The present invention relates to a system and method for providing a voice message service which can transmit a sender's voice message to a counterpart receiver more successfully.

A general voice message providing service uses a voice mail system. Thus, when a caller calls a specific receiver but the receiver is in a state where the receiver cannot answer the call, the operator's automatic answering system (ARS) operates to output a message indicating that the call is connected to the voicemail system.

The caller listens to the guide message and saves the desired voice message in the recipient's voice mailbox. The voicemail system then sends a text message indicating that a voice message has arrived to the recipient's mobile terminal, and the recipient dials a specific phone number such as * 89 to access the voicemail system and enters his password. After authentication, listen to the voice message recorded by the caller.

According to this method, since the voice message can be recorded only in a state in which the receiver cannot answer a call, there is a disadvantage in that it cannot be used when a special voice message is to be delivered to the receiver regardless of whether the receiver terminal can be called.

Accordingly, a new type of voice message service, which is different from the above voice message service, has been developed and provided.

In this case, the caller accesses the message server of the carrier, enters the telephone number of the receiver's telephone terminal according to the guidance provided by the message server, and records the desired voice message. The message server requests the call setup from the receiver's telephone terminal at the time of sending the message requested by the caller, and when the call setup is approved by the receiver's telephone terminal, the message server connects the call and plays the caller's voice message.

Therefore, such a voice message service has a meaning in that a voice message service can be provided to a receiver at a desired point in time at the caller side without accessing the voice mailbox system.

However, even if the receiver does not listen to the sender's voice message, if the message server makes a call connection with the receiver's phone number, it is determined that the voice message has been delivered to the receiver normally, which may cause an error in transmitting the voice message to the receiver. have.

As a representative example of the above case, it is possible to consider a case where a call connection is made by driving a response system connected to a receiving telephone terminal.

As a result, the message server normally establishes a call connection with the receiver's telephone terminal and reproduces the caller's voice message, thereby causing a problem of determining that the sender's voice message is successfully transmitted to the receiver.

Accordingly, an object of the present invention is to provide a voice message service providing system and method for more intelligently checking whether a person has directly received a caller's voice message at a receiving side. .

In order to achieve the above object, the voice message service providing system according to the present invention comprises a voice analysis server that analyzes the voice data, and determines whether the voice data is voice data directly responded to a person's incoming phone call; And requesting call setup from a receiving telephone terminal at the time of transmitting the voice message requested by the caller, and when a call setting is made with the receiving telephone terminal, playing the voice message of the calling party, and receiving the voice data in response to the incoming call. Is stored for a predetermined time and transmitted to the voice analysis server, and when the voice analysis server determines that the voice data of the receiving side is not voice data directly answered by a person, the caller to the receiving telephone terminal. It comprises a; a message server for resending the voice message.

The caller receives and stores the voice message input after the caller accesses the message server through a web server or a phone terminal, the transmission time of the voice message, the retransmission time interval of the voice message, and the number of retransmissions. And a DB server for managing.

In addition, an SMS server for transmitting an SMS message for notifying the caller of the caller to the receiving telephone terminal according to the request of the message server;

In the method of providing a voice message service according to the present invention, a message server providing a voice message service requests a call setup from the receiving terminal to transmit a calling voice message to a receiving terminal, and makes a call connection with the receiving terminal. Reproducing the calling voice message, and storing the receiving voice data in response to the incoming call for a predetermined time; And transmitting the stored receiver side voice data to a voice analysis server for determining whether the message server analyzes the voice data and directly determines whether the voice data is a response from a person. And retransmitting the calling voice message to the receiving terminal when it is determined that the data is not voice data directly answered by a person.

In the present invention, the transmission of the calling voice message is characterized in that the message server requests a call setup to the receiving terminal at the time of transmitting the voice message requested by the calling party, and when the call connection is made, the calling voice message is reproduced. It is done.

In addition, the retransmission of the calling voice message requests call setup to the receiving terminal when the message server retransmits the calling voice message according to the voice message retransmission time interval and the number of information received from the calling terminal. When the call connection is made, it characterized in that to play the calling party voice message.

On the other hand, in the voice message service providing method according to the present invention, if it is determined that the stored voice data is not the voice data directly answered by a person, so that the SMS message informing the caller voice message is transmitted to the receiving terminal. And requesting an SMS from the SMS server.

Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail. However, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

1 is a diagram illustrating a voice message service providing system according to the present invention. The voice message service providing system includes a message server 100, a DB server 102, a voice analysis server 104, and an SMS server 106. It is composed of

The message server 100 is a message server 100 having an interactive voice response (IVR) function.

The message server 100 receives a telephone number and a voice message of a receiver input by a caller, and information on a time to transmit a voice message to a receiver from a telephone terminal connected through a telephone network or a web server connected through an internet network. .

In addition, the message server 100 includes a voice to speech unit (TTS: Text To Speech), and thus, when the caller inputs a text message through a telephone terminal or a web server connected to the message server, the input text message is input. Performs a service that provides a voice message by synthesizing the voice.

The speech synthesis unit reads textual data into a speech synthesized by human voice. Generally, the speech synthesis unit performs a preprocessing, morphological analysis, part-of-speech tagging, and segmentation analysis by referring to a morpheme dictionary and probability information. Rhythm generation unit that performs phrase extraction, duration adjustment, intonation and accentuation, etc., and a signal output unit that is responsible for the synthesis unit generation, voice signal synthesis and voice output, these speech synthesis techniques are widely used in related fields The detailed description thereof will be omitted.

The message server 100 further includes a voice character converting unit in addition to the voice synthesizer, so that the calling voice message can be converted into a text message.

