Abstract: A method for inserting vector information for predicting voice data of a key re-synchronization section, a transmission method and a method for predicting voice data of a key re-synchronization section using vector information are provided to predict a voice data value of a mute section by periodical key re-synchronization in direction wireless environment by using characteristics of a voice data value showing smooth variation, thereby improving communication quality in a receiving terminal. An inputted voice is encoded as voice data(200,210). It is determined whether a frame of voice data to be transmitted is a key re-synchronization point(220). If so, voice data of a current frame is deleted(230). From a difference between voice data of a previous frame and the voice data of the current frame, voice change direction information is obtained(231). By using the extracted voice change direction information of the voice data, vector information is configured(232). The vector information and key re-synchronization information are inserted into a section where the voice data is deleted in order to configure a key re-synchronization frame(233). After that, the configured key re-synchronization frame is transmitted(234).
