The present invention relates to a method of button voice utterance of a telephone, and more particularly, to a method of generating a voice corresponding to a pressed key when a button of the telephone is pressed.

In general, various devices (keyboards, calculators, telephones, lubricators, etc.) equipped with a key input unit can be used by physically handicapped persons, especially visually handicapped people, by using specific markings to recognize the position of keys on a specific key. In this way, it is possible to recognize the position of key on a specific key so that the visually impaired can use various devices, but it is impossible to check whether the desired key is pressed correctly. This has risen.

As described above, a button apparatus of a conventional voice telephone apparatus in which a voice corresponding to a pressed key is generated when a key is pressed is described in Korean Patent Application No. 92-3292. However, the button device of the conventional voice telephone as described above has a problem in that the circuit is complicated and the manufacturing cost is increased and the voice is generated only by the key input only in a call state.

Accordingly, an object of the present invention is to provide a voice uttering method for uttering a voice corresponding to a button key signal pressed in various devices using a button.

Another object of the present invention is to provide a voice speech method for uttering a voice corresponding to a key signal pressed in a standby state or a call state in a telephone.

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

1 is a block diagram of an automatic answering system according to the present invention. The key input unit 10 generates key commands and key data for controlling the operation of a telephone by a user.

The central processing unit 20 receives the output of the key input unit 10 and outputs a voice data address corresponding to the number to control the voice information.

The line interface unit 30 is connected to a public telephone network through a telephone line, and interfaces ring signals, tone signals, and call voice signals between the telephone and the public telephone network. The ringer unit 40 has an input terminal connected to the line interface unit 40, and detects a ring signal outputting the line interface unit 40. The ring detecting unit 50 is connected to the ringer 40 and outputs a ring detecting signal to the CPU 20 when receiving a ring signal. The call path unit 70 is connected to the line interface 30 to process a voice signal and a tone signal at the time of the hook off. The audio unit 80 is connected to the call path unit 70 to receive a voice signal from a public telephone network or to process and receive a voice message. The speaker driver 90 receives the output of the ringer 40 and the audio 80 to generate an audible sound to the speaker 100.

The voice memory 40 records the announcement message, the message message, and the voice information as digital data. The voice processor 130 synthesizes the guide message, the message and the voice information stored in the voice memory 140 under the control of the central processing unit 20 into a voice signal and outputs the voice signal to the audio 80. The message received from the audio unit 80 is converted into digital data and stored in the voice memory 140. The microphone 150 outputs a voice signal generated from the subscriber to the audio unit 80. The tone decoder 110 decodes the DTMF signal received in connection with the call path unit 70 and digitally outputs the DTMF signal to the CPU 20. The dialing unit 120 converts the telephone number data output from the central processing unit 20 into a DTMF signal and outputs the DTMF signal to the call path unit 150. The display unit 160 displays each state under the control of the CPU 20.

Comparator 170 is connected to the audio unit 80 detects the presence of a voice and outputs it to the central processing unit (20).

2 is a flow chart for controlling voice utterance in the standby mode registration mode according to the present invention, a process of setting a registration mode when a registration key is input in the standby state, and a shortcut number after setting a registration mode in the registration mode setting process. When the phone number is input, the phone number is stored and stored in the dial buffer, and the phone number is stored in the phone number storing process. After the phone number is stored, the key value stored in the dial buffer is read from the voice address, and the voice is synthesized. It consists of a voice transmission process for transmitting voice.

3 is a flowchart for controlling voice utterance in a call mode according to the present invention, a dial key input checking process for checking a dial key input state in a hook-off state, and a dial when a dial key is input in the dial key input checking process It stores the key value in the dial buffer and increases the input pointer, and reads the key value stored in the dial buffer at the voice address, and synthesizes the voice to transmit the voice corresponding to the key value.

One preferred embodiment of the above-described configuration will be described in detail with reference to FIGS. 1 to 3.

In the speed dial function, voice utterance can be realized both when a speed dial is registered in a standby state and when dialing is performed in a call state. The voice speech realization is performed by a memory map as shown in Table 1 embedded in the CPU 20, and the operation thereof is as follows.

TABLE 1a

TABLE 1b

32-digit phone number can be stored.

10 buffers for storing 32-digit phone numbers.