When the message server 100 reaches the time point at which the voice message inputted by the caller is transmitted, the message server 100 requests a call setup from the telephone terminal of the receiver existing in the receiving telephone network. When receiving the call setup approval signal from the receiver's telephone terminal requesting the call setup, after establishing a call connection with the receiver's telephone terminal, the voice message transmitted by the caller is reproduced or the synthesized voice is based on the text message transmitted by the caller. It plays the message and sends the voice data packet to the receiver's telephone terminal.

At the same time, the message server 100 stores the received voice data in response to the telephone connection from the receiver telephone terminal for a predetermined time after the call connection with the receiver telephone terminal is established and transmits to the voice analysis server 104, When the voice message transmission success signal is transmitted from the voice analysis server 104, the corresponding voice message service is completed.

However, when the voice message transmission failure signal is transmitted from the voice analysis server 104, the message server 100 sets the call back to the receiver phone terminal according to the voice message retransmission time interval and the voice message retransmission number information additionally input from the caller in advance. Requests and performs voice message retransmission.

The message server 100 also requests the SMS server 106 to send an SMS message informing the caller's voice message to the recipient's telephone terminal when the voice message should be retransmitted.

Here, the SMS message informing the caller's voice message is characterized in that the message server 100 includes a message that is simply edited by converting the content of the caller's voice message into a text.

The DB server 102 transmits the receiver's telephone number and voice message input by the sender, information on when to send the voice message to the receiver, voice message retransmission time interval, and voice message retransmission information from the message server 100. Receive and store and manage functions.

The voice analysis server 104 receives the received voice data stored by the message server 100 from the receiver phone terminal. The pattern of the received voice data is analyzed to determine whether the voice data is directly received by a person in response to an incoming call or voice data output from another phone answering system.

If the voice analysis server 104 receives the voice data received from the message server 100 through voice data analysis as described above, the voice data is directly received by the message server 100. The message transmission success signal is transmitted. Otherwise, the voice message transmission failure signal is transmitted.

The SMS server 106 transmits the SMS message to the corresponding telephone terminal through the mobile communication network in response to the request for transmitting the SMS message from the message server 100.

2 is a flowchart illustrating a method of providing a voice message service according to the present invention. As shown in the figure, the calling party first accesses the message server 100 through a terminal that can be connected to the message server 100 that provides the voice message service (200).

Here, the terminal which can be connected to the message server 100 is a telephone terminal connected to the telephone network or a web server connected to the Internet network. Through such a terminal, the caller connects to the message server 100 and then the message server ( According to the guidance provided by 100), a voice message to be transmitted, a telephone number of a receiving terminal, a voice message transmission time, and a voice message retransmission time interval and number of information are input (202).

The message server 100 stores and manages the above information received from the calling terminal in association with the DB server 102 having the information storing and managing function. Although not shown in the drawing, the message server 100 sends the calling server. When a text message other than a voice message is received from the terminal, the received text message is synthesized into voice, and the synthesized voice message is stored in the DB server 102 along with other information inputted by the sender. Can provide services.

The message server 100 checks the transmission time of the voice message received from the calling terminal, and requests the call setting to the receiving terminal when the corresponding time is reached (204, 206). When receiving a call establishment request from the receiving terminal (208), the call connection with the receiving terminal (210), and the caller's voice message is reproduced (212).

At the same time, the receiving terminal directly responds to the incoming call or a response through another call answering system (214).

Accordingly, the voice data output according to the voice message reproduction of the message server 100 is transmitted to the receiving terminal, and the voice data input to the receiving terminal in response to the incoming call is transmitted to the message server 100 ( 216).

The message server 100 stores the receiving voice data transmitted from the receiving terminal for a predetermined time (218), and transmits the stored receiving voice data to the voice analysis server 104 (220).

The voice analysis server 104 analyzes the pattern of the voice data of the receiver to determine whether the voice data responded to the incoming call from the receiver terminal is voice data directly answered by a person or voice data answered by another call answering system. Determine (222).

If the received voice data is voice data directly answered by a person, the voice message transmission success signal is transmitted to the message server 100 (224, 226). Otherwise, the voice message transmission failure signal is transmitted. (224, 230).

Accordingly, when the message server 100 receives the successful voice message transmission signal from the voice analysis server 104, the message server 100 completes the corresponding voice message service (228).

On the other hand, when the message server 100 receives the voice message transmission failure signal from the voice analysis server 104, the SMS server 106 requests the SMS server 106 to transmit the SMS message informing the caller's voice message (232). The SMS notification message is transmitted to the receiving terminal through the server 106 (234).

Then, the caller checks the voice message retransmission time interval and the number of retransmission information input through the calling terminal (236,238), and the current voice message retransmission exceeds the number of voice message retransmissions input by the caller when the voice message retransmission time is reached. Only if it is not exceeded by examining whether the message server 100 requests the call setup to the receiving terminal again, the above process is repeated.

As a result, the voice message service requested by the caller to the message server 100 is confirmed by the voice analysis server 104 that the person directly responds to the incoming call on the receiving terminal, or the number of retransmission of the voice message input by the caller. When it is time to perform the retransmission in excess of is completed (240).

Although the present invention has been described in detail through the above-described exemplary embodiments, it will be understood by those skilled in the art that various modifications can be made without departing from the scope of the present invention with respect to the above-described embodiments. will be. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims below and equivalents thereof.

According to the present invention, when the voice message service providing system provides a voice message to the receiving telephone terminal, the receiving telephone terminal analyzes the receiving voice data in response to the incoming call and whether the voice data is directly answered by a person. Check whether or not. When it is confirmed that the voice data is directly answered by the person, it is possible to provide a more reliable voice message service to the user as it is determined that the voice message has been successfully transmitted to the receiver.

In addition, it is possible to provide a more intelligent voice message service by automatically determining whether the voice message is successfully transmitted through the analysis of the voice data of the receiver.
