The first conversion encoding unit encodes the converted input signal. When the input signal is a voice feature signal, an LPC(Linear Predictive Coding) encoding unit(130) encodes the input signal based on LPC. A bit stream generating unit(140) generates a bit stream using output signals of the first conversion encoding unit and the LPC encoding unit.
