<p>A mobile communication terminal with a voice decoding function and an operating method thereof are provided to independently output a low-band voice and a high-band voice from received voice data to synthesize the outputted voices, thereby realizing a virtual wideband voice to provide a high-quality voice. A voice decoder(120) restores sampled voice data. A voice generator(130) generates virtual voice data by using inputted noise and voice parameters of the voice data. A voice synthesizer(140) adds the voice data restored through the voice decoder(120) to the virtual voice data outputted from the voice generator(130) to output a voice. The voice generator(130) comprises as follows. An HPF(High Pass Filter)(132) filters the inputted noise. An LPC(Linear Prediction Coding) synthesis filter(131) filters a noise signal through parameters of the voice data, and generates a voice signal. A gain matching unit(133) matches the voice signal with a gain of the voice data.</p> |
