over telephone lines (Tip, Ring). In addition, it is possible to transmit the dial signal DTMF and the recorded voice simultaneously or continuously under the control of the central processing unit 505.

By implementing the speed dial function to transmit voice and dial signal (DTMF) in the phone, it is possible to form a call path and transmit voice call and recorded voice with one speed button, and recorded at any time. Can transmit voice In other words, in a situation where it is difficult to speak, one shortcut button can make a call and deliver a pre-stored voice.
