Abstract: PURPOSE: A method for normalizing voice signals in a vocoding system of a mobile communication terminal is provided to divide a voice into a voiced sound and an unvoiced sound and to differently normalize the voiced and the unvoiced sound, so as to reduce calculation amounts to perform a real-time processing. CONSTITUTION: A vocoding system divides encoded voice signals according to frames, and windows the divided voice signals(S201). The vocoding system decides whether the windowing signals are voiced sounds or unvoiced sounds, according to parsing rate information(S202). If a presently-normalized frame is an unvoiced part, the vocoding system divides the corresponding frame into optional constant values to find an energy value(S203,S207). If the presently-normalized frame is a voiced sound, the vocoding system finds a value having a biggest absolute value among voice sample values, in a quarter spot, a half spot, and a three-quarter spot(S204). The vocoding system multiplies a maximum value of the voice sample values by 1.5, and divides the voice sample values with the multiplied maximum value, then normalizes the voice sample values(S205). The vocoding system cuts a voice sample having a bigger value than the multiplied maximum value, and takes an energy value with the multiplied maximum value(S206,S207).
