PROBLEM TO BE SOLVED: To improve sound quality by suppressing a variation in sound volume and enhancing reproducibility in voice signal. SOLUTION: A voice processing device 120 has an accumulation device 152 accumulating an electric energy, a delay portion 158 delaying a detection signal which is a signal corresponding to an electric energy amount accumulated in the accumulation device to generate a control signal, a multiplication portion 150 multiplying the control signal by a voice signal inputted to the voice processing device, and an amplifier 154 receiving the electric energy accumulated in the accumulation device and amplifying the voice signal multiplied by the control signal via the multiplication portion.
