Voice message exposure prevention method of the phone according to the present invention for achieving the above object is a specific subscriber number input step of setting and registering a specific subscriber number, and the relative subscriber number received before the voice message when receiving an automatic response message and the specific The number comparison step for comparing the number set in the subscriber number input step, the number comparison result, the separate message storage step for storing the received voice message in a separate contracted memory area when the received number and the set number match, and the playback function If it is selected, the number input request step for requesting the number input for confirming the specific message, comparing the input number with the set number and confirming whether or not the match, and confirming whether the match result number and the set number Voice message from a specific subscriber stored in a specific area of the memory. The reading is characterized in that it is configured to include a voice message output step of outputting to the speaker to convert the voice message the voice message read out step, and the read signal into audible sound.

That is, according to the present invention having the above-described configuration, when the voice message recorded from a specific registered subscriber number registered in advance is stored in a specific memory area and the voice message playback function is selected, a guide message for confirming the stored voice message from the specific subscriber is selected. When the subscriber number input is completed, the voice data storage unit reads the voice data stored in the specific memory area and outputs the same through the speaker.

Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.

Figure 2 is a block diagram showing the internal configuration of a telephone with a voice message exposure prevention function according to an embodiment of the present invention.

In FIG. 2, the same reference numerals are assigned to parts performing the same functions as those of FIG.

In the drawing, reference numeral 20 denotes a keypad provided with a setting key 20a for setting an automatic answering function and a voice message reproducing function, a numeric key 20b for inputting a subscriber number, and the like. Subscriber number storage unit for storing the subscriber number input through the numeric key (20b) of, 22 outputs a contracted code signal corresponding to the DTMF signal of the subscriber number data applied through the trunk line connection port (1) The DTMF receiving circuit 23 is a voice data storage unit for recording and storing a voice message received from the other subscriber, and 24 is a display unit for displaying a voice message when the voice message is recorded and stored in the voice data storage unit 23.

In the drawing, reference numeral 25 denotes a digital signal processor (DSP) for reading voice data stored in a specific memory area of the voice data storage unit 23 according to a predetermined control signal, and 26 denotes this DSP. A codec (COder-DECoder) for decoding a digital voice data signal output from 25 into an analog voice signal, 27 amplifies a voice signal output from the codec 26 on the basis of a predetermined control signal This is an audio amplifier output to the speaker 28 connected to.

In the drawing, reference numeral 29 denotes a voice guidance message storage in which a plurality of voice guidance messages are stored, and 30 denotes a voice message received from a registered subscriber number in a specific memory area and a voice message playback function is set. The microprocessor checks the subscriber number input and controls the playback output of the corresponding voice message.

Next, the operation of the device having the above configuration will be described with reference to the operation flowchart shown in FIG.

First, when a ring signal is received in a state in which a specific subscriber number requiring security for a voice message is registered and set in the subscriber number storage unit 21 (ST1), the microprocessor 30 sets an automatic response function. If the automatic answering function is not set (ST2), the general call function is performed (ST3). If the automatic answering function is set, the call is switched off-hook and the recording guidance message (for example, the message is left). Please enter your phone number and record it, and when the recording is completed, enter '#'.) (ST4).

When the DTMF signal corresponding to the subscriber number is received according to the recorded announcement message (ST5), the microprocessor 30 reads the number data registered in the subscriber number storage 21 (ST6), and receives the received subscriber. When the number data and the registered number data are compared and judged (ST7), if the determination result does not match, the received voice message is recorded and stored in the voice data storage unit 23 (ST8). The message is stored in a specific memory area of the voice data storage unit 23. (ST9)

On the other hand, when the '#' key is received following the voice message received (ST10), the microprocessor 30 sends a recording completion message (recording is completed) to the other party (ST11), The call path is blocked through the call path connection unit 6 (ST12), and the display unit 24 indicates that voice data is stored (ST13).

Thereafter, when the user selects the setting key 20a of the keypad 20 to reproduce the voice message (ST14), the microprocessor 30 notifies that there is a recorded message received from a specific subscriber and that the voice has been recorded. In order to check the message, for example, a message for inputting the subscriber's telephone number is output. (ST15)

On the other hand, when the user completes the number input by inputting the '*' button with the subscriber number according to the guide message (ST16), the microprocessor 30 receives the number data registered in the specific subscriber number storage unit 21 In step ST17, the registered subscriber number and the subscriber number input by the user are compared and determined (ST18). If the determination result does not match, the microprocessor 30 drives the DSP 25 to drive control. By reading the voice data stored in the general memory area of the voice data storage section 23 together with the error message, the corresponding message is converted into an audible voice signal through the codec 26 and outputted to the speaker 28 (ST19). ), If the determination result is matched, a predetermined control signal is output to the DSP 25 so that the voice data stored in a specific memory area of the voice data storage unit 23 is read out, Voice messages from a particular subscriber set capability is switched via the codec 26 to the audio sound signal is controlled so as to be output to a speaker (28) (ST20).

That is, according to the embodiment, a voice message received from a specific registered subscriber number registered in advance is stored in a specific memory area, and when a voice message reproducing function is set, a guide message according to a specific subscriber number input is outputted. When the input is completed, the registered subscriber number is compared with the inputted subscriber number, and if it matches, the voice message stored in the specific memory area is read and converted into an audible voice signal, so that only the user who knows the specific subscriber number You can check the stored voice data from.

In addition, this invention is not limited to the above-mentioned embodiment, It can implement in a various deformation | transformation in the range which does not deviate from the technical summary of this invention.

As described above, according to the present invention, a voice message stored from a specific registered subscriber number registered in advance can be confirmed only by a user who knows the specific subscriber number, thereby preventing the exposure of the recorded specific voice message in the telephone. The voice message exposure prevention method can be realized.
