摘要
A voice decoding apparatus includes an MBE-type decoder, a sampling convertor, a non-linear components generator and an adder. The decoder decodes digital voice-encoded information to generate a first decoded voice signal. The convertor converts the first decoded voice signal to a second decoded voice signal with a higher sampling frequency. The generator performs a non-linear process to the first or second decoded voice signal to generate an additional voice signal with the same sampling frequency as the second decoded voice signal. The additional voice signal has components in a frequency band in which the first decoded voice signal has no component and continuing to another frequency band of the first decoded voice signal. The adder adds the second decoded voice signal to the additional voice signal.
