FIG. 1 is a network diagram illustrating a spam voice message blocking system according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 1, a spam voice message blocking system includes a spam voice message blocking apparatus 100 and a caller terminal 200. Here, the spam voice message blocking device 100 and the caller terminal 200 may be connected through a communication network.

The spam voice message blocking device 100 may determine whether the voice message received from the calling terminal 200 is a spam message and display a warning about the voice message. Such a spam voice message blocking device 100 will be described in more detail below with reference to FIGS. 2 to 3. FIG.

The calling terminal 200 is a terminal capable of transmitting a voice message. The sender terminal 200 is a terminal having a central processing unit and a memory device such as a PC, a tablet PC, a smart phone, and the like.

FIG. 2 is a block diagram illustrating a spam voice message blocking apparatus according to an exemplary embodiment of the present invention. Referring to FIG.

Referring to FIG. 2, the spam voice message blocking apparatus 100 includes a communication unit 110, a voice message management unit 120, a spam determination unit 130, and a spam voice message blocking control unit 140, And may further include a voice message storage unit 150.

The communication unit 110 may set or maintain a communication environment for receiving a voice message from the calling terminal 200 under the control of the spam voice message blocking control unit 140. [

The voice message management unit 120 may analyze the voice message received from the caller terminal 200 to generate a message string. The voice message management unit 120 may provide the generated message string to the spam voice message blocking control unit 140. [

In one embodiment, the voice message management unit 120 may convert a voice message into a text message to generate a message string. For example, when the voice message is " the possible limit for the customer is one million won ", the voice message management unit 120 converts the voice message into a text message, and the message string " Can be generated. For example, if the voice message is " 10 million won loanable access http://spam.co.kr ", the voice message management unit 120 converts the voice message into a text message and transmits a message string " http://spam.co.kr "can be created.

In another embodiment, the voice message manager 120 may generate a message string by removing a pause, which is a silence interval, from the voice of the voice message. For example, if a pause is found during the process of generating a message string, the voice message management unit 120 may temporarily stop the conversion into a text message and restart the generation of the message string when the voice is restarted.

The spam determining unit 130 may determine the voice message as a spam message by using the information of the voice message received from the calling terminal 200.

In another embodiment, the spam determining unit 130 may divide the message string into character types and determine the voice message as a spam message if the spam word is included. For example, when the message string is " 10 million won loanable access http://spam.co.kr ", the spam determination unit 130 sets 1000, quot; // spam.co.kr " and if the spam word is included in each message string, the voice message can be determined as a spam message.

The spam determination unit 130 may determine the voice message as a spam message according to the proportion of the spam word in the message string.

In one embodiment, the spam determination unit 130 generates a plurality of spam candidate words using a message string, and if the ratio of the spam word occupation among the plurality of spam candidate words is greater than or equal to a certain ratio, the voice message is determined as a spam message can do. For example, if the message string is " a loan finance consultant with no fee ", and the spam words are "commission", "loan", "finance", "consultation" Message. ≪ / RTI >

In another embodiment, the spam determination unit 130 generates a plurality of spam candidate words using a message string, and if the percentage of the spam candidate words among the plurality of spam candidate words is less than a specific ratio, It can be determined that it is not. For example, when the message string is " a call has been made to a manor call customer " and the spam word is " customer ", the spam judgment unit 130 can determine that the voice message is not a spam message.

The spam determining unit 130 may determine that the voice message is not a spam message if the telephone number of the voice message sender exists in the pre-stored contact.

The spam voice message blocking control unit 140 may control other components of the spam voice message blocking apparatus 100 to block the spam voice message.

The spam voice message blocking control unit 140 may control the spam determination unit 130 to store a voice message received from the caller terminal 200 in the voice message storage unit 150.