Referring to FIG. 2, in the standby state, the central processing unit 20 proceeds to step 201 to check whether the hook switch is hooked off, and performs a call mode if the hook off is performed, and proceeds to step 202 if it is not hooked off. In step 202, the central processing unit 20 inputs a registration key (representing a memory key in the phone) from the key input unit 10. That is, an operation start key (press the registration start key twice when the memory key is pressed once is the registration end key.) If the registration key is not entered, perform step 201 again. If the registration start key is entered, go to step 203. In step 203, the number buffer shown in Table 1 is cleared to "0". In step 204, the registration dial buffer is cleared to "0", and in step 205, the input pointer is cleared to "0" and initialized. In step 206, the registration lamp is turned on and the process proceeds to step 207. In step 207, the central processing unit 20 checks whether the voice corresponding to the key is being output, and if it is not outputting the voice, proceeds to step 208 to turn off the voice output path and proceeds to step 209 to perform voice output. If yes, go to step 209. In step 209, the central processing unit 20 checks whether a registered key is input. If the registered key is input, the CPU 20 proceeds to step 210. In step 210, the CPU 20 checks whether the number buffer of the memory shown in Table 1 is 0. If the number buffer is 0, the CPU 20 proceeds to step 213. If the number buffer is not 0, step 211 Proceed to step 212 to specify an internal registration address for storing the phone number corresponding to the number stored in the number buffer.

In step 212, the contents of the dial buffer are stored in the designated internal registration address. In step 213, the registration lamp is turned off and the process proceeds to step 201. However, if the registration completion key is not input in step 209, the process proceeds to step 214, and if the shortcut signal is input. If the shortcut signal is input, the process proceeds to step 215 and checks whether the number buffer shown in Table 1 is 0. If it is not, perform step 207 again, and if it is 0, go to step 216 to store the shortcut value in the number and then return to step 207 again. If the shortcut key is not input in step 214, it is checked whether the dial number key is input. If the dial number key is not input, the process returns to step 207. If the dial number key is input, step 217 is performed. In step 217, the central processing unit 20 checks whether the number buffer is 0, and if it is 0, proceeds to step 207 again. If not, it returns the dial key value in step 219 to the memory dial shown in Table 1. Save to the buffer and proceed to step 220. In step 220, the key value of the dial buffer stored in the dial buffer is converted into a voice address, and the flow proceeds to step 221. After reading the voice data corresponding to the voice address, the voice processing unit 130 processes the voice and proceeds to step 222. do. In step 222, the central processing unit 20 turns on the audio output path and transmits the key value through the audio unit 80 → speaker driver 80 → speaker 100 as voice.

3, in the standby state, the central processing unit 20 examines the hook switch to check whether the call is in a call state. When the call is in the call state, the memory buffer is cleared to "0" in step 301, and in step 302. The input pointer receiving the dial key is cleared to "0", and in step 303, the execution pointer for dialing is cleared to "0" to perform dial initialization. In step 304, the hook switch is checked whether the hook is turned on. If the hook is turned on, the standby switch is performed. If the hook switch is turned on, the standby switch is performed. In step 305, it is checked whether a dial key is input. If no dial key is input, step 306 is performed. In step 306, it is checked whether the dial buffer is 0, and if it is 0, step 310 is performed, and if it is not 0, step 307 is performed. In step 307, if the input pointer and the execution pointer match or not, the process proceeds to step 308, and dials the key value of the dial buffer indicated by the execution pointer, and proceeds to step 309. In step 309, the execution pointer is increased by one and the process proceeds to step 310. In step 310, the central processing unit 20 checks whether or not the voice is output and returns to step 304 if the voice is being output, and proceeds to step 311 to turn off the voice output path if the voice is not being output. However, if the dial key is input in step 305, the input dial key value is stored in the dial buffer in step 312, and the flow proceeds to step 313. In step 313, the input pointer is increased by 1 and the flow proceeds to step 314, where the key value stored in the dial buffer is converted into a voice address, and the flow proceeds to step 315. In step 315, the voice processing unit 130 reads the voice data corresponding to the voice address and processes the voice in the voice processing unit 130 before proceeding to step 316. In step 316, the CPU 20 turns on the voice output path and transmits the key value through the audio unit 80 → speaker driver 80 → speaker 100 as voice.

Since the voice synthesis method not described herein is generally known, the description thereof has been omitted, and the above-described embodiment has been described above by way of example. However, the above-described embodiment may be implemented in all electronic devices having a key input unit.

As described above, in the speed dial function, the voice can be voiced according to a key input without registering a handset by activating a mode voice when registering a speed dial in a standby state and executing dialing in a call state. In addition, there is an advantage that the cost can be reduced by implementing the voice speech in software using a speech synthesis IC.
