3 is a block diagram schematically showing a mobile phone instant message transmission system according to the present invention.

As shown here, input from the sending mobile phone 15 for transmitting an instant message or voice information via the instant message protocol, the receiving mobile phone 30 for receiving the instant message, and the sending mobile phone 15 IM server 25 for transmitting the received instant message to the receiving side mobile phone 30, receiving and relaying voice information, and transmitting the converted instant message to the receiving side mobile phone 30 and the transmitting side mobile phone 15, and the IM. The voice recognition server 40 converts the voice information into an instant message and receives the voice information transmitted from the mobile phone 15 at the server 25 and transmits the voice information to the IM server 25.

The voice recognition server 40 uses automatic speech recognition (ASR) technology to analyze the voice of a person having a specific frequency by changing the shape of the mouth and the position of the tongue according to the input voice information. After converting into an electrical signal, the features of the delivered human voice are extracted and analyzed to recognize the pronunciation of the person based on the closest result from the pre-input recognition list and convert it into a character.

In addition, the transmitting side cellular phone 15 may be provided with a voice input key for notifying the start of voice information or a voice end key for notifying the end of voice information, respectively, or may be formed by one key button. Alternatively, a function may be added to a commonly used key button and used as a voice input key or a voice end key.

In this case, when the voice input key and the voice termination key are composed of one key button, the voice input key is recognized as the voice input key when the key button is pressed and the voice end key when the key button is released. It may be.

That is, for example, when the "call" button of the sender's mobile phone 15 is defined as the voice input key and the voice end key, when the "call" button is pressed in the mode for creating an instant message, the voice input key is recognized as the voice input key. If you accept the call and release or press the "call" button again, it will be recognized as the voice end key and it will be judged that the voice input is over. On the other hand, if the voice end key is not input even after a certain time elapses after the voice input key is input, the voice input key stops by inputting the voice end key by operation so that a large amount of untrusted voice information is not input. You may.

As described above, when the user inputs the instant message in the voice message from the sender's mobile phone 15 through the voice input key or the voice end key, the start and end of the message can be precisely classified to improve the voice recognition rate.

Therefore, when the instant message information is input by voice in the mobile phone 15 of the transmitting side, the IM server 25 receives it and converts the voice information into instant message information composed of texts through the voice recognition server 40 to receive the information. The instant message is transmitted by transmitting the mobile phone 30 so that an instant message can be transmitted even if a character is not input by a key button. Allows you to check whether the message matches.

Referring to the flowchart illustrated in FIG. 4, a method of transmitting a mobile phone instant message through the mobile phone instant message transmission system is as follows.

First, it is determined whether there is a voice input key input to be used when an instant message is input by voice from the transmitting mobile phone 15 (S10).

This is to solve the problem that it is difficult to grasp the starting point of the voice information input by the instant message from the inputted voice information by inputting the voice input key first and then inputting the voice information when the instant message is input by voice. In addition, in order to accurately recognize and separate the input voice information, it is necessary not only to analyze a large amount of voice information, but also to solve a problem that takes a long time for analysis. After inputting the key, the user inputs a voice to send an instant message.

At this time, the voice information is coded by an enhanced variable rate codec (EVRC) or a vocoder (Quocomm Code Excited Linear Prediction) or a voice initiation protocol (SIP) protocol or IMMP (Instant Messaging and Presence) for transmitting an instant message. It is uploaded to payload of Protocol and transmitted.

In addition, the voice termination key may be added to define a section in which the voice is input so that the voice information can be correctly recognized.

When the voice input key is not input after determining whether the voice input key is input as described above, it is generally determined that the instant message is input by using the key button, and the mobile terminal 30 transmits the received instant message. (S12) (S20).

However, if there is an input of the voice input key, after receiving the voice information (S14), the voice information is relayed to the voice recognition server 40 by the voice recognition server 40 and the voice input by the voice recognition technology. By converting the information into text to complete the instant message is sent to the IM server 25 (S16).

At this time, when the voice end key is input after receiving the voice information, the voice information is relayed to the voice recognition server 40 to convert the voice information into text, thereby clearly defining the interval of the voice information, thereby recognizing the voice recognition rate and the voice recognition. You can also save time.

In this way, the IM server 25 transmits the instant message converted by the voice recognition server 40 to the sender's mobile phone 15 so as to confirm whether the input voice information has been correctly converted and to the receiver's mobile phone 30. Transmitting the instant message is performed (S18) (S20).

When the voice message is inputted by pressing the voice input key or pressing the voice end key on the sender's mobile phone 15, the IM server 25 and the voice recognition server 40 transmit the voice information transmitted through the instant message protocol. By converting the input voice information into text information, the instant message is transmitted to the receiving mobile phone 30 and the transmitting mobile phone 15 so that the instant message can be transmitted through voice.

As described above, when the user inputs the voice message in the mobile phone, the present invention converts the voice into a text in the voice recognition device so that the voice message can be received and transmitted as an instant message without having to press a complicated key button to make a text. The advantage is that you can simply create and send an instant message.

In addition, by installing the voice recognition device on the IM server side without attaching it to the mobile phone, it is possible to easily send instant messages by voice by simply inputting the key to input the voice input from any mobile phone, even if an expensive voice recognition device is not applied to the mobile phone. There is an advantage.
